OVO SEG Install Exclusive is the supplier's highest-paying domestic Smart Export Guarantee tariff. It currently pays 20 pence per kilowatt hour where OVO installed both the solar panels and home battery. Customers whose solar panels were installed by OVO without battery storage can receive a lower Install Exclusive rate of 15 pence per kilowatt hour. The household must also buy its imported electricity from OVO, use an eligible pay-monthly account and have installed generation capacity below 30 kilowatts. The exclusive rate is fixed for its first twelve months. This guide was checked on 11 July 2026.
Solar panels first supply electricity being used within the home. Surplus generation can charge the household battery where one is installed. Electricity that remains after household demand and battery charging can pass through the export meter into the public network. OVO pays for each eligible kilowatt hour recorded as leaving the property. A solar-and-battery customer receiving 20p per kilowatt hour would earn: A solar-only customer receiving 15p would earn: These figures relate to measured export, not total solar generation. Electricity used directly inside the property does not pass through the export meter and does not receive a SEG payment.
The full 20p rate is available where OVO installed both the qualifying solar panels and battery storage. Where OVO installed the solar panels but no home battery, the current Install Exclusive rate is 15p per kilowatt hour. The household must meet the remaining tariff conditions in either case. Adding battery storage does not necessarily mean the household will export more electricity. A battery often increases self-consumption by storing daytime solar generation for use during the evening. However, the battery package unlocks the higher export price. The customer must therefore compare the additional battery purchase cost with several possible benefits: Reduced daytime and evening grid imports Increased use of solar generation inside the home Potential backup capability Access to the additional 5p export payment The difference between 15p and 20p is worth £50 for every 1,000 kWh exported. At 2,500 kWh of annual export, the higher rate produces an additional £125 a year. That difference alone is unlikely to repay the complete cost of a home battery quickly. The wider savings from reducing grid purchases are usually more important.
SEG Install Exclusive is restricted to qualifying installations completed through OVO. A customer whose solar panels and battery were installed by another company does not qualify merely because the equipment is technically similar. An existing renewable-energy owner supplied by OVO may instead qualify for SEG Beyond Exclusive at 12p per kilowatt hour. OVO says customers should apply after the installation is complete and final payment for the equipment has been received. OVO normally sends the customer an email containing sign-up details once these stages have been completed. The installation must be in an area where OVO's solar-installation service is available. It must also meet the relevant OVO installation terms and Smart Export Guarantee requirements.
The household's imported electricity must be supplied by OVO. This does not mean the import and export arrangements are the same contract. OVO's SEG terms state that the export agreement is legally separate from the household electricity-supply contract. However, remaining an OVO electricity customer is a condition of receiving the Install Exclusive rate. If the customer moves their import supply to another energy company, they will no longer meet the exclusive tariff conditions. OVO can then move the export account to its standard SEG tariff or another applicable rate. The standard OVO SEG rate is currently 4p per kilowatt hour, meaning that leaving OVO could cause a substantial reduction in export income. The household should therefore compare the complete import-and-export package before changing supplier. A saving on imported electricity elsewhere could outweigh the reduction in export income, particularly where the household exports relatively little. A large solar installation exporting several thousand kilowatt hours may produce the opposite result.
SEG Install Exclusive is available to eligible OVO pay-monthly customers. OVO's current terms require the customer to pay for their energy supply by Direct Debit. The product is not available as an exclusive export arrangement for a household using an OVO Pay As You Go energy account. Payments are credited to the customer's OVO energy account rather than being automatically transferred to a separate bank account. The export credit appears as "SEG" on the statement and within the OVO app. Provided the energy account is not in debit, the customer may be able to ask OVO to return surplus credit, subject to the account and payment conditions.
The installed generation capacity must be below 30 kilowatts. Most ordinary domestic rooftop systems fall well within this limit. For example, twelve 440-watt panels would provide a peak array capacity of approximately 5.28 kilowatts. The 30kW threshold could matter for a large rural home, estate, farm property or building with an unusually extensive solar array. Customers must inform OVO if they add panels, replace equipment or make another alteration that changes the installation capacity. If the revised system exceeds the tariff limit, the export rate can change and OVO may require a new SEG agreement.
A communicating smart meter is required. The meter must be capable of measuring electricity exported from the property at half-hourly intervals. The export supply must also have its own Meter Point Administration Number, normally called an export MPAN. The import MPAN identifies electricity entering the property. The export MPAN identifies electricity sent to the network. Both registers may be contained within the same physical smart meter, but they are treated separately in industry settlement and tariff administration. If the property does not already have an export MPAN, OVO can arrange for one to be created. If the customer is moving from another SEG provider, the existing export MPAN can be transferred. OVO says an application could become active in around four weeks when all documents and meter information are available. Missing information or communication problems can make the process longer.
The installation must normally hold MCS or Flexi-Orb accreditation. OVO's terms say it may accept an installation without those accreditations where suitable documents confirm the commissioning date, technology type and total installed capacity. Eligibility would need to be assessed from the evidence provided. OVO may request: Proof that the customer owns the system A paid installation invoice The MCS or equivalent certificate The distribution-network documentation A photograph of the export-meter register The meter serial number A battery schematic or line diagram The battery diagram should show how electricity can move between the solar panels, battery, household loads and grid. OVO specifically advises battery customers that this information may be required. For systems above the relevant connection threshold, the installer must also complete the applicable G98 or G99 process with the local distribution network operator.
SEG payments do not necessarily begin when the panels are installed or when the online application is submitted. Under OVO's terms, eligibility for payment begins when the first export meter reading has been received and validated. OVO then confirms the tariff and start date. Electricity exported before the accepted commencement date may not receive Install Exclusive payments. Customers should retain: The tariff welcome letter The confirmed export rate The start date The opening export reading The export MPAN Copies of all installation documents These records can help resolve a missing payment or incorrect start date.
The SEG Install Exclusive rate is fixed for the first twelve months. After that period, OVO may reduce the rate so that it is aligned with SEG Beyond Exclusive. If OVO decides to lower it, the customer must receive at least 28 days' notice. The current Beyond Exclusive rate is 12p per kilowatt hour. A solar-and-battery customer could therefore move from 20p to 12p after the first year. A solar-only customer could move from 15p to 12p. The first-year rate should not be used as a permanent assumption in a twenty-year solar investment calculation. A realistic projection should model: The guaranteed first-year Install Exclusive rate A lower export rate from year two onwards Possible future tariff changes Changes in annual generation Gradual panel degradation Changes in household consumption
OVO normally processes export meter readings four times a year, in March, June, September and December. Payment is usually added approximately eight weeks after the relevant meter-reading window closes. Where the smart meter communicates correctly, readings should be collected automatically. If OVO cannot obtain a reading, it may ask the customer to provide one manually. The customer must normally respond within seven calendar days. Estimated readings are not accepted. Where a reading is missing or cannot be validated, the payment is carried forward until OVO receives complete and acceptable meter data. Customers should periodically photograph the export register and compare the readings with the credits shown in the OVO account.
A household cannot receive both a Feed-in Tariff export payment and an OVO SEG payment for the same exported electricity. An existing FIT customer may give up the export element and continue receiving the FIT generation payment, subject to the scheme rules. OVO states that customers can normally opt in or out of FIT export only once during a twelve-month period. This decision needs care. Older FIT installations can receive deemed export payments based on an assumed proportion of generation. SEG pays according to electricity actually measured as leaving the property. A household using most of its solar generation may export less than the deemed calculation assumes. The value of the historic arrangement should be established before it is surrendered.
Battery storage can hold solar electricity and release it later. Solar energy stored in the battery before being exported may form part of the eligible renewable export. However, electricity purchased from the grid, stored and later discharged is not automatically treated as qualifying solar export. OVO's terms describe non-renewable or grid-originated export as "brown export". OVO is not generally obliged to make ordinary SEG payments for that electricity unless the customer participates in a separate programme that expressly permits it. Customers should not assume they can buy cheap grid electricity, export it at 20p and retain the difference. The battery installation and meter data must allow OVO to understand where the exported electricity came from.
A 20p export rate is strong, but using solar electricity inside the home may still be worth more. Suppose the household pays 27p per kilowatt hour for imported electricity. Using one solar unit directly avoids spending 27p. Exporting the same unit earns 20p. Direct use is worth 7p more in that example. At the 15p solar-only rate, direct use would be worth 12p more. The financial priority will often be: Use solar electricity directly Charge the battery for later household use Export genuine surplus generation The calculation may change where the customer has access to cheap managed EV charging or another specialist import arrangement.
OVO's current household export rates are: ------------------------------------------------------------------------- Tariff Current Main requirement rate --------------------------- ----------- --------------------------------- Standard SEG 4p per kWh Import supply can be elsewhere SEG Beyond Exclusive 12p per kWh Electricity supplied by OVO Install Exclusive, solar 15p per kWh Solar panels installed by OVO only Install Exclusive, solar 20p per kWh Solar panels and battery and battery installed by OVO ------------------------------------------------------------------------- At 2,500 kWh of annual export, the payments would be: The highest rate produces £400 more than standard SEG at that export level. The customer must balance that difference against the cost of the installation, OVO import prices and the possibility of the exclusive rate reducing after twelve months.
The customer can end an OVO SEG agreement at any time by notifying OVO in writing and providing a final export reading. The agreement also provides a 14-day cooling-off period after sign-up. Moving home ends the export arrangement because the solar and battery equipment normally remains at the property. OVO asks for at least 28 days' notice of a change in ownership and a final meter reading. The new owner must apply for their own SEG contract because the existing agreement does not transfer automatically. The new owner should not assume they will receive the same Install Exclusive rate. Eligibility is linked to the applicable product terms and customer circumstances.
OVO SEG Install Exclusive is most suitable for a household purchasing a new solar installation directly through OVO and willing to keep its imported electricity with the company. The 20p rate is especially attractive where the customer also buys battery storage, the system generates a substantial surplus and the household can satisfy the metering and documentation requirements. The tariff may be less suitable where the OVO installation is substantially more expensive than an alternative installer, where the household exports very little or where another supplier offers a much cheaper import tariff. The first-year rate should not be viewed separately from the equipment purchase. The correct calculation includes: The installed cost of solar and battery equipment Finance charges where applicable Reduced electricity imports Battery losses and degradation Export income during the first twelve months A reasonable export-rate assumption after year one Maintenance and inverter replacement OVO SEG Install Exclusive offers one of the strongest rates in OVO's export range. Its 20p headline rate can produce valuable first-year income, but it is an installation-linked incentive rather than a permanent guaranteed return.
The Octary OVO comparison page should determine which OVO household tariff and optional services are most suitable for an individual property. It should not simply rank products using the lowest advertised price. OVO's product structure is different from suppliers offering whole-home overnight tariffs. Its current Charge Anytime service discounts or includes qualifying electric vehicle charging while the rest of the household remains on a standard OVO supply tariff. A customer may therefore have several simultaneous arrangements: 1. An electricity and gas supply tariff 2. A Charge Anytime EV plan 3. A Smart Export Guarantee tariff 4. Boiler cover 5. Greener Electricity 6. OVO Beyond and Power Move rewards The comparison engine must assemble valid combinations rather than treating every OVO product as a direct alternative. For example, a customer could use: The correct recommendation depends on the total annual cost and practical suitability of the complete package. The system should consider:
The principal comparison should include 13 OVO products.
1. OVO Simpler Energy 2. OVO 1 Year Fixed 3. OVO 1 Year Fixed Plus Boiler Cover 4. OVO 1 Year Fixed Plus Greener Electricity 5. OVO 2 Year Fixed
6. Charge Anytime Pay As You Go 7. Charge Anytime Standard 8. Charge Anytime Premium 9. Charge Anytime Standard Plus 10. Charge Anytime Premium Plus
11. OVO Smart Export Guarantee 12. OVO SEG Beyond Exclusive 13. OVO SEG Install Exclusive
The following should be modelled separately but should not be ranked as complete tariffs: Battery Boost is no longer available from 1 February 2026 and should be kept only as a legacy product record. Heat Pump Plus also closed to new participation from 1 February 2026 and should not appear as a current recommendation.
From 1 July to 30 September 2026, the average Direct Debit price-cap rates across England, Scotland and Wales are: ----------------------------------------------------------------------- Charge National average ------------------------------------------ ---------------------------- Electricity unit rate 26.11p per kWh Electricity standing charge 57.19p per day Gas unit rate 7.33p per kWh Gas standing charge 29.04p per day ----------------------------------------------------------------------- These figures include VAT and are national averages rather than exact OVO tariff prices for every property. Regional distribution charges, meter configuration and payment method can change the rate offered to an individual household. The comparison engine must not use a supplier's headline "typical annual bill" as the customer's predicted bill. It should calculate cost from:
Every OVO entry should be assigned a system classification. ------------------------------------------------------------------------- Classification Meaning -------------------- ---------------------------------------------------- Standard variable Unit rates can change with regulated pricing Fixed supply Unit rates and standing charges fixed for a term Bundled fixed supply Fixed tariff combined with another product EV charging modifier Credits qualifying EV charging without changing all household electricity EV subscription Monthly charging allowance and additional benefits Export tariff Pays for eligible renewable electricity sent to the grid Insurance product Boiler or charger protection under separate terms Environmental Renewable electricity matching or support upgrade Reward programme Prizes, credits or temporary benefits Legacy product Closed and retained only for historical comparisons ------------------------------------------------------------------------- OVO Charge Anytime must never be represented as an ordinary time-of-use tariff. It does not give the entire household a low electricity rate during fixed overnight hours. It uses charging data from a compatible vehicle or charger to identify qualifying EV consumption and then applies a credit or monthly-plan allowance.

Type: Standard variable electricity and gas tariff Contract: Open-ended Exit fee: None Price changes: Variable Smart meter required: Not necessarily for basic supply Simpler Energy should be used as OVO's flexible baseline tariff. Its regional unit rates and standing charges can change. It does not protect the customer against future increases, but it allows the household to switch without a tariff exit charge. It may suit: It may be less suitable for:
For electricity: Annual electricity cost = annual electricity kWh × regional unit rate + 365 × daily electricity standing charge For gas: Annual gas cost = annual gas kWh × regional gas rate + 365 × daily gas standing charge The comparison should use the customer's postcode quotation or current tariff rates rather than national averages.
Type: Fixed electricity and gas tariff Contract: 12 months Exit fee: £50 for each fuel Charge Anytime compatible: Yes Greener Electricity available: Yes Boiler cover available separately: Yes OVO fixes the unit rate and standing charge for each supplied fuel for twelve months. The total bill remains dependent on consumption. A dual-fuel customer could face an early exit cost of £100. The tariff may suit: It may be less suitable where:
First-year cost = annual fixed energy cost + current supplier exit fees + one-time joining costs When comparing a mid-contract switch: Effective saving = alternative tariff saving − OVO exit fees
Type: Fixed supply tariff and separate boiler-insurance product Contract: 12 months for the energy tariff Energy exit fee: £50 for each fuel Advertised first-year energy saving: £100 compared with the associated offer
OVO advertises a £100 first-year energy-bill saving with the boiler-cover tariff. It also offers three levels of protection. The energy tariff and insurance should be modelled as separate contracts. The comparison must collect: Current standalone cover can include £0, £60 or £95 claim excesses. Essentials covers the boiler and central heating; Starter adds plumbing and electrics; Complete adds wider services such as qualifying boiler replacement and drainage cover. The system must not automatically value cover at its full retail price. A customer who already has equivalent protection may receive little additional value.
Annual package cost = annual energy cost + boiler-cover premiums + expected claim excesses Expected claim cost can be estimated as: Expected excess cost = probability of eligible claims × excess per claim The output should also show the cost without assigning speculative value to insurance.
Type: Fixed supply tariff with renewable-electricity upgrade Contract: 12 months Exit fee: £50 for each fuel Greener Electricity cost: £80 for the year OVO describes this as twelve months of Greener Electricity for the usual price of ten months. The standalone upgrade currently costs £8 a month, while the bundled tariff includes it for £80 over the twelve-month contract. OVO says it purchases renewable electricity through UK Power Purchase Agreements and associated Renewable Energy Guarantees of Origin to match participating customers' use. It also contributes £40 per qualifying customer each year towards supporting independent UK renewable generation. The tariff does not:
Annual package cost = annual fixed energy cost + £80 The comparison should separately display: Environmental preference should influence suitability but should not silently override the annual-cost ranking.
Type: Long-term fixed electricity and gas tariff Contract: 24 months Exit fee: £95 for each fuel Charge Anytime compatible: Yes OVO's two-year product fixes unit rates and standing charges for 24 months and currently has a £95-per-fuel early exit charge. A dual-fuel household could face £190 in total exit fees. It may suit: It may be unsuitable where:
The system should show both years rather than multiplying a one-year estimate without explanation. Two-year cost = year-one consumption × fixed rates + year-two consumption × fixed rates + two years of standing charges Alternative variable tariffs should be compared using at least three scenarios: The customer should see the potential protection and the opportunity cost of fixing.
Charge Anytime is an EV charging add-on available on compatible OVO pay-monthly tariffs. The basic eligibility requirements include: OVO currently supports SMETS2 meters and Secure-manufactured SMETS1 meters where they communicate correctly. Only one compatible vehicle or charger connection route is required. The engine should return one of these compatibility results: 1. Compatible through vehicle 2. Compatible through charger 3. Compatible through both 4. Solar-compatible charger required 5. Compatibility uncertain 6. Ineligible Compatibility must be checked against OVO's current list whenever the comparison is run because supported vehicles and chargers can change.
Subscription: None Effective smart-charging rate: 14p per kWh Maximum monthly credit: £100 per account Urgent charging: Household tariff rate Other household electricity: Household tariff rate Under Pay As You Go, all electricity is initially billed at the ordinary OVO tariff rate. OVO later credits qualifying smart EV consumption so its effective rate becomes 14p per kWh.
Smart EV cost = qualifying smart-charging kWh × £0.14 Urgent charging cost = urgent-charging kWh × household unit rate Offline or ineligible charging cost = affected kWh × household unit rate Total EV cost = smart EV cost + urgent cost + offline cost
The maximum monthly credit is £100. The discounted-consumption threshold depends on the household electricity rate. Credit per smart-charged kWh = household unit rate − £0.14 Maximum smart kWh before cap = £100 ÷ credit per kWh At a household rate of 26.11p: Credit per kWh = 26.11p − 14p = 12.11p Maximum smart consumption before £100 cap ≈ 826 kWh The engine must calculate this separately for every month if the household rate changes.
For every monthly plan, the system must calculate: 1. Annual subscription cost 2. Home charging inside the allowance 3. Home charging above the allowance 4. Urgent charging 5. Public-charging voucher actually used 6. Charger-cover value 7. Battery-health value 8. Kwik Fit discount value 9. Unused allowance 10. Lost benefits if the customer cancels Unused home-charging allowance does not roll forward. Charging above the monthly allowance and urgent charging are billed at the household tariff rate. Customers can change plans, but plan changes generally take effect at the end of the month.
Fee: £27.50 per month Allowance: 175 kWh per month Annual maximum: 2,100 kWh Public voucher: £120 per year Included: EV charger cover OVO's mileage estimate is approximately 700 miles a month based on four miles per kWh.
At full use: £27.50 ÷ 175 kWh = 15.71p per kWh Before valuing the public voucher and charger cover, Pay As You Go at 14p is cheaper for the same quantity. The plan becomes competitive where the customer uses:
Fee: £37.50 per month Allowance: 250 kWh per month Annual maximum: 3,000 kWh Public voucher: £120 per year
At full use: £37.50 ÷ 250 kWh = 15p per kWh Premium is aimed at approximately 1,000 home-charged miles per month under OVO's four-miles-per-kWh assumption.
Fee: £59.50 per month Allowance: 350 kWh per month Annual maximum: 4,200 kWh Public voucher: £240 per year
At full use: £59.50 ÷ 350 kWh = 17p per kWh The higher apparent home-charging price is offset partly by the larger public voucher and additional services. It is primarily relevant to:
Fee: £79.50 per month Allowance: 500 kWh per month Annual maximum: 6,000 kWh Public voucher: £240 per year
At full use: £79.50 ÷ 500 kWh = 15.9p per kWh OVO markets the plan towards approximately 2,000 home-charged miles a month using its four-miles-per-kWh assumption. It should not be recommended merely because the household has two EVs. The combined monthly charging requirement must regularly approach the 500 kWh allowance.
The engine should not automatically subtract the complete advertised value of every benefit.
Voucher value used = minimum of annual voucher and expected qualifying public-charging spend A customer expecting £40 of public charging should not be given a £120 saving merely because the plan includes a £120 voucher. Public-charging inputs should include:
Assign one of these values: Use zero where: Expected claim cost should include the applicable excess.
Assign value only where the customer would reasonably purchase an assessment. It may be more relevant where:
The benefit value should be calculated from the customer's likely subscription cost. Tyre discount value = expected Kwik Fit subscription expenditure × 15% If the customer does not want the subscription, its value is zero.
For each month: Included smart kWh = minimum of qualifying smart kWh and plan allowance Excess smart kWh = maximum of qualifying smart kWh − plan allowance, zero Monthly EV cost = monthly plan fee + excess smart kWh × home rate + urgent kWh × home rate + offline kWh × home rate Annual value: Annual net plan cost = sum of monthly EV costs − public voucher used − accepted perk value The result should show:
The system must support multiple vehicles. For each EV, collect: ----------------------------------------------------------------------- Variable Type -------------------------------------- -------------------------------- Make and model Text Battery electric or plug-in hybrid Choice Battery capacity kWh Usable capacity kWh Annual mileage Miles Efficiency Miles per kWh Charging efficiency Percentage Home charging share Percentage Workplace charging share Percentage Public charging share Percentage Monthly mileage distribution Miles Charger make and model Text Charger power kW Internet connection Yes or no OVO compatibility Confirmed, uncertain or no Solar-compatible charger Yes or no Typical plug-in time Time Required departure time Time Urgent charges per month Number Public charging spend Pounds Number of EVs sharing charger Integer Manufacturer-specific offer Details -----------------------------------------------------------------------
Vehicle battery energy = annual mileage ÷ vehicle efficiency Grid energy = vehicle battery energy ÷ charging efficiency Home EV grid energy = grid energy × home charging proportion Example: 12,000 ÷ 3.5 ÷ 0.90 × 0.80 = approximately 3,048 kWh This consumption must be distributed by month because Charge Anytime allowances reset monthly.
Charge Anytime credits apply only to qualifying electricity imported from the grid. Solar electricity entering the vehicle directly is excluded from the OVO credit because the customer did not buy that electricity from OVO. Solar customers need a suitable solar-compatible charger connection, and some installations may require a current-transformer clamp. The system should divide EV charging into: Solar charging should be valued at its opportunity cost. Solar EV value = avoided grid cost − export income forgone If the household would otherwise export solar electricity at 12p but avoids purchasing 26p electricity by charging the car, the net value of direct solar use is approximately 14p per kWh before charging losses.
Rate: 4p per kWh Import supplier: Any provider Capacity: Up to 5 MW, or 50 kW for micro-CHP Payment destination: Bank account This is OVO's supplier-independent export option.
The 4p rate is substantially below OVO's exclusive rates.
Export income = eligible exported kWh × £0.04 ----------------------------------------------------------------------- Export Annual income ---------------------------- ------------------------------------------ 1,000 kWh £40 2,500 kWh £100 4,000 kWh £160 -----------------------------------------------------------------------
Rate: 12p per kWh Import supplier: OVO Capacity: Under 30 kW Beyond membership: Required Payment destination: OVO energy account OVO describes SEG Beyond Exclusive as the option for customers supplied by OVO whose renewable system remains under 30 kW.
Export income = eligible exported kWh × £0.12 ----------------------------------------------------------------------- Export Annual income ---------------------------- ------------------------------------------ 1,000 kWh £120 2,500 kWh £300 4,000 kWh £480 -----------------------------------------------------------------------
The comparison must show the possible loss of export income if the customer moves their import supply away from OVO. For 2,500 kWh of annual export: An alternative supplier's import tariff should therefore save more than £200 before the switch becomes beneficial, assuming all other costs remain equal.
Rate with OVO-installed solar only: 15p per kWh Rate with OVO-installed solar and battery: 20p per kWh Import supplier: OVO Capacity: Under 30 kW Installer: OVO OVO's current export page states that qualifying solar-only installations receive 15p and qualifying solar-and-battery installations can receive up to 20p.
Export income = eligible export × £0.15 ----------------------------------------------------------------------- Export Annual income ---------------------------- ------------------------------------------ 1,000 kWh £150 2,500 kWh £375 4,000 kWh £600 -----------------------------------------------------------------------

It should include:
----------------------------------------------------------------------- Variable Purpose --------------------------------- ------------------------------------- Renewable technology Determines SEG eligibility Array or generation capacity Applies capacity limits Annual generation Predicts available electricity Annual measured export Predicts income Smart export meter Required for measured export Export MPAN Identifies export supply MCS or equivalent certification Installation evidence DNO notification or approval Network compliance Battery installed Affects export and documentation Battery schematic May be required Existing SEG supplier Transfer requirement Existing export rate Baseline FIT generation payment Historical arrangement FIT export payment Cannot overlap with SEG Deemed or metered FIT export Important financial comparison Import supplier Exclusive-rate eligibility OVO-installed equipment Install Exclusive eligibility OVO Beyond joined Beyond Exclusive eligibility Public grant received Check SEG conditions Ownership evidence Required for application ----------------------------------------------------------------------- OVO asks applicants for an MCS-certified or equivalent system, a smart export meter and battery schematics where battery storage is present.
The system must identify whether a customer receives: A customer cannot receive two export payments for the same electricity. The comparison should calculate: Current FIT export income = deemed or measured export × FIT export rate Proposed SEG income = measured export × SEG rate Deemed export may be more valuable than measured SEG where the household consumes most of its solar generation. The interface should warn: Changing from deemed FIT export to measured SEG can have long-term consequences. Confirm the effect with the existing FIT licensee before making a change.
For each generated kilowatt hour, compare: Value of direct use = import price avoided Value of export = SEG rate Value of battery storage = avoided later import − storage losses − degradation cost Example: Directly using one solar unit avoids 26p, while exporting earns 12p. Direct-use advantage = 14p per kWh For Install Exclusive at 20p: Direct-use advantage = 6p per kWh The result can change where: The engine must not assume that exporting is always best merely because the export rate is high.
Although OVO no longer offers Battery Boost, battery storage remains important to the solar and export model. Collect: ----------------------------------------------------------------------- Variable Unit --------------------------------------- ------------------------------- Battery capacity kWh Usable capacity kWh Charge power kW Discharge power kW Round-trip efficiency Percentage Minimum reserve Percentage Grid charging allowed Yes or no Battery export allowed Yes or no DNO export limit kW Solar-only charging mode Yes or no Annual cycles Number Warranty throughput MWh Estimated degradation cost Pence per cycled kWh -----------------------------------------------------------------------
Returned energy = charged energy × round-trip efficiency A battery charged with 10 kWh at 90% efficiency returns approximately 9 kWh. Battery export calculations should include: The engine must not assume that grid electricity stored and later exported qualifies for renewable SEG payments.
Standalone Greener Electricity currently costs £8 a month. The system should allow it to be added to eligible OVO plans independently of the dedicated £80 fixed bundle. OVO says the upgrade matches electricity use through UK Power Purchase Agreements and makes a £40 annual contribution supporting new independent renewable generators.
Annual standalone cost = £8 × 12 = £96
£96 − £80 = £16 The £80 fixed bundle is therefore £16 cheaper over a complete year than twelve standalone monthly payments at the present price. The engine should ask:
The system should support: Collect: ----------------------------------------------------------------------- Variable Purpose ------------------------------------- --------------------------------- Customer owns property Product eligibility Boiler fuel Cover eligibility Boiler age Failure and replacement risk Boiler make and model Eligibility Existing warranty Avoid duplicate cover Annual service already arranged Avoid duplicate value Chosen excess Claim cost Cover premium Annual package cost Expected claims Risk modelling Existing overlapping protection Reduce attributed value Likelihood of moving Contract suitability ----------------------------------------------------------------------- The comparison must show two results: 1. Pure financial energy-tariff comparison 2. Combined tariff and insurance comparison A boiler bundle should not win the energy ranking solely because the engine assigned an unrealistic full retail value to insurance the customer did not want.
OVO Beyond and Power Move should be classified as rewards rather than guaranteed tariff discounts. Power Move currently rewards customers through prize opportunities for shifting electricity away from weekday peak periods, presently described as 5pm to 7pm. Because rewards can change and prize draws are uncertain, the default annual-value assumption should be zero. The interface may show: OVO has also offered two hours of free electricity each week. The offer running from 18 May to 2 August 2026 excludes EV charger, battery and heat-pump consumption and limits qualifying use to 1 kWh per hour.

Annual cost = annual kWh × unit rate + 365 × standing charge
Annual supply cost = electricity cost + gas cost
Fixed cost = consumption × fixed unit rates + fixed standing charges
Break the forecast into price periods: Variable cost = Σ consumption during price period × applicable rate + standing charges
First-year net cost = tariff cost + current exit fee + new-product charges − export income − confirmed rewards
Exclude one-time switching fees and temporary introductory benefits unless they recur.
Net household energy cost = electricity import cost + gas cost + standing charges + Charge Anytime fees + Greener Electricity cost + boiler-cover premiums + expected excess costs − Charge Anytime credits − SEG income − guaranteed bill credits The comparison should provide at least: 1. First-year cost 2. Ongoing annual cost 3. Two-year cost where relevant 4. Cost excluding optional insurance 5. Cost including optional insurance 6. Cost with and without environmental upgrades 7.

The result should explain the recommendation in ordinary language.
Your household uses approximately 3,000 kWh a year for home EV charging. This closely matches Premium's annual maximum allowance of 3,000 kWh. You also expect to spend at least £120 a year on compatible public charging, so the included voucher is likely to be used in full. Your solar array exports approximately 2,200 kWh a year. Because OVO would supply your household electricity and your installation is below 30 kW, you appear eligible for SEG Beyond Exclusive at the current 12p rate. Estimated household electricity and gas cost: £X\ Charge Anytime subscription: £450\ Public voucher expected to be used: £120\ Estimated SEG income: £264\ Estimated net annual cost: £Y\ Saving against current arrangement: £Z\ Price certainty: High for one year\ Result confidence: High
- Charge Anytime Standard was rejected because its 175 kWh monthly allowance is below your regular charging requirement. - Standard Plus was rejected because you would leave too much of its 350 kWh allowance unused. - Pay As You Go was close in cost, but Premium was stronger after including the public voucher and battery-health benefit you said you would use. - Two Year Fixed was rejected because you expect to move within eighteen months. - OVO standard SEG was rejected because you qualify for the higher Beyond Exclusive rate. - SEG Install Exclusive was rejected because OVO did not install your solar panels.

The database should preserve closed OVO products but clearly mark them unavailable. Legacy records should include: Legacy products may be useful when analysing a customer's current contract, but they should not appear as new recommendations.
The best OVO arrangement is determined by the interaction between the household tariff and its additions. A low-mileage EV owner may be best served by Charge Anytime Pay As You Go. A driver using close to 250 kWh each month and regularly charging publicly may obtain more value from Premium. A two-EV household may require Standard Plus or Premium Plus, but only when the combined vehicles use enough of the allowance. A customer wanting flexibility may prefer Simpler Energy. A household wanting twelve months of certainty may prefer 1 Year Fixed. A customer prioritising long-term certainty may select 2 Year Fixed, provided the £95-per-fuel exit charge does not create excessive risk. An existing solar owner supplied by OVO may qualify for SEG Beyond Exclusive. A customer retaining a specialist tariff with another supplier may accept OVO's lower standard SEG rate. A household buying solar and battery equipment from OVO may qualify for Install Exclusive, but the higher export payment must be assessed alongside the equipment purchase cost. The Octary OVO comparison engine should therefore complete four steps in order: 1. Establish eligibility 2. Build valid product combinations 3. Calculate household-specific net cost 4. Explain the recommendation and its limitations The cheapest advertised rate, the largest charging allowance and the highest export payment are not automatically the best options. The correct recommendation comes from modelling the household's energy supply, gas use, EV mileage, monthly charging pattern, public charging, solar generation, export, insurance needs and contract preferences as one connected system.
