OVO 1 Year Fixed is a conventional fixed-rate household energy tariff. It fixes the customer's electricity and gas unit rates and daily standing charges for twelve months, providing protection from ordinary market price increases during the contract. The tariff is available for electricity-only and dual-fuel households, subject to the products and prices offered for the customer's postcode. OVO currently applies an early exit fee of ยฃ50 for each fuel when a customer leaves before the protected renewal period. This guide was checked on 11 July 2026.
When a customer joins the tariff, OVO confirms a unit rate and standing charge for each fuel included in the contract. The unit rate is the price paid for each kilowatt hour of electricity or gas used. The standing charge is a fixed daily amount applied regardless of how much energy the household consumes. These prices normally remain fixed for twelve months from the tariff start date. OVO describes the product as a way to protect customers from future price changes and provide greater consistency when budgeting. The tariff does not guarantee a fixed monthly payment. A household that uses more electricity or gas will still pay more, even though the price charged for each unit remains unchanged. A cold winter, an electric vehicle, a heat pump or additional occupants can therefore increase the bill without any change to the tariff itself.
The word "fixed" can cause confusion. OVO fixes the tariff rates, but the monthly Direct Debit is an estimate designed to collect enough money to cover the household's expected annual cost. If the household uses more energy than forecast, OVO may increase the monthly payment. If consumption falls or the account develops a large credit balance, the payment may be reduced. The most reliable way to compare the tariff is therefore to use the annual electricity and gas consumption figures shown on a recent bill. The annual electricity calculation is: Annual electricity consumption multiplied by the electricity unit rate, plus 365 days of electricity standing charges. Gas should be calculated separately using the gas rate and gas standing charge. The proposed monthly Direct Debit is useful for budgeting, but it is not the tariff price.
OVO does not advertise one national 1 Year Fixed price for every household. The actual electricity rate and standing charge depend partly on the customer's distribution region. Gas prices, payment arrangements, meter type and whether the property has an Economy 7 or multi-rate meter can also affect the quotation. A household in northern Scotland may therefore receive different electricity prices from an otherwise similar household in London or southern England. The live quote should show: The electricity unit rate The electricity standing charge The gas unit rate, where applicable The gas standing charge The estimated annual cost The contract dates The exit fees Customers should retain the tariff summary or Tariff Information Label supplied when they join. It provides the evidence needed to compare the offer with OVO Simpler Energy and competing suppliers.
OVO currently lists an early exit fee of ยฃ50 for each fuel on its 1 Year Fixed tariff. An electricity-only customer could therefore face a ยฃ50 fee for leaving early. A dual-fuel customer could face two charges, producing a total potential exit cost of ยฃ100. The exit fee matters when calculating whether switching to a cheaper tariff is worthwhile. Suppose another tariff would save ยฃ120 during the remainder of the contract. A dual-fuel exit charge of ยฃ100 would reduce the effective benefit to only ยฃ20. A comparison should therefore calculate: Expected saving before the OVO contract ends, minus the applicable exit fees. The fee does not normally apply during the final renewal window. OVO states that customers can generally leave without an exit fee once they are within 53 days of the contract end date. It also says the fee is not charged during the new supplier's 14-day cooling-off period or when an eligible customer moves from one OVO fixed tariff to another OVO fixed product. The customer should still check the current contract because tariff versions and conditions can change.
A fixed tariff protects the customer from ordinary price rises affecting variable tariffs during the fixed period. OVO's Simpler Energy tariff can change in line with the Ofgem price cap. The current cap period runs from 1 July to 30 September 2026, and OVO confirms that the cap affects variable tariffs rather than customers already on ordinary fixed-rate products. If the price cap rises later in the year, a customer on 1 Year Fixed normally continues paying the agreed rates until the tariff ends. This is the main reason households choose a fixed product. It replaces some uncertainty with known rates. The financial value depends on the fixed price offered. A tariff fixed well below future variable rates could save money. A tariff fixed above future rates could cost more.
The disadvantage of fixing is that the customer does not automatically benefit when ordinary market or price-cap rates fall. Someone on Simpler Energy would normally receive the new capped rates when they take effect. A customer on 1 Year Fixed generally remains on the contracted prices. The customer could leave and change tariff, but the ยฃ50-per-fuel exit fee may reduce or remove the saving. This creates a trade-off. The household accepts the possibility of paying more if prices fall in exchange for protection against prices rising. A fixed tariff is therefore not automatically cheaper. It is partly a risk-management product.
Government changes can occasionally affect a fixed tariff even though its ordinary commercial rates are fixed. OVO reduced pay-monthly fixed tariff prices from 1 April 2026 to pass through reductions in government levy costs. OVO states that customers did not need to take action because the revised prices were applied automatically. This was an exceptional policy adjustment rather than the normal quarterly operation of a fixed tariff. Customers should therefore read any tariff communications from OVO rather than assuming that a fixed price can never change under any circumstances.
OVO 1 Year Fixed is compatible with Charge Anytime. Charge Anytime is an electric vehicle charging addition. It does not replace the household tariff. Ordinary household electricity continues to be charged using the 1 Year Fixed rate. Qualifying smart EV charging is then treated under the selected Charge Anytime arrangement. The pay-as-you-go option currently discounts qualifying managed EV charging to 14 pence per kilowatt hour. OVO also offers monthly plans with home charging mileage allowances, public charging vouchers and additional benefits. This can make the tariff relevant to an electric vehicle owner even though it does not contain a conventional cheap overnight electricity period. The reduction applies only to qualifying smart vehicle charging. Other overnight electricity, such as a home battery, immersion heater or dishwasher, remains charged at the fixed household rate. A customer should therefore compare the combined annual cost of 1 Year Fixed and Charge Anytime with tariffs that discount all household electricity during an overnight window.
Charge Anytime requires an OVO energy account, a compatible smart meter and a compatible electric vehicle or charger. OVO manages charging through its Charge app and schedules the vehicle within the time chosen by the driver. The customer can override the smart schedule when an immediate charge is needed, but override or boost charging is charged at the ordinary home tariff rate rather than receiving the managed charging benefit. This distinction should be included in any EV cost estimate. A driver who regularly needs immediate charging may pay more than someone able to leave the vehicle connected for several hours.
The standard 1 Year Fixed tariff allows OVO's Greener Electricity upgrade to be added separately. Boiler cover is also available as a separate product. These additions should not be confused with the separate bundled tariffs. OVO also markets: 1 Year Fixed Plus Boiler Cover 1 Year Fixed Plus Greener Electricity The standard tariff may suit someone who wants fixed energy prices but prefers to choose insurance or renewable electricity upgrades independently. The bundled versions may use different standing charges, discounts or product conditions. They should therefore be compared using their complete annual cost rather than assuming that the underlying energy rates are identical.
A smart meter can improve billing accuracy and provide detailed information about when electricity is used. It is particularly useful for customers considering Charge Anytime, solar export, battery storage or future time-based products. A customer without a working smart connection may still be able to join the basic fixed tariff, depending on OVO's live eligibility requirements, but would not be able to use services that depend on automated smart readings. Traditional meter customers should submit regular readings to prevent bills being based on estimates.
Simpler Energy is OVO's standard variable tariff. Its rates can change with the Ofgem price cap, but it has no fixed contract term and no exit fee. OVO 1 Year Fixed protects the unit rates and standing charges for twelve months but introduces a ยฃ50 exit fee for each fuel. The best choice depends on: The difference between the quoted fixed and variable rates Expected price-cap changes Annual consumption The likelihood of moving home The possibility of switching supplier The value placed on price certainty A high-consumption household may benefit more from a small reduction in the unit rate because that reduction applies to many kilowatt hours. A very low-consumption household may be more affected by differences in standing charges.
OVO also offers a 2 Year Fixed tariff. The two-year product gives a longer period of price certainty, but OVO currently lists a higher exit fee of ยฃ95 for each fuel. The one-year tariff may suit someone who wants protection without making a two-year commitment. The two-year option may appeal to a household expecting prices to rise over a longer period and unlikely to change supplier or move home. Neither option is guaranteed to be cheaper than future variable tariffs.
OVO 1 Year Fixed may suit a household that wants predictable rates for the next twelve months and expects to remain with OVO throughout the contract. It may be particularly appropriate where the quoted price is competitive with Simpler Energy and the customer is concerned about future price increases. It can also suit an EV owner who qualifies for Charge Anytime and wants fixed ordinary household rates alongside managed vehicle charging. The tariff may be less suitable for someone likely to move, change supplier or install technology that could make another tariff more attractive during the year. It may also be less suitable for customers who expect energy prices to fall and want immediate access to lower variable rates. OVO 1 Year Fixed provides straightforward protection from normal energy price movements. Its value depends on the quoted regional rates, the household's consumption and whether the customer remains long enough to avoid the early exit fees.
