Fix'd Dual 24M Explained

How Fix'd Dual 24M works

The tariff fixes four principal charges: The unit rate determines the charge for each kilowatt hour consumed. The standing charge is applied every day for each fuel, including days when little or no energy is used. Outfox's terms define a fixed tariff as one whose unit rates and standing charges do not increase or decrease during the tariff term. The monthly Direct Debit is not fixed because the payment must still reflect actual consumption, expected future use and the account balance. A household using more energy will therefore pay more even though the tariff prices remain unchanged.

• The electricity unit rate
• The electricity daily standing charge
• The gas unit rate
• The gas daily standing charge

The current tariff version

Outfox frequently releases new versions of its fixed tariffs as wholesale prices, network costs and market conditions change. The live July 2026 two-year product is listed as Fix'd Dual Jul26 24M v1. Earlier versions from May and June 2026 may still apply to existing customers, but they should not be assumed to have the same rates as the July offer. The product name identifies: Customers should retain the Tariff Information Label and welcome documents for the exact version they accept. These confirm the regional rates, standing charges, exit fees and tariff end date.

Regional pricing

Outfox does not charge one national electricity rate under this tariff. Electricity prices vary across Great Britain's distribution regions. A household in northern Scotland may therefore receive different rates from a comparable property in London, Yorkshire or southern England. The tariff must be compared using a postcode-level quotation. Current comparison records indicate that Fix'd Dual Jul26 24M v1 has different regional prices, and published national or representative figures should not be treated as a guaranteed personal offer. Standing charges also matter. A low-use household may be affected more heavily by a high daily standing charge because fixed charges form a greater proportion of its total bill. The annual calculation should use: Electricity kWh × electricity rate plus: 365 × electricity standing charge Gas should be calculated separately using the gas unit rate and standing charge.

Fixed prices do not mean a fixed bill

A common misunderstanding is that a fixed tariff guarantees the same monthly or annual payment. It does not. The price for each unit is fixed, but the number of units used can change. A cold winter, additional occupant, new electric vehicle or increased home working can raise consumption. Outfox's terms state that monthly Direct Debit payments are normally based on estimated annual consumption and can be reviewed when consumption information or account balances change. The supplier may also amend the payment after receiving industry consumption data that differs from the figure entered during sign-up. A customer could therefore see their Direct Debit increase during the fixed term without the tariff's unit rates changing.

Dual-fuel requirement

Fix'd Dual 24M is designed for customers who move both electricity and gas to Outfox. It should not be selected where the household wants Outfox to supply electricity only or gas only. Outfox lists separate electricity-only fixed tariffs for customers without mains gas or those wanting different suppliers for each fuel. Dual fuel can simplify account management because both fuels appear under the same supplier relationship. It is not automatically cheaper than selecting separate electricity and gas products. A proper comparison should assess:

• Outfox dual-fuel cost
• Outfox electricity-only cost plus another gas supplier
• Another supplier's complete dual-fuel offer
• Any loss of specialist EV or export benefits

Direct Debit and digital account management

Outfox's general terms make monthly Direct Debit in advance and online account management the normal requirements for its tariffs. Customers receive bills and account information electronically and are expected to manage meter readings, contact details and payment arrangements through the online account, email or web chat. The first payment may be collected soon after sign-up, before the first full monthly statement. Customers should check the payment date and opening amount rather than assuming it will be taken one month after the supply transfer. A customer unable to use digital account management should confirm whether Outfox can make an accessibility adjustment before joining.

Meter readings and smart meters

Fix'd Dual 24M is not an electric-vehicle or time-of-use tariff. Electricity is not automatically cheaper at night merely because the property has a smart meter. Where Outfox can communicate with a smart meter, readings may be collected automatically. If communication is unavailable, the meter continues functioning as a conventional meter and the customer may need to submit regular readings manually. Outfox's terms require customers to provide opening, closing and regular readings where needed. Missing readings can lead to estimated bills and later corrections. Households with Economy 7 or another multi-rate meter should inspect the tariff quotation carefully. They should not assume the 24-month fixed tariff includes a favourable overnight rate unless separate day and night rates are clearly shown.

The £100-per-fuel exit fee

The principal financial risk is the early exit charge. Current tariff records show a fee of £100 for electricity and £100 for gas. A customer switching both fuels away early could therefore be charged £200. This changes the economics of a future switch. Suppose a new tariff becomes available after one year and is expected to save £300 over the remaining twelve months. After subtracting £200 of exit fees, the effective saving falls to £100. If the alternative would save only £150, leaving early could make the customer £50 worse off. The comparison should use savings over the remaining contract period rather than the alternative supplier's complete headline annual estimate.

Cooling-off period

A customer can cancel during the fourteen-day cooling-off period without paying the tariff exit fees. They remain responsible for electricity and gas consumed while Outfox supplied the property, together with the corresponding standing charges. After the cooling-off period, leaving normally becomes an ordinary supplier switch and the tariff's exit conditions can apply. Customers should check their quotation, contract dates and meter details promptly rather than waiting until the cooling-off period has passed.

Leaving near the tariff end date

Outfox's terms state that fixed-tariff customers receive at least 49 days' notice before the tariff expires. A customer can normally switch without an early exit penalty where the new supplier's supply start date falls within the final 49 days of the fixed term. The renewal notice should provide: Customers should begin comparing alternatives during this period rather than allowing the tariff to expire without review.

• The tariff end date
• Renewal options
• The tariff the account will move onto if no action is taken
• Updated estimated annual costs

What happens when the 24 months end?

If the customer does not choose another tariff, the account can move onto Outfox's relevant standard variable product. Outfox confirms that customers approaching the end of a fixed term receive renewal information and can change supplier without an exit fee during the protected final period. The replacement variable tariff may have higher or lower rates than the expired fixed product. It will also lack the same two-year price guarantee. The household should compare the market again rather than assuming that remaining with the default renewal option is cheapest.

Protection from the July 2026 price cap

The Ofgem price cap rose by 13 per cent from 1 July 2026. The national average Direct Debit rates for capped variable tariffs became 26.11p per kWh for electricity and 7.33p per kWh for gas, with average daily standing charges of 57.19p and 29.04p respectively. Actual capped rates differ by region. An existing fixed-tariff customer is generally not moved onto these capped variable rates when the cap changes. The customer continues paying the rates agreed under the fixed contract. This is the main attraction of the two-year fix: protection against price-cap and market increases during both years.

What happens if prices fall?

The tariff does not normally become cheaper when the price cap or new fixed offers fall. A customer remains on the agreed rates unless they switch, change tariff under permitted terms or reach the contract end date. The £200 combined exit fee can make it expensive to respond to a falling market. For that reason, the tariff should be assessed using more than one future-price scenario: The two-year fix is strongest under the rising-price scenario and potentially weakest where prices fall substantially soon after sign-up.

• Prices rise significantly
• Prices remain broadly stable
• Prices fall during the first year
• Prices fall during the second year

Comparing the 24-month and 12-month fixes

The live July tariff range includes both Fix'd Dual Jul26 12M and Fix'd Dual Jul26 24M products. Current records show £75-per-fuel exit fees on the twelve-month version and £100 per fuel on the 24-month version. The twelve-month tariff offers: The 24-month tariff offers: The correct choice depends on the actual regional rates. A small price premium for the second year may be reasonable for a customer who strongly values certainty. A substantial premium could make the shorter fix more attractive.

• A shorter commitment
• Earlier opportunity to review the market
• Lower £150 combined exit exposure
• Less long-term price certainty
• Two years of fixed unit rates
• Protection across more price-cap periods
• Less need to renew after one year
• Higher £200 combined exit exposure

Comparing the tariff with the Price Cap Tracker

Outfox's Price Cap Tracker has a fixed contract period but variable prices linked to the Ofgem cap. The tracker can become cheaper when the cap falls, but it can also rise when the cap increases. The 24-month Fix'd tariff maintains its agreed unit rates and standing charges throughout the term. The tracker may appeal to someone expecting falling prices and willing to accept quarterly movements. Fix'd Dual 24M may appeal to someone expecting prices to remain high or rise and who wants predictable rates for two winters.

Who is most likely to benefit?

Outfox Fix'd Dual 24M may suit a household that: It may be less suitable for someone planning to move, install major energy technology or review suppliers frequently. A household expecting to add a heat pump, electric vehicle, solar panels or battery storage should consider how those changes could alter consumption and tariff requirements before committing for two years. Outfox Fix'd Dual 24M provides long-term protection from changing unit rates and standing charges. Its value depends on whether the July 2026 regional quotation remains competitive over both years and whether the customer can stay for the full term without needing to pay the substantial exit fees.

• Uses both electricity and mains gas
• Wants two years of rate certainty
• Pays by monthly Direct Debit
• Can manage the account online
• Expects to remain in the same property
• Is unlikely to switch suppliers during the term
• Accepts the potential £200 early exit charge
