EDF Simply Fixed is a conventional fixed price energy tariff for households that want protection from changes in electricity and gas prices. The unit rates and daily standing charges shown when the customer joins remain fixed until the tariff's stated end date. This can make household budgeting easier, particularly when energy markets are uncertain. It does not fix the total bill, because the customer still pays for every unit consumed. This guide was checked on 11 July 2026.
A customer joining Simply Fixed agrees to pay specified electricity and gas unit rates for a defined period. The daily standing charges are also secured for the same period. If wholesale energy costs rise or the Ofgem price cap increases, the contracted rates normally remain unchanged. If market prices fall, the customer continues paying the agreed rates until the tariff ends or they leave early. EDF describes its fixed products as providing price stability, protection from sudden increases and more predictable budgeting. The company currently markets Simply Fixed to both dual fuel and electricity only households. ([edfenergy.com](https://www.edfenergy.com/gas-and-electricity/fixed-price-energy)) The tariff may be offered for one year, two years or another stated period. EDF has launched several versions over time, each carrying its own name, end date, prices and exit conditions. Customers should therefore treat the tariff information label supplied with their quotation as the definitive document. An older Simply Fixed article or price table may describe a different version that is no longer available.
EDF does not publish one universal Simply Fixed price for every household. Electricity rates vary between distribution regions, while gas prices, payment method and meter configuration can also affect the quotation. A household in northern Scotland may receive different electricity rates from one in London, southern England or Wales. Economy 7 customers may also receive separate day and night prices rather than a single electricity rate. EDF requires prospective customers to enter their postcode and energy details to view the available tariffs and exact rates. Existing customers can obtain personalised offers through MyAccount or the EDF app. ([edfenergy.com](https://www.edfenergy.com/tariff-information-labels)) The live quotation should show: The electricity unit rate The gas unit rate, where applicable The electricity standing charge The gas standing charge The tariff end date The exit fee for each fuel The payment method Whether the tariff is electricity only or dual fuel The exact rates matter more than a national annual estimate. Two tariffs can produce the same advertised annual figure for a typical household while producing different results for someone with unusually high electricity or gas consumption.
From 1 July to 30 September 2026, the average Ofgem price cap rate for a Direct Debit customer is 26.11 pence per kilowatt hour for electricity and 7.33 pence per kilowatt hour for gas. The average daily standing charges are 57.19 pence for electricity and 29.04 pence for gas. These figures include VAT and represent averages across England, Scotland and Wales. ([ofgem.gov.uk](https://www.ofgem.gov.uk/information-consumers/energy-advice-households/energy-price-cap-unit-rates-and-standing-charges)) The price cap does not apply directly to Simply Fixed. It protects customers on standard variable and default tariffs, while fixed tariff rates are determined by the contract accepted when the customer joins. This distinction can work in either direction. If the price cap rises in October 2026, a customer on Simply Fixed keeps the agreed rates. If the cap falls substantially, the fixed customer does not automatically receive that reduction. EDF's price forecasting page states that a one year fixed tariff costing ยฃ1,691 or less for the newly defined typical household could be cheaper than remaining on a price cap linked tariff over the forecast period. This is a forecast rather than a guarantee, and the calculation uses national average consumption rather than the customer's own use. ([edfenergy.com](https://www.edfenergy.com/gas-and-electricity/price-cap-predictions))
One of the most common misunderstandings is that joining a fixed tariff creates a fixed monthly energy bill. The tariff fixes the price of each unit. It does not fix the number of units consumed. A household that uses more electricity during a cold winter, charges an electric vehicle more often or increases electric heating will pay more. A household that reduces consumption will pay less. The standing charge is also added every day, even when no energy is used. A customer away from home for several weeks may consume very little electricity or gas but will continue accumulating standing charges. The monthly Direct Debit is a payment arrangement based on expected annual consumption and the account balance. EDF may increase or reduce it if actual meter readings show that the original estimate is inaccurate. Customers should therefore judge the tariff using annual unit rates and standing charges rather than comparing monthly Direct Debit suggestions alone.
EDF states that exit fees apply to Simply Fixed, but the amount depends on the individual tariff version. The fee should be displayed in the tariff information label before the customer agrees to switch. ([edfenergy.com](https://www.edfenergy.com/gas-and-electricity/fixed-price-energy)) Recent EDF fixed products demonstrate why checking the exact version matters. A two year Simply Fixed offer launched in March 2026 carried an exit fee of ยฃ75 per fuel. Other previous Simply Fixed versions have had ยฃ50 exit fees or, in some cases, no exit fee when purchased through a particular route. ([edfenergy.com](https://www.edfenergy.com/media-centre/edf-reduces-its-fixed-prices-with-new-tariff-matching-april-price-cap)) A dual fuel customer could face separate charges for leaving electricity and gas. If the fee were ยฃ75 per fuel, ending both supplies early could cost ยฃ150. This should be considered by customers planning to move home, install a heat pump, purchase an electric car or add solar panels and battery storage. A specialist tariff might later become more suitable, but the exit fee could reduce the benefit of changing. EDF explains that an exit fee may apply when a customer leaves 49 days or more before the tariff end date. Customers entering the final 49 day switching period can normally move without paying the early exit fee. ([edfenergy.com](https://www.edfenergy.com/help-support/faq/when-do-i-pay-early-exit-fee))
Simply Fixed and Simply Tracker may look similar because both have a stated end date, but their pricing behaves differently. Simply Fixed secures the unit rates and standing charges. Ordinary quarterly price cap changes do not alter them. Simply Tracker follows EDF Standard Variable prices when the Ofgem cap changes. Its main saving is delivered through discounted standing charges. A customer who expects price capped rates to fall may prefer the tracker because reductions can pass through every three months. Someone concerned about future increases may prefer the certainty of Simply Fixed. The decision also depends on exit fees, contract duration and the rates offered for the property.
A smart meter is not always required simply to join a conventional EDF fixed tariff. EDF may arrange installation at no additional cost where the household does not already have one. ([edfenergy.com](https://www.edfenergy.com/gas-and-electricity/electricity-only-tariffs)) A compatible smart meter can provide more accurate bills and may allow the household to participate in EDF Sunday Saver challenges. Sunday Saver rewards eligible customers for reducing electricity consumption during selected weekday peak periods. The reward may be used as free electricity during a later Sunday period. The programme is not a permanent guaranteed tariff rate. EDF states that challenges may not run every month, customers must join each available event and the amount of free electricity can change. Eligibility requires a smart meter sending EDF readings every thirty minutes. EDF says participating households may earn up to 16 hours of free electricity during a challenge week, depending on the current rules. ([edfenergy.com](https://www.edfenergy.com/gas-and-electricity/fixed-price-energy)) Sunday Saver should be regarded as a possible additional benefit rather than included as guaranteed annual savings.
The tariff may suit households that value certainty and want protection against price increases. It can be useful for families with predictable electricity and gas use, people managing a strict household budget and customers who prefer not to monitor changing wholesale or time based prices. Simply Fixed also requires less active management than FreePhase. Electricity is normally charged at the same rate throughout the day, unless the property has a multi rate meter, so the customer does not have to move consumption away from the evening peak. It may also suit people who expect to remain in the same property and on the same energy arrangement for the full contract term.
Electric vehicle owners should compare Simply Fixed with EDF GoElectric or Pod Point Plug and Power. A cheap overnight charging rate may create greater savings than a standard fixed tariff. Heat pump households should examine EDF Heat Pump Tracker, which provides discounted electricity during two daily periods. Solar and battery owners may obtain greater value from EDF Empower Fixed and an eligible export tariff. Homes able to shift substantial electricity use away from 4pm to 7pm should compare FreePhase. Its time based prices can reward flexible consumption, although it also creates more exposure to expensive peak periods. Simply Fixed provides no special night rate, heat pump discount or solar export payment. Its value comes from price certainty rather than household technology optimisation.
The most reliable comparison uses the household's actual annual electricity and gas consumption. Multiply electricity use by the quoted electricity rate, then add 365 days of electricity standing charges. Repeat the calculation for gas. Compare the result with EDF Standard Variable, Simply Tracker and any specialist tariff suited to the property. Add any exit fee owed to the current supplier and consider the cost of leaving Simply Fixed early if circumstances change. The calculation should use the exact postcode quotation and not an old national headline figure. EDF Simply Fixed offers understandable pricing and protection from future increases. Whether it represents good value depends on the rates offered, the contract length, the exit fees, expected consumption and the household's likelihood of needing a more specialised tariff before the fixed period ends.
