The short answer
Who EDF Simply Fixed is most likely to work for
Fixing buys rate certainty, not a fixed bill: unit rates and standing charges stay put while the amount you use can still change. If predictable rates matter more than following future capped prices, Simply Fixed does that job for the fuels in your quote.
Be honest about the trade. You are taking a view on where prices go, you are paying an exit fee per fuel to change your mind, and you are giving up the savings a time-of-use tariff could offer if you can shift usage. None of those makes it a bad tariff — they just make it a choice rather than a default.
Simply Fixed locks both the unit rate and the standing charge for the length of the deal. When the price cap moves, your prices do not — which is the whole point, and equally the whole risk.
EDF’s fixed offers can open, close and change. The product and regional figures on this page come from the currently available catalogue entry selected by the site; any other current variants are listed separately when the feed supplies them.
In its favour
- Unit rate and standing charge held for the whole term
- Protection if the price cap rises
- No smart meter or equipment required
- Available for electricity and gas together
Against it
- No benefit if the price cap falls
- Exit fee charged per fuel
- No reward for using electricity at cheaper times
- Rolls onto the standard variable tariff at the end unless you act
How it works
How EDF Simply Fixed sets its prices
You agree a unit rate and a standing charge, and they hold until the end date whatever the price cap does. Fixing does not fix your bill — use more and you pay more — it fixes the price of each unit.
Fixed deals are priced from what the market expects energy to cost over the term, not from today’s cap. That is why a fix can sit below the cap when the market expects prices to fall, and above it when the market expects a rise.
There is an exit fee, charged per fuel. A dual-fuel household leaving early pays it twice, which is worth knowing before treating the deal as reversible.
When the deal ends you move onto the standard variable tariff automatically unless you choose something else, so the end date is a date worth putting in a calendar.
Things to watch
The main trade-offs
Fixing is a bet in both directions. If the cap falls below your fixed rate you pay more than you would have, for as long as the deal runs.
The exit fee is per fuel, so leaving a dual-fuel fix early costs double.
Compare the standing charge as well as the unit rate. A low unit rate paired with a high daily charge can be worse for a light user than the reverse.
Do not substitute a similarly named fixed deal for the exact product shown. Terms, exit fees and regional rates can differ between variants.

Household fit
Who EDF Simply Fixed might be good for
The right answer depends on your equipment, routine and tolerance for changing prices—not just how much electricity you use.
Likely to suit
- Households that value a predictable bill over the chance of a lower one
- Anyone who expects energy prices to rise over the next year or two
- Budgeting households who want to know what a unit costs for the whole term
- People with no smart meter, for whom most smart tariffs are unavailable anyway
Less likely to suit
- Anyone who expects the price cap to fall and would rather follow it down
- Households that might move or change supplier during the term, given the exit fee
- People who could save more by shifting usage to cheap hours on a time-of-use tariff
- Anyone who would find the end date easy to forget — the rollover is onto the standard variable tariff
Before switching
Check the requirements and what will affect the result
What you need
- No smart meter or equipment needed
- Available for electricity, gas or both
- Exit fees apply, charged per fuel
- Deals open and close frequently — what is available today may not be tomorrow
What drives what you pay
- The rate you fixed at, which is settled the day you sign and cannot then move
- How much you use, the only variable left once the price is fixed
- What the price cap does over the term, which decides whether fixing turned out to be worth it
- Your region and payment method, both of which change the price you are offered
Match the tariff to your home
Your largest electrical loads can change the answer
A specialist tariff can be better aligned with one large device, but its eligibility and expensive periods still matter. These are comparisons to make, not automatic recommendations.
If you have an EV
An EV tariff may be simpler if most of your flexible electricity is car charging. Intelligent Octopus Go schedules compatible cars or chargers; Octopus Go and EDF Go Electric use fixed overnight windows.
If you have solar without a battery
The import tariff and the rate paid for exported electricity are separate decisions. A straightforward export tariff can be more useful than a peak-weighted battery tariff when generation is exported as it happens.
If you have solar and a home battery
A paired import/export tariff may fit better because a battery can charge in a cheap period and discharge or export in a more valuable one. The gross rate spread is not the same as profit after losses and degradation.
If you have a heat pump
A heat-pump tariff may align its cheaper periods with space and hot-water heating. Whether it wins depends on insulation, controls and how much heat can move away from expensive periods.
Alternatives
Other smart tariffs from Octopus and EDF to compare
These are other smart-tariff comparisons from the two suppliers, not a claim that every option suits the same household.
EDF Standard Variable
The decision this tariff exists to answer. Standard Variable can move with the cap and has no exit fee; Simply Fixed holds its rates for the term and may charge you to leave. The live regional annual estimates show which starts cheaper, while future price-cap movements remain unknown.
Review EDF Standard VariableEDF Simply Tracker
Simply Tracker follows EDF’s Standard Variable basis and discounts its standing charge for the stated term; Simply Fixed holds both unit rates and standing charges. Compare the exact live products and exit fees, because neither name alone establishes the lower total cost.

Directly comparable, and worth comparing on the day. Fixed tariffs are the one part of the market where suppliers compete on a single number, so the ranking changes week to week and neither supplier is reliably ahead.

Frequently asked questions
Does fixing fix my monthly bill?
No. It fixes the price of each unit and the daily standing charge. Use more and you still pay more — what cannot change is the rate you are charged.
What happens when the deal ends?
You move onto EDF’s standard variable tariff, which is priced at the Ofgem cap, unless you choose another tariff first. It is worth setting a reminder a month or so before the end date.
How much is the exit fee?
It varies by deal and is charged per fuel, so a dual-fuel household pays it twice. Check the figure for the specific deal before you commit — it is the difference between a decision you can reverse and one you cannot.
Is fixing cheaper than the price cap right now?
It depends on the exact product, region, payment method and consumption. The comparison card above shows how the current deal on this page sits against the cap figures available for your region today.
