EDF doesn't set one flat price - your bill is built from a standing charge plus unit rates, shaped by the Ofgem price cap and the tariff you choose.
EDF is one of the larger domestic energy suppliers in the Great Britain market, and like all suppliers its standard variable prices are governed by the Ofgem price cap rather than set freely. What you actually pay depends on your tariff type, your region, your meter and how much gas and electricity you use. Understanding the mechanics - standing charges, unit rates and fixed-versus-variable deals - matters more than any single headline figure, because the cap is reviewed every three months.
| What you're buying | Typical price | How EDF Energy compares |
|---|---|---|
| Standard variable tariff (electricity unit rate) | Capped per kWh by Ofgem | Moves with the price cap each quarter; the per-unit pence figure is set within that ceiling. |
| Standard variable tariff (gas unit rate) | Capped per kWh by Ofgem | Lower per-unit than electricity, but usage is far higher in winter. |
| Daily standing charge (per fuel) | Fixed daily pence, varies by region | Charged whether or not you use any energy; differs between electricity and gas. |
| Fixed-rate tariff | Rates locked for the contract term | Can sit above or below the cap depending on wholesale conditions when you fix. |
| Economy 7 / time-of-use | Split day and night unit rates | Cheaper overnight units; only worth it if you shift enough usage to off-peak. |
| Estimated annual bill (typical-use household) | Quoted as an illustrative annual figure | A modelled estimate at typical consumption - your real bill depends on actual usage. |
Your EDF bill is built from two parts per fuel: a daily standing charge you pay regardless of usage, and a unit rate charged for every kilowatt-hour you use. For standard variable tariffs both are constrained by the Ofgem price cap, which is reviewed quarterly and varies slightly by region and payment method. Paying by monthly direct debit is usually the cheapest payment route, with prepayment and on-receipt-of-bill methods often costing a little more.
Fixed-rate tariffs work differently: they lock your unit rates and standing charges for a set term, which protects you if the cap rises but can leave you paying more if it falls. Whether a fix is good value depends entirely on where wholesale prices are heading when you sign up, which no one can predict with certainty.
For most homes the unit rates do the heavy lifting on the bill, especially gas usage through winter, but standing charges are a fixed floor you pay even in an empty property. Low-usage households feel standing charges more keenly as a share of the total, while high-usage homes are driven more by unit rates. This is general information about how energy pricing is structured, not personalised advice - your own best option depends on your usage, meter and circumstances, and comparing accredited switching services is the sensible way to check.
The most reliable lever on any energy bill is using less, since the unit-rate portion is usually the largest part of the cost - insulation, draught-proofing, heating controls and efficient appliances all reduce consumption. Submitting regular meter readings, or relying on a smart meter, keeps bills based on real usage rather than estimates that can overshoot.
On the tariff side, paying by monthly direct debit is generally the cheapest payment route, and it is worth periodically comparing your current annual cost against fixed and variable deals through an Ofgem-accredited service. If you are struggling with costs, EDF and other suppliers run hardship and warm-home schemes that some households may be eligible for.

Compare Pricing Now - It's FreeStandard variable prices are limited by the Ofgem energy price cap, which sets a ceiling on unit rates and standing charges and is reviewed every three months. Your exact rates also depend on your region, meter type and payment method.
It depends on where wholesale energy prices go. A fix protects you if the cap rises but can cost more if it falls, so neither is reliably cheaper - it is a trade-off between certainty and flexibility.
It is a fixed daily amount per fuel that you pay regardless of how much energy you use, covering network and supply costs. It varies by region and is separate from the per-unit rate for the energy itself.
Bills can change when the Ofgem price cap is updated each quarter, when you move on or off a fixed deal, or when seasonal usage shifts. Estimated readings can also cause swings that correct once an actual reading is submitted.
Possibly, but it depends on your usage and the deals available at the time. Comparing your current annual cost against other suppliers on an accredited comparison site is the way to check - this is general guidance, not personalised advice.
Because most standard tariffs sit close to the price cap, headline differences between large suppliers are often small. Service, fixed-deal pricing and any perks can vary, so it is worth comparing total annual cost rather than a single rate.
