EDF’s Green Energy Credentials
EDF generates more low carbon electricity than any other UK company through its nuclear fleet. It also operates wind farms and holds 100% REGO backed renewable electricity certificates for its green tariffs. This means EDF’s green credentials are stronger than most, backed by actual generation capacity, not just certificate buys. If you’re comparing green suppliers, also see our Compare Green Energy page for the full market picture.
EDF GoElectric Tariff for EV Owners
The GoElectric tariff offers EDF energy customers significantly cheaper overnight electricity for EV charging. If you own or are considering an electric vehicle, pairing an EV with an overnight charging tariff like GoElectric can dramatically reduce running costs, often to the equivalent of under 3p per mile. See our EV Chargers guide for more on home charging setup and the best EV tariffs available.

Is EDF Right for Your Household?
EDF scores reasonably well on customer service metrics, with a Citizens Advice rating that consistently places them in the upper half of large suppliers. Their app and online account management have been positively received, with reliable billing and meter reading submission. Call wait times can be longer than smaller digital first suppliers. EDF has been proactive on smart meter installation, their rollout programme is one of the more advanced among big six era suppliers, and smart meter customers report fewer billing issues than those still on traditional meters. EDF also participates in the Warm Home Discount scheme and has dedicated support teams for vulnerable customers.
EDF’s Customer Experience
EDF is unique among UK energy suppliers in owning and operating nuclear power stations, specifically the UK’s eight remaining active nuclear plants, which generate around 15% of Britain’s electricity. Nuclear power produces near zero carbon emissions at the point of generation, and EDF’s generation profile means their supplied electricity has one of the lowest carbon intensities of any major UK supplier. For customers who prioritise lo carbon electricity but are sceptical of purely certificate backed green tariffs, EDF’s direct ownership of low carbon generation makes their green offering more substantive than most. Their Go Electric tariff is designed for EV drivers, offering a cheap overnight rate for home charging alongside their standard supply.

Does EDF offer genuinely green energy?

-
What's EDF's GoElectric tariff?
GoElectric is EDF’s time of use tariff designed for electric vehicle owners. It offers a significantly cheaper overnight rate for charging, helping EV drivers minimise running costs. A smart meter is required. Visit our EV Chargers page for more on home charging setups and the best available overnight tariffs.
-
What happens if I want to leave my EDF fixed deal early?
EDF charges exit fees of £50–£75 per fuel on fixed tariffs. If you leave mid contract, calculate whether the savings from a better deal outweigh the fees. If EDF increases your price mid contract (beyond RPI), you may be entitled to exit without penalty, check your contract terms.
-
Does EDF supply business energy?
Yes. EDF is one of the UK’s major business energy suppliers. Business tariffs aren’t covered by the Ofgem price cap and are negotiated directly. See our Compare Business Energy page for an overview of the business energy market and how to find the best commercial rates.
-
How do EDF's electricity tariffs compare to other suppliers?
EDF’s electricity tariffs typically sit at or near the Ofgem price cap on variable deals, with fixed offers available slightly above or below depending on market conditions. They’re rarely the outright cheapest supplier on any given comparison, but they combine competitive pricing with above average customer service ratings, a combination that suits households who don’t want to switch again in 12 months. Use Switcheroo to compare EDF’s current live rates against all available deals.
-
What happens if I move house while on an EDF tariff?
EDF allows customers to transfer their existing tariff to a new address in most cases, subject to meter compatibility. If you’re moving out of a property, notify EDF at least 48 hours in advance with a final meter reading. EDF will close your account at the old address and, if requested, open one at the new address. If you’re buying a property with a different meter type or a different energy setup, you may need a new tariff. EDF’s customer team can advise on the specific steps for your circumstances.
