Who are EDF Energy?
EDF Energy (owned by Électricité de France) supplies gas and electricity across Great Britain and invests heavily in low-carbon generation, including the new Hinkley Point C nuclear power station now under construction. EDF also provides EV charging solutions, smart-meter services and an established mobile app for account management (see “Website & App”).
The company markets itself as Britain’s biggest generator of zero-carbon electricity (nuclear + renewables).
What tariffs do EDF Energy offer?
EDF’s consumer range typically includes:
- Standard Variable — tracks the Ofgem price cap; no exit fees.
- Simply Tracker — tracks the cap with a £50 annual standing-charge discount (£25 per fuel); exit fees apply. (Price changes align to cap dates.)
- Fixed options (e.g., Simply Fixed Aug26 v9, Simply Fixed 2Yr Jul27) — lock unit rates and standing charges for 12–24 months; exit fees apply.
Switching speed: EDF says a switch completes within five working days (after any cooling-off). EDF also states switching is backed by the Energy Switch Guarantee.
How do EDF Energy compare on price?
EDF is rarely the absolute cheapest, but its Simply Tracker can undercut the cap via a standing-charge discount that benefits both low- and higher-usage households. Our latest quotes show Standard Variable and Simply Fixed are close in monthly cost at typical usage, with the tracker the cheapest of the three in this snapshot.

What do other EDF Energy reviews say?
Independent assessments place EDF in the middle of the pack overall, though with several strengths. Citizens Advice rates EDF at 2.7 out of 5 for January–March 2025, ranking the company 13th out of all suppliers. The breakdown shows 2/5 for complaint handling, 3/5 for call waiting times, and an impressive 5/5 for customer commitments.
Citizens Advice also reports that EDF receives 38.4 complaints per 10,000 customers, has an average call wait time of four minutes and 52 seconds, and answers 80.3% of emails within two working days.
In the Which? Energy Survey 2025, EDF performs better relative to other large, long-established brands. Which? places EDF alongside E.ON Next as the joint-highest ranked of the big suppliers, with an overall customer score of 62%. While smaller providers tend to dominate the very top of the table, this result puts EDF ahead of several other legacy names, showing it can still compete on service and reliability.
Public review scores are particularly strong. Trustpilot rates EDF at 4.8 out of 5 from more than 159,000 reviews, with many customers praising friendly, helpful agents and quick issue resolution. While there are the usual complaints you’d expect at scale, especially around smart meter installations, the balance of reviews is overwhelmingly positive.
The company’s mobile app is also highly rated. On the Apple App Store (UK), the “EDF UK” app has a 4.6 out of 5 rating from around 157,000 reviews. On Google Play, the “EDF” app is rated 4.8 out of 5 from over 38,000 reviews and has more than one million downloads, reflecting its widespread adoption and strong performance.
How green is EDF Energy’s energy?
EDF markets itself as Britain’s biggest generator of zero-carbon electricity, a position it achieves through its extensive nuclear fleet supplemented by renewable assets such as wind and solar farms. This focus on low-carbon generation means its overall carbon intensity is significantly lower than the UK average.
Fuel-mix percentages can vary slightly from year to year and between tariffs, so it’s always best to check EDF’s latest disclosure. As of the most recent Citizens Advice figures, EDF’s mix is 54% nuclear, 20% renewable, 24% fossil fuels and 2% other. For the full, up-to-date breakdown, see EDF’s own Fuel Mix page.
EDF is also investing heavily in future zero-carbon generation. Construction continues at Hinkley Point C in Somerset — the UK’s first new nuclear power station in decades. A key milestone was reached in July 2025, when the dome was successfully lifted onto the second reactor building.
What is EDF Energy’s customer service like?
EDF’s phone lines are open Monday to Thursday from 8am to 6pm, and Friday from 8am to 4pm. Outside of these hours, customers can use the app or online help for many tasks, and there is dedicated Saturday support for prepayment customers, as noted by Citizens Advice.
The company states that switches are completed within five working days after the cooling-off period, in line with Ofgem’s faster-switching rules.
From an independent perspective, Citizens Advice reports an average call wait time of four minutes and 52 seconds and 38.4 complaints per 10,000 customers for January–March 2025. In contrast, public sentiment on Trustpilot is far more favourable, with a 4.8 out of 5 score from over 159,000 reviews.
What is EDF Energy’s website/app like?
EDF offers online account management via its MyAccount portal and a dedicated mobile app. Both options allow customers to view bills, make payments, submit meter readings, manage tariffs and, for smart prepayment users, top up their balance.
The EDF app includes features such as auto-top-up, low-balance alerts, and access to the Energy Hub, which provides detailed usage data and tips for improving efficiency. On the Apple App Store, it holds a 4.6 out of 5 rating from around 157,000 reviews, while on Google Play it scores 4.8 out of 5 from over 38,000 reviews and has been downloaded more than a million times.
Do EDF Energy offer smart meters?
EDF is actively rolling out smart meters to its customers. These meters allow households to track energy use in near real-time and unlock additional features in the EDF app, such as detailed consumption breakdowns in the Energy Hub.
For smart prepayment customers, the meters enable in-app balance checks and top-ups, eliminating the need for a physical key or card. Smart meters also support EDF’s efforts to offer more tailored energy advice and improve billing accuracy.
Below are a few quick questions you may need answers to, along with our EDF Energy review:
Do they work with pre-payment meters?
Yes. EDF supports both traditional and smart prepayment meters. Prepayment customers do not receive monthly or quarterly bills, but they are sent an annual statement showing total energy use for the year. Those with a smart prepayment meter can top up online or through the EDF app, set up auto-top-ups, and receive low-balance alerts, removing the need to visit a shop.
Do they accept Economy 7?
EDF Energy accept Economy 7 provided the customer has a meter that supports Economy 7 billing.
Are they signed up to the Warm Home Discount?
EDF Energy are signed up to the Warm Home Discount. Eligible customers can apply at the EDF Energy website.
Are they signed up to the Energy Switch Guarantee?
Yes. EDF is signed up to the Energy Switch Guarantee, which means it commits to making the switching process simple and reliable. Under Ofgem’s faster-switching rules, EDF states that most switches are completed within five working days after the cooling-off period, significantly faster than the old 21-day standard.

Having been an EDF customer for a long time I noticed changes in recent years that are not customer friendly. But the biggest, most important change is EDF and their reluctance to re-pay credit. I followed the procedure (requesting money re-paid. listing up to date, accurate meter readings) one month later all I have is excuses but no money. I have written to their head office plus two other EDF addresses…nothing! I am over £500 in credit and as a pensioner on basic pension ( no triple lock increase) that money is needed. Do EDF care? Not at all. from Ken Turton
How is Nuclear Power not green?
Service is bad. Engineer never turns up been waiting 17 hours and nothing !! Called 3 time’s
I am an EDF customer, and have been for a few years now, and have been very happy with the company, my bills have been exceptionally low, my tariff is up on the 30th November, but trying to get a fixed deal for a year isn’t good , they have a fixed deal for 3 years, which is very expensive , my monthly payments going from £74 to £150 a month if this. Is capped it should be 12% it is now around 30% is this fair, I don’t think so, and they haven’t been very helpful, as a loyal customer , it is take it or leave it, hopefully I can get a better deal else where
