EDF Energy Review (September 2026)

Overview

Who are EDF Energy?

EDF Energy was formed in 2002 and is the UK retail branch of the French state-owned EDF Group. It has operated in the UK for decades and is one of the country's biggest domestic energy suppliers.

What sets the supplier apart is its focus on generating its own zero-carbon electricity, largely through its UK nuclear power stations. It is also building large-scale infrastructure projects, such as the Hinkley Point C nuclear plant. The supplier offers a wide product range, including standard variable and fixed-rate tariffs, as well as specialist deals for electric vehicle owners, heat pump users, and households with solar panels. In the 2025 Uswitch Energy Awards, EDF Energy won Silver for Overall Customer Satisfaction and Silver for Customer Service.

Prices

EDF Energy's lowest-priced option is the Standard (Variable) tariff, estimated at £1,611 annually. Because it has no fixed term, it carries a £0 exit fee, allowing households to switch suppliers without incurring a penalty.

For those seeking stable unit rates, the most affordable fixed deal is the Simply Fixed 2Yr Sep28v4 tariff at £1,691 per year. This requires a 24-month commitment and includes a £200 exit fee if the contract is terminated early.

Tariff details

EDF Energy offers a range of mainstream and specialist tariffs for domestic customers. Its fixed-rate deals are available with terms from 12 to 24 months.

Customer Reviews

EDF Energy maintains a Trustpilot rating of 4.8 out of 5 across 251,360 reviews. The data shows a net-positive score of 82%, with 83% of users awarding five stars and 7% leaving one star. The supplier replies to 99% of negative feedback, usually within 24 hours.

Trustpilot feedback frequently mentions polite staff and prompt problem resolution regarding tariff guidance. Conversely, a portion of the negative reviews cite difficulties navigating the automated phone systems and reaching representatives.

In the annual Which? energy survey, EDF Energy achieved an overall score of 58. Sub-scores include 9 out of 10 for helping those who need it, alongside ratings of 2 out of 5 for both customer service and value for money. The supplier recorded 7 out of 15 for complaints handling, 5 out of 10 for smart meters, and 1 out of 5 for the switching process.

App Experience

EDF Energy offers mobile apps for Apple and Android devices to help customers manage accounts and submit meter readings. The iOS version holds a score of 4.6 out of 5 from 187,000 ratings. On the Google Play Store, the app scores 4.3 out of 5 across 51,073 ratings, with a net-positive score of 74.6% and over one million installs.

Both versions of the application receive regular maintenance; the iOS app shows three updates in the last 90 days, while the Android version was updated 14 days ago. Release notes indicate recent changes include new methods for viewing tariff offers and general fixes for account displays.

A recent sample of iOS feedback indicates an average of 2.3 stars, although this draws from a limited number of reviews. Within this subset, some users note the updated design is useful for managing bills, while others report technical issues when submitting payments or locating updated balances after entering meter readings.

Service & Support

In the latest Citizens Advice rankings, EDF Energy scored 2.9 out of 5, placing it 11th among UK suppliers. According to this data, the company receives 47.6 complaints per 10,000 customers.

For telephone support, the average call centre wait time is 2 minutes 46 seconds. When contacted via email, EDF Energy responds to 85.6% of messages within two days.

Customer service lines operate from 8am to 6pm Monday through Thursday, and 8am to 4pm on Fridays, remaining closed on weekends. Accepted payment methods include Direct Debit, cash, cheque, and prepayment.

EDF Energy complaints and performance

The complaint figures below use the reporting period stated in the supplied data.

Green Energy

EDF Energy is Britain's biggest generator of zero-carbon electricity. While many suppliers rely on buying Renewable Energy Guarantees of Origin (REGO) certificates to match their customers' use, EDF generates a massive amount of zero-carbon power directly. It operates a large fleet of nuclear power stations, alongside 37 wind farms, six solar sites, and five battery storage facilities.^[1][2][3]

According to Citizens Advice data from early 2026, EDF Energy's electricity fuel mix is largely nuclear, with some fossil fuel and renewables. The supplier does not currently offer a dedicated mainstream green tariff, but its specialist EV tariffs are backed by 100% zero-carbon nuclear electricity as standard. EDF Group is investing heavily in expanding its nuclear, wind, and solar capacity to help the UK reach its net zero targets.^[4][5]
