About EDF Energy and Fuse Energy
Who is EDF Energy?
Set up in 2002, EDF Energy is the British retail branch of the French state-owned Électricité de France and is one of the UK's largest domestic energy suppliers. The company focuses on generating its own zero-carbon electricity through its existing UK nuclear fleet and new-build projects such as Hinkley Point C, and offers a dedicated app to help customers manage their accounts.
Who are Fuse Energy?
Set up in 2022 by former Revolut employees, Fuse Energy is a newer, smaller supplier backed by investors such as Balderton Capital. It focuses on a tech-led approach, allowing customers to manage their accounts entirely through a smart app that includes an AI assistant, and it upgrades non-smart meters for free.

Fuse Energy offers a simple range of standard variable and fixed-term tariffs. It also provides off-peak options that give lower rates for the whole household during the night.
Customer reviews
EDF Energy and Fuse Energy both achieve a 4.8 out of 5 score on Trustpilot. Fuse Energy holds a higher proportion of five-star ratings at 91%, compared to 83% for EDF Energy. It is worth noting that EDF Energy's rating stems from a much larger volume of over 243,000 reviews, whereas Fuse Energy has approximately 8,800.
In written feedback, EDF Energy customers frequently mention polite staff and effective issue resolution. Fuse Energy reviewers similarly highlight helpful customer service and quick problem solving, although a portion note occasional initial delays when attempting to contact an agent.
EDF Energy achieves a score of 58 in the annual Which? customer satisfaction survey. It receives 9 out of 10 for helping those who need it, but records lower marks in other categories, including 2 out of 5 for customer service and 1 out of 5 for switching. Fuse Energy does not currently hold a Which? score.
App quality and features
Fuse Energy records higher scores across both major app stores, holding a 4.8 rating on the App Store and Google Play. In comparison, EDF Energy scores 4.6 on iOS and 4.4 on Android.
The two suppliers possess vastly different rating volumes. EDF Energy's scores are drawn from tens of thousands of ratings, whereas Fuse Energy has fewer than 1,000 ratings on each platform. Consequently, Fuse Energy's smaller sample size makes direct comparison with EDF Energy's established app difficult.
Both suppliers actively maintain their applications with recent updates. Recent iOS reviews for EDF Energy indicate notable improvements to the app, though some users report issues with the iPad display. Conversely, recent Fuse Energy reviews highlight the ability to chat with human agents directly through the interface.
Service and support
EDF Energy achieves 2.9 out of 5 in the latest Citizens Advice ratings, placing 11th overall. The supplier records an average call centre wait time of 2 minutes 46 seconds and responds to 85.6% of emails within two days. Additionally, EDF Energy maintains formal vulnerability commitments registered with Citizens Advice.
Fuse Energy does not currently feature in the Citizens Advice data. While this is common for newer or smaller suppliers, it prevents a direct comparison of the two companies using these independent service metrics.
Regarding payment methods, EDF Energy accepts Direct Debit, cash, cheque, and prepayment. Its telephone support operates Monday to Thursday from 8am to 6pm, and Friday from 8am to 4pm, remaining closed on weekends.
Complaints and performance
We only have complaints data for EDF Energy for the first quarter of 2025. Fuse Energy has not shared any complaints data, so we cannot compare the two suppliers directly.
Green Energy Comparison
EDF Energy
EDF Energy generates its own zero-carbon electricity, mainly through its nuclear power stations. According to Citizens Advice data from January to March 2026, the supplier's fuel mix is largely nuclear, with some fossil fuels and renewables. It backs its zero-carbon tariffs with nuclear power as standard, rather than relying solely on renewable energy certificates.[1]
Fuse Energy
Fuse Energy takes a different approach to clean energy. It does not buy renewable certificates to claim its tariffs are 100% green. Instead, it sells its certificates and reinvests the money into building its own clean energy infrastructure, such as solar and wind farms, and developing technologies like green hydrogen. It also encourages households to shift their energy use to off-peak times when demand is lower.[2]

Hi, I'm Rob, and I run Energy-Review.co.uk. I initially started this project in 2018 when I was looking to switch energy suppliers and found there wasn't a website that provided simple, data-backed reviews on all the suppliers available. Since then, I have spent a lot of time (too much, some may say!) looking at all publicly available data about each supplier and writing reviews using this information. These reviews are updated as regularly as possible, and any data is backed up by a source where necessary. I have also started writing guides on various energy-related topics, which hopefully you will find useful. If you find any issues, please use our contact form to let us know.
