Fuse Energy currently provides the lowest-priced tariff overall in this comparison. Its August 2026 Fixed (18m) V15 tariff costs £1,489 a year, making it £122 cheaper than EDF Energy's lowest-priced option. For EDF Energy, the cheapest available deal is its Standard (Variable) tariff, which costs £1,611 a year and operates without a fixed term.

Looking specifically at fixed contracts, Fuse Energy's pricing remains lower. Its £1,489 a year tariff requires an 18-month term and carries a £100 exit fee. In contrast, EDF Energy's most affordable fixed option—the Simply Fixed 2Yr Sep28v4 tariff—costs £1,691 a year. This requires a 24-month commitment and includes a £200 exit fee, resulting in a £202 annual price difference between the two suppliers' fixed deals.

For standard variable tariffs, pricing is effectively identical under typical usage assumptions. EDF Energy's variable tariff costs £1,611 a year, matching Fuse Energy's Variable Import tariff at £1,611 a year. Neither of these variable options requires a fixed term, and both avoid exit fees.

★ Winner: Fuse Energy

Fuse Energy is the stronger choice on fixed pricing and app ratings, while EDF Energy offers more established independent customer service data.

Based on the available data, Fuse Energy leads this comparison, primarily due to its lower fixed pricing.

Fuse Energy provides a fixed deal that costs less than EDF Energy's equivalents, alongside strong customer sentiment scores on Trustpilot. Because Fuse Energy lacks independent customer service data from Citizens Advice and Which?, this assessment relies more heavily on pricing and user-generated reviews.

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.
