Fuse Energy Review (August 2026)

Overview
Fuse Energy offers strong app-based account management and high customer review scores, though it lacks independent service data from Citizens Advice.
Who are Fuse Energy?
Fuse Energy is one of the UK's newest domestic energy suppliers. Former Revolut executives Alan Chang and Charles Orr set up the company in 2022, and it launched to the public in 2023. The supplier makes its own power, runs its own energy trading desk, and supplies electricity and gas to households. It has raised hundreds of millions of pounds in funding from investors to support its growth.
What sets Fuse Energy apart is its app-first approach. Customers manage their accounts through a smartphone app or the company website, with an AI assistant and in-app messaging alongside 24/7 human support. It also uses variable direct debits that change each month based on actual energy use. For households with multiple properties, users can manage several homes from a single account.[1]

Prices
These are the tariffs we have pricing for — the supplier may offer others.
The supplier's lowest-priced option is the July 2026 Fixed (15m) V17 deal, estimated at £1,683 annually. This 15-month contract requires a £100 exit fee if customers leave before the term ends.
Households preferring flexibility might consider the Variable Import tariff, priced at £1,805 a year. As a standard variable agreement, it does not tie customers to a fixed term or apply early exit penalties.
Tariff details
This supplier's full tariff range
Fuse Energy offers a range of energy tariffs for different household needs. The line-up includes standard variable options, fixed-rate deals, and specialist tariffs designed for electric vehicle owners and homes that generate their own power.
Customer reviews
On Trustpilot, the supplier holds a rating of 4.8 out of 5 across 8,823 reviews. The majority of this feedback is positive, with 91% of users awarding five stars, compared to 4% leaving a one-star rating.
Feedback indicates that users generally report prompt response times and effective issue resolution, alongside straightforward installation processes. Conversely, some critical reviews highlight initial communication hurdles, noting longer wait times to reach an agent or the necessity of specifically requesting human assistance via the automated chat.
Apps
As a digital-focused supplier, the company's mobile applications receive strong user scores. The iOS version holds a 4.7 out of 5 from 619 ratings, while the Android equivalent scores 4.8 out of 5 across 706 ratings. The Google Play Store data also shows over 100,000 installations and a 95.7% net-positive sentiment.
Software updates are released regularly to implement minor fixes and interface adjustments. A recent sample of iOS feedback points to varied user experiences; while several accounts highlight helpful support interactions, others document technical or service-related issues.
Service and support
| Metric | Fuse Energy |
|---|---|
| Citizens Advice score | N/A |
The company is absent from both the Citizens Advice energy supplier league table and the Which? annual customer survey. Because it is not covered by these independent assessments, there is no comparable Citizens Advice or Which? service data for Fuse Energy.
Instead of traditional telephone call centres, customer service is routed primarily through the smartphone app and website. This system relies on an AI assistant and text-based messaging to manage account queries.
Green energy
Fuse Energy takes a different approach to green energy compared to many mainstream suppliers. It explicitly avoids buying Renewable Energy Guarantee of Origin certificates to label its grid electricity as green, arguing this practice is misleading. Instead, it sells its renewable certificates and uses the money to build real clean energy infrastructure, such as solar farms, wind turbines, and green hydrogen projects.
Because it sells these certificates, the supplier's official fuel mix is not listed as fully renewable. For the 2024 to 2025 period, the electricity it supplies to customers was made up of 16.12% solar, 1.39% wind, and 82.49% grid power. The company owns and runs its own solar farms in southern England and a wind farm in Scotland, aiming to reinvest all its profits into low-cost renewable generation.
Our verdict
Fuse Energy offers strong app-based account management and high customer review scores, though it lacks independent service data from Citizens Advice.
This digital-first provider offers a straightforward choice of fixed and variable tariffs managed via smartphone. While user feedback across app stores and Trustpilot is largely positive, the absence of independent performance data from established consumer groups makes it difficult to benchmark its service against industry averages.
The service may suit households comfortable handling their energy administration entirely through a screen and automated chat. However, those who prefer traditional telephone support or require a supplier with a verified track record in independent rankings might want to explore alternative providers.

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.
