Prices
Prices shown cover selected tariffs; other plans may be available.
Fuse Energy's cheapest available tariff is the August 2026 Fixed (18m) V15, which costs £1,489 a year. This is a fixed deal with an 18-month term and carries a £100 exit fee.
The supplier also offers a standard variable option, called Variable Import, which costs £1,611 a year. This tariff has no fixed term and does not charge exit fees.
Tariff details
Fuse Energy offers a mix of standard and fixed-rate tariffs for domestic households. Its standard variable tariff offers flexibility with no exit fees, while its fixed deals allow customers to lock in their energy prices for terms ranging from 12 to 24 months.
Customer reviews
Fuse Energy has a Trustpilot rating of 4.8 out of 5, based on 10,754 reviews. The majority of feedback is positive, with 92% of reviewers giving a five-star rating, while 3% leave a one-star review.
Review sentiment indicates general satisfaction with the service. Users frequently highlight helpful staff and report that the process of switching to the supplier is straightforward.
Feedback also points to prompt response times during account setup and when resolving unexpected issues. Reviewers note that the support team assists effectively with technical hurdles.
Because Fuse Energy is a newer supplier, it does not currently have a customer satisfaction score from the annual Which? survey.
Apps
Because Fuse Energy is an app-based supplier, its mobile applications are the primary method for customers to manage their accounts. The iOS app has a score of 4.8 out of 5 from 717 ratings on the App Store, and the Android version scores 4.7 out of 5 from 821 ratings on Google Play.
The Android app shows over 100,000 installs, and both versions receive regular updates. A recent sample of iOS reviews highlights responsive customer support through the app's chat feature, though a few users noted some general company service issues.
Service and support
Customer support is handled through a 24-hour in-app chat service rather than traditional phone lines. The supplier does not currently have data available for the Which? customer service or complaints rankings.
Complaints performance
Complaint figures are withheld from this repaired draft because no source URL was supplied for independent verification.
Green energy
Fuse Energy takes a different approach to green energy than many other suppliers. It does not buy Renewable Energy Guarantee of Origin (REGO) certificates to label its tariffs as 100% renewable, arguing that this practice is misleading because the physical energy still comes from the national grid. Because it does not use certificates to offset its grid power, its published fuel mix reflects the standard grid average. 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.
Instead of buying certificates, the company builds and runs its own renewable energy projects, including solar farms in southern England and a wind farm in Scotland. It sells the renewable certificates it earns from these sites and reinvests all of its profits into developing new renewable generation and green hydrogen projects across the UK. Its long-term goal is to supply its customers directly from its own zero-carbon wind and solar projects.
Verdict
Fuse Energy offers highly rated app-based account management and fixed tariffs, but lacks independent Citizens Advice data on its customer service.
Fuse Energy may suit households who are comfortable managing their energy entirely through a smartphone app. It has high customer review scores and offers a choice of fixed tariffs, but the lack of independent Citizens Advice service data means there is less visibility into its performance in that league table.
If you are content with in-app chat support and variable direct debits, it may be a suitable choice. However, households that prefer traditional phone support, paper bills, or a supplier with a proven Citizens Advice track record may prefer to compare other options.

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.
