Fuse Energy is a privately owned energy company founded in 2022 by Alan Chang and Charles Orr, who previously worked at Revolut.
The wider Fuse team includes people with experience at companies including Tesla, Voltalia and Jump Trading. Fuse is headquartered in London.
The short answer: Fuse regularly competes towards the cheaper end of the market, but no supplier is cheapest for every household. What you pay depends on where you live and how much gas and electricity you use.
Fuse regularly competes towards the cheaper end of the UK energy market, but there is no single supplier that will always be cheapest for every household.
Energy tariffs change frequently. The amount you actually pay will also depend on factors including where you live and how much gas and electricity you use.
Fuse owns renewable generation assets, trades energy and sells directly to customers. Its business model is designed to reduce the number of intermediaries between electricity generation and the household customer.
The best way to establish whether Fuse is currently cheaper for you is to compare its latest tariff against other available deals using your postcode and actual energy consumption.
Fuse offers fixed and variable energy tariffs, with prices changing as new versions are launched.
| Tariff Name | Electricity Unit Price | Electricity Standing Charge | Gas Unit Price | Gas Standing Charge |
|---|
The typical annual cost is based on Ofgem's medium-use household consuming 2,500 kWh of electricity and 9,500 kWh of gas annually and includes VAT. Prices vary according to region and consumption.

Fuse is a relatively new supplier, having been founded in 2022, but it has expanded rapidly and now supplies more than 400,000 UK homes.
Its service is built predominantly around digital account management. Customers can manage their account, monitor energy use and contact customer support through the Fuse app.
Fuse says its in-app customer support operates 24 hours a day, 365 days a year, with typical response times of under two minutes.
As with any supplier, reliability should not be judged purely on price or headline customer scores. It is worth considering how the company deals with billing problems, smart meters, switching and other problems when they arise.
Fuse Energy has a Trustpilot score of 4.8 stars from more than 10,700 reviews. As expected, they have a high number of positive reviews.
There are some poor reviews, which is expected of all energy suppliers, but it is good to see Fuse Energy actively responds to these types of complaints.
Fuse Energy is likely to appeal particularly to customers who are comfortable managing their energy account digitally and want detailed information about their consumption and spending.
Its tariffs have also competed strongly on price.
However, whether you should switch depends primarily on the tariff available to your household. Don't choose a supplier based on its headline national price alone: compare using your postcode and your own annual gas and electricity consumption.
If Fuse comes out competitively, you can then consider factors such as customer service, tariff terms, exit fees and how comfortable you are managing your account online.
Switching takes around three minutes. You enter your postcode and information about your home through the Fuse website or app, after which Fuse handles the switching process with your existing supplier. There should be no interruption to your gas or electricity supply when you change supplier.
No. Fuse Energy do not currently offer business energy rates.
For businesses considering switching to a cheaper energy tariff, they should compare a quotation against offers from other commercial energy suppliers. Do not rely on domestic tariff prices as an indication of what they will pay.
Businesses should also consider the length of the contract, unit rates, standing charges and any other contractual terms before agreeing to a new energy deal.
Fuse supplies both electricity and gas to domestic customers and puts considerable emphasis on developing physical renewable-energy generation.
It takes a somewhat different approach to suppliers that market electricity as "100% renewable" primarily through Renewable Energy Guarantees of Origin (REGOs).
Fuse says it sells the renewable certificates associated with its generation and reinvests the revenue into developing further clean-energy infrastructure.
Between 1 April 2024 and 31 March 2025, Fuse generated 18.9 GWh of electricity from its own solar and wind farms, which it says was enough electricity to power around 7,000 homes.
Fuse is built around digital account management, with customers able to manage their energy through its app rather than relying on paper bills.
Features include:
Fuse also offers web access if you would rather manage your account through a browser.
Fuse has expanded beyond household energy supply into electric vehicle charging.
Its EV products include:
Customers can therefore combine their household energy supply and compatible EV charging within the Fuse ecosystem.
If you own an electric car, compare the total charging cost and tariff structure rather than simply looking at the headline electricity rate. The cheapest conventional household tariff will not necessarily be the cheapest tariff for a household doing substantial overnight EV charging.
Fuse's customer service is primarily digital.

Fuse Energy is a relatively young supplier, but it has grown rapidly and established itself as a serious competitor in the UK household energy market.
Its main attractions are competitive tariffs, detailed digital account management and an unusual approach to renewable energy that focuses on investing in physical generation rather than relying solely on renewable certificates.
Customer feedback is another significant positive. Its 4.8 out of 5 Trustpilot rating from more than 10,700 reviews as of September 2026 is backed by recurring positive comments about customer support, switching, billing information, pricing and smart meter installation.
Price should still be the starting point. Energy tariffs change frequently, and a deal that is among the cheapest today may not remain there. Compare Fuse's latest tariff using your postcode and actual consumption, then consider customer service, tariff terms and digital account management before deciding whether it is right for you.
