Fuse Energy is one of the UK’s newest energy suppliers, founded in 2022 and headquartered in London. It supplies gas and electricity to more than 400,000 homes, and positions itself as a low-cost, technology-led alternative to traditional suppliers, with tariffs designed to stay below the Ofgem price cap.

The company was set up by Alan Chang and Charles Orr, who previously worked at Revolut, and describes itself as driven by engineers and problem-solvers. It owns and operates its own renewable generation, including solar farms and wind, and reinvests in new clean-energy infrastructure.

Fuse is built around digital account management. You manage everything through the Fuse app or website, with no paper bills and no customer service phone line. The app gives real-time usage updates, forecasts and 24/7 in-app support. One account can also cover several properties, which can be useful for landlords, second-home owners, or anyone managing bills for relatives.

Fuse Energy tariffs

Fuse offers a small range of tariffs, all managed digitally and paid by variable Direct Debit. Here is a summary of the main options.

Variable
Rates move in line with the Ofgem price cap, and Fuse aims to undercut the cap by a few percent, partly through lower-than-average standing charges.
Fixed
Fixed-rate tariffs over 12 or 15-month terms, designed to track below the price cap. Exit fees can be avoided by switching to Fuse’s variable tariff during the term.
Multi-rate
Different rates for peak and off-peak usage, so you can save by shifting consumption to cheaper hours, useful for EV charging or running appliances overnight.

One point to be clear on: Fuse uses variable Direct Debit only, which adjusts each month in line with the energy you actually use, rather than a fixed monthly amount. It does not support prepayment meters, cash payment, or traditional fixed Direct Debit. This offers flexibility and transparency, but may not suit households that prefer a predictable, identical bill each month.

Fuse has also expanded into electric vehicle charging, offering Easee One 7.4kW home chargers, cables and accessories, with EV charging integrated into the app. If you charge an EV at home, it is worth comparing the total charging cost rather than the headline electricity rate.

Fuse and renewable energy

Fuse takes an unusual approach to green energy. Rather than marketing its electricity as “100% renewable” by buying Renewable Energy Guarantee of Origin (REGO) certificates, as many suppliers do, Fuse owns real renewable generation and says it sells the certificates linked to that generation, reinvesting the proceeds into developing further clean-energy infrastructure.

Between April 2024 and March 2025, Fuse generated 18.9 GWh of electricity from its own solar and wind farms, which it says was enough to power around 7,000 homes. This means Fuse does not present its tariffs as 100% renewable in the usual sense, so if a certificate-backed green tariff is specifically what you are after, it is worth comparing against suppliers that offer one.

Fuse Energy customer reviews

Fuse Energy scores [X out of 5] on Trustpilot, based on [X reviews], which is among the highest in the market. Reviews frequently praise its customer support, switching experience, clear billing information, pricing and smart meter installation, and Fuse responds to its poorer reviews to help resolve problems.

As with any supplier, and particularly a newer one, it is worth looking beyond the headline score at how a company handles billing, smart meters and switching when things go wrong. Reading recent reviews before switching will give you the fullest picture.

Expert view

“Fuse has grown fast, and its pricing and app-based service have clearly won a lot of customers over. I like that it owns real renewable generation rather than just buying certificates, which is a genuinely different model. The trade-offs are that it is digital-only, with no phone line and variable Direct Debit as the only way to pay, so it will not suit everyone, and it is still a young supplier. As always, compare its live tariff against your own usage before deciding.”

Is Fuse Energy right for you?

Fuse Energy is likely to appeal if you are comfortable managing your energy account through an app, want detailed information about your usage and spending, and like the idea of competitive tariffs that track below the price cap. Its own renewable generation and EV charging options are a bonus if those matter to you, and the multi-property account is handy if you manage bills for more than one home.

It is less likely to suit you if you want a phone line to call, a fixed monthly Direct Debit, a prepayment meter, or a certificate-backed 100% renewable tariff. As always, compare Fuse’s latest tariff using your own postcode and usage before switching, as new-supplier prices can change.
