Quick summary
Fuse Energy is one of the newest electricity suppliers in Great Britain and the first to launch after the 2021 energy crisis. It’s co-founded by ex-Revolut executives Alan Chang and Charles Orr, with former Ofgem CEO Dermot Nolan among its advisers.
Fuse focuses on low prices (it markets variable tariffs that beat the Ofgem price cap), a slick app/web experience, and building its own UK renewables. Support is 24/7. As of August 2025, Fuse has also announced an expansion into domestic gas (availability is rolling out).
Who are Fuse Energy?
Fuse Energy launched publicly in July 2023, widely reported as the first new UK supplier since the energy market crisis. The founders are Alan Chang (CEO) and Charles Orr (COO), and the company lists Dermot Nolan (ex-Ofgem chief executive) as an adviser, bringing regulatory and market experience to a fintech-style entrant.
Fuse is vertically integrated and already owns UK renewable generation: the Netley North solar park in Hampshire (5.2 MW), Bullous Park in Devon (12 MW), and the Balnamoon onshore wind turbine in Moray (0.8 MW). That’s ~18 MW of operational wind and solar capacity today, with the portfolio and pipeline growing.
What tariffs do Fuse Energy offer?
Fuse now offers a range of electricity tariffs (not just one). The line-up currently includes:
- Variable tariffs positioned to beat the UK price cap
- Fixed tariffs (price certainty for 12–18 months; exit fees apply)
- Multi-rate (time-of-use) tariffs for homes that can shift usage
- EV tariffs with cheap off-peak rates for home charging
You can sign up via the website or the app (it’s no longer app-only), and the company advertises that you can switch in under 3 minutes.
Smart meters: For single-rate supply, you can still submit manual readings if needed; multi-rate/EV tariffs generally require a smart meter. (Fuse’s supply terms cover both automatic smart reads and manual reads on request.)
Exit fees: Fuse’s fixed deals charge an exit fee if you leave early. Recent market listings put this at £50 on fixed plans – always check the fee shown at sign-up. (Variable tariffs have no exit fee.)
Gas: In late July 2025, Fuse announced its entry into the domestic gas market following a new funding round. Availability appears to be rolling out; check your postcode for current options.
Are Fuse Energy cheap?
Fuse’s core pitch is straightforward: its variable electricity tariff aims to sit below the Ofgem price cap (a useful benchmark for comparing SVTs).
For context, the Ofgem cap (1 July–30 September 2025) averages 25.73p/kWh for electricity with a 51.37p/day standing charge (Direct Debit).
If Fuse’s variable tariff in your region undercuts those figures, it will usually be among the more competitive electricity-only options, though the cheapest supplier can vary by region, meter type, and usage.
You can find out how much it will cost you based on your usage using our handy electricity bill calculator.
The Octopus Energy Tracker tariff may be cheaper depending on your usage, but apart from that, no other supplier offers a variable electricity tariff cheaper.

What do other Fuse Energy reviews say?
As they are such a new supplier, there are currently many Fuse Energy reviews from customers.
However, they have received over 180 reviews on Trustpilot, which are generally very positive. They have an average score of 4.5 out of 5, with 86% giving them a 5-star review.
How green is Fuse’s energy?
Unlike suppliers that badge their regulated fuel mix as “100% renewable” by retiring REGOs, Fuse sells its REGOs and says it reinvests the proceeds into building new clean-energy infrastructure (including R&D such as green hydrogen).
As a result, its regulated fuel-mix disclosure is not shown as 100% renewable, a deliberate transparency choice explained on its site. Operationally, Fuse highlights 18.9 GWh of generation from its own sites over the most recent period disclosed and details of its UK assets (see above).
What is Fuse Energy’s customer service like?
Support hours: Fuse promotes 24/7/365 live chat with a London-based team via its app/web.
Trustpilot: 4.7/5 from ~911 reviews today (1 Aug 2025). As with all review platforms, ratings change—quote the live figure when you publish.
Citizens Advice star ratings: Fuse doesn’t appear in the main CA table yet (that’s limited to suppliers with >25,000 accounts), but it is listed in the “smaller suppliers” section with basic info.
What is Fuse Energy’s website/app like?
Fuse is app-first but now offers a full web sign-up and account experience. The pitch: “sign up in under 3 minutes”, usage and bill forecasts updated every 30 minutes, and a modern dashboard for meter reads, payments and support.
Who is Fuse best for?
Fuse suits electricity-only households who are happy to keep gas with a different provider, or who live in areas where Fuse’s gas supply is beginning to roll out.
It’s also a strong match for cost-conscious customers who want a variable tariff designed to sit under the Ofgem price cap, or a competitive fixed deal, so long as you’re comfortable checking any early exit fees before you switch.
If you prefer managing your energy digitally, Fuse’s tech-first approach with 24/7 chat, self-service features, and a clean app/web dashboard will likely appeal.
Finally, lower-to-average electricity users may benefit from Fuse’s competitive standing charges, while EV owners can take advantage of off-peak rates on dedicated EV tariffs.
What’s changed since early 2024?
Fuse has moved from a single offer to a broader range of tariffs, including variable, fixed, multi-rate (time-of-use) and EV options. Sign-up is no longer app-only, so you can now switch via the website as well. Customer support is 24/7, with round-the-clock chat available.
In 2025, the company also announced entry into domestic gas, which is rolling out by postcode. And while Fuse promotes a build-new-renewables model, its fuel-mix disclosure explains why it doesn’t label itself “100% renewable” in the regulated sense (it sells REGOs and reinvests the proceeds in new projects).
Pros & cons
On the plus side, Fuse offers variable tariffs that aim to beat the Ofgem cap, 24/7 in-app/web support, and a polished digital experience. It also owns UK renewable assets and is transparent about how it supports new green generation.
The trade-offs: gas supply is newly announced and not yet universal, so dual-fuel convenience may still mean using two suppliers for now. Some fixed deals carry exit fees, so check the small print before switching. And as a newer supplier, Fuse doesn’t yet appear in Citizens Advice’s main star-rating table (which is limited to larger providers).
Verdict: Is Fuse Energy a good choice in 2025?
If you’re comfortable with a digital-first supplier and want sharp electricity pricing, Fuse is well worth considering. Its below-cap variable and fixed/multi-rate/EV options provide flexibility, the renewables-first strategy is credible and backed by owned UK assets, and 24/7 support is a genuine differentiator.
The main caveats are gas availability (rolling out) and exit fees on some fixes.
Overall, Fuse is one of the most interesting post-crisis challengers, and a particularly strong option for electricity-only or EV-focused households.
