Fuse Energy vs British Gas: Which Should You Choose?

Fuse Energy vs British Gas comes down to price, service and how you want to pay: Fuse is a newer app-led supplier with a wider spread of fixed deals, while British Gas is the UK’s largest established supplier with phone support and its own engineers. Neither is automatically cheaper for every home, and the cited market snapshots for August 2026 do not show either one heavily undercutting the Ofgem price cap.

If you are on a standard variable tariff sitting at or above the price cap, the decision is less about the brand and more about whether a fixed deal saves you money against your usage, and whether you value app-first control or traditional phone and engineer support. Free Price Compare sources tariff and cap data from Ofgem publications and live supplier feeds, so this comparison focuses on what the current figures actually show rather than headline marketing.

How Fuse Energy and British Gas compare at a glance

Fuse Energy is an app-led UK energy supplier that offers pay-for-what-you-use billing and multiple fixed-term tariffs, while British Gas is the UK’s largest established supplier, part of Centrica, with phone support, its own engineers and a cap-tracking Standard Variable Tariff. In the August 2026 market snapshot, British Gas’s SVT sat at around £1,663 a year with no exit fee, and Fuse’s cheapest named deal was around £1,683 a year on a 15-month fix with a £100 exit fee. Both are regulated by Ofgem, so the core protections are identical; the practical differences are price against your usage, exit fees, and how you prefer to manage your account.

Figures are indicative and may change.

Is Fuse Energy cheaper than British Gas?

Fuse Energy is not reliably cheaper than British Gas across the board in the August 2026 data, and the reverse is not true either. In the cited snapshot, Fuse’s cheapest named fix was around £1,683 a year while the British Gas Standard Variable Tariff sat at around £1,663 a year, so the established supplier’s default deal was marginally lower in that example. Whether a fix beats a variable tariff depends entirely on your annual consumption, your region and where the Ofgem price cap sits, because both suppliers price partly against that cap. The only dependable way to know which is cheaper for your home is to run a comparison on your own address and usage rather than trusting a single headline figure.

What is the energy price cap and why does it matter here?

The energy price cap is the maximum that suppliers can charge for each unit of gas and electricity and for the standing charge on standard variable and default tariffs, set by Ofgem and updated every three months. For a typical dual-fuel household paying by Direct Debit, the cap works out at around £1,862 a year from 1 July to 30 September 2026, up 13% from the previous £1,641 (Ofgem, published 27 May 2026). The cap limits rates, not your total bill, so a heavy user pays more than a light user even on the same capped tariff. Both British Gas’s SVT and Fuse’s variable tariff are anchored to this cap, which is why neither shows large undercutting in the source data. Understanding the cap is the reference point for judging whether any fixed deal is good value.

• Electricity capped at 26.11p/kWh with a 57.19p daily standing charge (Ofgem, 1 July to 30 September 2026).
• Gas capped at 7.33p/kWh with a 29.04p daily standing charge (Ofgem, same period).
• Ofgem’s next cap review is due in August 2026, effective from 1 October 2026.

Should you pick a fixed tariff or stay on the standard variable tariff?

Choose a fixed tariff if you want price certainty and the fixed rate is below where you expect the price cap to sit over the term; stay on the standard variable tariff if you want no exit fees and the flexibility to switch freely. A standard variable tariff is a default deal whose unit rates move with the Ofgem price cap every quarter, while a fixed tariff locks your unit rates for a set term, usually 12 to 24 months. British Gas’s SVT example carried no exit fee and tracked the cap at around £1,663 a year, whereas its Exclusive Fix Feb27 example was around £1,683 a year on a 14-month term with a £50-per-fuel exit fee. Fuse’s fixed deals showed exit fees of around £50 to £100 in the cited feeds. The trade-off is protection against future cap rises versus the cost of leaving early if rates fall. Our British Gas exit fees and switching guide breaks down when a fix is worth the lock-in.

Does British Gas have exit fees that Fuse does not?

British Gas fixed tariffs generally carry exit fees of around £50 per fuel, meaning a dual-fuel customer could pay around £100 to leave early, while its Standard Variable Tariff has no exit fee at all. Fuse Energy’s fixed deals in the August 2026 data showed exit fees of around £50 on shorter terms and £100 on a 15-month fix, so neither supplier is consistently cheaper to exit. An exit fee is a charge for ending a fixed contract before its term ends, and it does not apply if you switch during the 14-day cooling-off period after signing up, or in the final weeks before the fix ends when suppliers must let you leave penalty-free. If you switch a lot to chase deals, a no-exit-fee variable tariff avoids these charges entirely, which is a point in favour of the British Gas SVT for frequent switchers.

Is Fuse Energy any good, and are its reviews reliable?

Fuse Energy is a fully Ofgem-licensed UK supplier, so its supply, billing and complaint-handling are held to the same regulatory standards as British Gas, and it operates as a smaller app-focused challenger rather than a nationwide brand. The cited sources do not verify Fuse’s Trustpilot score, customer numbers or satisfaction ratings, so treat any specific review figure with caution and check the current rating directly before you switch. Its main draws in the source data are a wider spread of fixed tariffs and pay-for-what-you-use billing, where you are charged for actual consumption rather than a smoothed fixed monthly amount. The main trade-off against British Gas is the absence of a large phone-support operation and an in-house engineer network.

Does Fuse Energy offer phone support like British Gas?

British Gas offers established phone support alongside its app and online account, backed by its own workforce of engineers, while Fuse Energy runs a more app-first support model as a smaller challenger supplier. For a household that wants to speak to someone quickly, or that needs boiler and heating engineers from the same brand, British Gas has the stronger practical offering. Fuse’s approach suits customers comfortable managing everything through an app and online messaging. Whichever you choose, both are covered by the Ofgem complaints framework, and if a complaint is not resolved within eight weeks you can escalate free of charge to the Energy Ombudsman. If phone contact matters to you, note that British Gas customer service and account login are among the most-searched British Gas queries, reflecting how many households rely on that direct support.

How does the switch between British Gas and Fuse actually work?

Switching between British Gas and Fuse Energy is handled by your new supplier and typically completes within five working days once you have submitted a meter reading, with a 14-day cooling-off period during which you can cancel without penalty. Start by taking a meter reading and checking whether your current tariff has an exit fee, because leaving a fixed deal early can trigger a charge of around £50 to £100. Your new supplier notifies your old one, so you do not need to contact British Gas or Fuse separately to end the old contract. Watch two things when switching: any Warm Home Discount or credit balance should transfer or be refunded, and you should keep a note of your final and opening meter readings to avoid billing disputes.

Which supplier is the better choice for your household?

British Gas suits households that value phone support, in-house engineers and a no-exit-fee default tariff, while Fuse Energy suits app-comfortable customers who want a wider choice of fixed deals and pay-for-what-you-use billing. In the August 2026 snapshot the price gap between the two was small, with the British Gas SVT at around £1,663 a year and Fuse’s cheapest named fix at around £1,683 a year, so price alone rarely settles the decision. If you are on a standard variable tariff sitting at or above the Ofgem price cap of around £1,862 a year, the more important question is whether any available fix beats the cap for your usage over its full term. Run a comparison on your postcode and annual consumption, then weigh the cheapest result against the support features you actually use.
