Should you fix with British Gas or stay under the price cap?

As of 7 October 2026, Ofgem’s dual-fuel Direct Debit price cap is £1,723 for a typical household through 31 December 2026. British Gas still sells fixed tariffs for peace of mind — including Fix & Fall, which fixes prices for two years with a review that can reduce them if prices fall — alongside shorter fixes, Tracker and smart time-of-use options.
A British Gas fix is only worth taking if the full quote for your postcode beats sticking on a standard variable tariff under the cap, after exit fees. Compare the market before you lock in. We may earn a commission if you buy through MoneySuperMarket via our link.

The October–December 2026 cap of £1,723 limits unit rates and standing charges on default tariffs for a typical Direct Debit dual-fuel home. It does not cap your total bill if you use more than typical. A fixed tariff locks your unit rates for 12 or 24 months. That helps if you expect the January 2027 cap to rise. It can look expensive if wholesale prices fall and variable deals drop.
British Gas’s own site (checked 7 October 2026) still leads with fixing for peace of mind and highlights Fix & Fall as a two-year style product that can reduce prices if the market falls. Exit fees on British Gas fixes are commonly framed as £50 per fuel on shorter fixes and £75 per fuel on longer fixes, waived in the final 49 days under Ofgem rules — confirm the figure on your quote.

Which British Gas tariff type suits you in October 2026?

Fix & Fall: what Centrica and British Gas are offering

Fix & Fall was positioned from 26 May 2026 as a Centrica and British Gas way to fix for longer while retaining a path to lower prices if the market softens. British Gas still promotes it on its tariff hub in October 2026.
Treat it as a product to quote properly for your postcode, not as a guaranteed beat-the-cap deal for every home. The review can reduce rates if prices fall. It is still a commitment, so read the review rules on the quote before you choose it over a shorter fix, Tracker, or staying on the price cap.

Existing British Gas customers

New-customer headline fixes are not always the same as the tariffs shown when you are already with British Gas. Do not assume a price advertised to switchers applies to your account.
Existing customers should check PeakSave Sunday discounts, any Hive offers tied to an energy account, and whether moving house can transfer the account. Switching to another British Gas tariff is often done from the app or by calling, and the menu can differ from the public new-customer list.
If your fix is in its final 49 days, Ofgem rules mean exit fees should not block a switch. Compare your logged-in options with a whole-of-market quote before you renew.

PeakSave for customers who already have a smart meter

PeakSave is available to British Gas electricity customers with a working smart meter. Register via the British Gas app or online account and check that your own tariff is eligible.
PeakSave Sundays: half-price electricity every Sunday from 11am to 4pm, credited to your account or prepayment balance. PeakSave Green Flex adds shorter events when the grid is under pressure or renewables are high. Credits are applied after each event.

British Gas vs Octopus

British Gas is the large incumbent, with boiler care and the Hive ecosystem as add-ons. Octopus often wins on pure price and app experience for switchers looking at Flexible and fixed deals.
Neither brand is automatically cheaper for every postcode. Run the same usage through a whole-of-market comparison, then decide whether HomeCare, Hive, or British Gas’s engineer network is worth a premium over a cheaper Octopus quote.

About British Gas

British Gas is part of the Centrica Group and one of the UK’s legacy large suppliers. It supplies gas and electricity to homes across England, Scotland, and Wales, trading as Scottish Gas north of the border. Alongside energy, it offers the Hive smart home range and optional HomeCare boiler cover.
Customer service has improved: complaints fell by more than 20% during 2025, Trustpilot ratings improved to 4.4 stars, and industry benchmarks recognised British Gas for the most improved customer service for a second year. The company still recorded nearly 597,000 complaints in 2025. The engineering network, over 6,000 engineers, remains a reason some households stay.

Is a British Gas fix cheaper than the £1,723 cap?

Not for every home. These ranges are illustrations of what switching off a default tariff can be worth. They are not a British Gas quote.

1

1-bed flat / single occupant

A typical default bill is well under the dual-fuel cap. A cheaper fix elsewhere can still save on the order of £80 to £150 a year.

2

2 to 3 bed house / couple

The October–December 2026 typical dual-fuel Direct Debit cap is £1,723. Beating that with a fix is possible, and missing it is possible, depending on region.

3

3 to 4 bed family home

Higher usage means the cap does not limit the total bill. A unit-rate difference shows up as a larger annual gap.

4

Electricity-only / no gas

The £1,723 figure is a dual-fuel typical. Electricity-only homes need their own quote, not that headline.

Is British Gas worth a premium over a cheaper fix?

British Gas prices often sit above challengers such as Octopus Energy. What some households pay for is an established engineer network of over 6,000 engineers, service appointments, and HomeCare boiler cover that a price-only supplier does not bundle.
For a home with an older boiler, that premium can be rational. For a recently serviced system and no maintenance contract, a cheaper fixed tariff from another supplier often costs less over the year.
Compare British Gas with the rest of the market on unit rates, standing charges and projected annual cost for your postcode, then decide if the extras are worth it.

British Gas: honest pros and cons

Pros

Large UK gas supplier with an established network

Fixed, Fix & Fall, Tracker, EV, heat and prepayment options

6,000+ engineers and HomeCare boiler cover

PeakSave can sit on top of an eligible smart-meter tariff

Hive smart home products tie into an energy account

Most improved supplier recognition in 2024 and 2025, with complaints down more than 20% in 2025

British Gas Energy Trust grants are open more widely than British Gas customers alone

Cons

A British Gas fix is often not the cheapest quote in a whole-of-market comparison

Default-tariff customers pay at the Ofgem cap, with no automatic loyalty discount

Exit fees on fixes reduce flexibility until the final 49 days

Nearly 597,000 complaints recorded in 2025, high versus the best-scoring suppliers

New-customer prices do not always match what existing customers are offered

Who should choose a British Gas tariff?

British Gas makes the most sense if you want energy bundled with HomeCare, you already use Hive, you want an EV or heat time-of-use tariff, or you value a large engineer network over the last pound of unit rate.
If the only goal is the lowest annual bill, compare Octopus, EDF, E.ON Next and the rest of the market on the same usage. Fix & Fall is one option to quote, not a reason to skip that comparison.
