British Gas Energy Deals UK

Q: Are British Gas tariffs the cheapest in 2026?

Not for most households. British Gas fixed deals are competitive but typically not the lowest price in the market. Smaller suppliers often undercut British Gas on unit rates. Running a whole-of-market comparison is essential before committing.

Q: What exit fees does British Gas charge?

British Gas charges £50 per fuel on its shorter fixed tariffs and £75 per fuel on its longer fixed tariff. On a dual fuel contract, that is £100 or £150 total. Exit fees are waived in the final 49 days of the contract under Ofgem rules.

Q: Does British Gas have an EV tariff?

Yes. The EV Power tariff provides a night rate of 7.9p/kWh between 12am and 5am. It works with any EV model and any home charger. Pairing with Hive Power+ reduces the effective rate to approximately 6.75p/kWh.

Q: What is the British Gas Tracker tariff?

The Tracker is a variable tariff where unit rates move with the Ofgem price cap every quarter. You receive a guaranteed discount on standing charges. There are no exit fees.

Q: Is British Gas the same as Scottish Gas?

Yes. British Gas trades as Scottish Gas in Scotland. The tariffs, pricing structure, and customer service teams are identical. Scottish customers see the Scottish Gas branding but the underlying company is Centrica.

Q: What is PeakSave and can I access it on any tariff?

PeakSave gives you half-price electricity every Sunday from 11am to 4pm. It is open to all British Gas electricity customers with a working smart meter, on any tariff. PeakSave Green Flex events offer additional savings during high-renewables periods.

About British Gas

British Gas is part of the Centrica Group and one of the UK's 'Big Six' legacy energy suppliers. It supplies gas and electricity to homes across England, Scotland, and Wales, trading as Scottish Gas north of the border. In addition to energy supply, British Gas offers the Hive smart home ecosystem (smart thermostats, EV charging management) and optional home services including boiler cover and central heating protection.

Customer service improvements have been genuine. 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 the second consecutive year. However, the company still recorded nearly 597,000 complaints in 2025, high by comparison to best-in-class suppliers. The engineering network, over 6,000 engineers available 24/7, is a consistent strength.

Is British Gas the Cheapest Energy Supplier in 2026?

Not for most households. But here is how much you could save by switching away from the BG SVT.

1-bed flat / single occupant (~£935/yr on SVT)

Potential saving: £80 to £150/year by switching to the best available fixed deal.

2 to 3 bed house / couple (~£1,641/yr on SVT)

Potential saving: £150 to £280/year. The most common household type, and the biggest saving opportunity.

3 to 4 bed family home (~£2,460/yr on SVT)

Potential saving: £250 to £400/year. Higher usage = higher absolute saving from switching.

Electricity-only / no gas (~£820/yr on SVT)

Potential saving: £60 to £130/year. Fewer suppliers compete but savings still available.

Is British Gas worth the premium over cheaper alternatives?

British Gas prices consistently sit above challenger suppliers like Octopus Energy and OVO. What you pay for is an established UK engineer network of over 6,000 engineers, next-day service appointments, and HomeCare boiler cover packages that smaller providers cannot replicate.

For households with an older boiler or ongoing maintenance needs, that premium can pay for itself quickly. For households with a recently serviced system and no maintenance contract, a cheaper fixed-rate tariff almost always saves more over the year.

Switch compares British Gas tariffs against every available alternative in real time, including unit rates, standing charges, and projected annual cost, so you can decide in minutes whether the loyalty is worth the price.
