Check prices at British GasWhat a British Gas quote has to beat
Every tariff compared →British Gas doesn't publish its prices in a form I can use, so I can't cost its tariffs. Give me your postcode for the cheapest tariffs I hold for your home and the price cap, then set British Gas's quote against them.
Pricing a medium home: Direct Debit, gas and electricity. Ofgem's figures for homes that use less than most (1,600 kWh of electricity, 6,000 kWh of gas), about the middle and more. Your bill or your supplier's app gives a truer answer.
British Gas: what to know before you buy
British Gas sells fixed, tracker and standard variable tariffs. Its Fix & Fall tariff fixes your prices for two years and lowers them if prices fall.
Smart and prepayment tariffs
- An EV tariff with cheaper overnight rates
- A heat pump tariff with half-price electricity for 70 hours a week
- Charge Power, for charging a home battery overnight at half price
- A Smart Export Guarantee tariff that pays for power you export
- Prepayment tariffs
British Gas's prices aren't in my energy comparison, because it doesn't publish them in a form I can use. To see what it would charge for your home, get a quote on its site, then set that figure against the cheapest deals in my comparison for your region.
To switch, get a quote online. Existing customers can also move to PeakSave, which gives half-price electricity on Sunday daytimes.
