British Gas^ is one of the UK’s largest and oldest energy suppliers, serving millions of homes with gas, electricity and boiler services. Its size and long history mean it’s a household name, but not always the cheapest option on the market. Many customers start looking for alternatives when they see lower tariffs from newer suppliers, want better customer service, or prefer greener energy options. With competition growing, switching can often mean saving money, improving service, or aligning your energy supply with your values.
British Gas Alternatives
While all energy suppliers set their own tariffs, they are bound by the Ofgem energy price cap for standard variable tariffs. This means no supplier can charge more than the cap for a typical household on these plans. From 1 July to 30 September 2025, the cap is £1,720 a year for a typical dual-fuel household paying by Direct Debit, down 7% from the £1,849 set for April to June 2025.
That doesn’t mean all suppliers cost the same. Many compete by offering fixed-rate deals below the cap, additional perks, or better customer service. If you’re looking to move away from British Gas, here are some popular alternatives worth considering.
