The UK's oldest and best-known energy brand
British Gas traces its roots to the Gas Light and Coke Company founded in 1812 and is part of Centrica plc. It is the UK's largest domestic energy supplier by name recognition, serving around 7 million homes. Beyond energy supply, British Gas offers boiler cover, home services and smart home products through its Hive brand.
Default variable tariff capped at the Ofgem price cap. No exit fees.
Price certainty for 12 or 24 months. Exit fees typically apply if leaving early.
100% renewable electricity backed by REGO certificates. Slight premium over the standard variable rate.
Energy supply combined with a Hive smart thermostat and installation discount.
Switching away from British Gas on a variable tariff is free with no exit fees. Fixed tariffs may carry exit fees of up to £75 per fuel — check your contract before switching.
British Gas offers a Green Future tariff backed by REGO certificates but does not generate its own renewable power. It is not considered a primary green supplier by independent environmental organisations.
