British Gas offers both gas and electricity to homes in the UK. It also offers a range of related services, from home cover to solar panel and heat pump installation. Read on to discover everything you need to know about the UK’s longest established energy company.

The origins of British Gas stretch all the way back to the early 19th century when, in 1812, the Gas Light and Coke Company was formed. After nationalisation in 1948, the company was renamed British Gas in 1973. The brand name remains in use today even after privatisation and acquisition by its current owners, Centrica plc, in 1997.

Until recently. British Gas was the undisputed number one among the Big Six energy companies. In December 2023, however, it lost top spot in the electricity supply market to Octopus. Despite this, British Gas is still the second biggest electric supplier with a market share of 20.3%. It remains the number one gas supplier, however, with 27.8% of the market. In total British Gas supplies over eight million homes and businesses in the UK with electricity and/or gas.

Over 195,000 customers have reviewed British Gas on TrustPilot as of April 2024, giving it an average score of 4.1 stars. Of those, 54% have been 5-star reviews. This places it 24th out of 167 electric utility companies.

British Gas dual fuel, electric-only and gas-only plans are available to all customers. It offers both variable and fixed-rate tariffs. In addition to a standard fixed energy tariff, British Gas also offers specialist fixed energy deals for electric vehicles as well as those with Dimplex Quantum storage heaters.

The company also offers a standard variable tariff. British Gas’s standard tariff’s price per kWh tracks Ofgem’s energy price cap, so changes every three months. There is also a Safeguard PAYG for those with a prepayment meter.

British Gas also offers the following services, which are also available to non-energy customers:

  • HomeCare cover: A range of products protecting various parts of the home, including boiler and heating, home electrics, plumbing and drains, and more.
  • Repair: British Gas engineers can also be hired to perform boiler, appliance, home electrics and plumbing and drains repairs.
  • Heating systems: You can also use British Gas to fit new and replacement boilers, plus service existing ones. It can also fit heat pumps, thermostats and thermostatic radiator valves.
  • Greener homes: In addition to fitting free smart meters, British Gas also offers installation services for solar panels, air source heat pumps, electric vehicle chargers and home insulation.

British Gas supports both standard credit and prepayment meters. Most standard tariffs will work with both smart and non-smart meters, but some newer tariffs may require a smart meter be fitted first.
