British Gas

British Gas, energy and home services in the UK

British Gas presents itself as the UK's largest energy and home services company. It supplies gas and electricity, sells boilers and maintenance cover, and provides other home services. The company is part of Centrica PLC and claims over 200 years of operation, as well as a customer base of nine million and a presence in more than eight million homes and businesses in Great Britain.

Gas and electricity supply

British Gas's core business is the supply of gas and electricity. The company states that it serves more than eight million homes and businesses in Great Britain, a figure it presents as higher than any competitor. For customers interested in reducing emissions, it offers smart time-of-use tariffs and publishes information about the source of its electricity and its environmental impact.

Boilers, heating, and HomeCare cover

British Gas sells boilers and installation services, and states that its installations have passed the rigorous Which? Trusted Traders assessment process. The company has nearly 7,000 engineers to handle repairs and maintenance. Its HomeCare product includes cover with repairs, annual boiler service, and the option to upgrade or change the plan. For those without HomeCare, it offers one-off boiler and heating repairs, plumbing and drains, electrics and appliances, with the option to add ongoing cover.

Services for landlords

The company offers landlords tools to keep their properties compliant and protected, such as Gas Safety Certificates, EICRs (Electrical Installation Condition Reports), boiler cover, and other compliance-oriented services.

Electric mobility and low-emission technologies

British Gas sells electric vehicle tariffs and home charging products. Its offering combines the EV tariff with Hive Power+, a system that allows charging the vehicle during off-peak hours with discounts. The company also sells heat pumps, solar panels and batteries, Hive smart heating, EV chargers, insulation, and home energy assessments (Home Health Check).

Environmental and community commitment

British Gas maintains that around 40% of the UK's carbon emissions come from homes and that it is working to reduce that figure. The company has launched a £140 million support fund for customers and participates in the British Gas Energy for Tomorrow programme, which has helped five local sports clubs install solar panels and improve their facilities. It also collaborates with sports organisations such as Team GB, Paralympics GB, Scottish Rugby, Scottish Football, and the Women's Super League Football.

Awards and ratings

The company was recognised with the Best Overall Improvement award at the Uswitch Energy Awards 2025, and more than 155,000 customers rate it five stars on Trustpilot. British Gas Services Limited earns commission from the sale of insurance products, as the company itself states.
