British Gas is one of the most recognisable brand names in UK energy, and many people wonder about its ownership structure, particularly given the history of privatisation and the changes in the energy sector over recent decades.

British Gas and Centrica

British Gas is a trading name owned by Centrica plc, a publicly listed company traded on the London Stock Exchange. Centrica was formed in 1997 when British Gas plc, which had been privatised from nationalised state ownership in 1986, was demerged into two separate companies. Centrica took the consumer-facing businesses, including British Gas's domestic energy supply and services operations. The other company, BG Group, took the exploration and production assets and was later acquired by Royal Dutch Shell in 2016.

Centrica is headquartered in Windsor and operates primarily in the UK and North America. In the UK, British Gas is Centrica's primary consumer brand for residential energy supply, boiler and central heating services, and home insurance products.

Market Position

British Gas remains the largest domestic energy supplier in the UK by customer numbers, though its market share has declined significantly from the near-monopoly position it held at privatisation as the energy market was liberalised and competing suppliers entered the residential market. British Gas serves millions of households for gas and electricity supply and is also one of the largest providers of boiler installation and maintenance services in the UK through its Homecare product range.

Regulation

British Gas, like all UK energy suppliers, is regulated by Ofgem, the Office of Gas and Electricity Markets. Ofgem sets the price cap that limits the maximum unit rate and standing charge that suppliers can charge domestic customers, and regulates various aspects of how energy is supplied, billed, and how customer disputes are handled.

Summary

British Gas is owned by Centrica plc, a UK-listed energy company formed from the demerger of privatised British Gas plc in 1997. British Gas is Centrica's UK consumer brand for residential energy supply and home services. It remains the largest UK domestic energy supplier by customer numbers. Centrica is listed on the London Stock Exchange under the ticker CNA.
