British Gas

British Gas is one of the best-known energy and home-services brands in the United Kingdom. It supplies gas and electricity to households and businesses, and also provides services related to heating, boilers, plumbing, electrical systems, appliances and home maintenance. The brand is operated through several Centrica subsidiaries, including British Gas Trading Limited, British Gas Services Limited, British Gas Services (Commercial) Limited, British Gas New Heating Limited and British Gas Insurance Limited. In Scotland, the consumer-facing business trades as Scottish Gas. The brand's institutional roots reach back to the Gas Light and Coke Company, established in London in 1812. That company was the world's first public utility company and expanded over more than a century by absorbing smaller gas undertakings. The Gas Act 1948 nationalised Britain's gas industry and placed the former company within the North Thames Gas Board, one of twelve regional boards. A further restructuring under the Gas Act 1972 consolidated the regional boards into the British Gas Corporation, a state-owned national gas organisation responsible for production, distribution and supply across Great Britain. British Gas was privatised under the Gas Act 1986. Its shares were floated on the London Stock Exchange in December 1986, supported by the highly visible “If you see Sid... Tell him!” campaign. The privatisation transformed British Gas from a state corporation into a publicly traded monopoly supplier. In 1997, the former British Gas plc was divided into separate businesses. The international exploration and production business became BG Group, while the domestic gas sales, trading, services and retail operations were transferred to Centrica. Centrica has continued to operate the British Gas brand. The modern business combines commodity energy supply with recurring home-services and installation work. Its offer has included gas and electricity tariffs, smart meters, boiler installation and maintenance, central-heating cover, plumbing and drainage assistance, electrical services, appliance support and related insurance products. The company also operates service-training facilities known as British Gas Academies and maintains a large field-engineer fleet. In 2020 it announced a plan to replace diesel service vans with electric vehicles by 2025. British Gas has historically been one of the largest UK energy suppliers and is commonly grouped with the former “Big Six” suppliers. It served around ten million homes according to the referenced Wikipedia material and remained the country's largest gas supplier. Its position in electricity retail was challenged by the growth of independent suppliers; in 2024 Octopus Energy overtook it as the largest UK electricity supplier. The company has nevertheless retained significant scale through its household customer base, engineering workforce and established home-services franchise. The brand has faced substantial competitive, regulatory and reputational pressure. Customer losses, the introduction of the UK energy price cap, criticism of customer-service standards, unsolicited-marketing complaints and disputes over employment practices have all affected its public profile. In 2023, media reports concerning the forced installation of prepayment meters led to intense scrutiny. British Gas subsequently said it would stop using the third-party contractor associated with the reported practices. Ofgem later described British Gas's customer-service processes as having “moderate weaknesses” in a review covering the sector. The company continues to operate as an active Centrica brand in the UK energy and home-services market.

British Gas traces its origins to the Gas Light and Coke Company, founded in London in 1812 by Frederick Albert Winsor under a royal charter. The company supplied manufactured town gas and expanded its network through domestic services and the absorption of smaller gas undertakings. Among the businesses absorbed over time were the Aldgate Gas Light and Coke Company, the City of London Gas Light and Coke Company, the Equitable Gas Light Company, the Imperial Gas Light and Coke Company and several regional gas companies. The Gas Act 1948 nationalised the British gas industry. On 1 May 1949, the Gas Light and Coke Company became the principal constituent of the North Thames Gas Board, one of twelve regional gas boards created by the post-war Labour government. A Gas Council coordinated the boards, represented the industry and handled matters such as research and labour negotiations. The Gas Act 1965 increased the council's powers, allowing it to acquire or manufacture gas, supply gas in bulk and borrow substantial sums for industry development. A second major reorganisation followed the Gas Act 1972. The twelve regional boards were merged into the British Gas Corporation, which assumed national responsibility for developing and maintaining Britain's gas supply and meeting reasonable demand. During the late 1960s and 1970s, the industry also converted domestic supplies from coal gas to natural gas following the development of North Sea gas resources. This conversion changed household appliances, distribution operations and the character of the national gas system. The Gas Act 1986 brought privatisation under the Conservative government led by Margaret Thatcher. British Gas shares were floated on the London Stock Exchange on 8 December 1986, and the sale was promoted through the “If you see Sid... Tell him!” advertising campaign. Privatisation made the company a publicly owned commercial enterprise, although it initially retained a powerful monopoly position because it was the only organisation able to supply gas throughout the country. The transaction was criticised by some observers who argued that it replaced a public monopoly with a private one. In February 1997, British Gas plc was divided into separate companies. BG Group inherited the international exploration and production activities, while the gas-sales, gas-trading, services and retail operations were transferred to Centrica. The domestic Morecambe gas-field production interests were also associated with the Centrica transfer. From that point, British Gas became the principal retail and home-services brand of Centrica rather than an independent integrated national gas corporation. During the 2000s and 2010s, British Gas broadened its offer beyond energy supply. It acquired Dyno-Rod in October 2004, strengthening its plumbing and drainage-services capability. The company continued to operate a large engineering and home-maintenance network, while facing growing competition from smaller energy suppliers and changing regulation. It sponsored sports and entertainment properties, invested in service training and used commercial vehicle partnerships to support its field operations. The 2010s brought customer attrition, restructuring and pressure from the energy price cap. In 2016, the company reported a large loss of residential customers and announced the closure of an Oldbury office and call centre. Further customer losses and job reductions were announced in 2018 and 2019. In 2020, British Gas announced an ambition to replace diesel vans with an all-electric fleet by 2025, beginning with vehicles such as the Vauxhall Vivaro-e. The early 2020s were marked by a major labour dispute. In 2021, British Gas changed contractual terms for thousands of employees and required those rejecting the changes to leave. The policy generated public and political criticism, and workers undertook strikes between January and June. The dispute concluded when employees accepted a new pay deal. In 2023, British Gas attracted intense criticism over customer-service problems and reports that a contractor had entered homes to install prepayment meters. The company conducted an internal investigation and said it would discontinue use of the contractor. Ofgem's sector review that year identified moderate weaknesses in British Gas customer-service procedures. Despite these controversies and the loss of its leading electricity-supplier position to Octopus Energy in 2024, British Gas remained a major UK gas supplier and a large provider of household energy and maintenance services.
