Centrica plc is a British multinational utility company with its headquarters in Windsor, Berkshire. Its principal activity is the supply of electricity and gas to businesses and consumers in the United Kingdom, the Republic of Ireland and North America. It is the largest supplier of gas to domestic customers in the UK, and one of the largest suppliers of electricity, operating under the trading names Scottish Gas in Scotland and British Gas in England and Wales. It owns Bord Gáis Energy in the Republic of Ireland. It is also active in the exploration and production of natural gas; electricity generation; and the provision of household services including plumbing.

Centrica is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.


Historical Origins

The company has its historical origin in the Gas Light and Coke Company which incorporated in 1812. Over the next 137 years it grew by acquisition of other gas companies to become the primary supplier of gas to Greater London. In 1949, under the Gas Act 1948 the ownership of the company transefered to a government agency, North Thames Gas Board.[2] The Gas Act 1986 sold the company to private investors as British Gas plc.[3]


Centrica became a separate, distinct corporation on 17 February 1997, when British Gas plc split (demerged) to form three separate companies: Centrica plc, BG plc and Transco plc. Centrica took over gas sales and gas trading, services and retail businesses, together with the gas production operations in the North and South Morecambe gas fields (Rampside Gas Terminal).[4]

In 1998, Centrica’s supplier monopoly for gas came to an end. Centrica maintained the British Gas retail brand but is only allowed to use this brand name in the UK. The electricity market also opened up to competition and, through the British Gas brand, the company started supplying its first domestic electricity customers.[5]

1998 to 2010

In late 1998, under CEO Sir Roy Gardner and Finance Director Mark Clare, Centrica attempted to diversify – firstly by developing the Goldfish credit card,[6] then in 1999 by acquiring the AA for £1.1 billion.[7] In 2000 Centrica further diversified with the opportunistic purchase of OneTel in the UK, a residential telecoms operator.[8] Soon afterwards Centrica acquired the Dyno franchise group (best known for its Dyno-Rod drains unblocking service).[9] Centrica also moved into the North American energy-supply market through the acquisition of the Canada-based company Direct Energy in 2000 for £406 million.[10] Direct Energy's operations were subsequently considerably expanded through a number of further acquisitions, including of Enbridge Services for £437 million in January 2002.[11]

This strategy of diversification changed in mid-2003, possibly under pressure from major city shareholders to deliver better returns and/or possibly anticipating pressure on the core UK energy supply business. The change of strategy started with the sale of the Goldfish business to Lloyds TSB Bank[12] (who subsequently sold it to Morgan Stanley Bank International Limited).[13] Then in 2004 Centrica sold the AA to two private equity firms; Luxembourgish CVC and British Permira for £1.75 billion.[14] Then in 2005 Centrica sold their OneTel business to Carphone Warehouse.[15]

Since 2005 Centrica has declared a strategy of consolidating within the energy sector, upstream and downstream, including expanding operations overseas. New chairman Roger Carr replaced retiring chairman Sir Michael Perry in 2005, whilst new CEO Sam Laidlaw picked up the reins from retiring CEO Sir Roy Gardner in 2006.[16]

In January 2006, it was rumoured that the Russian state-owned utility company Gazprom was seeking a takeover of Centrica. This created controversy in the media, while the Department for Trade and Industry stated any deal would be subject to "intense scrutiny". Tony Blair announced in April that he would not block any potential deal.[17]

In September 2008 the Company acquired the Caythorpe gas-producing field near Bridlington to use for storage purposes.[18] It also agreed to buy 20% of British Energy from EDF, financing this with a £2.2 billion, 3 for 8 rights issue.[19][20] The rights issue offered shares at 160 pence per share and closed on 12 December 2008.[21]

In August 2009, Centrica took over Venture Production, a North Sea gas producer.[22]

2010 to present

On 17 November 2010, Centrica acquired the assets of heat pump installation company Cool Planet Technologies Ltd. for £0.5 million in cash. This will give a boost to company’s strategy of developing a broad range of low carbon technologies and advice.[23]

In February 2011 Centrica signed a £2 billion three-year contract with Qatargas for the purchase of 2.4 million tonnes a year of liquefied natural gas.[24] In March 2011 Centrica agreed the sale of the electricity and gas supply business of its Netherlands-based subsidiary Oxxio to Eneco BV for €72 million (£63 million) in cash.[25] The sale completed Centrica's exit from the supply of electricity and gas in Continental Europe, following the earlier disposal of its supply businesses in Belgium and Spain.[25]

In November 2011, Centrica agreed to buy $1.6 billion stakes of 8 fields on the Norwegian continental shelf from Statoil ASA. In a second deal, Centrica agreed to buy 5 billion cubic meters a year gas from the same company from 2015 to 2025 as equal to 5 percent of UK gas consumption.[26]

Centrica's Germany-based trading division Centria Energie GmbH was closed in April 2012.[27]

In July 2013, it was announced that Centrica would acquire the energy marketing unit of Hess Corporation for $1.03 billion.[28]

In March 2014, Centrica acquired the retail arm and other assets belonging to Ireland’s state-owned Bord Gáis for a fee of around €1.1 billion.[29]

In 2010, Centrica entered into joint venture arrangements with Tullow Oil to explore for oil in the South Lokichar Basin in Kenya. In August 2014, Tullow, the operator, revealed significant oil discoveries had been made in the Etom 1 exploration well and testing block 10BB, which expanded the already proven South Lokichar Basin "significantly northwards," taking in an additional 247sq km.[30]


Centrica's operations are principally focused on the supply of electricity and gas to businesses and consumers in the United Kingdom and North America. Centrica Energy also generates electricity in the United Kingdom and has gas exploration and production operation in Norway. Centrica has some back office functions located in India and South Africa.

In 2009, Centrica purchased a 20% stake in nuclear power generator British Energy from EDF Energy. The company now produces 14.3% of its electricity from nuclear (the second highest rate in the UK), helping it to achieve the lowest carbon emissions of the major providers.[33] Centrica has also acquired an option to purchase a 20% stake in EDF's subsidiary, NNB Generation Company (NNB GenCo).[34]

Senior management

Sam Laidlaw was the chief executive of Centrica between 1 July 2006 and 31 December 2014. In the 2010 financial year Laidlaw received a total compensation of £1,841,000 from Centrica, comprising a salary of £941,000 and a bonus of £900,000.[35]



British Gas was accused of greenwashing in the advertising of its Zero Carbon tariff in 2008 after the Advertising Standards Association upheld a complaint about the 'greenest domestic tariff' claim.[36]

Customer complaint response

In July 2011, British Gas was fined £2.5 million by the energy regulator Ofgem for failing to deal properly with customer complaints.[37] After a year-long investigation into the British Gas, Ofgem found it had breached regulations on how energy companies should handle disputes. Ofgem found that British Gas failed to re-open complaints from customers who indicated they felt the matter was not resolved adequately, failed to provide sufficient information to complainants about the energy ombudsman service, and failed to deal properly with complaints from micro-businesses because it had not implemented the necessary processes and practices.[37]

A spokesperson for British Gas said the company felt that finding it in breach of rules for failing to provide adequate information to consumers about the energy ombudsman was "disproportionate to the mistake".[37]

British Gas Business was fined £1 million in July after Ofgem's investigation found the company had misreported the amount of electricity supplied under the British government's renewables obligation.[37] British Gas claims it spotted the problem – it said an over-reporting of the amount of renewable energy it was supplying caused by human error – and notified the regulator.[37]

Political activity

Centrica has entered the political arena by threatening an investment strike in response to the Labour Party's proposal for a price freeze. Caroline Flint, the shadow energy secretary, said: "It is not acceptable for companies to threaten that the lights will go out because they don't want greater transparency, competition and accountability".[38]
