About British Gas

With a company history going back to 1812, their founding company was the Gas Light and Coke Company which operated until 1948 when it then formed a major part of the New North Thames Gas Board.

The Gas act of 1972 resulted in the merger of all the local area Gas boards which created the British Gas Corporation.

In 1986 the then Conservative government prime minister, Margaret Thatcher introduced the Gas Act 1986 which privatised the company with shares floated on the London Stock Exchange on December 8th, 1986.

British Gas Services Limited is one of the companies that was formed when British Gas PLC De-merged in 1997, 11 years after it had been privatised and is now part of Centrica.
