Gas Light and Coke Company

The Gas Light and Coke Company (also known as the Westminster Gas Light and Coke Company, and the Chartered Gas Light and Coke Company), was a company that made and supplied coal gas and coke. The headquarters of the company were located on Horseferry Road in Westminster, London. It is identified as the original company from which British Gas plc is descended.

The company was founded by Frederick Albert Winsor, who was originally from Germany, and incorporated by Royal Charter on 30 April 1812 under the seal of King George III. It was the first company set up to supply London with (coal) gas, and operated the first gas works in the United Kingdom which was also the world's first public gas works. It was governed by a "Court of Directors", which met for the first time on 24 June 1812. The original capitalisation was £1 million (about £9 billion at 2005 prices), in 80,000 shares.

Offices were established at Pall Mall, with a wharf at Cannon Row. In 1818 the company established a tar works in Poplar and expanded their works at Brick Lane and Westminster. Under the company's chief engineer, Samuel Clegg (formerly of Boulton and Watt), a gas works was installed at the Royal Mint in 1817 and by 1819 nearly 290 miles of pipes had been laid in London, supplying 51,000 burners. Clegg also developed a practical gas meter.
