In 1886 the company, which had dropped the "Light" from its name, began using the carbureted water gas process to manufacture gas.

Notwithstanding attempts by the Emergency Scientific Research Bureau to manufacture gas from bog peat, imports of suitable coal and therefore gas production fell dramatically and initially its use for home heating was prohibited.

Before natural gas grew in popularity, these sites were used to manufacture gas.

The first attempts to manufacture gas in a commercial way were made in the period 1795-1805 in France by Philippe Lebon, and in England by William Murdoch.

Fairbanks Morse Engine manufactures heavy-duty, medium speed diesel, natural gas and dual-fuel reciprocating engines.

Technetics Group manufactures engineered seals, components, assemblies and sub-systems that are designed for high-performance or extreme applications in the semi-conductor, aerospace, power generation, nuclear, oil and gas, medical and pharmaceutical industries.

Originally manufacturing gas from coal, the plant began to manufacture gas from oil in the 1960s.

In 1895, the company added gas engines to its product line, and would continue to manufacture gas and steam until the latter was discontinued following World War II.

It came eventually to manufacture gas for most of London north of the Thames, with numerous smaller works being closed.

The existing gas storage infrastructure would allow the plant to continue to manufacture gas at the full utilisation rate even during periods of weak demand, helping minimise manufacturing capital costs per unit of gas produced.
