Halma plc is a British global group of safety equipment companies that makes products for hazard detection and life protection based in Amersham, England. It is listed on the London Stock Exchange and is a constituent of the FTSE 100 Index.
The company was established in 1894 in Sri Lanka as The Nahalma Tea Estate Company Limited. It switched to rubber production in 1937 and became The Nahalma Rubber Estate Company Limited. During the early 1950s the company's rubber estates were nationalised by the Sri Lankan government, and in 1956 the company became Halma Investments Limited, thereby severing its connections with both tea and rubber and becoming an investment and industrial holding company.
Halma was co-founded by David Barber and Mike Arthur in 1972.
Halma share price listed on the London Stock Exchange in January 1972.
