A brief history of Brannan


Brannan was founded by Sydney Brannan, a thermometer maker in south London, who created the Company back in 1913, when he identified an opportunity in the manufacturing market for the production of glass medical thermometers.


Brannan expanded production to make thermometers for industrial and scientific markets.


The company was incorporated.


During World War II, manufacturing was relocated to Cleator Moor in Cumberland (Cumbria) and the company expanded to supply thermometers to hospitals, to industry and to the Navy.


After the war, industrial and scientific products were in great demand and the company doubled production in two years.


A large investment in automated glass working machinery reduced production costs significantly allowing the company to start selling successfully around the world as well as our expanding industrial and retail markets in the UK.


Brannan entered foreign markets of South Africa, Singapore and Australia.


Brannan pioneered an off the shelf range of instruments for the plumbing market and expanded sales in the USA and Europe.


Brannan acquired a Swedish instrument manufacturer and started manufacturing pressure gauges sold to the expanding markets of Asia.


Brannan developed a calibration and testing laboratory to serve increasing customer demand for high accuracy products.


 A range of non-mercury products was launched alongside a campaign to educate our customers in the environmental advantages of these products.


Brannan focused on expanding industrial sales in the GCC region and other emerging markets.


 Brannan supplied medical thermometers to hospitals and care homes during the Coronavirus outbreak.
