UK manufacturing and history

Originally founded as The Glow-worm Boiler and Fireplace Co Ltd, the company began producing boilers in 1934 at the Derwent Foundry in Derbyshire, using the currents of the River Derwent to power the manufacturing plant. In 1966, it built an additional assembly facility in Belper to meet the growing demand for domestic gas central heating boilers. Today, the Belper facility is home to Glow-worm's head office and factory. Some of its most popular boilers are manufactured in the UK and have obtained the 'Made in Britain' certification for the Energy, Ultimate, and Easicom ranges.
