Who Is Glow-worm?

Glow-worm Boiler Prices & Review Compare Boiler Quotes

Glow-worm is a UK-based boiler manufacturer that has been in operation since 1934. With facilities in Derbyshire, Glow-worm is one of the only brands in the market to develop its products inside the UK.

In 1992, Glow-worm claimed to have possessed around 40% of the heating industry’s market share, whilst also being the first company to popularise the condensing boiler.

In 2001, Glow-worm was acquired by then competitor Valliant, providing Glow-worm with an even larger competitive advantage in the industry.

Although Glow-worm’s popularity has dwindled in recent years, its products are still regarded as being some of the best available.

What Boilers Does Glow-worm Manufacture?

Much like its competitors, Glow-worm offer an extensive range of regular, combi and system boilers in various configurations. Many of them come with long warranty periods of up to seven years, in addition to Quiet Mark certifications due to their low noise.
