Glow-worm - a brand you can rely on.

Decades of experience

A whole network by your side

Quality meets reliability

Made in Britain

Decades of experience

Glow-worm has been building reliable, highly efficient boilers and controls for almost 90 years, providing families across Britain with the warmth and hot water they need - when they need it.

Originally founded as The Glow-worm Boiler and Fireplace Co Ltd, we first started producing boilers in 1934 at the Derwent Foundry in Derbyshire, utilising the strong currents of the River Derwent to drive the manufacturing plant.

In 1966, we built an additional assembly facility in Belper to support the introduction and increased demand for domestic gas central heating boilers. We continue to remain close to our Derbyshire roots, with the Belper facility becoming home to Glow-worm's head office and manufacturing plant.

 

A whole network by your side

Service: made for you. Our exclusive network of installers maintains our high standards and provides the best possible service.

At Glow-worm, we know how important our installers are. With their expert product knowledge, our installers put all their energy into delivering the best possible service and highest standards. That’s why we support them, so that they can support you.

It’s this drive that has led us right to the top as one of the leading heating manufacturers in the UK today.

 

Quality meets reliability

Our goal: to make our customers' lives easier.

We're constantly improving our products to guarantee high quality, reliability and durability. But it's not just our products that you can rely on; our customer service is always at your side. So you can stay relaxed all year round.

This high-quality build and performance of our products has even earned us an ‘Excellent’ rating from our customers on Trustpilot.

 

Made in Britain

Did you know that some of Glow-worm's most popular boilers are manufactured in Britain at our Derbyshire factory? We have recently been accredited with ‘Made In Britain’ on our Energy, Ultimate and Easicom boiler range.

What is Made in Britain?

Made in Britain is an officially licensed mark bringing together the British manufacturing community. It is a not-for-profit organisation that helps to identify and certify British-made products.

 

Which Glow-worm boiler works for you and your home?

Glow-worm manufactures highly efficient boilers for all types of home:

Combination boilers

Combi boilers are a convenient all-in-one solution for smaller households with low hot water demands (such as one shower or bath), that would benefit from hot water almost instantly and a perfectly heated home.

 

System boilers

These boilers are fitted with a cylinder to provide steady hot water and a comfortable home temperature. These boilers are perfect if you have a high water demand from multiple sources at once.

 

Regular (open vent) boilers

Offering heating comfort and hot water for larger households with multiple bathrooms and high hot water demand.
