Glow-worm boiler repair and servicing across London

About Glow-worm

Glow-worm is the value range in the Vaillant group. It’s been going into UK homes for decades, so the boilers out there span many generations. In London, they often turn up where a boiler was swapped on a tight budget rather than chosen with care. Landlord-owned flats are another common spot.

Faults we often find on a Glow-worm

• Older boilers reaching the point where repairs stop making sense
• Diverter and pressure faults, typical for boilers of this age
• Cheapest-option replacements fitted in an awkward or unsuitable spot

This is what tends to crop up, not a verdict on yours. An engineer checks your boiler in person and finds the fault before giving you a price.

Asked about Glow-worm

Are Glow-worm and Vaillant the same thing?

They’re in the same group but sold as different ranges. Glow-worm is the value option and Vaillant the premium one. The products aren’t identical and not every part is shared. Both are well supported, though, so neither will leave you stranded.

Can you fix and service my Glow-worm?

We can. Our gas work is done by Gas Safe registered engineers. By law, that is what any gas boiler needs, whatever the make.
