Most straightforward swaps are completed in a day. We leave the job clean and show you how everything works before we go.

A recent boiler installation in Bow
A customer in Bow needed a new boiler and knew exactly what they wanted: another Glow-worm. Their previous Glow-worm had lasted over 15 years and they’d been happy with it, so they wanted the same trusted brand again. Before fitting the new boiler we power flushed the system to clear out years of built-up sludge (pictured) — protecting the new boiler and its warranty from day one — then installed the new Glow-worm and commissioned it. A great example of doing the groundwork properly, so a reliable brand gets the clean system it needs to last.
