About The Stow
Original new-town neighbourhood centre. Many original 1960s flats with undersized gas supplies that we've upgraded over the years.
Predominantly 1950s–70s post-war housing with a mix of terraces, semis, and 60s-built flats. Pockets of older stock around Old Harlow.
- Original 1960s flats often have undersized gas supply pipes that limit modern combi performance
- Older Old Harlow properties frequently have low mains water pressure that affects combi choice
- Many 60s/70s back boilers still in service — our regular work involves removing these and reinstating fireplaces
The Stow homeowners trust us for boiler servicing — here's why
Our boiler servicing work in Harlow is built around three things: doing it properly, charging fairly, and being there afterwards if you need us.
That last bit matters — a lot of installers vanish the moment the invoice clears. We don't.
If something plays up in the first year, we come back and sort it. No quibbles, no callout fee.

Learn moreCommon questions about boiler servicing in The Stow
Are Glow-worm and Vaillant the same?▾
Same parent group, often shared componentry, but Glow-worm sits at a lower price point with shorter warranties. Good value for rental properties.
How long does a service take?▾
Usually 45–60 minutes for a domestic boiler in normal condition.
How often should a boiler be serviced?▾
Once a year. It's almost always required to keep the manufacturer's warranty valid, and it catches small issues before they become breakdowns.

- Warranty paperwork preserved
