Learn moreWhat makes our boiler installs work different in The Stow
Three things Harlow customers tell us they value: we turn up when we say we will, we explain things in plain English, and we don't try to sell you anything you don't need.
We do a steady stream of back-boiler removals across the original new town housing — the 1960s installations are now well past replacement age.
Everything we do is Gas Safe registered, fully insured, and backed by a 12-month workmanship guarantee.
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
What you get when you book us
- Old boiler removed and disposed of properly
- Gas Safe registered (reg. number on every quote)
- Boiler registered for warranty on the day
- Worcester Bosch Accredited Installer
- 5-star reviews on Google & Checkatrade
Common questions about boiler installs in The Stow
