About Old Harlow
The historic centre of Harlow with period properties pre-dating the new town. Conservation considerations affect external flue placement.
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

We've been doing boiler repairs in Harlow long enough to know which streets have shared chimneys, which estates have undersized gas supplies, and which boilers tend to fail first.
That experience means we get the spec right at the survey, not halfway through the install.
Diverter valve and PCB faults are particularly common across Harlow's older Worcester 24i and Vaillant ecoTEC units installed in the 2008–2014 boom.
