About Katherines
Newer estate on Harlow's western edge with predominantly combi-boilered housing.
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 installations 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.
We do a steady stream of back-boiler removals across the original new town housing — the 1960s installations are now well past replacement age.
