About Bishop's Stortford
Strong mix — Victorian terraces in the old centre, post-war housing in Thorley, and large new-build estates expanding north.
- New-build combi boilers approaching first major service interval
- Victorian terrace flue routing constraints
- Hard water from the chalk aquifer accelerates scale build-up in heat exchangers
Why Bishop's Stortford customers pick us for boiler installs
We've been doing boiler installations in Bishop's Stortford 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.
Hard water in CM23 means we strongly recommend a magnetic filter and limescale inhibitor on every install — heat exchanger failures from scale are common after 4–5 years without one.
