Learn moreWhat makes our boiler installs work different in South Street
Three things Bishop's Stortford 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.
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.
Everything we do is Gas Safe registered, fully insured, and backed by a 12-month workmanship guarantee.
About South Street
Older central Stortford street with period properties and conservation considerations.
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
