Trusted for boiler installs across South Street
Our boiler installs work in Bishop's Stortford is built around three things: doing it properly, charging fairly, and being there afterwards if you need us.
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.
If something plays up in the first year, we come back and sort it. No quibbles, no callout fee.
About South Street

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
