Why we're a sensible choice for boiler installs 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.
