Learn moreLocal, honest heating upgrades for Thorley homes
We've been doing heating upgrades 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.
Power flushes pay for themselves quickly here because of the hard water — we typically pull out a kilo of black sludge from a 10-year-old system.

Quick answers on heating upgrades in Thorley
What's a fair price for this job in Thorley?▾
Pricing depends on the boiler, the existing pipework, and any system upgrades needed. We're typically 10-20% under the big national chains because we don't carry their overheads — and the workmanship is better.
Are quotes free?▾
Yes — quotes are always free, in writing, and there's no obligation. We don't do high-pressure sales.
Do I really need a power flush?▾
If radiators have cold patches, your boiler is noisy, or you're fitting a new boiler to an older system, yes. Otherwise a chemical flush and magnetic filter is often enough.
How much does a power flush cost?▾
Typically £450–£750 depending on system size and number of radiators. We give a fixed price after a quick survey.
