About Thorley
South-west Stortford with strong post-war housing stock. Steady volume of boiler swaps.
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
Thorley homeowners trust us for heating upgrades — here's why
Our heating upgrades work in Bishop's Stortford is built around three things: doing it properly, charging fairly, and being there afterwards if you need us.
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.
If something plays up in the first year, we come back and sort it. No quibbles, no callout fee.
What's included
Power Flushing
Deep clean of central heating to remove sludge and restore efficiency.

Do you charge more on weekends?▾
Saturdays are charged at our standard day rate. Sunday emergency callouts carry a small uplift — we'll tell you the exact figure before you commit.
Can I book a routine service for a Saturday?▾
Yes — Saturdays are popular for services and CP12s, so book a couple of weeks ahead if you can.
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.
