About High Wych
Rural village west of Sawbridgeworth. Off mains gas in places — LPG installs and conversions come up regularly.
Mix of period high-street properties, Victorian/Edwardian terraces, and modern executive estates around the station.
- Conservation area restrictions affect external flue siting on period properties
- Some streets have shared chimney stacks where flue routing needs coordination
- High Wych and rural fringes occasionally on LPG rather than mains gas
Why High Wych customers pick us for heating upgrades
We've been doing heating upgrades in Sawbridgeworth 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.
And we don't cut corners on the bits you can't see — proper pipework, magnetic filter, full system flush where needed.

Quick answers on heating upgrades in High Wych
Why has my heating stopped working?▾
Top causes: frozen condensate pipe in cold weather, low system pressure, a seized pump after summer dormancy, or a stuck motorised valve. Most are quick fixes once diagnosed properly.
Can I do anything before you arrive?▾
Check the boiler pressure (should be 1.0-1.5 bar cold). If it's below 0.5, top up using the filling loop. If you can hear the boiler firing but radiators stay cold, the issue is in the system, not the boiler itself.
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.
Will a smart thermostat actually save money?▾
Yes — typically 8–12% off heating bills if you use the scheduling and zone features properly. Hive and Nest both pay back inside two years for most households.
