About Sawbridgeworth
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 Sawbridgeworth customers pick us for heating upgrades

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.

Frequently asked questions — heating upgrades, Sawbridgeworth
Why don't you publish fixed prices online?▾
Because every job is different. The "from £1,499" you see on national sites almost never includes flue, system flush, controls, or any pipework changes — the bits that always come up.
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.
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.
