Quick answers on heating upgrades in Ayot St Lawrence

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.

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.
