Quick answers on heating upgrades in Westmill
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.
