Things Great Amwell customers usually ask about heating upgrades
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.
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.
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.
