Things High Wych 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.
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.
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.
