Where exactly are you based?▾

Are you a small team or a big firm?▾
Small family team. The person quoting you is the person doing the work — there's no sales rep, no sub-contracting, no call centre.
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.

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.
