Common questions about heating upgrades in Codicote
What's a fair price for this job in Codicote?▾
Pricing depends on the boiler, the existing pipework, and any system upgrades needed. We're typically 10-20% under the big national chains because we don't carry their overheads — and the workmanship is better.
Are quotes free?▾
Yes — quotes are always free, in writing, and there's no obligation. We don't do high-pressure sales.
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.
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.
