Things Ayot St Lawrence customers usually ask about heating upgrades
What's a fair price for this job in Ayot St Lawrence?▾
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.
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.
