Common questions about heating upgrades in Sele Farm
How long does a quote take?▾
Most quotes go out within 24 hours of the survey, sometimes same-day if it's a straight swap.
Will you match other quotes?▾
We won't price-match for the sake of winning the job, but we will explain exactly what's included in our quote vs theirs — that's usually where the difference is.
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.
