Things Loughton customers usually ask about heating upgrades
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.
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.
