"Filling loop was hidden behind the kitchen carcass, isolators unlabelled. KJ found it, extended it neatly and labelled the whole plant room. Small job, huge relief."

What boilers in Chorley actually look like right now
Chorley's new-build estates (Buckshaw Village, Astley Village) run 5–10 year Worcester and Ideal combis; older Adlington and Coppull stock has 12–16 year Baxi and Potterton units.
Chorley boiler-repair work leans toward Worcester Greenstar diverter faults in Buckshaw Village new-builds, and Baxi/Potterton ignition and PRV faults in older Adlington and Coppull terraces. We keep both parts loadouts on the van.
Chorley water hardness & magnetic filter advice
Local hardness: Slightly hard (70–120 mg/L CaCO₃) — United Utilities blended supply.
Water is moderate hardness. Magnaclean standard on every repair; scale reducer sensible in the older PR7 terraces.

Why you shouldn't be sold a new boiler in Chorley without a proper diagnosis
New-build Buckshaw owners get quoted for warranty-voiding fixes by non-Gas-Safe engineers. If a Worcester is under manufacturer warranty, the repair must be Gas-Safe registered and OEM-parts — anything else voids the warranty.
Our promise on every Chorley boiler-repair call-out: £50 to attend and diagnose, a fair fixed quote in writing before any billable repair starts, and the £50 refunded if we can't fix the fault.
