"Combi swap in a two-up two-down, needed the gas run upsized and boxed. KJ took the time to plan the route so it didn't dominate the kitchen. Great job."

What boilers in Accrington actually look like right now
Accrington and Oswaldtwistle stone terraces run 12–18 year Baxi, Potterton and Ideal Icos combis; newer estates in Great Harwood carry 6–10 year Worcester and Vaillant units.
Accrington boiler-repair work is dominated by Baxi ignition faults, Potterton PRV weeping, and Ideal Icos low-pressure lockouts. We keep the parts on the van for all three.
Accrington water hardness & magnetic filter advice
Local hardness: Soft (30–50 mg/L CaCO₃) — Pennine reservoir supply.
BB5 water is moderate-hard (140–180 mg/L). Magnaclean plus scale reducer on any combi repair without protection is the honest call.
