Boiler Repair in Burnley — £50 Fixed Diagnostic, Honest Quote
In short
Burnley boilers age fast — the water sees to that. My typical BB11 diagnostic starts with a torch on the plate exchanger, not the display code.
Response: 85–120 minutes across BB10, BB11, BB12
£50 diagnostic — refunded if we can't fix it
Typical repair band: £130–£340 for combi faults; Kamco descale £180–£240; system-boiler repairs £160–£380.
Fair fixed quote in writing before any work
What boilers in Burnley actually look like right now
Burnley stone terraces run older stock — 12–20 year Baxi, Potterton and Ideal Icos combis are common. Newer Padiham and Rose Grove estates have 6–10 year Worcester and Vaillant units.
Burnley boiler-repair work is defined by hard water: scaled plate exchangers, blocked expansion vessels, PRVs weeping from scale-cracked seats. We descale rather than replace, and we fit scale reducers on every repair on unprotected combis.
Burnley water hardness & magnetic filter advice
Local hardness: Soft (25–45 mg/L CaCO₃) — Pennine reservoir supply.
Burnley water hardens sharply — BB10/BB11 see 180–220 mg/L. Every combi repair here should be quoted with an inline scale reducer, not just a Magnaclean.
The 5 boiler faults we see most in Burnley
- Scaled plate exchanger (all hard-water combis)
- Baxi ignition failure
- PRV weeping from scale damage
- Expansion vessel pre-charge loss (scaled)
- Ideal Icos low-pressure lockouts
How Kevin approaches a boiler repair in Burnley
- For BB10/BB11, treat plate-exchanger scaling as the default HW-fade diagnosis
- Quote a scale reducer on every combi repair without one
- Descale on-site with Kamco rather than swapping exchangers
- Test expansion vessel pre-charge on every hard-water repair
- For 15+ year units, give a written replace opinion with real numbers

Why you shouldn't be sold a new boiler in Burnley without a proper diagnosis
Burnley customers get "your boiler is scaled beyond repair" verdicts that are almost never true. Descale is a 90-minute job — insist on it being attempted before you agree to a £2,500 swap.
Our promise on every Burnley 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.

"Talked us out of ditching the cylinder in favour of a combi. New system boiler, cylinder retained, showers on both floors now actually work at once."
