"Back-to-back terrace, boiler died on a Sunday morning. Engineer diagnosed the fan by lunchtime, sourced the part in Leeds and had heating back on before tea. £50 diagnostic came off the bill."

Boiler Repair in Leeds — £50 Fixed Diagnostic, Honest Quote

£50 diagnostic — refunded if we can't fix it
Typical repair band: £120–£320 for combi faults; student-let quick repairs £110–£240; system-boiler repairs £160–£380.
Fair fixed quote in writing before any work
What boilers in Leeds actually look like right now
Leeds student-belt terraces (Headingley, Hyde Park, LS6) have 12–18 year Baxi and Potterton combis worked hard by high-occupancy tenancies; the LS7–LS17 semi belt runs 6–12 year Worcester and Ideal Logic units.
Leeds boiler-repair work is heavily rental-driven in LS4/LS6 — Baxi and Potterton combis that need ignition packs, PRVs and expansion vessels rather than full swaps. Owner-occupier stock in LS7/LS16/LS17 leans toward proper diagnostic conversations on 8–12 year Worcester Greenstars.
Leeds water hardness & magnetic filter advice
Local hardness: Soft (typically 25–45 mg/L CaCO₃) — Yorkshire Water supplied largely from Pennine reservoirs.
Leeds is genuinely soft water (typically 30–50 mg/L). Scale is not the issue — magnetite and student-tenancy neglect are. A Magnaclean fit is the standard local recommendation on any repair.
The 5 boiler faults we see most in Leeds
- Baxi ignition lockouts in LS6 student lets
- Potterton PRV weeping on 15-year combis
- Worcester Greenstar diverter stuck (LS17)
- Ideal Logic F1 in Chapel Allerton
- Expansion vessel pre-charge loss on 10+ year Baxis
How Kevin approaches a boiler repair in Leeds
- For LS6 lets, quote the cheapest safe fix — landlords make swap decisions separately
- Carry Baxi ignition kits and Potterton PRVs on the van
- Fit a Magnaclean during the repair when the system runs black
- For LS17 Greenstars, give a proper repair-vs-replace opinion in writing
- Test flue seals and combustion on any 10+ year Worcester before ordering parts
Transparent repair cost band for Leeds
£120–£320 for combi faults; student-let quick repairs £110–£240; system-boiler repairs £160–£380.
Every price is confirmed in writing after the £50 diagnostic. Nothing billable starts until you approve the fair fixed quote — and if we can't fix the fault we diagnosed, the £50 is refunded.
Why you shouldn't be sold a new boiler in Leeds without a proper diagnosis
A common LS6 landlord scam is "your rental Baxi needs replacing, £2,600". If a landlord's boiler is throwing an ignition code it's a £180 electrode, not a £2,600 swap — get a second opinion before signing.
Our promise on every Leeds 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.

Recent Leeds customer reviews
"HIU in a Candle House apartment was giving intermittent hot water. Two other plumbers had walked away. KJ knew exactly what a Danfoss looked like — cleaned the strainers, replaced a sensor, sorted."
— Marcus J., Granary Wharf · HIU repair, Leeds city centre
"1930s semi, upstairs rads always cold. Proper diagnosis, magnetic filter fitted and a light flush — didn't oversell a full power flush. Refreshing."
