When a boiler stops working in a Fulham home, the first worry is usually cost. Is it a small fault, an expensive part or the start of a bigger breakdown? At Kew Gas Boiler Repairs & Installation, we help SW6 homeowners and landlords understand real boiler repair prices before problems get worse. Early checks can often prevent higher costs, heating loss and emergency call-outs.
Common Boiler Repair Costs in Fulham SW6
Boiler repair costs depend on the fault, boiler brand and parts needed. Current UK price guides place most common boiler repairs between £100 and £500, while London boiler repair listings show an average of around £300. Emergency repairs cost more, averaging around £410 in London.
Typical prices include:
- Low pressure / minor fault repair: £80–£200
- Thermostat replacement: £120–£300
- Pump or diverter valve replacement: £200–£400
- PCB repair or replacement: £250–£550
- Heat exchanger replacement: £450–£750, with some faults reaching £1,200+ depending on the boiler model.
Modern boilers can cost more to repair because major parts such as PCBs, pumps and heat exchangers are brand-specific and often require specialist diagnosis.
Why Boiler Repairs Cost More Now
Repair costs can rise because of:
- Higher parts prices
- Labour charges
- Hard-to-find older boiler parts
- Complex electronic controls
A small leak, pressure fault or warning code can become expensive if left too long.
The Cost of Delaying Boiler Repairs
A Fulham landlord called Kew Gas Boiler Repairs & Installation after repeated pressure loss.
The fault was a failing expansion vessel. Early repair could have cost under £300. After delays, extra internal damage pushed the repair above £700.
This is common in older SW6 homes where small faults are missed.
