The prices on this page are typical UK market prices, not our price list and not a quote.

You can verify the engineer's individual Gas Safe registration on arrival.
What affects the cost of a boiler repair?
A Birmingham boiler repair bill depends on several things, not just the fault itself.
- The specific fault and the part it needs
- How long the job takes to complete
- Your boiler type: combi, system or conventional
- The age and brand of your boiler, and how easy the part is to source
- Whether it is an emergency or an out-of-hours job
- How easy the boiler is to reach
If the fault turns out to be more about years of neglect than a single failed part, your engineer may recommend a full boiler service instead of a repair.
Boiler repair cost by fault (2026)
The table below shows typical UK market prices for common faults, including parts and labour. They are a guide to what Birmingham homeowners can expect, not our prices. The diagnostic call-out fee is separate unless stated, and older or less common boilers sit at the higher end.
| Fault | Typical UK price (parts and labour) | Notes |
|---|---|---|
| Low pressure fix or repressurising | £80 to £150 | Plus cost of re-pressurise and system check |
| Leak repair | £100 to £250 | |
| Thermostat replacement | £100 to £200 | Simple part, low labour time |
| Diverter valve | £200 to £350 | Common combi boiler repair |
| Expansion vessel | £120 to £250 | |
| Circulation pump | £200 to £400 | Varies by model and access difficulty |
| Fan assembly | £150 to £350 | |
| Gas valve | £200 to £450 | Gas Safe engineer required |
| Printed circuit board (PCB) | £250 to £500 | Part cost varies significantly by brand |
| Heat exchanger | £400 to £650 or more | Expensive, consider age of boiler |
How much is a boiler engineer call-out fee?
At typical UK market prices a diagnostic call-out costs £60 to £90, and some engineers deduct it from the repair bill if you go ahead. Gas Safe engineers charge roughly £50 to £80 per hour for labour on top of parts. Ask about the call-out charge before the visit is booked.
How much does an emergency boiler repair cost?
Emergency and out-of-hours repairs usually add an urgency fee, often £50 to £150 on top of the standard price at typical UK market rates. Emergency jobs average around £450 and can reach roughly £650 depending on the fault and the time of day. See our emergency boiler repair page for what counts as an emergency.
Is it cheaper to repair or replace my boiler?
For most single-part faults, repairing is far cheaper than a full replacement, which runs £1,500 to £5,000 fitted. The main exception is a failed heat exchanger on an older boiler, where the repair cost gets close to replacement and a new boiler can make more sense.
How do you read a boiler repair quote?
A good quote tells you what has failed, what will fix it and what each part of the price is for. Check that it includes:
- The fault named in plain terms, for example "diverter valve sticking", not "boiler playing up"
- The part being replaced, ideally with the part name or number
- Parts and labour shown separately, and whether the call-out fee is included or deducted
- Whether VAT is included
- Any warranty on the part and on the labour
- What happens if the repair does not cure the fault
Be wary of a jump straight to replacing the whole boiler for one inexpensive part, and of a price that only arrives after the work is done. A second opinion costs one call-out and can save a lot. If you are not sure what the fault is yet, the common boiler faults guide explains the usual causes behind each symptom and fault code.
