Boiler Repair Costs in Swindon (2026 Guide)
Repair pricing follows the part and the labour time, not the boiler's colour. Below are the public UK ranges that Swindon quotes will normally land inside.
Typical faults and indicative costs
| Fault | Typical part range | Notes |
|---|---|---|
| Fan failure | £150–£300 | Common on boilers 8+ years old |
| Diverter valve | £200–£350 | Hot water fails but heating works |
| PCB (circuit board) | £250–£500 | The expensive one; compare against replacement |
| Pump | £150–£300 | Often misdiagnosed as sludge |
| Pressure relief valve | £80–£200 | Usually accompanies pressure loss |
| Frozen condensate pipe | £0–£150 | Often preventable; see winter guide |
Add £80–£150 for call-out and diagnosis, which many engineers credit against the repair if you proceed.

Repair or replace?
A common industry heuristic: if the repair costs more than half a replacement, or the boiler is past 10–12 years old with repeated faults, replacement usually wins on economics — new boilers are significantly more efficient, and finance spreads the cost.
