If your boiler stops working, one of the first questions is usually how much it will cost to put right.
Boiler repair costs can vary depending on the fault, the age and model of the boiler, and whether parts need to be replaced. Emergency call-outs outside normal working hours can also increase the final price. This guide gives a general idea of typical boiler repair costs and explains when it may be better to repair a boiler and when replacement could make more sense.
Typical Boiler Repair Costs
For many common boiler faults, repair costs often fall between £100 and £400. Simpler problems can sometimes be resolved quickly, while more serious faults may involve extra labour or replacement parts.
If the repair is needed urgently, especially in the evening, at weekends, or during cold weather, the total cost may be higher.
Typical Prices for Common Boiler Problems
| Boiler Problem | Typical Cost |
|---|---|
| Thermostat replacement | £80–£150 |
| Boiler pressure fix | £90–£150 |
| Pump repair or replacement | £150–£300 |
| Diverter valve replacement | £120–£250 |
| Heat exchanger repair | £300–£600 |
These figures are only a general guide. The final cost will depend on the boiler brand, the parts required, and how straightforward the repair is.
Emergency Boiler Repair
A boiler breakdown can become urgent very quickly, especially during winter or when you have no heating or hot water. In these situations, many heating engineers offer emergency boiler repair services to diagnose the fault and restore the system as soon as possible.
Emergency call-outs usually cost more than standard appointments, particularly outside normal working hours.
When Repair Might Be Enough
In many cases, a repair is the simplest and most cost-effective option, especially if the fault is minor and the boiler is otherwise working well. Problems such as low pressure, thermostat issues, or a faulty pump can often be repaired without needing to replace the whole system.
A qualified heating engineer can inspect the boiler, identify the cause of the fault, and advise on the best next step.
When Replacement May Be the Better Option
Sometimes, repairing a boiler is not the best long-term decision. Replacement may be worth considering if:
– the boiler is around 10 to 15 years old or older
– faults are becoming more frequent
– replacement parts are difficult or expensive to source
– the boiler is losing efficiency and running costs are increasing
If repair costs start to add up, replacing the boiler may offer better value over time.
