Boiler Repair Cost Kingston | Price Guide 2024

What affects boiler repair costs?

The main factors are the fault type, the parts required, the engineer's time and the urgency. A simple fix like a failed sensor is cheaper than replacing a heat exchanger or PCB. Emergency or out-of-hours callouts carry a premium.

Typical boiler repair price ranges

Minor repairs (e.g. faulty thermistor, pressure sensor): £80–£180 including parts. Mid-range repairs (e.g. diverter valve, fan, pump): £180–£350. Major component repairs (e.g. PCB, heat exchanger): £300–£500+.

Prices include labour, parts and VAT. Emergency callouts typically add £50–£100 to routine rates.

When is a repair not worth it?

If your boiler is over 12–15 years old and the repair exceeds roughly half the cost of a replacement, a new boiler may be more cost-effective — especially with energy savings from a modern A-rated unit.

We'll always give you an honest view and can quote for a replacement alongside the repair if it makes sense.

Frequently asked questions

Do you charge a callout fee?

We charge a fixed diagnostic fee that covers the callout and fault-finding. If you proceed with the repair, this is typically rolled into the total cost.

How do I get a quote?

Call us with your boiler make and model and a description of the fault, and we'll give you an estimate. For an exact quote, we'll confirm on-site before work starts.
