Boiler Repair in the UK — Find a Local Gas Safe Engineer
Boiler repair by a Gas Safe registered engineer
A broken boiler always seems to happen at the worst possible time — a freezing morning with no hot water. BoilerFinder UK helps you find a local, Gas Safe registered engineer who can diagnose and fix the problem quickly and safely.
Signs your boiler needs repairing
- No hot water or heating, or only one of the two
- The boiler keeps switching itself off or losing pressure
- Banging, gurgling or whistling noises
- A fault or error code on the display
- Leaks, drips or a pilot light that won't stay lit
- Radiators that stay cold even when the boiler is on
What a boiler repair involves
A qualified engineer will first diagnose the fault — checking pressure, the flue, the gas supply, the pump, valves and electronics. Once the cause is found, they'll give you a price before carrying out the repair, replacing any faulty parts and testing the boiler is running safely before they leave.
How much does boiler repair cost in the UK?
As a rough guide, a call-out and diagnosis usually costs around £50–£90, and most repairs come to £100–£300 depending on the fault and the parts needed. Always ask for a fixed quote before work begins. If your boiler is old and breaking down often, an engineer may advise that a replacement is more cost-effective.
