If you can smell gas, treat it as an emergency. Turn off the gas supply if safe, open windows/doors, avoid electrical switches, and call the National Gas Emergency line.

If there’s water leaking near electrics, isolate power if safe and avoid touching wet switches/sockets.

• Pressure: note the gauge reading (many systems run around ~1.0–1.5 bar when cold).
• Fault code: take a photo of the display.
• Condensate: in freezing weather, a frozen condensate pipe is common.
• Timer/thermostat: confirm heating is “on” and set above room temp.

• Boiler make/model (if you know it)
• What’s happening (no heat/no hot water/leak/noise/fault code)
• Any recent work or changes
• Your postcode (helps with fastest routing)

Some faults can be fixed quickly, but repeated breakdowns may indicate underlying issues. If you want preventative protection, explore breakdown cover plans or consider a boiler service.

Common causes include pressure issues, diverter valve faults, ignition problems, frozen condensate pipes, sensor issues and more.

We diagnose the issue, explain the fix clearly, and help you decide the best next step—repair, service, or replacement.

Often linked to leaks, faulty components or expansion vessel issues. We’ll identify the cause and advise on the correct repair.

If you’d rather spread costs, our breakdown cover plans include priority call-outs and ongoing protection (excess applies).
