No heating in the middle of winter? Boiler showing an error code? Gas smell? Our Gas Safe engineers are on call around the clock to diagnose and repair your boiler — most faults are fixed on the first visit.
Immediate Advice
Before our engineer arrives, run through these quick checks — they can sometimes resolve the issue or help us diagnose it faster.
Most combi boilers need pressure between 1 and 1.5 bar. If it's dropped below 1, your boiler may have locked out. We can talk you through repressurising over the phone.
Most boilers have a reset button (often marked with a flame or power icon). Press and hold for 3–5 seconds. If the boiler fires up, monitor it — recurring lockouts need investigating.
Make sure your room thermostat is set above the current room temperature and that the timer/programmer is set correctly. Dead batteries in wireless stats are a common culprit.
Open windows immediately, don't touch light switches or electrics, get everyone outside, and call the National Gas Emergency line on 0800 111 999. Then call us.
Common Causes
Boilers fail for a range of reasons. Knowing the symptoms helps us arrive with the right parts.
The condensate pipe runs outside and can freeze in cold weather, causing the boiler to lock out. This is the single most common winter callout.
If the internal pump or fan stops working, the boiler can't circulate water or expel flue gases safely, and it shuts down as a precaution.
This valve switches between heating and hot water. When it sticks or fails, you might have heating but no hot water — or vice versa.
The printed circuit board is the boiler's brain. Electrical faults, failed ignition leads, or flame sensor issues can all trigger error codes and lockouts.
A slow leak in the heating system causes gradual pressure loss. The boiler drops below its operating range and locks out for safety.
Our Response
We read the error code, run diagnostic tests, and identify the root cause — not just the symptom.
You get a clear explanation of the fault and a fixed price for the repair before we start any work.
Most common parts are carried on our vans. The majority of boiler repairs are completed on the first visit.
The boiler is fully tested across heating and hot water modes. All work comes with a 1-year guarantee.
