If your boiler is not working and you have no heating or hot water, do not panic. These quick checks may help you identify a simple issue before you call an engineer.
Quick checks when your boiler stops working
It can be frustrating when a boiler stops working, especially during colder months. Follow these basic checks before arranging a repair.
1. Check the gas supply
See whether another gas appliance still works. If it does not, your gas supply may be interrupted. Contact your supplier or follow the National Gas Emergency guidance if you suspect a leak.
2. Check the power
A power cut or tripped circuit can stop a boiler. Check the fuse box and make sure the boiler has power.
3. Check the boiler pressure
If the pressure is below the level recommended by the manufacturer, the boiler may shut down. Consult the appliance manual before repressurising the system.
4. Check for a frozen condensate pipe
In freezing weather, an external condensate pipe can freeze and cause a fault. Follow the manufacturer’s instructions before attempting to thaw or reset the appliance.
5. Try the manufacturer’s reset procedure
Many modern boilers have a reset function. Check the manual for the correct procedure, then wait to see whether the boiler restarts.
