Boiler Not Working


If your boiler’s stopped working, don’t worry – you may be able to fix it yourself. Try these safe and simple solutions to potentially get it back up and running without calling an engineer.

Double Check The Basics

First of all, if you have a prepayment meter, check that you’ve got enough credit. Next, test whether your other gas appliances, like your cooker hob, are working correctly, or whether the switches in your fuse box have tripped.

Turn Up Your Thermostat

Having your room thermostat set lower than 21 degrees can stop your heating from coming on, so turn it higher to see If your boiler starts working again.

Had A Recent Power Cut

If you have, your boiler’s timer might have reset – which means getting it working again could be as simple as re-programming it with your times. Take a look at its instruction manual for a reminder on how to do this.

Check Your Boiler's Pressure

If it’s showing a reading of one bar or less, low pressure could be the reason why your boiler’s not working. Topping up the pressure yourself is usually straightforward – follow the steps in your boiler’s manual.

Reset Your Boiler

Finally, try resetting your boiler according to its instructions. If yours was made pre-2004 it’s likely to have a pilot light instead of a reset function, so check that the pilot light is on. If it’s not, you may be able to relight it yourself according to its manual.
