Emergency Checklist

  1. Check the basics - do you have a prepayment meter? If you do, check that you've got enough credit. Are your other gas appliances, such as your cooker hob working? Have the switches in your fuse box tripped?
  2. Have you had a power cut recently? - If you have, the timer on your boiler may have reset. Re-programming it could solve the issue. Have a look at your instruction manual, or visit the manufacturer's website, for instructions on how to do this.
  3. Check the pressure - if your boiler's pressure guage is at one bar or less, low pressure could be the issue. Your boiler's manual will tell you how to top up the pressure.
  4. Turn your thermostat up - turn your thermostat to 21 degrees or higher to see if your boiler starts working.
  5. Reset your boiler - if your boiler was installed before 2004 it will probably have a pilot light. Check that this hasn't gone out. If it has, refer to the boiler's manual to see if you can relight it. For newer boilers, check the instructions for resetting it.
