No heating or hot water?

Try these simple checks on your boiler before calling us.

Try these 6 simple steps to check your boiler before calling us.

  1. Step 1: fuse box, prepayment meter and gas hob

    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. Step 2: boiler timer

    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. Step 3: boiler pressure gauge

    Check the pressure

    If your boiler’s pressure gauge 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. Step 4: room thermostat

    Turn your thermostat up

    Turn your thermostat to 21 degrees or higher to see if your boiler starts working.

  5. Step 5: boiler and relight instructions

    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.
