Problem with your heating?

Before reporting a repair, please try the following:

  • Double check that the gas, electrical and water supplies to your appliance are turned on – somebody could have accidentally turned them off. An indicator light or a digital display on the boiler should be visible if electricity is supplied. If this isn’t the case, check the fuse.
  • Use the reset button on your boiler to reset it.
  • Try kickstarting your boiler back into action by putting your central heating on maximum for a short while.
  • Look at the display to see if there’s a fault code. If there is, look at the manufacturer’s instructions/user manual or use the internet to establish what the fault means and if there’s an easy fix. Only attempt fixing the fault if you feel confident.
  • Check that the thermostat is turned up and the clock timer is on. You might need to change the battery if it’s not hard-wired.
  • Some combi and system boilers have a pressure gauge showing system water pressure – this usually needs to be at around 1 bar. It’s easy to repressurise the boiler by following some simple instructions set out in the user manual – these will also be available on the manufacturer’s website. Never overfill a boiler as this will cause further problems. We have produced a handy video guide to repressurising your boiler.
  • Never attempt to repair a gas pipe or take the cover off a boiler. Only gas-safe registered engineers are permitted to work on gas installations and boilers.
  • Do you have a boiler system with a permanent pilot light? Check that it hasn’t gone out – this is a very common issue with older boilers.
  • Have the clocks gone forward or back? Your clock programmer might need adjusting to the right time.
  • Has there been a power cut and a break in the energy supply? Your heating clock programmer has potentially been reset back to the original factory settings. Test the central heating by setting it to come on in 15 minutes’ time – if that works, simply re-enter your preferred central heating settings.
  • Try turning the electrical supply to the boiler off and on. The switch is usually near the boiler or in the airing cupboard. This will reset your boiler and may resolve the problem.
  • If your boiler fails and you have an electric immersion heater, you’ll always have the option for hot water by turning on the immersion isolator switch, which will be in or just outside your airing cupboard. Please note that only heating systems with a hot water storage tank located in an airing cupboard are likely to have an electric immersion heater.
  • In most cases, one of these tips will fix your heating so that you don’t have to wait for an engineer – meaning you can get toasty-warm again in no time.
