Why you should check your boiler now

As part of Gas Safety Week, we’re sharing why it’s so important that you check your boiler now so it’s ready and safe to use in winter.

Why should you check your boiler in summer?

Use your heating before you need it to make sure it works when the temperature starts dropping in the winter months. We recommend that you check your heating on a regular basis to ensure that everything continues to operate properly. We receive a high volume of calls in cold weather, so these preventative actions help you stay a step ahead.

The essentials to managing your gas boiler

Try to:

  • When initially testing your boiler, make sure you have set your thermostat to above room temperature and check that radiator valves are turned on.
  • Check your thermostat batteries and replace these if necessary.
  • Check your carbon monoxide alarm batteries. If your alarm is still not working after you have fitted new batteries then contact us immediately.
  • In cooler weather, heat your home to a comfortable temperature of between 18-20 degrees.
  • Dust off internal/external air vents and keep them free of debris.
  • Get to know the controls for your heating system and use your thermostat and thermostatic valves on the radiators to control the temperature of your house.
  • Turn down thermostatic valves on the radiators in rooms which are not in use.
  • Leave the settings alone once you have found a comfortable heat.
  • Keep the doors closed throughout the house to prevent heat from escaping.


  • Allowing internal temperatures in your house to fluctuate causing spikes in temperature.
  • Covering up air vents.
  • Turning thermostat temperature up by too much.
  • Putting large items of furniture in front of radiators – this will prevent heat from being distributed throughout your house.
  • Letting your hot water tank temperature get below 60 degrees c.


If you have any issues with your boiler after making these checks, contact us to report the issue. Please check the display on the boiler for any fault codes as this is useful information for the contractor.
