First things first, preparing your boiler for winter is the best way of ensuring that your family stays warm in the winter. We’ve all heard the horror stories of boilers kicking it during the cold winter months. It’s something we’d all like to avoid. Whilst you can never guarantee that your boiler will continue to work, there are things you can do to help prevent any issues.

In this blog post, we’ll share 4 simple tips to help you maintain your boiler in winter.

Check the pressure

Boiler pressure can be easy to overlook. It’s a simple check but we’ll often forget to do it until we have too. Whether your boiler is in an awkward spot or tucked away in a loft, the effort is worth it.

In the case of combi boilers especially, low pressure can quickly lead to failure. The pressure of your boiler can be found on either the front LCD panel or dial. Most boilers have a water pressure between 1 and 1.5 bars but checking the user manual to be sure is best. Once you have the right number adjust the boiler accordingly. It’s recommended that you check your boiler pressure 3 – 4 times a year.

Time for a service

If you’ve not had your boiler serviced this year now may be a good time to do so. A boiler that is serviced yearly is far more likely to run smoothly with fewer issues.

Remember to choose a Gas Safe certified engineer. An engineer that is certified that each and every check is completed and any issues are recorded and acted on.

Full power!

Running your boiler at high power and turning up the radiators to the maximum is a good way to test everything is working as it should. If you notice that there are any issues during this process it’s a good idea to get a service.

Issues during this test could indicate that you have a blockage or leak so action will be necessary.


A power flush is a way of purging the central heating and radiators of any sludge that may be lingering in the radiators. For this, you will need a certified plumber. They will fill your radiator with clean water and a corrosion inhibitor to flush out any built up debris. This will ensure that the boiler continues to work smoothly.

Whilst running checks on your boiler now may seem unnecessary it may save you from suffering in the months to come. Not least because as we enter winter, plumbers become very busy with other unfortunate homeowners.
