Winter Boiler Checks: How to Prepare Your Heating System for Cold Weather

As temperatures start to drop, the last thing anyone wants is a boiler breakdown. ❄️ Whether you’re at home or managing a commercial property, a few simple checks now can save a lot of stress (and cost) later in the season.

Here’s how to make sure your heating system is ready for winter.

1. Check Your Boiler Pressure

Low boiler pressure is one of the most common causes of heating problems. If your system isn’t heating up properly, take a look at the pressure gauge - it should usually sit around 1–2 bars. If it’s too low, your system might need repressurising.

2. Bleed Your Radiators

If you notice cold spots or uneven heating, air might be trapped inside your radiators. Bleeding them helps the hot water flow properly again and improves efficiency.

3. Test Your Heating Before It Gets Too Cold

Don’t wait for a freezing night to discover your heating isn’t working! Turn it on early and make sure all radiators and thermostats are working as they should. This gives you time to fix any issues before winter properly sets in.

4. Schedule a Professional Service

Even if your boiler seems to be running fine, booking a professional service can prevent hidden faults and improve efficiency. It’s also the best way to make sure your boiler is operating safely - especially when it’s working harder during the colder months.

5. Keep an Eye (and Ear) Out

Strange noises, leaks, or frequent resets are all signs your boiler might need attention. Catching small issues early can stop them from turning into major repairs later on.
