As winter sets in, ensuring your home’s heating system is in top shape is essential for comfort, efficiency, and safety. A well-prepared system not only keeps you warm but also saves on energy bills and prevents costly breakdowns. Use this ultimate winter home heating checklist to prepare your heating system for the colder months ahead.
1. Schedule a Boiler Service
- Check for wear and tear.
- Clean internal components to maximise efficiency.
- Ensure safety measures, like carbon monoxide detectors, are functioning properly.
2. Test Your Thermostat
- Turning the heating on to ensure the thermostat accurately responds.
- Checking the timer and settings to align with your daily routine.
- Considering an upgrade to a smart thermostat for better control and energy savings.

3. Bleed Your Radiators
- Start with the radiator furthest from the boiler and work towards the nearest.
- Use a radiator key to release trapped air until water flows steadily.
4. Insulate Pipes and Tanks
- Wrapping exposed pipes with foam insulation.
- Using lagging to insulate your hot water tank.
- Keeping your heating on low during freezing spells, even when you’re away.

5. Clean or Replace Filters
- Dirty filters can block airflow and strain the system.
- Regular cleaning or replacement improves air quality and energy performance.
6. Inspect Vents and Ducts
- Clear obstructions like dust, debris, or furniture.
- Check for leaks in ducts that could waste heated air.

7. Check Carbon Monoxide Detectors
Winter means extended use of your heating system, increasing the risk of carbon monoxide leaks. Ensure safety by:
- Testing carbon monoxide alarms and replacing batteries if needed.
- Placing detectors near your boiler and in sleeping areas.
- Contacting a professional immediately if you suspect a leak.
8. Monitor Boiler Pressure
- Check the pressure gauge on your boiler.
- If it’s too low, top it up following the manufacturer’s instructions.
- Call an engineer if the pressure fluctuates frequently.

9. Insulate Your Home
Prevent heat loss by improving your home’s insulation:
- Seal gaps around doors and windows with weatherstripping or draught excluders.
- Use heavy curtains to retain heat.
- Ensure lofts and walls are adequately insulated.
10. Prepare for Emergencies
Even with the best preparation, unexpected issues can arise. Be ready by:
- Keeping emergency contact numbers for heating engineers handy.
- Having a backup heat source, such as a portable heater.
- Knowing where your stopcock and boiler reset controls are located.
