As the UK winter approaches, your home’s warmth becomes more than just a comfort—it’s a necessity. Unfortunately, it’s around this time of year that many households discover their heating systems aren’t ready to handle the cold.
Whether it’s radiators that won’t heat up, boilers that break down, or pipes that freeze, problems in the colder months are inconvenient and costly.
In this guide, we’ll show you how to winter-proof your home heating system, prevent common cold-weather issues, and what to do if things go wrong. We’ll also include some expert tips that could save you money and stress all winter long.
Why Winter-Proofing Your Home Heating System Is Essential
Your home heating system works hardest during the winter months, so preparing it before temperatures drop is key to avoiding breakdowns, inefficiency, and sky-high energy bills.
A little preparation now can prevent emergency repairs later—and ensure your family stays warm.
Step-by-Step Guide to Winter-Proofing Your Heating System
1. Get Your Boiler Serviced
An annual boiler service is the most effective way to keep your home heating system running efficiently and safely. A Gas Safe registered engineer will check for wear and tear, test safety controls, and ensure it’s running at maximum efficiency.
A boiler service can also catch minor issues before they become expensive problems. If you haven’t had one this year, now’s the time.

2. Bleed Your Radiators
If your radiators feel cold at the top and hot at the bottom, trapped air is likely the cause. Bleeding your radiators helps your home heating system heat up more effectively, which can save energy and improve overall comfort.
To bleed them, simply turn off the heating, use a radiator key to release the air, and tighten the valve once water starts to escape. Have an old towel ready!
3. Check the Boiler Pressure
Low pressure can cause your home heating system to run poorly or not at all. Most combi boilers work best between 1 and 1.5 bar. You can top it up yourself using the filling loop, but if you’re unsure, it’s always safer to call a professional.
4. Insulate Pipes and Hot Water Tanks
Frozen pipes are a nightmare—and one of the most common causes of heating system failure in winter. Use pipe lagging (available at most DIY stores) to insulate external and loft-based pipes, especially the condensate pipe from your boiler.
Insulating your hot water tank can also reduce heat loss and lower your energy bills.
5. Set Your Thermostat Wisely
Smart thermostats are a great way to control your home heating system more efficiently. If you don’t have one, consider setting your thermostat to a consistent temperature (typically 18–21°C). This reduces strain on your system and can prevent pipes from freezing when temperatures plummet overnight.
6. Test Everything Before It Gets Too Cold
Don’t wait until the first frost to turn on your heating. Run your boiler and radiators in early autumn to test them out. Look for cold spots, strange noises, or error codes—these early warning signs give you time to fix issues before winter arrives.
What If You’ve Left It Too Late?
If you’ve skipped regular maintenance and your home heating system fails during winter, don’t panic—but act quickly.
– Call a Gas Safe Engineer
Only use a qualified, Gas Safe registered engineer to repair or replace faulty systems. Avoid cowboy installers, especially in an emergency. Remember, cheap fixes often lead to expensive problems.
– Use Portable Heaters Safely
If you’re without heating temporarily, use electric space heaters—but never use open-flame devices like gas stoves indoors. Ensure good ventilation and follow manufacturer instructions closely.
– Apply for Emergency Help If Needed
If you’re vulnerable, elderly, or have children and no heating, you may qualify for emergency help from your local authority or energy supplier. Charities like National Energy Action also offer winter support to those in need.
Bonus Tips to Save on Heating Bills
- Install radiator reflectors to bounce heat back into rooms
- Use draft excluders on doors and windows
- Keep internal doors closed to trap heat
- Schedule heating for peak times (e.g., mornings and evenings)
- Don’t block radiators with furniture or heavy curtains
