Essential Tips for Preparing Your Radiators for Efficient Autumn Heating

As the leaves start to fall and the evenings get cooler, it’s the perfect time to prepare your home for the colder months ahead. One of the most overlooked yet essential tasks is making sure your radiators are clean, efficient, and ready to keep you warm. A little bit of maintenance now can make a big difference in comfort—and in your heating bills—once autumn and winter set in.

1. Give Your Radiators a Thorough Clean

Dust and dirt naturally build up on radiators over the warmer months, especially if they haven’t been used for a while. This dust doesn’t just look unsightly—it can also stop heat from circulating properly.

• Vacuum between the fins: Use the narrow attachment on your vacuum to remove hidden dust.

• Wipe down the surface: A damp cloth with your favourite diluted disclin disinfectant. Make sure radiators are switched off and cool before cleaning.

• Don’t forget behind and underneath: Heat rises, so keeping these areas clean helps heat circulate more effectively around your room.

• For an extra deep clean and fragrance boost. Place a towel and bowl underneath your radiator a pour your disinfectant down pipes of your radiator this will help remove any last bits of dust and when you turn on your heating it will fill your room with fragrance.

2. Bleed Your Radiators

If your radiators have cold patches—especially at the top—it’s a sign that trapped air is stopping hot water from filling the system properly. Bleeding them is quick and simple with a radiator key.

• Turn off your heating.

• Place a cloth or small container under the bleed valve.

• Slowly turn the valve until you hear a hiss of air escaping.

• Once water starts to drip out, tighten it back up.

This simple step ensures your radiators heat evenly, keeping your rooms warmer and reducing wasted energy.

3. Check Your Boiler Pressure

After bleeding, it’s a good idea to glance at your boiler pressure gauge. If it’s too low, your system may need topping up with water. Follow your boiler’s manual for instructions, or call a heating engineer if you’re unsure.

4. Move Furniture Away from Radiators

It’s tempting to keep a sofa snug against the wall, but if it’s blocking a radiator, it’s also blocking heat. Rearranging furniture so radiators are unobstructed will help warm air circulate freely throughout your home.

5. Consider a Radiator Reflector

If your radiators are mounted on external walls, fitting reflective panels behind them can prevent heat loss and bounce warmth back into the room. It’s a small investment that can make a noticeable difference.

6. Schedule a Boiler Service

Autumn is the ideal time for a professional boiler service. Not only will this keep your system running safely, but it will also ensure it’s working as efficiently as possible before winter demand kicks in.
