Whether you are updating your existing hardware or installing brand new radiators, using the right radiator valves for the job will keep everything running smoothly. From angled or straight radiator valves to thermostatic options that allow for complete temperature control, our radiator accessories are crafted from quality materials and are available in a wide array of finishes - allowing you to find your perfect match.


Radiator valves act like taps, controlling how much heat your system gives out. In order to keep your central heating system running smoothly and efficiently, maintaining the condition of your radiator valves and ensuring they're the correct size for your fittings is super important.

If you have a faulty radiator valve, you'll need to replace it as soon as possible. Consider swapping your radiator valves for thermostatic options, as these allow you to stay in control of the temperature and your energy consumption.

How to fit radiator valves

Firstly, switch off your central heating system and water supply. Take the protective cap off the return valve and turn the valve clockwise with a spanner until it doesn't move any more. This will prevent any water from entering the unit.

Then, turn the valve on the opposite end of the radiator clockwise - you can do this by hand. On a thermostatic valve, turn until you see the number zero. Bleed your radiator with a radiator key - this will drain any water and fill your radiator with air. Make sure to protect your flooring and have a vessel to collect the water in - bleeding the radiator should take around 15 minutes. This is also a good time for a well-deserved tea break!

Next, unscrew the cap and remove the old valve with an adjustable spanner. Clean away any dirt with wire wool and a cloth. Position the new valve, aligning the valve cap-nut and sealing components over the end of the pipe. Tighten the cap nut with a spanner.

With your new valve successfully attached, turn your water supply back on and bleed the radiator again to allow your system to refill with water. Finally, re-pressurise your system while checking for any faults and you're good to go!
