Why is my radiator making noise when off?

If it’s just creaking or clicking when your heating goes on or off, it’s just the metal of the radiator expanding and contracting. If it’s gurgling, banging or sounding like a kettle, there are a couple of home fixes you can do yourself.

Why is my radiator clicking?

Clicking and creaking noises are the most common noise a radiator will make and this is actually pretty normal. It’s most likely that this is caused by expansion of the metal after a rush of hot water flows into it. Similarly, when the radiator cools down, the metal contracts as the hot water gets cooler.

How do I stop my radiator pipes from clicking?

If you have a little bit of DIY knowledge, them bleeding air out of your radiators is a very easy plumbing task to carry out. Letting out the trapped air should stop the clicking and ticking noises and should enable you radiators to heat up evenly.

If you have steam radiators and you think that the banging could be caused by trapped water, you should drain the radiator. You can do this by turning off the boiler and gas supply. Turn off the water intake valve and wait for the system to cool down fully. Once cool, open the drain valve by turning it anticlockwise.
