One of radiators is ticking

Slinky

Whilst we were decorating our new house and had no carpets, we took up a floorboard to locate a particularly noisy pipe. Never mind ticking, this sounds like a gun going off....... every morning. No chance of sleeping through it. Turned out the pipe was being held in place across a joist with a bent nail which was rubbing badly. Nail removed, pipe lagged with some felt, board replaced........... pipe drilled through........ plumber called........ freshly painted ceiling below ruined.........

It's nearly always the pipes expanding, rather than the radiator itself.

If you want to, you can rip up all the floorboards, trace the pipes, and put something like felt in wherever a pipe might be rubbing, when it expands or contracts.

I just accept the ticking. It lets me know the central heating is working.

thank you, both your suggestions are useful to me and seem to be right. I also got a recommendation from a plumber which is inline with your recommendations, See below please.

****
expansion of either pipes feeding rad or rad itself expanding,pipes in floor going to rad may be squeezed by joists and as they heat and expand because they are tight they make the noise you describe ,or it could be the muck in your system has lodged in this rad,either way it is not dangerous .

I have a carpet installed around the pipes which goes into floorboard. I will take it out and check the pipes.
