It's like a metalic tapping, there's no specific frequency to it, sometimes it's louder than others. I think it only occurs when the system's running though.
It's not air in the system, I've bled all the radiators and that isn't the problem.
Any thoughts?

You sure it's not just thermal expansion? Has it only just started making this noise? One of our rads makes a similar noise when it's heating up but it stops when it's hot.
