Clicking radiator, hit it with a big hammer?

[EastEnder]

It never used to do this, it's helpfully started doing it just as Jack Frost has moved in. Only the one radiator - in my bedroom, obviously. Starts up as the heating turns on, lasts for about 15 minutes - just long enough to ensure I'm definitely awake - then stops. I've got a combi-boiler, gas powered, closed system, etc. The radiators don't even have a little square valve thingy that I can attack with a bleeding key.

What's the problem and how do I fix it? I have a reasonably large hammer, but am prepared to invest in an even bigger one if required.

That's good if it's a closed system - my mum's is meant to be closed and when she bled a radiator the other day the pump fucked up.

It's expansion caused by the system heating up. I don't think there's a quick percussive fix, but turning down the thermostat on the boiler may help. If it's the pipe (not the rad itself) widening the hole in floorboards, better clamps and better lagging will help.

Get a sledgehammer and give the little pipes at each side of the radiator a good hard whack. That should learn it and you shouldn't have any more clicking.

Get a heating engineer and hit him with a hammer until he fixes it

Can I pay a heating engineer in mince pies & good cheer?

Set the timer so the heating comes on at your alarm time.

Nice try, but the heating engineer's missus (or mister) might not like it.

Are you sure about this? I thought the same about ours until earlier this week I took one off the wall and there it was hidden round the back of the radiator on the top left. Bleeding mine and refilling the system sorted out all our strange noises.
