Tapping radiator/pipe? in kitchen

Hi, when I put the central heating on, I can hear a tapping sound in the living room. On the other side of the wall is the kitchen radiator. I can't see any wet or moisture either living room side or kitchen side. It appears to be the only radiator to make a noise when central heating is on. Any ideas what it could be? Someone has already suggested that the valves may be incorrectly fitted? I haven't a clue, so any suggestions would be really appreciated. This is a new central heating system throughout house, following a house fire.
Thank you

if the copper pipe is touching a tight wooden hole this could be your problem when the copper expands

You may find it is pipework within ceiling void touching wooden joists wrapping some hairfelt lagging around pipes where they touch should eliminate this.
