When I turn the cold tap off it goes `clunk` one loud knocking noise, its recent as never used to do this.
Any thoughts on how to cure?

No, all the taps at once in the hope of letting the air out. That was what my plumber advised. Worth a try, I would suggest.

Okay, calm down and tell the OP how to fix it. New washer?
