noise / sqeak at top of clutch?

Hi, my street Ka (13000miles 55 plate, serviced dec 07) is making a squeak or squeal right at the top of the clutch as it bites. Have had it in the garage and they ahve greased the engine mount but has not worked. does it in any gear change but not all of the time and doesnt seem to matter whether the car is cold or not, any comments helpful - thanks
