Creaking rear

[CJPop]

Hi there, I've started to notice a creaking sound from nearside rear (I think). No noise driving for the first 10-15 mins, then it appears. 

At first I thought it was a suspension issue, but nothing really on bumps. Only when moving from stationary/pulling away, especially worse uphill.

If I pull away from lights very slowly, I can mostly avoid it, but I do make the drivers behind me very upset! 

Disappears above 15mph or so. Brake discs and pads seem all good. Any thoughts?
