Replaced rear discs and pads, checked the wheels for play and there all good. Still don't know what it could be, driving me an the misses crazy!

Had this too mate, replaced exhaust and rear tyres, still the noise was there. Bloody awful noise!

The wheels didn't show any signs of play or wear, and even a skoda technician couldn't find the problem!

Turned out to be a nearside rear wheel bearing. £80 repair. Sorted

Good luck
