I didn't get a chance to request the cctv footage yet, thanks for the link with my right to view it. Also I was able to take a look at the damage. It's not too bad, there had been a mark there previously from the previous owners but it is worse now. I'll be able to polish it to an acceptable standard as the rest of the bumper is peppered with road rash and could do with a repaint anyway.
The paint work on the car is not in great condition as I've sort of been putting the cosmetics to one side whilst I got the mechanicals up to scratch. I didn't even a have a coat of wax on it. Talk about swirl heaven! The car is now in great condition mechanically so today I've started polishing it or 'mopping' to improve the paint. So far today I got the roof side pillars and boot lid fully polished and protected with two coats of wax.
