After a bit of brainstorming, I rememberd a place my dad used to go to for panels in Nuneaton, Warks. So I gave them a ring and have been quoted £36+vat for a pre-facelift wing, and £56+vat for facelift.
From what I can remember the quality was good from them but that was going back a few years so things may have changed, but the reason they're cheap is because they are trade prices but the company is happy to sell over the counter.
The company is called Nuneaton Replacement Panels and for those interested the number is 024 7638 7326. Hope this will help someone
