I'm no bodyshop expert, but that looks like it could be pulled, and a bit of filler to make it right again. New panel would be expensive new. If you did go down that route then you need to find someone who is breaking a wrecked dc2, and would cut the panel off.
I think it could be repaired though. I don't know where abouts in Hertfordshire you are, but there is a bodyshop called car magic in Chesham. They do repair work to a really high standard.
