Sounds like this is your first 'brush' with the world of motor insurer's, Kev.
Keep in mind 2 things:
1 You can do the repairs for £200, but that will not include labour. I don't know what body shops charge these days, but I'd be surprised if it's less than £50 per hour
2 The insurance company will try and settle at the least possible cost to themselves, so if you make them an offer that you will accept £x and keep the car, they will got for it, provided, of course, that x is substantially less than the value of the car or the cost of repairing it.
Look on the bright side, you keep the car (with little or no visible damage), have a few quid to pay off some of your cc debt, and you don't have to borrow more money for a replacement.
BTW, rather an unfortunate number plate in the light of the revelations in the NOTW last Sunday
