We had an almost identical bump back a while, insurance company were very good. Allowed us to get the quotes and decide where we wanted it to go.
We had a couple of quotes £500-£750.
VW approved body shop around £2000, new door, seals, metallic paint etc, the works basically. We went this route for a number of reasons, some discussed above.
As a precaution the insurance company also replaced all 3 of our kiddy seats and bases (no quibbles) which was worth around £1000. We explained they really didn't need to do this given how it happened but they insisted.
I get what everyone is saying about increased premiums, but your insurance is going up next year claim or no claim (it never goes down and that's why we all have to shop around, right, to get it back down?!) and a claim that size pays back the last 4-5years of insurance when you didn't make a claim. Just my thoughts, but hope you get its sorted as painless and cost effective as possible.
