So you don't mention it to your insurance company (which contradicts what you've said 2 posts ago about having to tell them "Because its a material fact and required under the terms and conditions of your policy.") which still leaves you with no car and still having to pay £2200 for insurance, just split over the remaining 11 months rather than in one go. Although I guess you could at this point cancel your insurance and hope the other party doesn't make a claim.
What are you talking about? Your insurer won't end your policy simply for notifying them of an accident!
We are talking about where you make a claim with your insurer which ends with a total loss.
