Canceling insurance policy after a claim against you?

[Niall]

No you cant. I went through something very similar this year. Someone drove into my parked car and the insurer (admiral) Messed up and came to the conclusion it was my fault. When i phoned to cancel, i would of lost that years NCB, had to pay about £150 (had 5 months of the policy left) but then they said because i was at fault, i would have to pay the cost of the claim which came in at £1200.
