Might they have scope to claim I tried to mislead them and try to recover monies paid to third parties?

Thanks. They increased the premium by £55 this morning. I'm just worrying that they could void the policy over the excess mileage on the crash date.

This is my first post and frankly I'm a nervous wreck, so please excuse any mistakes. I had a crash last week, I drove into the back of another car and am accepting liability. When I checked my insurance policy I discovered the annual estimated (not limited) mileage is 5000. This was my estimate when I began driving in May 10, and I mustn't have updated it at renewal in May 11. Since May 11 I have done about 5500-6000 miles, and only realised this mistake after the crash. I'm third party fire theft, so am not claiming for my own car, but am scared about the potential liability for the other car. I rang my insurers today to update my estimated mileage to 10,000, and they charged £55 extra on an £1100 policy. What is the chance they will see that at the time of the crash I had done 6000 miles in 8 months on an estimated 5000 mile policy, void my cover, and recover the other party's claim from me? All I can think of right now is the possibility of becoming bankrupt and losing my job if the other party (family of 4) put in a series of whiplash claims.
