similar thing happened to me a few years ago.
I was hit by another driver in Dec, then another clown crashed into the back of my car the following Jan.
Although your NCD is protected, if you have 2 claims in 3 years, it affects your premium.
I had to wait 9 months to get both of these claims settled, as the other insurers haggled, before finally paying out. In the meantime, I had to pay 2 lots of �100 excess,a nd my premium went up by �150.......leaving me �350 out of pocket.
The good news was, as soon as the claim was settled they refunded me, and finaly, also claimed back some costs.
You'll have to let any new insurers know about your claim - they share a database anyway - and pay the extra. But someday you'll get the money back.
