4 - 5 years ago I had 7 years protected NCB - then I had a car
accident, ahvenot had my own insurance since.  Now I want my car
insurance, but I don;t recall who I was last insured with, so I cannot
verify my 7 years protected NCB when asking for quotes.

The credit card company cannot help, is there another way I cna look
into this - perhaps using the vehicle's history, or some RAC car
history search or something for the vehicle I had the accident in?

I am running out of ideas - I actually keep all my credit card
statements, but thety are so ld the type is stuck to the plastic
protective folders, and now its completely illegible!

I wonder if your NCB would still be available after your not having
had any insurance for such a long time?

I don't know.

And I don't know of any way to track car insurance records for your
English car insurance either.

Sorry!

The only way to confirm your NCB status is with your last insurance
company. The history of car is not relevant. I'm afraid it is a matter
of remembering the name of the insurance company. If you do confirm
your NCB, whether the new insurance company would accept it after all
this time, is debatable.

I wonder if it's likely the insurance company would have done a credit
check on a new policy holder? If so, that might still be recorded on
the registers held by the consumer credit reference agencies, which
might enable you to identify the insurance company. Info on how to
