My car policy is due to renew on 23rd Dec but the renewal is double what other insurers are quoting. Therefore I will not be renewing this year. However Tesco NCD is max 9yrs. I came to Tesco with 11yrs from a previous insurer therefore on leaving this year, without any claims, I would have accrued 14yrs. How do I get the correct NCD I have accrued from Tesco for my new insurer who have a higher level of NCD?
