No Claims Letter - won't accept more than one

Just wondering if anyone else has had a similar problem.

My brother was insured as a named driver on my mothers policy for 12 months.

When he got his own car & took out his own policy with Quinn Direct he was asked to send notification on that he was a named driver for a year on my mothers policy.

My mother had changed insurers during the 12 months (when her policy expired) so my bro got 2 letters from both insurers - one covering 8 months and the other for 4 months.

Now Quinn Direct are saying that they will not accept both letters and say he was only driving claim free for 8 months and are looking for another 600 euro.

Anyone know what the deal is here ?

Bum deal but thats the way it works NCB is only issued on completion of one years policy. Some insurers may apply the fair approach but most won't

One thing I thought of....if you stayed with the same broker you may get the letter from them.
