Thousands of rogue commercial policyholders are facing fines of up to £5,000 after failing to supply their vehicle details to the Motor Insurance Database.

The Motor Insurers' Bureau (MIB) has written to 3,000 fleet and motor policyholders giving them a two-week deadline to provide the required information to their brokers or insurers.

After the deadline expires the MIB will forward details of those that have not responded to the police for prosecution.

“We have given rogue policyholders their final warning,” said Neil Drane, head of the Motor Insurers' Information Centre at the MIB.

Earlier this year, the MIB revealed that 14,000 open cover policies, which collectively account for around 200,000 vehicles, were not included on the Motor Insurance Database.
