Insurers have been set new targets for updating policy and vehicle details on the Motor Insurance Database (MID).
It comes as the Motor Insurers' Bureau (MIB) launches its 'fit for purpose' programme, which aims to help the industry meet the government set goals.
From 1 January 2008, all MID1 cars, which account for 95% of vehicles on the road, will be required to be uploaded on the MID within seven days of the policy inception.
MID2 policy records which contain generic policy information such as policyholder name, address and policy number must be loaded from inception date of the policy, or within 14 days of any relevant amendment being made to the policy that affects that data.
MID2 vehicle records which contain information relating to the specific vehicles covered by that policy, such as vehicle registration mark and make and model, must be loaded onto the MID within 21 days of the relevant effective date.
Ashton West, MIB chief executive, said: "For successes to continue and to meet the requirements of the new legislation there is a need to improve the efficiency of the database.
"Compliance with the targets will guarantee the role of the efficiency of the database in enforcement laws on uninsured driving, and will make a massive contribution to bringing the number of offenders down."
