Cap HPI has re-engineered its National Mileage Register (NMR) investigation process to offer a faster and more efficient service for dealerships to help protect car buyers from mileage tampering, or “clocking”.

Cap HPI’s enhanced service now integrates 500 million records from more than 20 industry sources including the DVLA, insurance claims, V5 documents, and leasing companies to provide a comprehensive defence against fraudulent activity

The service, part of the HPI Check, can help identify and address potential mileage tampering in vehicles, helping dealers comply with legal obligations and protect buyers.

John Dennis, UK sales director at Cap HPI, said: “The new approach is faster and more reliable than the previous process. It also gives users clearer data, helping them evaluate and manage risk. By saving dealers time and money through increased efficiency, we’ve created a service that supports both compliance and operational goals.”

The re-engineered NMR service compares a vehicle’s current mileage against the National Mileage Register database to verify accuracy. Developed in partnership with Trading Standards, the process ensures recorded mileage reflects the true distance travelled based on available data.

Trading Standards advises dealers to supplement the NMR check with additional diligence, such as obtaining a signed mileage declaration from the current owner; conducting a physical inspection of the vehicle to confirm its condition aligns with the recorded mileage and reviewing the vehicle’s MOT and service history.
