This is interesting research from QuestGates and highlights the importance of accurate record keeping by the DVLA; stolen vehicles are being `wiped’ from the system, which creates obvious problems for insurers and future owners alike.
New research by QuestGates, the UK’s largest owner-managed loss adjusting and claims solutions group, has led the National Audit Office and Home Office to recognise that the police administrative process known as ‘weeding’ is driving a worrying stolen vehicle data gap.
The issue is simple but serious, with wide ranging and overwhelmingly negative implications for motor insurers and used car buyers.
When a vehicle theft is reported, a Lost or Stolen (LoS) marker is placed on the Police National Computer (PNC). If that marker is not ‘confirmed’ within six weeks, the record is automatically removed, ‘weeded’, and the LoS status will not be conveyed to the Driver and Vehicle Licensing Agency (DVLA).
Affected vehicle registrations will therefore show as ‘clear’ on PNC and DVLA checks, massively decreasing the chances of successful recovery, among other unfortunate impacts.
In the most comprehensive study of its kind, Freedom of Information Act requests were sent to 44 individual constabularies in England and Wales. The responses indicate that in 2025 alone, at least 20,000 stolen vehicle records never reached the DVLA.
If, as is believed to be the case, the weeding activity has been consistent over many years, the sums involved will be eye-watering.

Using the most conservative methodology, the discrepancy between the police and DVLA stolen vehicle datasets in 2025 was 20,282, representing an 18.83% data gap. Alternative methodologies increase this to almost one in four (24.42%).
Philip Swift, Technical Director – Motor at QuestGates, said: “We thank the National Audit Office (NAO) for engaging with this important matter and for raising it with the Home Office. As far as we are aware, this is the first time the government has recognised that weeding is a problem.
“There are, of course, legitimate reasons why the datasets may differ. Prompt recovery or subsequent cancellation of a reported theft, for instance. However, you would expect such trends to be roughly even across constabularies. Our research shows wild differences. In Merseyside and Gwent, for example, the DVLA are alerted to less than half of all reported vehicle thefts. We have an overflowing file of cases where we can clearly demonstrate that weeding has occurred.
“Now we have rock-solid evidence of the shocking scale of the problem, we urge all interested parties to work together to find a solution. Left as is, the chances of successful recovery reduce dramatically, fraud opportunities increase, vehicle provenance check providers may inadvertently report incorrectly, and innocent purchasers are exposed to a greater risk of buying a stolen vehicle. There’s also the time-consuming cost to the police of reinstating weeded records.
“Our insurance partners rely on DVLA data being accurate, so we’re calling for urgent action. First, for tackling this to be prioritised as part of the new National Law Enforcement Data Service. Second, to consider an interim solution of immediately ceasing the need to ‘double confirm’ reported thefts. Third, to launch an official audit of how many records have historically been weeded, with a view to undertaking the necessary reinstatements.”
What is weeding?
One factor influencing vehicle theft statistics is a process known as “weeding” – the automated removal of a “Lost or Stolen” (LoS) marker from the Police National Computer (PNC) if the theft report is not confirmed by the constabulary within six weeks. If weeded, the record never passes to the DVLA, creating a data discrepancy.
