Accredited official statistics status
Accredited official statistics status means that our statistics meet the highest standards of trustworthiness, quality and public value, and it is our responsibility to maintain compliance with these standards.
The designation of the vehicle excise duty evasion estimates as accredited official statistics was confirmed in April 2012 following a full assessment against the Code of Practice by the Office for Statistics Regulation.
Changes to these statistics
Since the latest review by the Office for Statistics Regulation, we have continued to comply with the Code of Practice for Statistics, and have made the following improvements:
- continually reviewed the methodology with respect to the survey sites and their impact on the final estimates
- we implemented improvements to the methodology for motorcycles and other vehicles observed in small numbers
