You asked
Hello, I am asking for information on the number of non ulez complaint vehicles there are in outer London which will be affected by the expansion of the ULEZ tax. Your letter states that "TFL has developed a list of vehicles that have been identified as likely to be affected by the ULEZ". How many vehicles are on that list?

Our Ref: FOI-0595-2324
Thank you for your request received on 31 May 2023 asking for information about compliance levels for the Ultra Low Emission Zone (ULEZ).
Your request has been considered in accordance with the requirements of the Environmental Information Regulations (EIR) and our information access policy. I can confirm that we do hold the information you require.
By way of background, in order to establish whether a vehicle is compliant with the ULEZ emission standards we predominantly use the vehicle data held by the DVLA. In most cases we can establish a vehicle’s compliance status by the date it was first registered as new. We know that all diesel cars first registered as new after 1 September 2015, and all petrol cars first registered as new after 1 January 2006 are automatically compliant with the ULEZ standards. This is because there was a legal requirement to manufacture vehicles to these standards as of these dates.
Using the data provided by the DVLA we have developed a compliance database which lists the compliance status of all UK registered vehicles. This is not a live link to the DVLA data; rather a static list of vehicles which is refreshed with new updated DVLA data every month. By updating the list regularly it ensures any update to vehicle information held by the DVLA is reflected on our database soon afterwards.
As at 23 May there are 66,034,083 vehicles contained on our database. We publish overall compliance rates in our quarterly ULEZ fact sheets. These can be found on our website (see the section headed ‘Finance, operations & performance’):
