TfL Ref: FOI-0507-2324

Thank you for your request which we received on 12 May 2024, asking about ULEZ charges.

Your request has been considered in accordance with the requirements of the Environmental Information Regulations (EIR) and our information access policy.  

Unfortunately we do not hold the information you have requested. 

The ULEZ operates using Automatic Number Plate Recognition technology. Each entry point to, and exit from, the zone is clearly signed and as a vehicle enters, leaves, or drives within the zone its registration is recorded along with an image of the vehicle.

When the three day payment period has expired, the list of vehicles observed in the zone is compared against the vehicles for which a charge has been paid and those which are 100% discounted, exempt from the charges. Where a match is found the image and record of the vehicle is deleted. If no match is found the details are retained for enforcement and Auto Pay purposes.

As the records of vehicles for which a charge has been paid are deleted, we are unable to retrospectively verify whether a vehicle, for which a charge has been paid, has been in the zone.

The regulations governing the ULEZ do not facilitate the refunding of unused daily charge payments. If we do refund a charge as a gesture of goodwill the reason for the refund is not recorded.  

Please see the attached information sheet for details of your right to appeal.

Yours sincerely
