TfL Ref: FOI-2542-2122
Thank you for your request received by Transport for London (TfL) on 3rd February 2022 asking for information about ULEZ charges.
Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.

I am afraid that TfL does not hold the requested information.
ULEZ operates using Automatic Number Plate Recognition (ANPR) technology. Each entry point to, and exit from, the zone are 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 or listed on an Auto Pay account. 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 purposes. In light of this we do not retain details of the time at which a vehicle was used in the zone when a charge has been purchased. We therefore do not hold the information you require.
Please see the attached information sheet for details of your right to appeal.
Yours sincerely,
David Wells FOI Case Officer FOI Case Management Team General Counsel Transport for London
