We answered
Our ref: FOI-2123-2223/GH
Thank you for your request received by Transport for London (TfL) on 25 November 2022 asking for information about the number of ulez trips paid for but not made.
Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy.
Unfortunately we do not hold the information you require - it may be useful if I outline how we operate the Ultra Low Emission Zone. The scheme operates using Automatic Number Plate Recognition technology. Each entry point to, and exit from, the zones 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.
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.
If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.
Yours sincerely
Graham Hurt FOI Case Officer FOI Case Management Team General Counsel Transport for London
