Our ref: FOI-3715-2425/GH

Thank you for your requests received by Transport for London (TfL) on 14 & 20 February 2025 asking for information about ULEZ.

Your request has been considered under the requirements of the Environmental Information Regulations and our information access policy. I can confirm that we do hold some of the information you require.

However, in accordance with the EIR, we are not obliged to supply the information on the number of PCNs issued at specific locations, as this information is subject to a statutory exception to the right of access to information under regulation 12(5)(a) – international relations, defence, national security & public safety (in this instance specifically public safety), regulation 12(5)(b) – the course of justice, the ability of a person to receive a fair trial or the ability of the public authority to conduct and inquiry of a criminal or disciplinary nature – (in this instance specifically the course of justice), and regulation 12(5)(e) – confidentially of commercial or industrial information where such confidentiality is provide by law to protect a legitimate economic interest.

The rationale for this is explained in more detail in a published response to a previous information request which is available on our website here:

https://tfl.gov.uk/corporate/transparency/freedom-of-information/foi-request-detail?referenceId=FOI-0970-2324

TfL has no control of parking at Heathrow, and therefore we do not hold any information regarding online bookings.

If you are not satisfied with this response please see the attached information sheet for details of your right to appeal.

Yours sincerely
