Our Ref:         FOI-2239-2425

Thank you for your request received on 16 October 2024 asking for information about advertising that has appeared on our network for the firm Wahed.

Your request has been considered under the requirements of the Freedom of Information Act 2000 and our information access policy. 

I can confirm that we do hold the information you require. However, to provide the information you have requested would exceed the ‘appropriate limit’ of £450 set by the Freedom of Information (Appropriate Limit and Fees) Regulations 2004. 

Under section 12 of the FOI Act, we are not obliged to comply with requests if we estimate that the cost of determining whether we hold the information, locating and retrieving it and extracting it from other information would exceed the appropriate limit. In this instance, we estimate that the time required to answer your request would exceed 18 hours which, at £25 per hour (the rate stipulated by the Regulations), exceeds the ‘appropriate limit’.

You may be aware that TfL recently experienced a cyber security incident ( https://tfl.gov.uk/campaign/cyber-security-incident ). Following this we have limited access to some of our systems, and we are currently unable to run email searches remotely Therefore, at this time, to answer your request, staff who may have been involved with this advertising would each have to manually search for any emails. These would then need to be manually checked to confirm they were relevant to your request, extract from their individual mailboxes and then collated. We have identified 17 key members of staff who may have received or sent emails on this subject, it may be the case that additional employees hold information relevant to your request. A preliminary search carried out by one of these identified over 100 email files. Whilst these may not all be relevant, and would likely include duplicates, each email would need to be manually checked and collated. With all staff identified carrying out this task across their own mailbox, we consider that answering your request would take an excessive amount of time, exceeding the cost limit described above. 

To help bring the cost of responding to your requests within the £450 limit, you may wish to consider refining your requests to concentrate on matters which are important to you. 

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

Yours sincerely
