We answered

Our Ref:         FOI-1971-2021

Thank you for your request received on 4 January 2021 asking for information about the Wi-Fi available on the London Underground.

Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy.

Under section 12 of the FOI Act, we are not obliged to comply with a request 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. This is calculated at £25 per hour for every hour spent on the activities described. Section 12(4)(a) of the Act provides for the costs of complying with two or more requests made in a 60 working day period which are, to any extent, for the same or similar information to be combined. Section 12(4)(b) provides for requests made by different people acting in concert, or in pursuance of a campaign to be considered together under section 12.

We believe that you are working in concert with another requester that has submitted two requests in the last month regarding Wi-Fi on the London Underground. Their original request is identical to the request you have submitted. This original request was refused as we estimated that it would take over 36 hours to provide. This is because there would be a vast amount of data to review in order to extract the answers to the questions, and no particularly easy or efficient way of doing this.

We are therefore refusing both of these outstanding requests under section 12 of the FOI Act. Please note any further requests that we receive within a 60 working day timeframe from you or the other requester may also be subject to consideration under section 12 of FOI.

There is a small team available to respond to these requests and the burden placed on them has to be balanced with their substantive roles. To help bring the cost of responding to your request within the £450 limit, you may wish to prioritise the information you are most interested in and make a single request, rather than several requests in a short period of time in order to make the best use of the processing time available to you under the FOI Act.

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

Yours sincerely

Gemma Jacob
