TfL Ref: 3586-1819

Thank you for your request received by Transport for London (TfL) on 27 March 2019 asking for information about the Night Tube.

Your request has been considered in accordance with the requirements of the Freedom of Information (FOI) Act and our information access policy.  I can confirm we do hold the information you require.

Unfortunately, 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 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.

We have estimated that it would significantly exceed the cost limit provide a response to your current request.

We do not monitor the movement of staff in and out of each location or grade so to answer part c of your request we would need to run a large number of system reports and then analyse them and extract any relevant data manually which would exceed the cost limit on its own.

Additionally, Staff are not allocated to Stations, they are sent to Areas some of which are stations and some are groups of stations.  Therefore we would not be able to answer this part of your request accurately in it’s current form.

To help bring the cost of responding to your request within the £450 limit, you may wish to consider narrowing its scope so that we can more easily locate, retrieve and extract the information you are seeking. If you want to refine your request or make a Freedom of Information Act request in future, please bear in mind that the Freedom of Information Act allows you to request recorded information held by us. You should identify the information that you want as clearly and concisely as you can, specifying the types of document that you are looking for. You might also consider limiting your request to a particular period of time, geographical area or specific departments of the organisation.

Although your request can take the form of a question, rather than a request for specific documents, we do not have to answer your question if it would require the creation of new information or the provision of a judgement, explanation, advice or opinion that was not already recorded at the time of your request.

Please note that we will not be taking further action until we receive your revised request.

In the meantime, if you have any queries or would like to discuss your request, please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely

Sara Thomas
