You asked

To whom it may concern Please provide the following under the Freedom of Information Act: Any and all correspondence between TfL and the Mayor's Office or any London City Hall official that includes the word "Uber" since 1 January 2017. Please acknowledge receipt of this request. I also kindly request that you do not post the response to this request on your website.

We answered

TfL Ref: FOI-1582-1718

Thank you for your request received by Transport for London (TfL) on 24 September 2017 asking for information about correspondence.

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy. I can confirm 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 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 conducted a remote search of correspondence held within our email archive for all emails sent to an email address with the suffix “” that contained the keyword “Uber” over the requested time period. This search was stopped approximately a third of the way through, having reached in excess of 11,000 hits. A ‘hit’ refers to an email found within our IT system that potentially fits within the scope of your request.

It is not unreasonable to conclude that, had we allowed the search to continue running, the total number of hits would have been double this figure. Many of the hits are likely to be not relevant (such as external emails sent to both TfL and the GLA simultaneously), duplicates, due to emails being repeated within email chains or to multiple people, as well as emails being forwarded internally for discussion during this time period. Therefore the actual number of emails covered by your request will be a sub-set of these hits. However, locating those that are relevant would require us to manually review all of them to determine whether the email, or email chain, is relevant to your request and then we would need to extract and compile all of those that meet your request

As a result, we have therefore estimated that to manually locate, extract and collate all of the relevant emails caught by such a wide ranging search would considerably exceed the cost limit.

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. For example, by focusing on one particular aspect of the subject matter or for a narrowed period of time, between specific individuals and a more specific keyword.

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

Yours sincerely

Lee Hill
