Tube Flooring issues

Request ID: FOI-2918-2324
Date published: 13 December 2023

You asked

There was a news report from 2018 that reported issues with the flooring in 96TS floors lifting possibly caused by the failure of the adhesive used. Are the LU investigation reports publicly available for this issue?. Is there any information at all available about this issue or any other LU stock flooring issues that have been encountered?

We answered

Our ref: FOI-2918-2324

Thank you for your request received by Transport for London (TfL) on 17 November 2023 asking for information on Tube flooring issues.

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’.

There is no summary report of LU stock flooring issues as we have a long, rich history of dealing with a large range of flooring issues. For a comprehensive answer to such an open question, multiple data sources would need to be interrogated, spanning a long historical timespan, which we have calculated would considerably exceed the cost limit to provide a response to your current request.

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.

Although your request can take the form of a question, rather than a request for specific documents, TfL does 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. If you have specific questions relating to these topics we may be more easily able to respond to these than to a request for any information held.

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

Yours sincerely,

Tahsin Prima
FOI Case Officer
General Counsel
Transport for London
