TfL Ref: FOI-3956-1920

Thank you for your request received by Transport for London (TfL) on 28^th March 2020 asking for information about the Highgate Service Control Centre.

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

Specifically you asked:

“Please provide copies of any maintenance and cleaning reports relating to the air conditioning system at Highgate Service Control Centre.

I would also like a copy of any applicable TfL cleaning and maintenance standards.

Please provide a copy (for as many years as possible) of faults raised on the air conditioning and associated control systems at Highgate SCC since the site became operational.”

I can confirm that we hold the information you require.

Please find attached the Planned Preventative Maintenance (PPM) schedules for the air conditioning system at Highgate Service Control centre (the pdf documents). Also attached are the most recent attendance and fault records (the spreadsheets - note that you may need to expand the width of some columns to read the data in full).

If this is not the information you are looking for, or if you are unable to access it for any reason, please do not hesitate to contact me.

On a more general point, please note that the Government has announced a series of measures to tackle the Coronavirus. It is essential for London, and in particular for all critical workers, that we continue to provide a safe transport network that enables them to make the journeys they need to. In current circumstances, we are not able to answer FOI requests readily and we ask that you please do not make a request to us at present. Answering FOI requests will require the use of limited resources and the attention of staff who could be supporting other essential activity. In any event, please note that our response time will be affected by the current situation.

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,

David Wells
