As stated in Mayor's Question 2019/0496, TfL does not use agencies for PR or public affairs work.
The only exception is the Art on the Underground programme, which contracts a specialist Arts PR support agency to communicate the programme as TfL do not have this expertise in-house. Art on the Underground’s work is part-funded by external sources, including commercial sponsorship, grants and sales income from selling limited editions prints and books online, as well as other products like artist designed tiles through specialist retailers. This income covers the cost of the PR support. This income can be seen in the ‘income received’ column of the below table.
In addition, over the period TfL’s Property Development programme contracted an agency to conduct specialist local community engagement to support the delivery of much needed new, affordable homes on TfL land. Crossrail 2 and TfL also contracted agencies to support in local community event planning and logistics work. These companies were not contracted to perform PR or public affairs work.
TfL is currently unable to share information on its spend with marketing and digital agencies as it is in the process of retendering its main media and creative agency contracts. Disclosing its current and previous spend would prejudice TfL’s ability to achieve best value in this tender. However, once this process is complete, TfL will be happy to follow up and share this information with you.
For completeness, as provided in Mayor's Question 2019/0496, please see attached a table detailing the spend for agencies fitting your description from 2014-15 to present. This table has been updated to show spend from January 2019 – 31 May 2019.
