Become a TfL supplier

Pre-qualification (rail, underground and major projects)

Railway Industry Supplier Qualification Scheme (RISQS)

The selection of suppliers to London Underground, Major Projects, Elizabeth line, London Overground, Trams and Docklands Light Railway makes use of a qualification scheme called RISQS.

We use RISQS to select suppliers who meet the criteria for our competitive tendering processes. RISQS is an independent industry-wide selection scheme and is also used by Network Rail. Find out more about RISQS.

Suppliers need to register in RISQS should they wish to supply to any of the TfL business areas stated above. Additionally, suppliers may need to undergo a health and safety audit to obtain the Industry Minimum Requirements (IMR) assurance rating. This audit is undertaken through RISQS.

If suppliers have any questions regarding our use of RISQS, please email us at

Electronic tendering

Our eTendering system, Ariba Network, is a web-based tendering tool that supports procurement activities and collaboration between the buyer and supplier.

If you are a supplier you should register on Ariba Network before tendering for opportunities with TfL.

Supplier registration

You can find full instructions and further information on how to register as a supplier.


We recommend that potential suppliers register on CompeteFor in order to benefit from:

  • E-alerts about 'matched' opportunities
  • Seeing who has been awarded and shortlisted for contracts
