Pre-qualification (rail)

Railway Industry Supplier Qualification Scheme (RISQS)

RISQS (formerly Achilles Link-up) is the UK rail industry supplier qualification scheme providing a single common qualification process for suppliers. It is shared by the UK rail industry (including London Underground) and is operated by Achilles Information Limited.

We use RISQS to obtain suitable suppliers (by applying selection criteria) for use in competitive tendering processes mainly for rail and Underground projects. Find out more about RISQS.

Electronic tendering

Our eTendering system, ProContract, 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 ProContract 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:

  • Equal access to a range of opportunities from major buyers and their supply chains, offering achievable packages of work, particularly for small and medium-sized suppliers
  • E-alerts about 'matched' opportunities
  • Seeing who has been awarded and shortlisted for contracts
