Pre-qualification (rail, underground and major projects)


If you supply goods, works or services under Railway Industry Commodity Classification List (RICCL) codes directly to TfL Rail Modes (comprising London Underground, Major Projects, Elizabeth line, London Overground, Trams and Docklands Light Railway) or want to do so, TfL uses the Railway safety and Standards Board (RSSB) Rail Industry Supplier Qualification Scheme (RISQS) as a 'Qualification System' under the Utilities Contract Regulations (2016).

This allows us to choose to select participants directly from the 'Qualification System' without placing a further 'Find a Tender' service call for competition.

For suppliers of safety critical goods, works or services (i.e. RICCL codes) who want to contract directly with our TfL Rail Modes, you should register on RISQS and become a supplier with audited status. RISQS is both a Qualification System under the Utilities Contract Regulations and an assurance system run by the Railway Safety and Standards Board.

We have chosen to use RISQS as our assurance system for suppliers with whom we contract directly. We do not mandate RISQS on our Tier 1 suppliers and it is up to them how they assure their own sub-contractors and sub-suppliers.

If you supply goods, works and services under RICCL categories to buyers other than us, you should check with the relevant buying organisations to find out which supplier assurance system(s) they use, if at all.
