A description of RISQS, taken from their website reads;
"We are the single entry point for suppliers to the rail industry. Buyers of products and services throughout the GB rail industry use RISQS as its supplier qualification service.
In short we help suppliers sell in to the GB rail industry by providing an open, fair and transparent way for them to be formally recognised as capable providers of products and services.
This means we support Network Rail, Transport for London, passenger and freight operating companies, rolling stock organisations, main infrastructure contractors and many other buying organisations in the management of supply chain risk.
The scheme embraces rail's qualification arrangements previously known as Link-up. RISQS is industry-owned, sponsored by a board of representatives from across the rail industry. This reports into the RSSB Board, and RSSB provides a range of services to support operational delivery of the scheme.
This provides the industry ownership and governance of its supplier qualification arrangements."
