The PCL was developed in conjunction with Network Rail. It involves the RISQS team taking on the responsibility for conducting audits on suppliers’ management systems required for holding a PCL. 

This involves a series of questions to confirm the required systems are in place before Network Rail check delivery by conducting the onsite visits. 

Initially we will be running this audit as a pilot to test the audit flow and the quality of assurance before this audit is made available to other RISQS buyers. This extension will help the railway industry achieve efficiencies wherever possible. 

We have already had a steady stream of enquiries from Tier 1 contractors to book the audit. If you are yet to do so, please contact to arrange your audit. 

Commenting on the announcement, Phil Smith, RISQS Scheme Manager said: 

‘The work we’ve done with Network Rail regarding the Principal Contractor Licence is just one part of our 2023 vision to introduce new channels that lower entry barriers and improve supply chain efficiencies across the railway network. This work will continue at pace during the remainder of the year and into Control Period 7.’ 


If you are not a Principal Contractor under the Construction (Design & Management) Regulations 2015 then you are exempt from this audit. 

Any Buyers wishing to discuss using the PCL audit for their Supply Chain please contact Phil Smith via
