JVR Consultancy is calling on organisations within the UK rail industry to place greater focus on supplier assurance and contractor compliance, warning that rail accreditation schemes often involve far more operational detail than businesses initially expect.
The consultancy says many companies entering the rail market wrongly assume that existing ISO certifications or generic health and safety frameworks will be enough to satisfy rail industry requirements. However, sector-specific standards typically require more robust operational controls and tailored compliance procedures.
JVR Consultancy works with organisations seeking support for RISQS, Achilles Link-Up and Principal Contractor Licence (PCL) preparation, helping businesses ensure their systems and operational processes meet the standards required by Network Rail and the wider rail supply chain.
RISQS remains one of the rail sector’s most established supplier assurance schemes. Businesses applying for accreditation are required to demonstrate that their management systems, operational procedures and safety controls comply with industry expectations relevant to the work they undertake.
For organisations involved in higher-risk activities, formal audits may also be necessary in addition to evidence reviews and supplier assessment questionnaires.
“Some organisations believe rail accreditation is largely an administrative exercise,” said a rail compliance specialist at JVR Consultancy. “In practice, assessors are looking closely at how businesses manage operational safety and compliance on a day-to-day basis, particularly within live rail environments.”
According to JVR Consultancy, businesses often encounter delays or difficulties because existing systems have not been adapted to rail-specific standards. Policies linked to workforce competence, subcontractor management, operational safety and drug and alcohol testing commonly need significant revisions before approval can be achieved.
The consultancy also highlights widespread misunderstanding surrounding the relationship between RISQS, Achilles Link-Up and Principal Contractor Licence requirements.
While RISQS is commonly used to assess suppliers entering the rail supply chain, Principal Contractor Licences apply to businesses directly responsible for delivering projects on behalf of Network Rail, including overall site coordination and safety management.
“PCL responsibilities extend well beyond standard supplier assurance,” the specialist explained. “Organisations holding these licences are responsible for managing operational rail projects safely, including subcontractors, welfare provision, safe systems of work and protection arrangements within active rail environments.”
JVR Consultancy also notes that maintaining rail compliance requires ongoing monitoring and system updates. As Network Rail standards evolve, businesses must ensure their procedures continue to reflect current operational expectations.
The consultancy recommends that organisations approach rail assurance as a practical operational requirement rather than simply a compliance formality, ensuring documented systems accurately mirror real-world working practices.
JVR Consultancy continues to support organisations across the rail, infrastructure, utilities and construction sectors, helping businesses strengthen management systems, prepare for accreditation and maintain compliance in highly regulated operational environments.
