NAS Certification for
Rail Industry Contractors
Independent, evidence-based compliance certification for UK rail contractors, infrastructure suppliers, and trackside service providers.
Prove your compliance to Network Rail, HS2, Transport for London, Docklands Light Railway, and rail procurement teams — with a live certification profile, not a static PDF.
Why It Matters
Rail Procurement Demands Verified Compliance
Rail principal contractors, Network Rail supply chain managers, and HS2 procurement teams face increasing pressure to demonstrate that their supply chains are compliant before work starts — not just when something goes wrong.
For rail subcontractors and specialist suppliers, holding NAS certification signals to buyers that your compliance has been independently reviewed and documented — not self-declared on a form.
With a live NAS profile, you share a single, current compliance view with every buyer — reducing repeated document requests and strengthening your standing on pre-qualification questionnaires.
- Independent, evidence-based NAS certification
- Demonstrates compliance to Network Rail, HS2, and principal contractors
- Supports PQQ and pre-qualification submissions for rail frameworks
- Health & safety policy and RAMS assessed by independent assessors
- Workforce competence evidence (PTS, COSS, plant cards) reviewed by an assessor
- Public register listing — verifiable by any buyer instantly
Certification recognised across the UK rail network — mainline, underground, light rail and metro.
What Gets Assessed
NAS assessment reviews real evidence across six core areas. Here's what rail contractors typically need to demonstrate.
Health & Safety Policy
A current, signed H&S policy covering rail-specific site risks and workforce responsibilities.
RAMS Documentation
Risk Assessments and Method Statements relevant to trackside and infrastructure work.
Insurance Evidence
Valid Employer's Liability and Public Liability insurance certificates with appropriate cover levels.
Workforce Competency
Evidence of workforce training — PTS cards, COSS, ICI, and other rail-specific certifications.
Compliance Policies
Environmental, Equality & Diversity, and GDPR policies reviewed and independently assessed.
Business Registration
Verified UK company registration and operational structure evidence.
PTS Cards, COSS Authorisations and Rail Competence Evidence
Rail buyers want to know your people are competent and in date. At assessment, NAS reviews the training and competence records you hold for your workforce, including rail-specific cards and authorisations.
Keep these records current between assessments: your renewal includes a fresh review of them.
- PTS (Personal Track Safety) cards
- COSS & ICI authorisation records
- CPCS, NPORS, and plant operator cards
- First Aid and safety training certificates
