NCB Rail Assurance

What NCB Rail Assurance does

NCB Rail Assurance (legal name: Network Rail Certification Body Limited) is a UK-based independent railway assessment and certification body, established in 2012 as a wholly-owned subsidiary of Network Rail. The company provides UKAS-accredited Assessment Body (AsBo), Approved Body (ApBo), and Designated Body (DeBo) services that enable rail projects to obtain Office of Rail and Road (ORR) authorisation. Its work covers independent safety and interoperability assessment against the Common Safety Method for Risk Evaluation and Assessment (CSM-RA), Railway Interoperability Regulations (RIR), Technical Specifications for Interoperability (TSI), and UK National Technical Specification Notices (NTSNs) for rail infrastructure, rolling stock, signalling, energy, and operational changes.

The company operates a professional services model centred on its proprietary Progressive Assurance Methodology (PAM), a five-step approach combining early engagement, shared goals, progressive assurance, risk-based assessment, and corrective actions. Engineering teams are employed directly (not contracted) and co-located on client projects across seven UK offices (Milton Keynes HQ, London, Derby, Birmingham, York, Manchester, Glasgow). Supporting the core services are specialist offerings including Cybersecurity Assurance against TS50701, Intermodal Load Unit codification under UIC IRS 50592 (serving clients in Europe, Asia, America and Africa), Design for Reliability auditing for Network Rail product acceptance, Route Compatibility Studies, and training courses in CSM-RA and PAM. Notable project achievements include the UK's first Energy TSI authorisation on the North West Electrification Programme and an industry-first 'clean' authorisation on the Midland Main Line London to Corby section.

Revenue is generated through bespoke professional service engagements billed to clients for assessment reports, technical files, and certificates of verification, with pricing not publicly disclosed. NCB claims to certify over 80–90% of UK rail infrastructure projects and serves major clients including Network Rail, Transport for Wales, Welsh Government, Serco, CAF, Loram, and various UK government departments. The company holds BSI certifications to ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018, and has 32 employees as of the latest disclosure.
