About us

We’re Network Certification Body (NCB) – the UK’s certification partner of choice for the rail industry.

It’s our job to assess, assure and certify infrastructure and vehicles on Britain’s railways.

We were established in 2012 as an independent subsidiary of Network Rail – with offices in London, Derby, Birmingham, York, Manchester, Glasgow and Milton Keynes. We’re proud to provide helpful experience and advice, gained from delivering certification services to over 80% of the UK’s rail infrastructure projects.

We provide conformance assessment and advisory services across:

Rail Infrastructure

Rail Vehicle

Rail Freight

Rail Systems

Rail Plant

Load units

How we’ll help you

At the NCB we provide insight into the future of rail infrastructure standards, providing solutions that work for you, as well as helping to write the standards for the industry.

We’ll work closely with you from the start of your project to minimise the risk in acheiving compliance, saving you both time and money. Any NCB certification is more than just a piece of paper – its a mark of quality.

We don’t just tick boxes,
we protect your reputation.
