About the buyer

Network Rail runs a safe, efficient railway, and buys as a central public body split between a national Route Services team and its regional routes. Network Rail's latest spend reporting covers Control Period 7, the 2024-25 financial year.

Safety-critical work needs audited status on RISQS, the rail industry's supplier qualification scheme, before Network Rail contracts directly.

Over the past 5 years, most of Network Rail's contract awards have been in IT services, architectural and engineering services and construction work.
