Periodic review 2023 (PR23)


This section includes information about the current 2023 periodic review (PR23) of Network Rail's outputs and funding for
control period 7 (2024 – 2029).

Periodic reviews are one of the principal mechanisms by which ORR holds Network Rail to account, and secures value for money for users and funders of the railway.

PR23 will determine what Network Rail must deliver in control period 7 (CP7) and the funding it requires to do this.

On 17 June 2021 we published an open letter to launch PR23 and set out the focus of PR23 – namely safety, performance, asset sustainability, and efficiency.

We published our periodic review 2023: draft determination on 15 June 2023 and the deadline for consultation responses was 31 August 2023.
