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

* There will be further consultations on the specific design of Schedule 8, access charges and Schedule 4 in the first half of 2022 –the consultations on these topics will provide more information on next steps.

** The outcome of the comprehensive spending review in autumn 2021 may go some way to setting the funding envelope for the first two years of PR23 and is likely to be an important factor in determining the content of the HLOSs and SoFAs.

*** This timeline may change to enable us to adapt as the implementation plan for the Williams-Shapps Plan becomes clearer.
