Economic regulation

We regulate Network Rail, holding it to account for delivering high levels of performance and service, as well as good value for money – for passengers, the freight industry and taxpayers.

We also regulate railway networks separate to the national network operated by Network Rail, including the Channel Tunnel and High Speed 1, and we have a limited role in regulating the railway in Northern Ireland.

Periodic review 2018 (PR18)

At the heart of the review is our assessment of what Network Rail must achieve from 2019 to 2024, the funding it requires for this, and the incentives needed to encourage delivery and outperformance.

Network Rail regulation

We regulate Network Rail’s stewardship of the rail network for the long term – for investors, train companies and their passengers, freight customers and the taxpayers.

High Speed 1 (HS1) regulation

We require HS1 Ltd, the company that has a concession to operate and manage the railway between St Pancras and the Channel Tunnel, to be efficient and perform well.

Channel Tunnel

The Channel Tunnel is the fixed link between the United Kingdom and France consisting of two railway tunnels plus a service tunnel, operated by Eurotunnel.

Northern Ireland

We perform several broad roles in Northern Ireland: we act as the appeal body, control the network statement and monitor the competitive situation of rail services.
