HS2 Ltd updated the register on a regular basis until Royal Assent of the High Speed Rail (London to West Midlands) Bill, when the final version of the register was published.
The purpose of the register is to record all the individual undertakings and assurances given to petitioners and to Parliament in a single document. This is to help ensure that the ‘nominated undertaker’ (any person appointed to construct HS2), the Secretary of State for Transport, or any other organisation exercising the powers provided by the Act complies with them throughout the project’s lifecycle.
The register includes:
all undertakings between petitioners and the Secretary of State for Transport
undertakings given in the High Speed Rail (London to West Midlands) Bill Parliamentary process
assurances given to petitioners in letters from HS2 Ltd, the Department for Transport or HS2 Parliamentary Agents (Winckworth Sherwood and Eversheds) on behalf of the Secretary of State for Transport; and
