HS2 Forthcoming Works Packages for submission to Buckinghamshire Council

Schedule 17 of the HS2 Act puts in place a process for the approval of certain matters relating to the design and construction of the railway, which requires that the nominated undertaker (HS2 Ltd and its contractors) must seek approval of these matters from the relevant planning authority. As deemed planning permission has been granted by the Act, requests for approval under Schedule 17 are not planning applications and there are few grounds on which the Council can refuse.

Forecast dates are subject to slippage to contractors.
