Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the accuracy of the estimate of surface access costs associated with an expansion of Heathrow Airport produced by (a) the Airports Commission and (b) the Mayor of London in his response to the Airports Commission consultation, published in February 2015.

The Airports Commission, in undertaking its work consulted widely, engaging with a broad range of organisations and people, and considered a wide range of views and information from stakeholders, including the Mayor of London, to inform its recommendations.

The Government is currently considering the large amount of very detailed analysis contained in the Airports Commission’s final report, including its examination of the costs of the surface access proposals associated with airport expansion, before taking any decisions on next steps.
