Question to the Department for Transport:

To ask His Majesty's Government whether they will carry out an economic assessment, including a regional analysis, when evaluating rail access to Heathrow Airport as part of expansion proposals.

The Government recognises the vital role that surface access will play as part of any future expansion of Heathrow Airport. As part of the review of the Airports National Policy Statement (ANPS), launched on 22 October 2025, we will consider the transport infrastructure required to support a third runway, including rail connectivity and mode share targets. This will include considering the impacts for travellers from different regions.

The Government has been clear that expansion must be affordable and delivered in the best interest of passengers. Scheme costs should be minimised and financed through private funding, including any surface transport costs.

While it would not be appropriate to pre-empt the outcome of the ANPS review at this stage, it will be the responsibility of any expansion promoter to set out a surface access strategy demonstrating how they will meet the requirements set out in the ANPS.
