To ask the Secretary of State for Transport, what economic analysis her Department has undertaken on expansion at Heathrow.

Answer

Keir Mather

The current Airports National Policy Statement (ANPS) and its supporting documents provide an economic assessment of a new northwest runway at Heathrow.

On 22 October, the Secretary of State for Transport launched a review of the ANPS. As part of the review, the Department for Transport will develop updated analysis on the economic impacts of expansion at Heathrow, and the outputs will be published alongside any amends to the ANPS for consultation by summer 2026. Any promoter will then need to prepare and submit a development consent order, including their own analysis, for expansion for consideration by the Planning Inspectorate and the Secretary of State for Transport.
