Heathrow Airport: Construction

The question

To ask the Secretary of State for Transport, when she expects the (a) economic and (b) environmental analysis of Heathrow Airport expansion to (i) commence and (ii) be completed.

Answered by Keir Mather

On 22 October, the Secretary of State for Transport launched a review of the Airports National Policy Statement (ANPS), which provides the primary basis for decision-making on whether to grant development consent for a new northwest runway at Heathrow. As part of the review, the Department for Transport will develop analysis on the economic and environmental 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.
