Question to the Department for Transport:

To ask the Secretary of State for Transport, what estimate her Department has made of how many people will be exposed to noise pollution from aircraft above 51 decibels as a result of expansion at Heathrow.

As part of the review of the Airports National Policy Statement (ANPS) the Government will develop updated assessments of the noise and air quality impacts of expansion at Heathrow and will review and update the existing appraisal of sustainability and health impact analysis in line with any amendments made to the ANPS.

We expect to publish any revisions to the ANPS for consultation by summer 2026, together with supporting assessments.
