Question to the Department for Transport:

To ask the Secretary of State for Transport, what plans he has to assess the effect of the three year delay to Heathrow's third runway on the economic benefits of that scheme.

The Airports National Policy Statement sets out that there is a need to increase airport capacity in the South East of England by 2030 by constructing one new runway and that this need is best met by the Northwest Runway scheme at Heathrow Airport.

Heathrow Airport Limited (HAL) have confirmed that they intend to submit an application for development consent in 2020 which, if approved by the Secretary of State, following a report from the Planning Inspectorate, would allow for the construction and the opening of a third runway between early 2028 and late 2029.

Given that the delivery of any major infrastructure scheme is subject to uncertainty, prior to the designation of the Airports National Policy Statement, the Department for Transport undertook scenario and sensitivity testing which included an assessment of the impacts of a two-year delay on the delivery of the three schemes shortlisted by the Airports Commission, this was from 2025 in the case of Gatwick Airport and 2026 in the case of the two Heathrow schemes. The case for the Northwest Runway was not materially changed by such a delay. Furthermore, such a delay would serve to similarly reduce the schemes’ disbenefits, partially offsetting the reduction in direct economic benefits.
