Question to the Department for Transport:

To ask the Secretary of State for Transport, if she will make an estimate of the potential planning costs for the delivery of a third runway at Heathrow.

The Government recognises the importance of making sure that any scheme for Heathrow expansion is both deliverable and affordable. It is for potential promoters to develop plans for expansion as part of their Development Consent Order application. As the independent economic regulator for expansion, the Civil Aviation Authority (CAA) will determine the recovery of costs incurred by potential promoters of expansion.
