The Association for Consultancy and Engineering (ACE) has welcomed government backing for Heathrow Airport's £49bn third runway expansion plan.  

A third runway at Heathrow is another step closer to take off by 2035, as the Transport Secretary Heidi Alexander confirmed that Heathrow Airport Limited’s (HAL’s) proposal will be used as the scheme to progress the project.

The proposal will shape the review of the Airports National Policy Statement (ANPS), which is the framework within which the planning decision on expansion at the airport will be made, and any amendments to the ANPS will be subject to consultation next summer.

At the heart of HAL's proposal is a £21bn third runway, entirely privately funded, which will unlock new routes, boost UK trade and expand capacity at the country’s most important global gateway.

ACE Director of Public Affairs, Ben Brittain, said: “The government’s decision to advance Heathrow’s third runway proposal is the right one, providing long-needed clarity and momentum.

“A project of this scale will rely on disciplined design, engineering excellence and timely delivery, ensuring that the expansion strengthens the UK’s competitiveness while meeting environmental obligations. With a clear path now set, this is a significant opportunity to deliver infrastructure that supports growth, enhances connectivity and underpins the country’s long-term economic ambitions.”
