Chancellor John Healey stated that expanding Heathrow Airport with a third runway has "always been a case for growth", following recent comments from Prime Minister Andy Burnham that declined to offer a specific endorsement. Speaking at International Monetary Fund meetings in Bangkok, Healey described airport expansion as a big part of jobs and growth over recent decades.
The project has faced long-standing debate involving local residents, politicians, and climate campaigners. While former Chancellor Rachel Reeves previously described the third runway as "badly needed," Burnham recently characterized the expansion as a matter for London and its residents to decide.
Heathrow Chief Executive Thomas Woldbye said earlier this week that failing to build the runway would be a "huge missed opportunity." Woldbye stated that the project’s benefits would reach beyond London due to a nationwide supply chain. The Department for Transport is currently considering the appropriate next steps following a recently closed public consultation on the National Policy Statement, which provides the basis for deciding whether to grant the new runway.
For the traveling public and the aviation industry, the expansion would increase the annual flight cap from 480,000 to 720,000, averaging nearly 2,000 flights per day. This represents a 50% increase in capacity for the UK's busiest airport. However, the timeline for these changes has shifted. While the runway was originally scheduled to open by 2035, Heathrow has since suggested it would be delayed by four years to 2039, citing ongoing planning and regulatory issues.
The decision carries significant weight for Heathrow’s consortium of owners, who have stated they require explicit backing from the Prime Minister before the end of the year to proceed. The government's final determination will set a precedent for how major infrastructure projects balance national economic goals against local environmental and community concerns. Following the Department for Transport's review of the consultation, the government is expected to issue further announcements regarding the project.
