Chancellor Healey Backs Heathrow Expansion as Prime Minister Hesitates

Published: October 19, 2026, 12:01 am

Chancellor John Healey has publicly advocated for the expansion of Heathrow Airport, describing the proposed third runway as a fundamental catalyst for economic progress. British Airways planes lined up at Terminal 5 at Heathrow Airport. Currently capped at 480,000 a year, could go up to 720,000 – or nearly 2,000 a day on average, if a third runway is built, the number of flights.

Speaking at the International Monetary Fund in Bangkok, Healey noted that airport capacity projects have historically been central to job creation and national growth.

His remarks highlight a growing tension within the government regarding the multi-billion pound infrastructure project.

Prime Minister Andy Burnham has remained notably more reserved.

Last month, he suggested to the media that the decision should be framed primarily as a matter for London and its residents, rather than a top-down mandate. This cautious approach contrasts with his predecessor, Rachel Reeves, who had previously identified the project as a critical element of the government’s strategy to demonstrate that Britain remains open for international business.

Project Scope and Requirements

  • Estimated Cost: £33bn
  • Current Annual Flight Cap: 480,000
  • Potential Annual Flight Capacity: 720,000
  • Original Planned Opening: 2035
  • Revised Projected Opening: 2039
  • Key Infrastructure Requirements: Demolition of hundreds of homes, diversion of rivers, and rerouting the M25 motorway through a new tunnel.

Heathrow Chief Executive Thomas Woldbye has cautioned that failing to proceed with the expansion represents a significant lost opportunity.

Emphasizing that the benefits extend far beyond the capital, Woldbye pointed out that the airport’s supply chain spans the entire United Kingdom.

He has publicly urged the prime minister to align with the project, noting that the airport currently serves over 80 million passengers annually via its existing two runways and four terminals.

Government and Regulatory Status

  • Consultation Status: Closed; currently under review by the Transport Department.
  • Project Backing: The airport’s consortium has requested explicit confirmation from the prime minister before the end of the year to maintain momentum.
  • Official Stance: Further policy announcements are expected once current reviews are completed.
  • Historical Context: The expansion has been a subject of intense debate for decades, drawing consistent opposition from climate campaigners, local residents, and various political factions.

The Department for Transport is currently evaluating the next steps based on the national policy statement, which serves as the formal framework for authorizing the project. While the development was originally slated for completion by 2035, ongoing regulatory and planning hurdles have pushed the anticipated delivery date to 2039. The project, which has an estimated price tag of £33bn, would see hundreds of homes demolished, rivers diverted and the M25 motorway rerouted through a tunnel between junctions 14 and 15.

Key Job Details

  • And then further decisions and announcements will follow, we’re reviewing those.
  • Asked about the project in September, Burnham suggested it was an argument for London to decide.
  • I think we ought to hear the voice of people there first. It’s not right for me to just jump straight in on the back of the consultation,” he added.
  • According to speaking to Radio 4’s Today programme earlier this week, Woldbye, It would be “good to know” the government’s position on the project.
  • Benefits will be felt all over the country because our supply chain reaches all the way from the north all the way to the south of the UK,” Woldbye said.
