The London airport of Heathrow unveiled a firm and ready-to-execute proposal this Friday: the construction of a third runway entirely financed with private capital, which could be operational in less than ten years. This project, valued at £21 billion, represents a direct commitment to the economic growth of the UK and its leadership in global connectivity.
More Flights, Better Prices, and Greater Connectivity
The expansion would allow the airport to handle up to 756,000 flights and 150 million passengers annually, unlocking at least 30 new daily routes and strengthening domestic connections. This will translate into more destination options, better schedules, and more competitive fares, thanks to increased competition among airlines.
Additionally, a complete transformation of the airfield is planned, promising faster takeoffs and more spacious, accessible terminals. The new “T5X” terminal, along with the expansion of Terminal 2 and the construction of three satellite terminals, are part of this ambitious overhaul.
Direct and Distributed Economic Impact
The expansion would add 0.43% to the UK’s GDP, with 60% of that benefit generated outside London and the Southeast. Heathrow, already considered the country’s most valuable port with over £200 billion in annual trade, would increase its cargo capacity by 50%.

The impact will also be felt in employment: tens of thousands of jobs will be created during the design, construction, and operational phases. Sixty percent of the supply chain spending will benefit companies located outside the London metropolitan area, reinforcing the national character of the project.
Environmental Commitment: Carbon, Noise, and Accessibility
Heathrow is not only betting on growth but also on doing so sustainably. The proposal includes:
- A goal to achieve net-zero emissions by 2050.
- A 10% reduction in flight emissions since 2019 and a 15% reduction in ground emissions.
- Promotion of sustainable aviation fuel (SAF) use.
- A 41% reduction in noise footprint since 2006.
- Compliance with air quality limits at all monitoring stations.
Additionally, significant improvements in public transport and airport access will be implemented: increased rail capacity, dedicated cycling and pedestrian routes, a new road tunnel, two dedicated parkways, and upgrades to the busiest bus and coach station in the country.
A Viable, Backed, and Ready Proposal
The plan includes a northwest runway of up to 3,500 meters, an infrastructure already backed by Parliament. Unlike other proposals, Heathrow has years of prior studies and engagement, enabling it to meet government deadlines and begin investments this year, provided the regulatory framework allows it.
Heathrow CEO Thomas Woldbye was emphatic: “It’s now or never. We are operating at capacity, affecting trade and connectivity. If the government gives the green light and provides the right regulatory support, we are ready to take off with investments across the country.”
Timeline and Next Steps
- 2025: Consultation with airlines, local authorities, and the community.
- 2028: Formal submission of the planning application.
- 2029: Expected approval.
- Next decade: Third runway operational.
The project has the backing of chambers of commerce across the country, unions, educators, and construction sector businesses. All agree that this is a historic opportunity to strengthen access to global markets and secure the UK’s economic future.
An Airport at Capacity, a Nation at Risk
Heathrow currently connects British exporters to 92% of the global economy. Without expansion, the UK risks losing its position as an international hub to European competitors with room to grow. This proposal is not just an airport expansion—it is an investment in the country’s future.
