Heathrow is a vital piece of infrastructure at the heart of both the London economy and the UK’s prosperity. As the country’s only hub airport, Heathrow plays a unique role in connecting London, and indeed the whole country, to overseas markets, supporting trade, investment and economic growth.
Each year, Heathrow helps more than 84 million passengers travel to and from over 230 destinations worldwide. These connections are fundamental to maintaining London’s position as one of the leading global cities, supporting its renowned business, cultural and tourism sectors while enabling people and businesses to reach customers, suppliers and opportunities overseas.
But Heathrow is much more than an airport. As Britain’s largest port by value of trade and the UK’s largest single-site employer, it is an economic hub in its own right. Over 80,000 people work on-site every day, and the airport is a catalyst for investment, employment and enterprise across neighbouring areas of West London and the Home Counties.
Heathrow also plays a critical role in the UK’s transport network. It connects passengers and businesses from across the UK to long-haul destinations around the world, with its route network providing access to 92% of global GDP. This connectivity is essential for British exporters, inward investors and industries that rely on fast and reliable access to customers and trading partners internationally.
This success has been achieved despite significant capacity constraints. While London competes with major cities such as Paris, Amsterdam, Frankfurt and Madrid, their hub airports benefit from four or more runways, compared with Heathrow’s two. Heathrow continues to operate as Europe’s most punctual airport, but without additional capacity, there is an increasing risk that London and the UK will lose ground to competitors, with consequences for connectivity, investment and long-term prosperity.
That is why Heathrow’s £33 billion expansion programme is so important. Entirely privately financed, the project will deliver a third runway, alongside new terminal capacity and supporting infrastructure – representing one of Europe’s largest privately funded infrastructure projects. Expansion will send a clear signal that the UK is open for business, welcoming investment and committed to strengthening its position as a world-leading connected economy.
The economic benefits will be substantial. Expansion will increase Heathrow’s capacity to serve up to 150 million passengers each year and boost cargo capacity by 50%, strengthening the airport’s role as a gateway for trade and investment. The project will unlock economic opportunities across aviation, construction, logistics, engineering, technology and professional services, supporting businesses locally and across the UK.
The programme will also create tens of thousands of jobs during construction and operation. Heathrow already works with more than 1,000 businesses across every nation and region of the UK through its supply chain, and expansion will generate an unrivalled chance for firms of all sizes to participate.
Skills development will be central to delivering these benefits. Building and operating an expanded Heathrow will require a new generation of workers with expertise in engineering, construction, aviation operations, digital technology, sustainability and logistics. The project presents a major opportunity to expand entry-level training, develop technical skills and create high-quality careers for people, helping to build a workforce ready to power the industries and jobs of the future.
With private investment secured, the final step is securing government approval. A parliamentary vote later this year represents a pivotal moment for the project and the wider economy. A positive decision would unlock tens of billions of pounds of private capital and provide a generational boost to jobs, skills, connectivity and economic growth.
By expanding Heathrow, the UK can strengthen its global competitiveness, enhance its trading relationships and secure long-term economic success. With the right support in place, Heathrow can continue to connect people, businesses and markets while driving sustainable jobs, investment and connectivity for London and the wider UK for decades to come.
