Heathrow permitted to pass £320m in early expansion costs onto passengers

The Civil Aviation Authority has granted Heathrow Airport Limited permission to recover £320 million spent on early third-runway expansion plans. The regulator will allow the airport operator to recoup these funds through increased airline charges over the next two to three decades.

This decision translates to a maximum airport charge increase of roughly 15p per passenger in 2028, rising to an estimated 30p in subsequent years. For Europe’s busiest aviation hub, the move highlights the immediate financial mechanics of major infrastructure projects and their direct impact on consumer pricing.

The approval has drawn sharp criticism from airlines, which already argue that Heathrow imposes the highest airport charges globally. British Airways, the airport's largest carrier, warned in a regulatory document that early cost recovery creates a risk that expansion would be “unaffordable for consumers and inconsistent with a credible benefits case”.

The recoverable funds specifically cover planning and design work required to develop a credible proposal and support a future development consent order application. Meanwhile, a rival proposal called Heathrow West, led by property billionaire Surinder Arora, received approval to recover £4.1 million spent on its own plan in 2025. This rival funding is capped at 25 November, the date the government selected Heathrow Airport Limited’s scheme as its preferred option.

Defending the ruling, Tim Johnson, the regulator's director of consumers and markets, said: “Our decision strikes a balance between supporting the delivery of benefits to consumers through timely progress on Heathrow expansion, whilst also protecting them from undue increases in costs.” He noted that the recoverable funds are capped and subject to efficiency reviews to ensure passengers only pay for justified expenses. A separate regulatory process will determine arrangements for costs incurred from 2027.

The financial framework arrives as the government advances the physical project. Last month, ministers launched a consultation on the national policy statement outlining conditions for the expansion to proceed. Then-chancellor Rachel Reeves previously stated her determination to get “spades in the ground” for the third runway during the current parliament, targeting a 2035 completion date.

However, the massive capital commitment continues to spark debate over regional economic equity. Andy Burnham has publicly argued that the Heathrow expansion diverts infrastructure investment “away from the north and traps it in London”, underscoring the broader political friction surrounding major transport investments.
