CAA Greenlights Heathrow Passenger Levies to Fund Expansion

• Civil Aviation Authority permits Heathrow to recoup £320 million in preparatory costs.
• Travellers face fare increases of 15p in 2028, rising to 30p in later years.
• Total project costs for the third runway are estimated between £33 billion and £49 billion.
• The new runway is currently aimed for completion and operation by 2035.

The Civil Aviation Authority (CAA) has granted Heathrow Airport Limited (HAL) permission to recover £320 million in early development costs related to its third runway expansion. This financial provision is intended to cover essential planning, design, and preparatory work conducted throughout 2025 and 2026. The decision marks a significant step in the long-term infrastructure project, ensuring that the airport can finance the initial stages of its growth strategy.

As a result of this regulatory decision, passengers using the London hub can expect to see a direct impact on airfares in the future. Airline charges are projected to rise by roughly 15p per passenger starting in 2028, with the figure anticipated to increase to approximately 30p in subsequent years. These costs are set to be reclaimed via higher airline fees, which carriers traditionally pass on to travellers through ticket pricing. The cost recovery process is expected to span a period of 20 to 25 years.

According to reports in The Mirror, the UK government officially selected the HAL proposal as its preferred option for expansion on 25 November 2025. The overall project carries a significant financial burden, with total costs estimated to fall between £33 billion and £49 billion. A major component of the infrastructure plan includes the relocation of a section of the M25 motorway, an undertaking projected to cost £1.5 billion alone.

While the government and airport owners aim for the third runway to be operational by 2035, the decision has met with resistance from industry figures. British Airways, the largest operator at Heathrow, has expressed concerns that early cost recovery could make the expansion project unaffordable for consumers. This comes as airlines continue to argue that Heathrow already maintains some of the highest landing and service charges of any airport globally.

In addition to the allowance for HAL, Heathrow West Limited—a rival expansion project led by billionaire Surinder Arora—was also granted permission to recoup £4.1 million in development costs. Tim Johnson, the CAA’s director of consumers and markets, explained that the decision is intended to strike a balance between making timely progress on expansion and protecting the financial interests of passengers through various safeguards.

To protect consumers, the CAA has confirmed that all expenditure will be subject to independent scrutiny and efficiency reviews. A public consultation on the Heathrow Expansion National Policy Statement (HENPS) is currently scheduled to remain open until 1 September 2026, with a final planning decision not expected until 2029. Chancellor Rachel Reeves has previously voiced strong support for the project, describing it as critical to national growth and indicating a determination to get work started on the ground.

Tom Church, Co-Founder of LatestDeals.co.uk, said, "While the individual cost per passenger appears small, travellers should stay informed about how these long-term infrastructure levies may contribute to the rising cost of air travel over the coming decades."
