Heathrow sets passenger record as expansion plans gather pace

London’s Heathrow Airport has reported record passenger numbers and strong operational performance for the year ended 31 December 2025, as momentum builds behind plans for expansion.

The UK hub welcomed more than 84.5 million passengers in 2025, its busiest year to date, retaining its position as Europe’s largest hub airport. A further increase to 85 million passengers is forecast for 2026, with demand continuing to test the limits of existing infrastructure.

Operationally, Heathrow was named Europe’s most punctual hub in 2025, outperforming its major competitors. More than 4.2 million additional passengers travelled on time compared with 2024. Security performance also improved, with 97.3% of passengers waiting less than five minutes, while baggage load rates reached almost 99%.

Capital investment of £1.3 billion is planned for 2026, including works to modernise Terminal 4, progress a new baggage system for Terminal 2, and enhance accessibility services.

Expansion remains central to the airport’s long-term strategy. Shareholders have approved new investment to advance the planning application process for a third runway. Key regulatory decisions are expected in 2026, including a parliamentary vote on the Airports National Policy Statement, enabling development consent order approval by 2029. First flights from a third runway could operate within a decade.

Revenue rose to £3.6 billion, with adjusted earnings before interest, taxes, depreciation, and amortisation steady at £2 billion. Liquidity stood at £2.9 billion and £550 million in dividends were paid.

CEO Thomas Woldbye said: “Last year everyone at Heathrow rallied behind our ambition to deliver exceptional operational performance for our customers. Not only did we meet that goal, we surpassed it and achieved record-breaking service levels.”
