The airport handled over 84.5 million passengers, cementing its position as Europe’s busiest hub airport.
Heathrow is forecasting a small increase for 2026, taking it over 85 million passengers.
Heathrow says despite the numbers, overall flight punctuality improved.
More than four million more passengers flew on time compared with 2024 and baggage and security performance improved too, it says.
Baggage load rates were close to 99% for the year.
The airport will spend £1.3 billion this year on capital investment programmes.
This will kickstart work to revamp Terminal 4, progress with the new baggage system design for Terminal 2 and enhance services for passengers with accessibility needs.
Heathrow reported increased revenue of £3.6 billion but a flat adjusted EBITDA of £2 billion.
Heathrow’s Board decided to pay dividends of £550 million to the ultimate shareholders during the financial year, the first time in five years.
Heathrow 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.”
