Heathrow airport reports lower profit in first nine months of 2025

(Alliance News) - The operator of Heathrow airport in west London on Wednesday reported higher revenue but lower profit in the first nine months of the year, confirming it expects to handle more passengers in all of 2025 than in 2024.

Heathrow (SP) Ltd reported GBP217 million in adjusted pretax profit in the nine months that ended September 30, down 38% from GBP350 million a year before. Adjusted earnings before interest, tax, depreciation and amortisation was GBP1.53 billion, down 0.2% from GBP1.54 billion.

Revenue in the first three quarters was GBP2.70 billion, up 2.0% from GBP2.65 billion, while adjusted operating costs were GBP1.17 billion, up 5.0% from GBP1.11 billion. Heathrow said the higher revenue was thanks to strong long-haul flying, increased uptake of premium services, and positive property valuations. The higher expenses were due to increase security compliance and higher UK National Insurance costs.

The airport handled 63.3 million passengers in the first nine months of 2025, up 0.3% from 63.1 million a year before. It handled 23.4 million in the third quarter and more than 8 million in August alone.

Heathrow said its expects 2025 passenger demand to outstrip 2024.

It said it took practical steps toward its 'net zero' carbon emission plan in the third quarter, including a new air system in Terminal 5 that will improve air quality and reduce carbon emission on 11 stands.
