Heathrow Unveils £1.3bn Investment Plan for 2026

Heathrow Airport has announced a £1.3 billion investment programme for 2026, aimed at improving passenger experience, operational resilience and accessibility, while supporting its UK-wide supply chain. The announcement follows a strong 2025, during which Heathrow delivered record growth and was named the most punctual hub airport in Europe.

 

The investment will kick off a major revamp of Terminal 4, including a new multi-storey car park and upgraded check-in facilities. Construction will be phased to ensure uninterrupted operations, with completion expected by 2031.

Work will also begin on a new dedicated baggage system for Terminal 2, designed to handle up to 31,000 bags per day. Once operational, the system will improve reliability, reduce mishandled baggage and lower costs for airlines by minimising misconnected bags.

Across the airfield, Heathrow is rolling out a network of AI-enabled cameras at aircraft stands. By analysing turnaround data in real time, the system helps airlines and ground handlers reduce delays, improve efficiency and enhance punctuality. Full coverage across all terminals is expected by the end of 2026.

Accessibility remains a key focus of the 2026 programme. Heathrow will open a new purpose-built assistance area in Terminal 2, offering direct and dedicated access to security for passengers with reduced mobility. Additional investments include new mobility equipment and upgrades to assistance areas across the airport. Heathrow will also introduce its Tailored Travel Guide, the first of its kind at a UK airport, providing personalised, step-by-step journey guidance for passengers with access needs.

Heathrow CEO Thomas Woldbye said the airport’s goal is continuous improvement for passengers, highlighting that nearly 99% of bags travelled on the correct flight, 97% of security waits were under five minutes, and next-generation security will be available in all terminals by January.

The announcement forms part of Heathrow’s current H7 five-year investment programme. Separate from this, future expansion plans, including a potential third runway and the next investment period from 2027 to 2031, will depend on government and regulatory decisions.
