Heathrow Confirms £1.3 Billion Investment Programme for 2026 Upgrades
Heathrow Airport has confirmed plans to invest £1.3 billion in 2026 as part of its ongoing five-year capital programme, following operational improvements delivered in 2025. The investment is aimed at enhancing passenger experience, operational efficiency, resilience, and accessibility, while supporting the airport’s supply chain across the UK.
Key projects planned for 2026 include the start of a major refurbishment of Terminal 4. The redevelopment will introduce a new multi-storey car park and an upgraded check-in area. Construction will be carried out in phases to ensure current operations continue uninterrupted, with completion expected by 2031.

Work will also begin on a new dedicated baggage handling system for Terminal 2. Once operational, the system will process up to 31,000 bags per day, improving reliability and reducing misconnections while supporting more efficient airline operations.
As part of its technology upgrades, Heathrow is rolling out a new network of cameras across aircraft stands. Using AI-driven data analysis, the system is designed to improve aircraft turnaround times in collaboration with airlines and ground handling partners. Full coverage across all terminals is expected by the end of 2026.

Accessibility remains a focus area within the 2026 investment programme. Heathrow will introduce a new purpose-built assistance area in Terminal 2, providing direct access to security for passengers requiring support. Additional upgrades will be made to assistance areas across the airport, alongside the introduction of new mobility equipment. The airport will also launch a Tailored Travel Guide, allowing passengers with access needs to receive personalised, step-by-step guidance for navigating their journey through the airport.
Commenting on the announcement, Heathrow CEO Thomas Woldbye said the investment builds on progress made in operational performance over the past year, including improvements in punctuality, baggage handling, and security processing times. He added that the 2026 programme is intended to make Heathrow more efficient and accessible while supporting economic activity through its supply chain.
The investment forms part of Heathrow’s current five-year regulatory settlement, known as H7. Separately, proposals for a third runway and investment plans for the subsequent 2027–2031 period (H8) remain subject to government policy decisions and the regulatory framework set by the Civil Aviation Authority.
