Heathrow will unleash a £1.3bn improvement drive in 2026 as the airport kicks off a long-awaited overhaul of Terminal 4 and pushes ahead with major upgrades across its estate.
Construction on the T4 revamp will begin with a new multi storey car park and an upgraded check in hall. The work will run in phases to keep the terminal operating normally and is expected to complete in 2031.
Heathrow will also start building a dedicated baggage system for Terminal 2 capable of handling 31000 bags a day and reducing airline costs by cutting misconnected luggage.
