Heathrow unveils T4 overhaul as part of £1.3bn investment 

Heathrow has unveiled a series of upgrades totalling £1.3bn to be made to the airport throughout 2026.

Construction will start on a revamp of Terminal 4 which will include the development of a new multi-storey car park and upgraded check-in area.

The airport said the work, expected to be completed in 2031, will be phased to “ensure T4’s current operations run as normal”.  

Work will also begin on a new dedicated baggage system for Terminal 2 which will enable “much more resilient and efficient services for airline customers”, capable of handling 31,000 bags per day.

“It will also further reduce costs for airlines who will have fewer misconnected bags to reunite with passengers,” said a spokesperson.

A new network of cameras is also being installed across Heathrow’s stands which will use AI to analyse captured data, which Heathrow said will “speed up turnaround times” between flights.

There will also be investment in facilities for passengers with accessibility needs, including the creation of a new purpose-built assistance area in Terminal 2. 

Heathrow chief executive Thomas Woldbye said: “I’m excited to unveil next year’s programme [of upgrades] which will make Heathrow more user-friendly, more efficient and more resilient for our customers. 

“This investment will flow directly into our nationwide supply chain helping to drive economic growth while we make Heathrow even better and more efficient for our customers.”
