London Underground strike action: 21-24 April

Due to planned strike action, there will be little to no service across all London Underground services, including the Piccadilly line to Heathrow, between 21 and 24 April 2026. 

 

Heathrow Express, Elizabeth line, and local bus services will run as normal on these days. Please plan your journey prior to travelling to Heathrow, and allow for extra time where necessary, as these services will be busier than normal.

Cargo Tunnel

Closure update

Cargo Tunnel closure

The Cargo Tunnel is being refurbished and the Project is expected to be completed early in 2026. To facilitate some of the more complex refurbishment activities, including the commissioning of ventilation systems, there is a requirement for the tunnel to be fully closed.

Closure details:

From 22:00 (local time) on Friday 17 October to 05:00 (local time) on Monday 24 November 2025 (inclusive)

During these times, the Cargo Tunnel will be fully closed 24/7, with no access for the airside community. All airport companies must ensure their colleagues are regularly updated and familiarised on the diversionary routes and procedures outlined in Operational Advice Notice (OAN 435).
