Flooding at Heathrow Airport on August 15, 2026, caused by a burst water main beneath Inner Ring Road West, has forced road closures that restrict access to Terminals 2 and 3 within the Central Terminal Area (CTA).
The flood disruption affects the network of roads serving Terminals 2 and 3 and surrounding buildings but has not reached inside the terminals themselves. As a result, flights operating from these terminals have not been affected according to statements from Heathrow Airport.
Passenger Transport Options and Travel Advice
Passengers travelling to or from Terminals 2 and 3 have been advised to avoid using road transport due to the flooding
and resultant closures. Instead, Heathrow Airport recommends the use of rail services, including the Heathrow Express, the Elizabeth Line, and the Piccadilly Line, which connect these terminals to central London and other points.
Those who must arrive by car are directed to use the Park and Ride facilities located at Terminals 4 and 5. From there, free rail services provide access to Terminals 2 and 3. Travelers are urged to allow additional time for their journeys given the limited road access and ongoing disruption.
Heathrow Airport Response and Context
A spokesman for Heathrow Airport confirmed their teams are actively working to resolve the flooding beneath
Inner Ring Road West. The road closures remain in effect as the repair and drainage efforts continue. The airport has apologized for the inconvenience caused.
This disruption comes during the peak summer travel period, coinciding with the school holidays when passenger volumes are typically high. Heathrow Airport continues to monitor the situation closely to minimize impact on passenger movement and airport operations.
