Heathrow Airport has issued a passenger warning after flooding in the central terminal area blocked road access to Terminals 2 and 3. Passengers travelling to or from either terminal today are being told not to travel by road and to use rail and underground services instead.
Pipe leak causes road closures
On August 15, Heathrow posted an update on its website and social media, stating that a pipe leak has blocked road access to the two terminals and advising passengers to allow extra time for their journeys. The terminals serve many popular destinations in Europe, North America, Asia, and the Middle East during the busy summer holiday season.
The airport's website update read: “Flooding in the central terminal area has resulted in on-going road closures restricting access to Terminals 2 and 3. Passengers travelling to or from either of these terminals today must not travel by road.” It added that passengers are “strongly advised to use Heathrow Express, Elizabeth Line and Piccadilly Line rail services where possible.”
Alternative travel arrangements
Passengers who need to travel by car are being told to use Park and Ride, “head to Terminals 4 or 5 and take free rail services from there, or change at local rail stations. Please allow extra time for your journeys.” The airport also said, “Our teams are working to resolve the situation as quickly as possible, we apologise for any disruption caused.”
This disruption follows delays and diversions at Heathrow last week due to a grass fire near one of the runways.
Passenger queries and response
Passengers have turned to social media for answers after the airport posted an update on X at 5:39am on August 15. One user asked, “Will this take the whole day today? I am flying on a night flight. Do you have an estimate?” A Heathrow representative replied: “Regrettably we would not have any information currently, our teams are on the ground working hard to resolve the issues. Any updates will be on our website and social media. Apologies for the inconvenience.”
Another passenger, Helen, asked about accessing a car parked in official airport parking at T2/T3. A representative replied: “Hi Helen, we are currently waiting for further updates, please watch this space.” Jaspreet, who paid £300 for parking, asked what to do. Heathrow replied: “Hi Jaspreet, we understand your concern. For now we recommend heading to T5 M&G and explaining to staff that your booking has been affected by the flooding. Please be assured our teams are working to resolve the situation as quickly as possible, so please watch this space for further updates.”
It is currently unclear when the roads around Terminals 2 and 3 will reopen or what arrangements will be made for passengers with cars parked in affected areas. Heathrow has advised passengers to keep checking its website and social channels for updates.
