Heathrow Airport has closed road access to Terminals 2 and 3 after a burst pipe caused significant flooding in the central terminal area on 15 August 2026. Passengers travelling to or from those terminals cannot do so by car and are being urged to use rail or Tube services instead while repair crews work on the site.
An airport spokesperson said the leak had been contained and that engineers were addressing the resulting damage.
Our teams are working to resolve the situation as quickly as possible, we apologise for any disruption caused.
The leak has been isolated and repairs are on-going.
According to a national broadcaster's report, the flooding has forced ongoing road closures around the two terminals, with travellers advised against driving and encouraged to rely on rail links instead.
How can passengers still reach the airport?
Those who have no choice but to travel by car have been told to use the Park and Ride facility or route via Terminals 4 or 5, according to a report from a national newspaper. From there, free rail connections can be used to complete the journey. The same report notes that Heathrow's guidance specifically directs affected passengers towards the Heathrow Express, the Elizabeth Line and the Piccadilly Line as the preferred alternatives to driving.
Why is this happening now?
The timing is particularly disruptive because it falls during the school summer holidays, traditionally one of the airport's busiest stretches. Heathrow recorded its busiest day of the year so far on 19 July 2026, when 267,000 passengers passed through as many schools broke up for summer.
Heathrow has said the road restrictions stem from flooding across the wider central terminal area rather than being confined to the terminal buildings themselves, according to the same broadcaster's report.
Has this happened before?
This is not the first time flooding or water-related faults have disrupted travel to and from the airport. A burst pipe in May 2026 shut rail services to Heathrow for several hours, and a separate incident in June 2026 also caused disruption specifically around Terminals 2 and 3. More recently, the airport was affected by a water leak that forced the closure of a rail tunnel, disrupting train services serving the site.
What happens next?
Heathrow said its teams were continuing to work to resolve the situation as quickly as possible, though no confirmed timeframe for reopening road access has been given, according to the newspaper report. The airport also said it was still investigating the cause of the flooding and assessing the extent of damage to ensure its facilities remain safe, with further updates expected as repairs progress.
