Heathrow Airport has been forced to close following a significant power outage, triggered by a large fire at an electrical substation supplying the UK’s busiest airport.
The unprecedented closure comes after a transformer fire at a substation in Hayes, West London, plunged key parts of the airport into darkness and disrupted critical systems.
A formal statement issued by Heathrow Airport confirmed that operations have been suspended until 23:59 on 21 March, with all terminals affected.
Due to a fire at an electrical substation supplying the airport, Heathrow is experiencing a significant power outage. To maintain the safety of our passengers and colleagues, Heathrow will be closed until 23h59 on 21 March,” the airport stated via social media.
Passengers Urged NOT to Travel
Passengers have been urgently advised not to travel to the airport and instead to contact their airlines for updates on flight rescheduling and alternative arrangements.
Scenes of confusion have been reported across terminals, with stranded travellers facing cancelled flights, limited lighting, and halted services including check-in and baggage handling.
Substation Fire Triggers Widespread Disruption
The closure follows a major incident declared by emergency services overnight, after a fire broke out at a substation on Nestles Avenue in Hayes. The blaze, which required ten fire engines and 70 firefighters, has also left over 16,000 homes and businesses without power across Hayes, Hounslow, and surrounding areas.
A 200-metre cordon remains in place around the site, and nearly 150 people have been evacuated as a precaution.
Airport Operations Paralyzed
While air traffic control systems remain operational, the lack of power within the terminals has made it impossible to continue safe passenger operations. All arrivals and departures have been suspended, with many inbound flights diverted to alternative UK airports.
“Our teams are working closely with emergency services and energy providers to restore power as quickly as possible,” Heathrow Airport added. “We understand the frustration this causes and appreciate passengers’ patience as we respond to this unexpected situation.”
Airlines Respond to Crisis
Airlines including British Airways, Virgin Atlantic, and Lufthansa have begun rerouting flights and rebooking passengers affected by the shutdown. Customers are being urged to check directly with their carriers for the latest updates.
