The London Fire Brigade says the electrical substation blaze that closed Heathrow Airport is under control.
The fire caused a widespread power outage, affecting thousands of homes and local businesses and disrupting thousands of flights.
Assistant Commissioner Pat Goulbourne announced just after 8 a.m. Friday that the fire was under control.
“This was a very visible and significant incident, and our firefighters worked tirelessly in challenging conditions to bring the fire under control as swiftly as possible,” he said. “Thanks to their efforts and coordinated multi-agency response, we successfully contained the fire and prevented further spread.”
At least 1,350 flights to and from Heathrow were affected, flight tracking service FlightRadar 24 said, and the impact was likely to last several days as passengers try to reschedule their travel

Some 120 flights were in the air when the closure was announced, with some turned around and others diverted to Gatwick Airport outside London, Charles de Gaulle Airport in Paris or Ireland’s Shannon Airport, tracking services showed.
Lawrence Hayes was three-quarters of the way to London from John F. Kennedy International in New York when Virgin Atlantic announced they were being diverted to Glasgow.
“It was a red-eye flight and I’d already had a full day, so I don’t even know how long I’ve been up for,” Hayes told the BBC as he was getting off the plane in Scotland. “Luckily I managed to get hold of my wife and she’s kindly booked me a train ticket to get back to Euston, but it’s going to be an incredibly long day.”
Heathrow said in its statement it will provide an update on its operations when it has more information on when power will be restored.
“To maintain the safety of our passengers and colleagues, we have no choice but to close Heathrow” for the full day, the airport said. “We expect significant disruption over the coming days, and passengers should not travel to the airport under any circumstances until the airport reopens.”
Heathrow is one of the world’s busiest airports for international travel. It had its busiest January on record earlier this year, with more than 6.3 million passengers, up more than 5% from the same period last year. January also was the 11th month in a row that it averaged over 200,000 passengers a day, with the airport citing trans-Atlantic travel as a key contributor.
The disruption was reminiscent of 2023 delays that hit U.K. airports when Britain’s air traffic control system was hit by a breakdown that slowed takeoffs and landings across the country on one of the busiest travel days of the year.
United Airlines said seven of its flights returned to their origin or diverted to other airports and its flights Friday to Heathrow were canceled.
At least two flights from Taiwan to London were affected, the island’s Central News Agency reported. A China Airlines flight that left in the morning turned around and was headed back to Taiwan. An EVA Air flight stopped in Bangkok, a planned stopover, while the airline assessed the situation in London.
Singapore Airlines said on the X social media platform that its overnight flight to London was diverted to Frankfurt.
The FlightAware website showed more cancellations, including two from JFK in New York, a Delta Airlines flight and an American Airlines flight.
National Rail canceled all trains to and from the airport.
The London Fire Brigade had 10 fire engines and around 70 firefighters worked to control the blaze hours after flames soared into the sky when a transformer at an electrical substation caught fire in west London late Thursday night. The fire continued to smolder after daybreak.
Thousands of homes also lost power and about 150 people were evacuated.
Footage posted to social media showed huge flames and large plumes of smoke coming from the facility.
“The fire has caused a power outage affecting a large number of homes and local businesses, and we are working closely with our partners to minimize disruption,” Assistant Commissioner Pat Goulbourne said.

Scottish and Southern Electricity Networks said in a post on X the power outage affected more than 16,300 homes.
Emergency services were called to the scene at 11:23 p.m. Thursday. The cause of the fire is yet to be determined.
Goulbourne urged people to take safety precautions and avoid the area as crews worked to extinguish the blaze.
Heathrow normally opens for flights at 6 a.m. due to nighttime flying restrictions. It said the closure would last until 11:59 p.m. Friday.
The U.K. government earlier this year approved building a third runway at the airport to boost the economy and connectivity to the world.
