Heathrow Airport Closes Due To Major Power Outage.
Heathrow Airport, the UK’s busiest aviation hub, has been forced to shut down entirely for Friday following a significant power outage caused by a fire at a nearby electrical substation. The disruption is expected to impact thousands of travellers and flights worldwide.
Passengers Warned to Stay Away
The airport has urged passengers not to travel “under any circumstances” until normal operations resume.
“To maintain the safety of our passengers and colleagues, we have no choice but to close Heathrow until 23:59 on 21 March 2025,” a spokesperson confirmed.
While fire crews continue to battle the blaze, there is no clear timeline for when power will be fully restored. “We know this will be disappointing for passengers, and we want to reassure them that we are working as hard as possible to resolve the situation,” the spokesperson added.
Thousands of Flights Affected
According to flight tracking service Flightradar24, at least 1,351 flights to and from Heathrow have been affected, with 120 aircraft already airborne when the closure was announced.
The disruption has forced major airlines to make alternative arrangements. United Airlines confirmed that seven of its flights destined for Heathrow were either turned back or redirected. Qantas also reported that two of its flights had been diverted to Paris.
Stranded Passengers Face Travel Chaos
Travellers across Europe have been left stranded, with many scrambling to find alternative routes. BBC journalist Thomas Mackintosh, among a group of Scotland football supporters in Athens, described the moment their plans were derailed.
“We had cleared passport control and security, only to hear an announcement that all flights to Heathrow were cancelled,” he said. The group, many of whom had planned onward journeys to Edinburgh, Glasgow, or Aberdeen, were forced to re-enter Greece and consider costly re-bookings via other European cities.
Fire Causes Widespread Blackout in London
The fire broke out at an electrical substation in Hayes, West London, late on Thursday night, triggering a large-scale power outage that left over 16,300 homes in darkness. Emergency services were called at 23:23, with footage on social media showing towering flames and thick smoke billowing from the site.
London Fire Brigade (LFB) deployed ten fire engines and 70 firefighters to tackle the blaze, which had engulfed half of a transformer by early Friday morning.
Assistant Commissioner Pat Goulborne described the incident as “highly visible and significant,” warning that it would be a “prolonged operation” with firefighters on-site throughout the night. A 200-metre cordon has been established as a safety measure, and residents have been advised to keep their doors and windows shut due to heavy smoke.
Uncertainty Over When Heathrow Will Reopen
As authorities work to restore power, the cause of the fire remains unknown. The incident has raised concerns over the vulnerability of key infrastructure and the ripple effect of power failures on major transport hubs.
Heathrow has apologised for the disruption and advised affected passengers to contact their airlines for further updates. With thousands stranded and uncertainty looming, the full impact of the closure is yet to be realised.
