A catastrophic fire at a nearby electrical substation has forced London’s Heathrow Airport (LHR) to shut down completely today, causing unprecedented travel disruption across global aviation networks. The closure, expected to last until midnight, has already resulted in more than 1,000 flight cancellations and affected nearly 300,000 passengers.

Airport Operations Halted After Substation Fire

Heathrow Airport, one of the world’s busiest international hubs, ceased operations early Friday morning following a major power outage caused by a fire at the North Hyde electrical substation in Hayes, west London. The blaze, which began around 11:30 p.m. Thursday night, knocked out primary power systems and two backup generators, leaving the airport without sufficient power to maintain safe operations.

Airport authorities announced the facility would remain closed throughout Friday, with operations expected to resume after 11:59 p.m. local time. However, industry experts warn that disruptions will likely continue for several days as officials work to restore full power and normalize flight schedules.

“This is an unprecedented situation requiring immediate action to ensure passenger safety,” a Heathrow spokesperson said. “We’re working closely with emergency services and power providers to restore operations as quickly as possible.”

Global Air Travel Disrupted

The sudden closure has sent shockwaves through the global aviation network. According to flight tracking service Flightradar24, at least 1,351 flights have been affected, with numerous aircraft diverted to alternative airports across Europe.

When the shutdown was announced, approximately 120 aircraft were en route to Heathrow, forcing pilots to quickly reroute to other destinations including:

  • London Gatwick
  • Amsterdam Schiphol (which received seven diverted flights)
  • Shannon, Ireland
  • Paris Charles de Gaulle
  • Frankfurt
  • Washington Dulles
  • Reykjavik
  • Helsinki
  • Birmingham
  • Manchester

Several transatlantic flights from cities including Toronto, Atlanta, Bridgetown, Boston, Orlando, and Newark were diverted to Shannon Airport in Ireland. Other U.S.-bound flights turned around mid-journey and returned to their departure points, adding to the confusion and logistical challenges.

British Airways, which operates about 340 flights daily from Heathrow, has been particularly affected. The airline advised passengers not to travel to the airport until further notice, as rebooking options remain limited.

Impact Beyond Aviation

The substation fire’s impact extends well beyond the airport grounds. Initially, approximately 100,000 homes in west London lost power overnight. While utility companies have restored service to most residences, nearly 5,000 homes remained without electricity as of Friday morning.

The incident also forced the closure of six local schools in Hayes:

  • Nestles Avenue Early Years Centre
  • Pinkwell Children’s Centre
  • Pinkwell Primary School
  • Botwell House Catholic Primary School
  • Dr Triplett’s Church of England Primary School
  • The Global Academy

Local services including refuse and recycling collections have been disrupted as well, according to announcements from Hillingdon Council.

The fire itself required the response of approximately 70 firefighters and led to the evacuation of 150 people. Authorities established a 650-foot safety cordon around the affected area.

Economic Fallout and Investigation

Financial markets reacted swiftly to the news, with shares in IAG (British Airways’ parent company) dropping approximately 2.5% in morning trading. Air France-KLM shares also fell about 2%, reflecting investor concerns about the broader economic impact on the aviation industry.

The London Fire Brigade reported having the fire under control by 6:30 a.m. Friday, though crews remained on scene to ensure safety. The Metropolitan Police, including counter-terrorism units, have launched an investigation into the cause of the fire, though officials have emphasized there is currently no evidence suggesting foul play.

UK Energy Secretary Ed Miliband described the fire as “catastrophic” and stated that emergency teams are working to reconnect backup electrical supplies.

Prime Minister Sir Keir Starmer acknowledged the significant disruption in a statement: “I understand the distress and inconvenience this situation is causing for thousands of travelers. I want to thank our emergency services for their swift response and assure the public that I am receiving regular updates as we work to restore normal operations.”

What Travelers Should Know

Airport officials have advised:

  • Do not travel to Heathrow Airport until further notice
  • Contact your airline directly for information about rebookings and cancellations
  • Be aware that the Heathrow Express is running fewer trains and not accepting passengers traveling to the airport
  • Expect continued disruption even after the airport reopens, as airlines work to reposition aircraft and crew

Transport Minister Heidi Alexander urged affected passengers to remain patient: “This is an extraordinary circumstance affecting hundreds of thousands of travelers. We ask for understanding as airlines and airport staff work tirelessly to restore service.”

Long-Term Implications

This shutdown represents the most significant disruption to Heathrow’s operations in at least two decades, according to industry analysts. The incident highlights the vulnerability of critical infrastructure and may have long-term implications for Heathrow’s operational resilience planning, particularly as the airport moves forward with expansion plans including a controversial third runway.

Aviation experts suggest the recovery will be complex, involving not just power restoration but the massive logistical challenge of repositioning aircraft and crew around the world, a process that could take several days to fully resolve.

For now, travelers are advised to monitor airline communications closely and prepare for potential changes to their travel plans through the coming week.
