Heathrow Airport dwell updates: London’s greatest airport will probably be SHUT all day on Friday after huge energy reduce following substation blaze

Heathrow Airport will be closed all day on Friday – with all flights in and out cancelled.

London‘s biggest terminals have been forced to shut down after a fire at a substation less than two miles away caused a major power outage.

The blaze broke out at 8pm on Thursday and the airport announced its closure at 2am on Friday. 

More than 200,000 travel through the airport a day – with the chaos expected to have drawn out effects over the weekend. 

A Heathrow Airport spokesperson said: ‘Heathrow is experiencing a significant power outage across the airport due to a large fire at a nearby electrical substation.

‘Whilst fire crews are responding to the incident, we do not have clarity on when power may be reliably restored.

‘To maintain the safety of our passengers and colleagues, we have no choice but to close Heathrow until 23h59 on 21 March 2025.

‘We expect significant disruption over the coming days and passengers should not travel to the airport under any circumstances until the airport reopens.

‘We will provide an update when more information on the resumption of operations is available. We know this will be disappointing for passengers and we want to reassure that we are working as hard as possible to resolve the situation.’
