More than 1,300 flights to and from Heathrow Airport will be disrupted on Friday due to the closure of the airport as fire crews continued to extinguish a fire at a nearby electrical substation.

Some 100,000 homes were left without power, more than 100 people evacuated and thousands of travellers plans thrown into chaos after a transformer within the North Hyde electrical substation caught fire in west London.

The airport, which is supplied by the substation, said it was among those impacted by the power outage.

Online flight tracking service FlightRadar24 said the closure would affect at least 1,351 flights to and from Heathrow.

It said 120 flights to the airport were in the air when the closure was announced. The cause of the fire is not yet known, though chairwoman of the Commons Transport committee Ruth Cadbury said it was 'speculative' to suggest the blaze had been caused intentionally'.

Heathrow is the UK’s largest airport, with more than 83.9 million passengers travelling through its terminals in 2024.
