Heathrow Airport said it is “open and fully operational” on Saturday after the airport was shut over a loss of power caused by a substation fire.

Flights resumed at the west London airport on Friday evening and restrictions on overnight flights were temporarily lifted following hours of closure, after a blaze knocked out an electricity substation in Hayes late on Thursday evening.
