Guidance to consumers impacted by Heathrow Airport incident– 21 March 2025

Heathrow Airport is closed today due to a fire at a nearby electrical substation, affecting the supply of power to its terminals. Unfortunately, this means that today’s flights to and from the airport have been cancelled. The knock-on effect may also lead to delays and further cancellations over the weekend.
