Heathrow’s bosses have addressed criticism of the airport’s response to a total power outage at the hub last month publishing a five-point action plan following a chastening appearance before parliament’s transport committee this week.

MPs on Wednesday (3 April) were told Heathrow had twice been warned about the resilience of its power supply in the days leading up to the wholesale power failure on Friday 21 March, which was caused by a fire at one of the substations supplying the airport.

The incident forced the cancellation of more than 1,300 services and impacted at least 300,000 travellers.
