A power surge on Sunday, October 25, 2026, at London Stansted Airport caused delays for approximately 250 flights and resulted in six cancellations, disrupting airport operations.
Security screening and baggage handling systems were knocked offline by the electrical fault, causing long queues and congestion inside the terminal. Passengers experienced extended wait times as airport staff worked to restore services.
Prior Transport Disruptions from Storm Boelo
The disruption came during a period of severe weather in the UK linked to Storm Boelo, which brought strong winds and heavy rain. Nearby railway infrastructure suffered from fallen trees damaging overhead electrical cables near Stansted Mountfitchet, leading to cancellations of
Stansted Express services on Friday and Saturday before the airport incident.
Despite the railway issues, the airport clarified the Sunday power surge was a separate event from previous rail disruptions.
Restoration of Systems and Official Response
Stansted Airport confirmed all affected systems were restored by Sunday evening. The airport issued an apology to passengers and stated teams remained engaged in assisting travelers and supporting airline operations as normal service resumed.
Passenger Guidance Following Disruption
Travellers on Monday, October 26, 2026, are advised to verify their flight status individually due to residual effects on scheduling. Passengers whose flights were cancelled on Sunday may qualify for compensation or alternative transport in line
with UK passenger rights. Airlines are required to provide appropriate assistance under these regulations.
Passengers should keep any valid receipts for extra expenses and contact their airline for information on disrupted bookings.
