Santander UK banking app and online services suffer major outage

On Friday, September 25, 2026, Santander UK experienced a major outage affecting its online banking, mobile app, and phone support. The problems started around 11:30 AM local time and impacted customers across the United Kingdom. Many were unable to log in or make transfers. Santander apologized and said it was working to restore services. The website service later came back online, but the app remained affected. This follows a similar outage at Lloyds Banking Group last month.
