Most of the main banks in the UK offer services online and via their applications, so you can easily open and run your bank accounts remotely. There are also banks that are digital-only or mobile-only.
You can open your digital account remotely, but you will need to supply your email address, phone number, and ID document.
Most digital banks such as Revolut, Monzo, Starling or Curve offer 24/7 in-app support, which is a huge customer improvement above the call-center support provided by most traditional banks. In fact, British users cite convenience, better terms of service, and the ability to track spending in real-time as the main reasons why they prefer to use online banks. When choosing one for your business, do check websites such as TrustPilot to see what the existing users are saying and what are the pain points of these banking apps.
