What you'll need
The mobile app. That's it!
Your step-by-step guide:
Login to the mobile app
On the app homepage you'll see an overview of your accounts including the overall amount and your 'available' balance
The 'available' number is the one should be most interested in as this is what you'll have once all your pending transactions have gone out
App available to customers with Online Banking and a UK or international mobile number in specific countries.
