Trouble logging on

If you’re waiting for log on details to come in the post, please make sure you’ve waited at least 6 working days for these to arrive.

If it’s been longer than 6 working days, or you need further support please contact us.

If you’re registered for OTP (One Time Passcode), you can activate your log on details in the Mobile Banking app or through Online Banking

What if I’m not registered for OTP?

If you’re not registered for OTP, you’ll need to log on for the first time using Online Banking. This is to confirm your contact details. Once you’ve done this, you can use the Mobile Banking app.

If you need further support please contact us.

If you're locked out of your account, you've forgotten your details or can't log on to Online Banking, it's easy to reset your details.

You’ll need:

• Your Personal ID
• Your registered mobile phone

If you’ve forgotten your Personal ID, you can find this by visiting our Forgotten your Personal ID page

You’ll need:

• Your valid debit or credit card,
  Or
• Your account number and sort code, which you can find on your statements.

We recommend you don’t use saved, bookmarked or links in your favourites to access your Online Banking. If you’re using a password manager to fill in your log on details, you could try typing these in instead.

Email verification

We use email verification as a way of checking it’s you in the Mobile Banking app.

• Check that we hold the correct e-mail address. We’ll confirm this with you in the app. If you need to change your e-mail, take a look at our changing your details page
• These can take a few minutes to come through, and only the most recently sent link will work. If an email address is linked to business or education accounts, it may be blocked by the receiving organisation.
• To make it easier for you to know it’s the right email, the email will have a unique reference. This is valid for up to 15 minutes. If you’ve received multiple emails, use the link that has a reference matching what you see in the Mobile Banking app.
• You need to go into the email on the device you’re using the app on. You can either use your mail app, or use a web browser on your device.
• You may need to refresh your email inbox. This can usually be done by swiping down whilst in your mail folder. 
• Sometimes the email can go into spam, junk or promotions folders in your inbox so check these if you didn’t see it in in your main inbox. You’ll also need to have space in your inbox to receive emails.
• You’ll need an internet connection to use the link.
• When you go to your email to get the link, make sure you don’t force close the app.
• You can restart your device if you see an error message when you press the magic link button.
• If you’re an Android user, you might need to turn on links in your device. If you go to settings on your device and find your App Management settings, you can tap the ‘Santander UK’  app and tap ‘set as default.’ You can toggle on ‘open supported links’ and ‘supported web addresses’ to allow the Santander UK app to use those links.
