Glad to see you in the Community, @stuartpriceuk.
Were you able to check if the following banks are showing up in the search results of your Banking screen? I'm unable to find the following accounts using my test account.
It seems that these banks aren't supported for open banking yet. You may attempt to tap the Request support for your bank option on the search screen.
In the meantime, you can manually add your bank transactions while requesting for support. You can check this guide for more details: Manually add transactions in QuickBooks Self-Employed.
Should you need anything else, please don't hesitate to leave a comment below. My door is always open to you. Thanks for dropping in and have a magnificent rest of your week.
