I’ve allowed third parties (such as financial comparison websites, money management apps and payment services) access to my financial data. Will this be switched too?

No, you’ll need to cancel and re-authorise these with your new account details. You would need to contact the third party providers directly to arrange this with your new bank. If your old account is still open, your bank will be able to tell you which third parties you’ve given permission to make payments on your behalf, and/ or access your financial data. Not all Third Party Providers services are supported by all banks and building societies, so there’s a chance that the Third Party Providers on your old account may not be able to access your new account. Please check your new provider’s terms and conditions for more information about Third Party Providers.
