Hi @Martyn it’s actually a really tricky question to answer.
For example NatWest do support certain savings accounts and we have lots connected, but they sadly don’t enable all types of account. That’s the case with lots of the banks we connect with.
Basically the bank decides if they make an account available to connect via Open Banking and there is some complicated rules they use to determine if an account MUST be enabled or not under the regulations they have to follow. The accounts that must be enabled are referred to as ‘Payment Accounts’ - but normally things like ISAs etc do not get included under that definition. In fact I’m not aware of any cash ISAs that we get access to.
When it comes to Starling - they support access on every type of account. However, I think you probably are referring to a Starling ‘Space’ which is not an actual account but a virtual one. Sadly we can’t connect with certain virtual accounts like Starling Spaces or Monzo Pots (because they don’t have all the attributes of a normal account), but we’d love to in future.
So it does depend on the type of savings account you are opening.
