Maybe you can use some German bank. They allow one to interact with their API for free. I use GNU cash for it. Though I doubt that you can file your taxes via GNU cash and be aligned with current UK law. You would need to check it for your own.

Gives you an adapter and an standalone tool. All banks should use the same API, apparently.
