I was very skeptical when they said they would need my banking details to login so they might want to re-word that bit, but otherwise, the whole process was nice and easy - just take a picture of your passport, confirm some details, login to your online banking and allow them read access to your current account and you're done. The only thing I do wonder about is that they do now have read access to my current account - is it up to me to withdraw that access now? There is no follow up except for a review request. I also don't know if I passed all the credit checks etc as that information is provided to the letting agency not the tenant, so although the process is easy and simple you are still left wondering.
