Hi @Robert-Purple-Lynx-1913986431#36339 π
To initiate the Switch Service you go to your profile picture and then Dutch Switch Service (overstapservice).
In my opinion, I don't like the service at all. There are some serious drawbacks reading the Terms & Agreements. Especially the cancellation fee, I understand there are costs involved for the bank cancelling the service but the amount totally scared me off.
With certain banks it is not possible to cancel the old account (or it is a lot of hassle) and you'll need to keep paying for the old account for 13 months, while the service lasts, and again remember the costs for cancelling. Besides that, I have about 20 monthly Direct Debits, 19 of them could be changed within like 2 minutes of work (per company). Signing in on their site -> profile settings -> change account number. So thats not even an hour of manual labor but you are sure everything is done well. You get the idea. Some mandates can't be switched just by using the switch service and need manual changes anyway. And to reply to your number 2). It is indeed not possible (yet) to use it with bunq for joint accounts.
Have a nice day! ππ
