My bank in Norway (SBanken, formerly Skandia Bank) allows me to specify a maximum amount that any creditor can ask for per month when using the equivalent of direct debits (and I also get notified in advance of every payment so that I can cancel either the individual payment or the whole agreement if I wish. This is all done via the web or app and takes effect immediately, no need to ask anyone at the bank to do anything. Here it is called AvtaleGiro.
