There are very few changes you can make to a DDI. The layout has to stay the same as the template we have sent to you. This template has been issued by Bacs.
You can, however, use the 'Official Use Only' box however you wish to, or remove it completely.
If you have your own SUN your sponsoring bank will need to approve any changes.
If you have a Facilities Managed SUN then please send your amended DDI to firstname.lastname@example.org for approval.
