Appendix A: Faster Payment Reversals Payment Reversals These transactions will only happen when there is a delay in the processing links between the receiving bank and the central infrastructure. If a receiving bank has not responded to the incoming payment within the agreed service level agreement, the central infrastructure will reverse the payment. Please see the diagram below for more information. To help you identify and reconcile these new types of transactions, we will provide these transactions to you with a new transaction code. Reversal transactions will be debits to your Agency Clearing sort code. When you are enabled to receive Faster Payments, you will also need to change your procedures to handle the new debit transactions in your Datalink file. The incidence of reversals should be very rare, and to reduce them further, NatWest will match reversal debits against the corresponding credit wherever possible without delaying your Datalink file. You should, however, make allowance for the possibility of reversal debits being reported in your file. Sending Bank 1. Payment out 2. Payment in Receiving Bank Central Infrastructure 3.
