SEPA INST is a payments network in the EEA and some other countries (e.g. UK), and it is the future of SEPA SCT (regular SEPA payments). You can find a list of SEPA INST participating countries here:
The main differences between SEPA Instant and regular SEPA payments are:
- Regular SEPA payments have 4 execution times during the day when payments are processed. SEPA Instant payments do not have cut off times and can be executed at any time
- Regular SEPA payments are processed from 8:00 - 18:00; after these hours payments are not processed. Regular payments are not processed during weekends and public holidays, while SEPA Instant payments are processed continuously without interruptions.
