Payments within the same country in the main currency of the country are considered as Local, including:
SEPA account holders sending EUR to SEPA counterparts including EEA territories
SEPA account holders sending GBP to UK counterparts including British territories
UK customers sending EUR to SEPA counterparts including EEA territories
Payments to other countries, or payments within the same country but not in that country's main currency are considered as International (see SWIFT transfers). For example: sending GBP from a Polish account to a Polish recipient.
