You want to transfer money from the UK bank account to a Thai who has a bank account in Thailand?
correct?
If so, you will need the following
- full name of recipient in English
- name of bank
- bank account number
- swift code of the bank
then ask your bank how to transfer money via SWIFT
or as said above use WISE.COM but you need to create an account
or last but very expensive option is WESTERN UNION, recipient can pick it up almost instantaneously
