, I tried that a few years ago..via Lloyds Bank.. wanted to transfer money to FCD account with Kassikorn. Bangkok Bank (main clearing bank in thailand) wanted 50 or 60 pounds to clear it here in thailand. On top of the Kassikorn costs. Rejected it back to UK. Now I just issue a cheque, that clears in about 14 - 21 days and only costs about 20 pounds total.
Have not tried it since, but, things may have changed...
