the letter
I moved overseas whilst working for BA a few years back - BA pay office were adamant that they would not/could not pay into anything other than an account held at a Bank with a UK sort code.We ended up keeping our UK Accounts and the banks were quite happy with a non-UK Address, so it can be done, but as spitoon has said be ready for all sorts of hurdles because of UK anti money laundering/anti terrorism/ anti fun regulations.
