Three years ago, before we moved to Turkey, I tried to set up an arrangement with my existing bank (Natwest) to be able to transfer money to my Turkish account once we relocated. They insisted that to make an International transfer, I must go to the bank each time and complete the transfer form and present my passport, all to do with money laundering laws. To say the least, this might be difficult as I would then be living in Turkey! They insisted there was no way around this, without giving someone power of attorney in the UK.
I approached HSBC and opened an account with the express purpose of being able to transfer money to my Fethiye account once I was living here. I have had no problems at all and have made a few transfers. If you have a premier account with the branch transfers are free.
As far as cash is concerned, I believe that you are allowed to bring around 5000 GBP from the UK at any one time.
