Just an update on my original post, I managed to transfer Sterling back via Garanti using their SWIFT online service, they charge 50TL or 65TL charges to do this 65TL is for same day transfer, I was transferring back to Lloyds Bank but for some reason it gets sent to Standard Charter London first who took £30 per transaction out before forwarding it to Lloyds who charged nothing. Bit miffed at the Standard Charter charges as it is Sterling being sent, I enquired at Lloyds who said they usually make a £7 per transaction charge but as it is sent from Standard Charter it is an internal UK transfer thus no charge from their side, and they don't know why it is coming via Standard Charter?
