Do you do regular currency remittances? Having done this for many years with various remittance services, I find Transferwise by far the cheapest and one of the fastest services. Check it out. Your first 500GBP transferred costs you nothing. In addition, you can get paid in multiple currencies and hold it in the account which can also be spent with their Mastercard. Currency payments in foreign currencies using their Mastercard also fetches you the best exchange rate possible.
