In addition to Nigel's comments - yes, Foreign Currency Direct give a good deal. We have just completed our property purchase - I registered with both Foreign Currency Direct and Moneycorp and found them both to be most helpful.  We also let them both know that we were registered with someone else and looking for the best deal - and in the end we got a lot better rate ( in the end with Moneycorp) by playing them off each other.
