TransferWise gives you the real exchange rate, also known as the mid-market rate(which you can find at xe, google or yahoo finance) to convert your money.
I tried their system on my friends recommendation for the first time and got money transferred within a day.
Bonus:
Treat your friends with a free transfer up to £2,000. For every three friends who use their transfer we give you £100 as thanks for your help.
