I take it back about the offer, i had to signup to Moneybookers to take up another bookies offer so i might as well do this one too now.
After speaking on live help the only 'fee free' options for UK residents are Neteller or Moneybookers. There is no fee for depositing but there will be a withdrawal fee if you request more than one withdrawal within 30 days of each other. The withdrawal request can only be requested on Mondays between 9:00 AM ET and 1:00 PM ET (2:00 PM till 6:00 PM GMT...i think
Info from their site:
