If you were interested in our item on international transfer fees and administration fees, you may wish to check out the CEV Transfer calculator at: http://www.cev.lu/Transfers-Area/AdminFeeCalculator.aspx
For Leagues in England and Wales, the current figure is zero, unless your team is taking part in a major international event, then it €850 (which could apply to a SW League teams if you happen to win the VE Cup Final and decided to take your campain into Europe).
