he's pleaded guilty - has he been sentenced yet? it may be that the court will order him to pay you compensation in any event. You may be able to claim from Criminal Injuries, although I believe this is limited to claims for personal injury plus incidental costs, and if there's no injury I don't think you can claim.
I'm sorry to hear this has happened, and hope that you do find compensation. I'm surprised that others have accused you of being part of the compensation culture - you have clearly been a victim and have suffered financial loss as a direct result of that. Good luck to you.
