There are no Flyit machines in the UK that are approved for JAA use, so it's unlikely there are any at all.
There are two machines that are AATD approved (more than the Flyit has) and JAA approved as Flight Navigation Procedures Trainer (FNPT) Level II. They are at Police Aviation Services in Gloucester or Helicopter Services at Wycombe Air Park.
Give them a call to see what can be arranged.
