Insurance that covers behaviourist?

Can anyone reccomend an insurance which covers a behaviourists fees please? Ours is up for renewal on 1st Feb. we are with Healthy Pets which only covers a behaviourist for behaviour problems caused as a direct result of an insured incident -which would be medical.
Although I've managed to overcome Tilly's various behaviour issues as they occur it would be nice to know that I have the option to get professional help if things ever get out of hand.
