At the risk of repeating what others have already said, it does seem like an odd recommendation, and one wonders whether it is really being given with your best interests at heart, Gresgow.

In any case, I don't believe that a good debt adviser should even make strong recommendations in cases where there is more than one viable option available to a client. They should give information about each of the options, the pros and cons etc, and leave it to you to decide which suits you best. If you then choose to go down the trust deed route then fine, but at least you have chosen yourself with full knowledge of all of the options open to you.
