CATS is the place for the TK, because their "homework" is aligned with the QB so you don't have to study the voluminous (mostly garbage) study material to do the homework, and the homework is required to get signed off to sit the exams.
There are a number of FTOs around the UK that are fairly well organised and do the conversion course for a private pilot. Only a % of them will do a customer with his own plane though.
I know of an excellent instructor (Sussex) but the FTO which he works through for official training doesn't do customer aircraft.
