Nothing wrong with PAT, good instructors, friendly, helpful, priced pretty much the same as the others.
However a note of caution - you will pass your IR first time, which sounds great but it means that even if you think your ready, you will do another, 5, 10, 15 hours, until they are absolutely convinced you'll pass. This means don't count on passing in minimum time and financially this can really hurt when every hr costs many hundreds of pounds.
I thought it was just me but speaking to others afterwards they all felt the same.
