I didn't suggest that he would. But hopefully he will tell you what U value
you need to achieve, and where to find tables of material properties that
you will need when working out how to achieve it, and things like that.

No problem with that, but it's the owners who ask, "what size rafters
do I need?", "how much insulation do I need in the walls, roof and
floor?", "what's a damp-proof membrane?". I've some single storey

£500 on a set of plans, everyone else who puts plans in has to cover
the £500 of extra work it takes to sort out their mess.
