We charge the same hourly rate for dual training for both the LAPL and the PPL, in the same aircraft with the same instructor. I don't know of any instructors who are restricted to just the LAPL (though in theory that is possible) and I'm not sure what hourly rate we'd pay them. We've just upped the amount we pay instructors from £25 per hour to £30, the first increase in nearly 10 years. Locally, I know of one Club now paying £40 per hour. As far as I know, the requirements for the aircraft are identical for both licences. In any case, we've only got one aircraft so it's academic!
We do offer the LAPL in accordance with our DTO, using a commercially available syllabus, for those who want it. We started 2 LPALs last year, both of whom converted to PPL when the hours they'd attained exceeded the PPL requirement. As BillieBob says, the LAPL really only has a place for those who fall short of the Class 2, but can still get a LAPL medical.
