Hi,
You have four choices:
EASA SEP
LAPL
NPPL SSEA
NPPL Microlight
There are threads and threads and threads about all the different options and attractions, many of them on the first page of Pprune in this section. Just look for NPPL and LAPL!
But simply: you have had six hours of lessons. Ask your instructor!
And if they can't explain how you can fly - or not - in 25 hours in a C42 and take 32 hours to do it as an NPPL and 40(-ish) as a LAPL and 45 as a SEP (except you won't be able to train it it for an EASA licence because it is an Annexe 2 aircraft) - then maybe you want someone else to tell you.
I'd be really interested to know what your instructor says: it seems, from the questions here, that there is hardly a single instructor in the UK who understands the air law about the licences they can - or cannot? - teach for!
