Seriously though, have they clearly defined the steps needed to go from NPPL to this new fangled euro licence?
Also, I'd assume that the restriction on carrying passengers for the first xyz hours doesn't apply to taking along a suitably qualified pilot?
If you mean the conversion process from NPPL(A) with SSEA Class Rating to LAPL(A) with Single Engine Piston aeroplane endorsement, the answer is yes.
See CAP 804 Section 4 Part P Page 11-12.
