As you can't do much with a UK PPL anymore its not really much use!
It is if you can't get an EASA medical: LAPL privileges on EASA aircraft until 2018 (and possibly beyond), validation in non-EU states (which you can't do with an LAPL) as well as full PPL privileges on Annex II aircraft including the ability to add night, FI, IR, MEP (which again you can't do with an LAPL).
