PPL to NPPL - Medicals

[dwberry]

Hi All,
I've read that if one has a valid JAR medical, that can be used to satisfy the NPPL medical requirments (rather than finding a tame GP).

So if I converted from my PPL to the NPPL would that releive me of the need to ever have a medical again?

Would I need to get my doctor to sign something after my PPL/JAR medical expired?

Thanks in advance for any help.
