You can be an instructor with an NPPL and medical, although the ANO doesn't allow it. No CPL is required, nor is a JAR of any sort. You will just get a letter from the CAA saying that they won't prosecute you for aerial work in a microlight.
This is because of crap drafting of the NPPL and a lack of realisation that every new microlight pilot has no option but to do NPPL. The latest revision of the ANO (out a couple of weeks ago) has not corrected this gaping legal hole.
Best to call the CAA and speak to them direct.
Apparently they will write to you to say that they won't prosecute you. How this would hold up in the event of an accident is open to debate. In most criminal cases, it is the CPS that prosecute people and they may want to consider the matter further.
The sooner people at Gatwick sort this diabolical situation out, the better.
Oh... you need 100 hours too.
