Wiring a van.

Hello!
I am about to start wiring process of my catering van as well as piping work for lpg appliances.
Could you please explain to me what kind of qualification are required for such jobs ? I want to check first if I can use help of my friends who work with electrical installations.
I am working on a very low budget but I do consider using mobile catering manufacturer, however it would be helpful to know what qualifications would meet legal requirements when getting all necessary permits.

Thank you!
Mike
