Any Electrician, that can prove he is a qualified competent electrician should be able to be registered with his local council. Once registered there should be no fee whatsoever involved, or only the same fee that a scheme provider pays ...if they pay the council fee's at all!!
As far as i gather, if your registered with a council as an approved qualified electrician, then you don't need to be with scheme provider, and don't need a third party inspection, by the council, or a by a councils allocated electrical contractor on there behalf... Which is where these extortionate council fee's derive from!!
