All registered electricians are listed here. You should be able to find the electrician on that site and also it will tell you which CPS scheme he/she belongs to. You can direct any query/complaint to them.if she cannot get a certificate from this electrician, who should she complain to and what company would list the names of certified electricians?
PS Try and locate any agreement, quote, contract, etc that was given to the client by the electrician.
