It is the first question to ask the electrician. Are you licensed? If they give you a yes, then you go ahead and ask for confirmation of the same. Those who are not licensed or with fake licenses will hesitate to comply. The license can be a small document but it proves a strong point. For one to acquire a license, he/she has to have undergone the right training and is experienced in the field. It also shows the competence of an electrician to handle electrical jobs with safety guarantee.
