4. Do you offer 100% customer satisfaction?
Licensed and insured contractors are likely to offer you 100% customer satisfaction.

A non-licensed one doesn’t.

A non-licensed electrician may do more harm than good and you can’t possibly file a claim against them.

5. Do you have a business license?
In addition to holding a professional license, inquire if the electricians hold a valid license to operate a business in their area.

Also, ensure the license is current and updated.
