Scope of work

What these licenses authorize

Master Electrician

A Master Electrician license authorizes the holder to design, install, alter, and supervise all classes of electrical work in Texas, including the authority to qualify an Electrical Contractor business. The license is the highest individual electrical tier issued by TDLR. To qualify, an applicant must hold a Journeyman Electrician license, accumulate two years of journeyman experience, and pass the master exam. Annual renewal requires four hours of continuing education on the current National Electrical Code.

Electrical Contractor

An Electrical Contractor (TECL) license authorizes the business to bid, contract for, and perform electrical work in Texas. Every TECL must designate a qualifying Master Electrician whose individual license backs the contractor license, must carry general liability insurance, and is renewed annually. The TECL is the license a homeowner verifies when hiring a company; the named Master Electrician is the individual whose qualifications support the contractor's authority. Some Texas cities require additional local registration before pulling permits.
