The Difference Between Domestic & Commercial Electricians

Jul 26, 2023

Electricians are trained professionals who specialize in the installation, repair, and maintenance of electrical systems. However, not all electricians are equal. There are two major categories of electricians: domestic and commercial. Although both types of electricians deal with electricity, their areas of expertise and job responsibilities are different. In this post, we’ll explore the differences between domestic and commercial electricians and the unique challenges they face.

So next time when you look for an electrician in Brighton, make sure that you check the certification and experience before hiring them. Check out the major points of difference before hiring.

Training and Certification:

The primary difference between domestic and commercial electricians is the level of training and certification required. Domestic electricians typically have a lower level of qualification than commercial electricians, as they specialize in domestic electrical work. To become a domestic electrician, you must complete a three-year apprenticeship and obtain a Level 3 Electrical Installation qualification. For commercial electricians, the training requirements are more demanding. They usually have to undergo a four or five-year apprenticeship and obtain a Level 3 Electrotechnical qualification. This qualification covers a broader range of topics such as electrical safety, wiring regulations, and industrial-level electrical installations.

Job Responsibilities:

Another significant difference between domestic and commercial electricians is their job responsibilities. Domestic electricians specialize in residential electrical work. This includes installing, maintaining and repairing electrical systems in homes, apartments, and other residential buildings. Domestic electricians work on a small scale, performing tasks such as replacing a blown fuse or fixing a faulty light switch. Commercial electricians, on the other hand, specialize in large-scale electrical installations in commercial buildings such as office blocks, hospitals, shopping centers, and factories. They are responsible for installing and maintaining complex electrical systems that require a high level of expertise.

Safety Standards:

Commercial electricians deal with higher voltage electrical systems, which pose a greater risk of electrocution, fire, and other safety hazards. As such, they must undergo a more rigorous training process to ensure they are familiar with safety standards and best practices for handling electrical equipment in commercial settings. They are also required to follow a more stringent set of regulations and codes when installing electrical systems in commercial buildings.

Equipment and Tools:

Commercial electricians use specialized equipment and tools that are not commonly found in residential settings. These tools include wire feeders, conduit benders, and knockout punches, among others. They also work with more complex electrical components such as switchboards, transformers, and industrial lighting systems. Domestic electricians, on the other hand, work with simpler tools such as wire strippers, pliers, and voltage detectors.

Work Schedule:

Commercial electricians typically work nine to five shifts, Monday through Friday, and may be required to work overtime or on weekends to meet deadlines. Domestic electricians, however, have more flexibility in their work schedules, and can adjust their hours according to the needs of their clients. Domestic electricians may also be called upon to work outside regular business hours, particularly in emergency situations such as power outages.


Overall, understanding the differences between domestic and commercial electricians can help you make informed decisions when you need electrical work done in your home or place of business. While domestic electricians are qualified to handle residential electrical work, it is important to hire a commercial electrician for large-scale projects to ensure the job is done right and in compliance with safety standards. Whichever type of electrician you need, make sure you choose a qualified and experienced professional to get the job done safely and efficiently.
