2. Scale of Work

The most crucial difference between a commercial and a domestic electrician is the number of projects or work they can take on.

Scale of Work

Domestic Electrician

Domestic electricians will typically work on small projects at home on their own. Sometimes they might be assisted by one or two less qualified people. They are not likely to take on industrial projects and will take longer than commercial electricians to complete any work.

Commercial Electrician

Commercial electricians can take on big industrial projects easily as they will have more people on the team who are both qualified and expert professionals in this field of work. They will also take a short time to do the equivalent job as they are more experienced.

3. Regulations

You should be careful about selecting the right electrician to save money during renovations or repairs. Every electrician is not knowledgeable about every regulation outside of their work area. Not following proper regulations and codes can have you fined.


Domestic Electrician

Most domestic electricians will be updated with the latest building regulations. This might not be the case for commercial electricians who primarily handle industrial projects.

Commercial Electrician

Commercial electricians will be updated with electric compliance rules, including PAT testing and EICR- Electrical Installation Condition Report.

They will be aware of legislative laws and will help you keep your business compliant. Their knowledge can also save you a good amount of money.

4. Knowledge of Equipment

Knowledge of Equipment

Domestic Electrician.

There are variations between industrial and domestic electrical work, which are pretty complex. Unfortunately, your regular electrician will not be familiar with the latter. Domestic electricians will know how to handle household electric work very well.

Domestic electricians are more familiar with household appliances. For example, they can help you install solar panels to save energy at your home.

Commercial Electrician.

Commercial electricians are familiar with installing, testing, and repairing any workplace-friendly system, for instance, an emergency lighting system. This system is a must for commercial places to help workers exit during emergencies like a fire breakout or an earthquake. Only commercial electricians will know how to properly and effectively install these types of systems.

5. Experience


Domestic Electrician

Domestic electricians are not experienced enough to work in commercial places and industries. They are better suited for home requirements and neighborhood jobs. For example, they can help you make your home energy efficient.

Commercial Electrician

Commercial electricians have experience in three-phase wiring, running wiring through conduits instead of walls, and using extra insulation for safety and protection. These skills might seem small, but they are significant for commercial electricians in solving electrical problems in industries and workplaces.


Commercial and domestic electricians each excel in their sector of work. It is better to consult a domestic electrician for household work and a commercial electrician for industrial jobs.

There are differences between the skills and experience of both domestic and commercial electricians. Knowing these will help you make better decisions about hiring one. Hopefully, this article has helped!


1. Can a commercial electrician do domestic work?

Ans: Commercial electricians have identical diplomas in electrical installation as domestic electricians, including further training. Since they have more qualifications, they should be capable of carrying out domestic work if needed.

2. What is the difference between residential and commercial wiring?

Ans: Commercial buildings usually have more wires than residential properties, and these come with added protection.
Domestic wires only require plastic sheathing, whereas commercial applications are contained in conduits or ceiling rafters. The wiring system also differs as commercial properties consume more electricity than households.

3. What do you need to know before hiring any electrician?

Ans: First, you need to know and specify what work needs to be done. If you just want to deploy your tube light or bulbs or just need to test the safety of your new electric appliances, then domestic electricians are what you need.
But if you want your wiring changed in any commercial buildings or need any heavy electric work done, then you will need commercial electricians.
Remember, commercial electricians can do many work and projects in different industries.
