Why do I need a commercial electrician?

You may be wondering, what’s the difference between a commercial electrician and a normal electrician? Why can’t I use the cheaper option?

A commercial electrician is a highly trained individual who has completed additional training that allows them to work on commercial buildings. The main difference between a residential & commercial electrician is, commercial systems are much bigger and a lot more complex.


Qualifications/Professional training

1 of the 1st things you need to check before hiring a commercial electrician is their qualifications/training. There are 2 widely recognised awarding organisations in the UK. City & Guilds and EAL. To remain legal and above board, all electricians in the UK are required to hold a level 3 certification. To work on commercial buildings, they must possess an industry recognised level 3 NVQ. Furthermore, they must have a diploma in Electrotechnical services and a diploma in installing electrotechnical systems & equipment.



As well as qualifications and training. Experience should also be priority of yours. An electrician with more years of experience is likely to be more adaptable due to the exposure they’ve had in the industry. In summary, the experience can be the difference between a job well done and a job that will repeatedly require repairs.

Why can’t I use a residential electrician for commercial work?

As previously stated, commercial electricians further their knowledge which allows them to work on bigger systems. In addition, the biggest difference between the two is the regularity of the changes. Houses will often have the correct amount of electrical wiring for specific rooms. It is quite rare that they need additional electrical wiring. Occasionally this may happen when a room has been renovated.  For example, remodelling your kitchen.

On the other hand, in commercial buildings electrical wiring, data cabling, audio-visual and all other elements of technology are likely to change often. For instance, desk layouts, re-organised departments, office moves, and additional staff. All these changes require the electrical wiring to be altered. A commercial electrician will have an understanding on the buildings wiring and experience in planning for big commercial changes.


Public Liability Insurance

All businesses with employees are required to have Employers Liability by law. However, did you know, Public Liability Insurance is not compulsory if you’re self-employed?

An electrician without Public Liability insurance should be avoided at all costs. This should be a sign of their level of professionalism and care for their clients. By its very nature, electricity is dangerous. Majority of fires are caused by poor electrics or failed electrics. Public Liability insurance will cover your property if the fire was caused by the electrician.

Equally important, a commercial electrician must have the trade (commercial electrician) on their documents. The reason for this is because standard electrician policies do not cover 3 phase work, thus making the insurance invalid if not declared to the insurer.

Quality of work & Competency

Is your electrician’s work completed to British Standards BS 7671? Are they able to issue a BS7671 certificate for your records?

Before hiring anyone to work in your building you must do your research about the company you’re about to use. You should only entrust your electrical work to a company that is reputable. Additionally, check the reviews left by other customers. Does the company have a good informative website with case studies and information about their work? These are all signs of professionalism; it proves values their clients.
