When comparing commercial electrical projects to domestic jobs, it is worth considering that they definitely require a more advanced level of expertise. It is absolutely critical for commercial businesses to comply with safety regulations. There can be huge legal risks, insurance problems and expensive repairs if a poor contractor is hired. There are strict safety standards in Bristol, as with everywhere in the UK. It is extremely important to check the workmanship of the contractor you choose before employing them.

Explanation of a Commercial Electrician?

There are several differences between a commercial and a domestic electrician. In general, a commercial contractor will work on more complicated systems that are larger. For example, they would be responsible for industrial units, offices, warehouses and shops. A certain level of experience with high-load systems and very specialised equipment is a must. There can be many different factors involved, such as a full rewire or upgrade. Also, the installation of a distribution board with power systems and lighting might be necessary. To meet with regulations, there will need to be a fire alarm system that includes emergency lighting. Once this work has been carried out, there will need to be an inspection of the system with testing to provide the client with an EICR.

Check Qualifications and Certifications

It is recommended that a customer check the credentials of an electrician prior to any work being carried out to make sure that they are fully qualified with training and industry recognition (NICEIC, NAPIT). There are strict guidelines that need to be followed when rewiring and this will be very important for your insurance.

Verify Experience in Commercial Projects

Choosing an experienced tradesman will help to put your mind at rest and if they can show you previous commercial jobs that are similar, you will feel more comfortable. Business hours are something to consider as it might be necessary to carry out works when the office is empty. It is perfectly acceptable to ask for previous portfolios of completed projects to show you the quality of their work.

Check Insurance and Liability Cover

A few key factors to consider here, it is very important to check that any company you choose to use has public liability insurance to safeguard your business in the case of an incident. Asking for an EICR is essential for many insurance companies to prove the work done complies with regulations. There is such a thing as additional cover if there is a team involved which provides extra reassurance.

Understand Pricing and Get Detailed Quotes

Before you confirm a quote, ask for a transparent breakdown with details of what is included. Asking for several quotes is useful to allow for a comparison between companies. A clear timeline will mean the customer and contractor are on the same page and you both know roughly when work will start and finish. Some companies will offer a 24/7 emergency service which might be relevant to your business and worth considering. 

Conclusion

Electrical work requires qualifications. Finding someone who is reliable and with experience is important. Checking previous jobs, reviews and making sure that the person working has the necessary certification is advised. To ensure the work carried out is safe and finished to a high standard, this is a priority for businesses.
