What is the difference between a Commercial Electrician and a Domestic Electrical Installer?

Commercial Electricians and electrical installer’s work in offices, retail units, factories, commercial buildings and sites installing electrical systems for power outlets, lighting and wiring. They will have the knowledge of wiring to support large properties and systems compared to a Domestic Electrician who will have the experience of working in smaller residential properties.

What qualifications should an Electrician have?

A commercial Electrician will have an industry recognised level 3 qualification, for example, a level 3 diploma in electrotechnical services. Most people qualify as an electrician through an apprenticeship as they need both classroom training and work experience to gain the skills they need and it can take anything from two to four years to become fully qualified.

Anyone who carries out electrical work needs to be able to satisfy the requirements of the Health and Safety at Work etc Act 1974 and the Electricity at Work Regulations 1989.

What skills should an Electrician have in addition to their industry qualifications?

As well as their technical skills and qualifications, a Commercial Electrician should also have:

  • The ability to understand electrical plans, designs & blueprints
  • The ability to conduct a visual inspection and estimate the size of the job
  • Excellent attention to detail
  • Good communication skills
  • Excellent problem-solving skills
  • Be able to work as part of a team, working on large scale projects and builds with changing needs, plans and timescales
  • The ability to be able to deal with complex and demanding on and off-site situations

What should you do if you have a problem with your Commercial Electrics?

The electrics in your business or home should only be looked at by a qualified electrician as incorrect wiring and electrical systems can cause fire, damage to equipment and electric shocks. If an electrical system has surges or short circuits this can cause electrical fires, damage to the wiring which can cause problems and fires later down the line, as well as damaging electrical equipment connected to the same circuit. If you think you have an electrical problem or your electrics haven’t been checked and tested in your commercial property then you should contact an electrician quickly.

What are the signs or Electrical Problems?

  • Lights can dim or flicker
  • Warm or discoloured wall plates
  • A burning smell from switches or outlets
  • Circuit tripping
  • Fuses blowing regularly
  • Crackling, buzzing, humming or sizzling sounds
  • Any mild shock, spark or even a tingle from appliances, receptacles or switches
  • Tiny sparks when a plug is switched on

What should you look for in a Commercial Electrician?

You should look for a business or company that has been recommended by other businesses, has a good website which details their qualifications, insurance and other businesses that they work for, good customer reviews and have a friendly and professional response when you make contact with them.

How do you know which Commercial Electrician you should choose?

When you meet with an Electrician or business you can ask them a couple of questions and if they respond easily and without hesitation then this is a good sign. A good website with information about them as a business, along with a professional answering service and the offer to meet with you at your commercial business or property are all good signs. You will normally know if it is a business you want to work with when you meet them.

Questions to ask:

  • How long have they been in business?
  • How many people work within the business?
  • What electrical services do they offer?
  • What other services do they offer?
  • Do they offer electrical repair and maintenance contracts?
  • What electrical qualifications do they or their employees have?
  • What Health & Safety qualifications do they have?
  • What insurance and public liability insurance do they have?
  • What other businesses do they and have they worked for?
  • Why you should choose them?

What can cause an electrical fire?

Some of these can seem obvious, however, it’s a good list to check through:

  • Most electrical fires are caused by faulty electrical outlets and or old, outdated appliances and systems
  • Electrical appliances with worn or frayed cords can send heat onto combustible surfaces like floors, curtains, and rugs which can be the cause of fires starting
  • Running electrical cords under carpet and flooring can be the cause of electrical fires
  • Outdated wiring often causes electrical fires as it may not have the wiring capacity to handle the electrical systems within your commercial property
  • The overuse of extension cords can cause electrical fires and appliances should be plugged directly into a socket and not into an extension lead
  • Breakers should be triggered when circuits are overloaded by too much electricity, however, outdated breaker boxes often have worn connectors that don’t work as they should, causing electrical systems to overload which can cause electrical fires

If you have just moved into a Commercial Property then we would always advise that one of the first things you do is to get a suitably qualified Electrician to come in to assess and test your electrics.

What are the Legal Requirements for businesses in regards to their property electrics?

All business owners, their directors, managers and employees need to comply with “The Electricity at Work Regulations” which can be found at

What is The Electricity at Work Regulation?

In summary, The Electricity at Work Regulations 1989 is the statutory legislation in place that states that employers ensure the safety of electrical devices in the workplace, and those in control of all, or part of an electrical system are required to ensure that it is safe to use and is maintained in a safe condition. The regulation dictates that all portable equipment must be inspected and tested regularly to ensure that it is safe for use.

How often should you have your Commercial Electrics checked and tested?

It is recommended that if you have moved into a commercial building that you ensure the electrics are tested and safe immediately and that they are tested a minimum of every five years. If you are renting a commercial property then your landlord should be able to provide you with the documentation that states when it was last tested and checked. You can ask for this to be done prior to you moving into the building as part of your tenancy agreement.

What is an EICR?

An EICR (Electrical Installation Condition Report) is an inspection of the condition of an existing electrical installation in a domestic or commercial property and it tells you if there are any deficiencies against the national safety standard for electrical installations. During an EICR assessment, tests are also carried out on any wiring and associated fixed electrical equipment to check it is safe.

What is an EICR certificate?

An EICR is a formal document that is produced following an inspection of the electrics within a domestic or commercial property and it is carried out by a qualified and experienced electrician, approved contractor or business.

What does an EICR assessment include?

An EICR identifies any potential risks to health and safety that could be caused by incorrect and faulty electrics. The assessment and tests are completed by a qualified electrician to make sure your electrical installation is working safely and correctly and to the standards of the National Safety Standard identifying any electrical circuits or equipment that are unsafe to use

An EICR Report will list any electrical work that is needed and includes any electrical standards which have not been adhered to. It is vitally important that as a business owner or someone who is responsible for a business that you can demonstrate you have had an EICR report completed and taken action against any of the issues identified.

How often should you have an EICR done?

An EICR Report should be carried out every 5 years or at the point of installation to demonstrate the electrics in a commercial property are safe and in good working order. 

Who can issue an electrical safety certificate?

An EICR Report is completed and issued by a certified and qualified electrician and it demonstrates that all electrical circuits and appliances in a domestic or commercial property are in good and safe working order.

Is an EICR legally required?

The EICR legal requirements in England and Wales are not legally required, however, they demonstrate that you are adhering to The Electricity at Work Regulations 1989 which is the statutory legislation in place to regulate that employers ensure the safety of electrical devices and systems in the workplace.

What should you do if you are thinking about getting a Commercial Electrician?

We would recommend that you get recommendations from other local businesses to find a suitably electrician. Look at their website to see if it looks professional, details the services they offer and the businesses that they work and have worked with previously. Search the internet for reviews from their customers and always meet with them face to face at your property so you can get a feel for them as an individual or as a business. When you meet with them you can ask them:

  • How long have they been in business?
  • How many people work within the business?
  • What services do they offer?
  • What other services do they offer?
  • Do they offer electrical repair and maintenance contracts?
  • What electrical qualifications do they or their employees have?
  • What Health & Safety qualifications do they have?
  • What insurance and public liability insurance do they have?
  • What other businesses do they have and have they worked for?
  • Why should you choose them?

How do you maintain Commercial Electrics?

You maintain safe and legally working electrics by having them regularly tested and checked by a qualified electrician and this includes having an EICR assessment a minimum of every 5 years or when you first move into a commercial property or unit.

Why should you have your Commercial Electrics checked?

Faulty and old electric systems can cause fires and damage to your property and appliances so it is vital you have them assessed regularly. Fixed wiring testing accurately identifies electrical issues, their locations and any recommended actions needed.

My business is a 24-hour operation, how can I test my electrics without any impact?

Qualified and experienced electricians or an electrical contractor will have the expertise of working within the constraints of 24-hour operations and most of their testing will normally include live tests which can be scheduled around specific working and production processes, for example; shift changes, weekends, holidays, process changes, and cleaning or maintenance breaks. Your electrical system can normally be switched off in stages to ensure you are never without your whole electrics.

Will testing cause a lot of disruption and loss of power?

Some short power outages can be expected within your system, however, a lot of the testing can be done whilst the system is still live and an electrical installer can plan any work around your business operation.

Is electrical installation testing a legal requirement in commercial properties?

The law doesn’t require electrical testing to be carried out, however, it does state that you keep your entire electrical system safe at all times, therefore, regular assessment and testing is a must. A visual inspection or check is not enough to sign off the safety of your electrics. If a fire or accident happens as a result of an electrical issue then as the person responsible you need to be able to prove that you took every step you could have to have avoided the incident, and if not then it can be deemed as an offence. Test results, an EICR report along with maintenance and rectification records from a qualified electrician will provide this.

Is electrical testing a requirement for my business insurance?

A lot of insurers now are insisting that inspection and testing be carried out on a regular basis. If you suffer an avoidable accident and you are found guilty then by law you will have committed a criminal offence and insurers will not pay fines or compensation suffered as a result of a criminal offence.

Is electrical testing my landlord’s responsibility or mine?

It is usually dependent on the terms of your lease if you or your landlord are responsible for paying for electrical testing to be carried out. If you are going to rent a property then this is always something that should be agreed and included in the tenancy document beforehand. If you are on a full repairing lease then the cost will fall to you. Always remember that you are responsible to make sure that you and your staff comply with Health & Safety legislation and The Electricity at Work Regulations 1989.

How long does it take to install Commercial Electrics?

It will depend if it is a new building or if there are existing electrics in place and if they comply with current legislation, as well as the size of the property and the electrical system needed to meet the requirements of your commercial business and property. A visual inspection by a qualified electrician will normally give you an estimation of the amount of work involved.

How much does it cost to install Commercial Electrics?

As in the above answer, it will depend on so many factors but the end system must:

  • meet all latest compliance requirements & testing
  • have the most efficient electrical, security and networking systems to match your premises and budget
  • minimise energy waste

What is Electrical Maintenance & Testing

Electrical maintenance covers all aspects of testing, monitoring, fixing, and replacing elements of an electrical system.

Large scale commercial buildings and operations can have their own on-site and employed electricians who manage the day to day issues, however, large facilities will have complex electrical systems that specialised commercial contractors need to be utilised for when it is beyond the day to day electrical requirements. Smaller businesses and properties can often find it more financially beneficial to use local electricians for scheduled electrical maintenance and servicing. Professional Electrical Services will offer periodic inspection and testing services for either individual premises or multiple sites and estates.

What does a Commercial Electrician do in small to medium commercial properties?

A good and professional electrical installer or electrical contractor will carry out all electrical work from smaller jobs, such as visual checks, installation of electrical equipment, fitting lights and extra sockets and pat testing, to complete full or partial electrical wiring, rewires, new build installations, tenancy testing & reporting, emergency lighting, shop/office refurbishments, automation and security systems and 3-phase commercial / industrial rewiring.

What do Commercial Electricians do in Industrial or Commercial Properties?

An experienced and qualified commercial electrician will conduct a visual inspection design, complete electrical installation work, maintain and repair electrical tasks of all sizes and shapes, working alongside you and your business to ensure minimal impact to your operation at all times.
