What is Electrical Installation Work?

What are the types of electrical installation work?

Electrical installations are crucial elements of any modern home or business. But they are also complex and, potentially, dangerous. And this is why it’s crucial that a professional always undertakes these works. You may be wondering how a professional electrical contractor is defined and it’s an excellent question. The answer is also surprisingly simple: they are defined by their certifications. These certifications and standards underline a contractor’s credentials and it’s important that you familiarise yourself with them.

What are the Different Types of Electrical Certification?

There are two main types of electrical certification:

  • Electrical Installation Certificate (EIC):

    This form of certification declares that a specific electrical installation is safe to use. This declaration starts from the date and time stated on the certificate. Typically, an EIC will be generated whenever any major electrical installations take place. Examples of where an EIC is required include fitting new lights, circuits and also specialist installations such as in bathrooms.


  • Minor Electrical Installation Works Certificate (MEIWC):

    Whilst major electrical installations will always require an EIC, less intrusive and minor electrical works will only require an MEIWC. This form of certification will be issued when alterations and additions are made to existing circuits and cover non-specialist locations as opposed to bathrooms and kitchens. Much like an EIC, an MEIWC confirms that an electrical installation is safe to use and conforms to all existing regulations.

It’s crucial, as a property owner, that you obtain these certifications whenever any electrical installation work takes place on your property. Without the correct certificate you are walking a dangerous tightrope of operating with unregulated electrical installations. As well as the safety risks there is also the risk of receiving hefty fines from the authorities.

Working With the Right Contractor

If you want your electrical installations to be maintained correctly then you want to team up with a professional. And it needs to be one who understands the BS 7671 electrical installation requirements. This branch of regulations specifies that all wiring systems within a building need to be classified as safe. Important aspects of the BS 7671 include protecting wiring systems from thermal effects, electric shocks and any voltage disturbances. But how exactly do you find electrical contractors whose professionalism can put your mind at rest?

Although it is not a legal requirement, the National Inspection Council for Electrical Installation Contracting (NICEIC) acts as a seal of quality for any approved members. Backed with government approval, NICEIC regulates electrical training for contractors and ensures that certain standards are met and maintained e.g. conforming to the current edition of the BS 7671. Contractors who are registered with NICEIC regularly have spot checks on their work and are required to have a public liability insurance with a minimum value of £2 million.

Final Thoughts

Everyone wants their electrical installations to work correctly and with the minimum risk of danger. This can be a tough ask due to the many complexities and technicalities involved in electrical installations. But working with an electrical contractor who is well versed in the legal requirements of certification makes this easier. And, to guarantee levels of excellence and care, always work with a contractor who is registered with NICEIC.

Electrical Installation in Construction

Electrical work in the construction field

Electrical systems are a crucial element of any construction site. Modern power tools and machinery are essential when it comes to construction works, so you need to be backed by strong electrical systems. These tools will allow you to complete works quickly and avoid the penalty payments associated with late completions. But where there are electrical systems there is complexity. And there are numerous hazards that come hand in hand with electrical installations. Understanding the setup and components of these systems, therefore, is essential.

Electrical installations on construction sites

Construction sites are hives of activity with all manner of machinery helping to provide a variety of different workforces. Accordingly, there will be a complex network of electrical installations, some interlinked and some standalone. The most common systems you might require are:

  • Temporary Power Supply: Not every construction site will have immediate access to an electricity supply. This could be down to the site being situated in a rural location or down to local geography. Either way, the only way to bring electricity to your site will be through a temporary power supply. These temporary installations are typically provided by local utility companies and provide your site with a constant electricity supply.


  • Fixed Wiring: Probably the most important electrical system to be found on a building site, fixed wiring helps support almost all electrical activity on site. Anything that is involved in distributing electrical power from A to B will be part of a fixed wiring system. Distribution boards, power cables and sockets are all part of fixed wiring. It’s a system which ensures that your workforce is able to power its tools and complete their work effectively.


  • Circuit Breakers: A crucial part of any construction site should always be safety. And, when it comes to working with electricity, safety is paramount. The biggest risk associated with electrical systems is electric shock, so your workforce needs to be protected. Thankfully, circuit breakers are systems which minimise the risk of electric shock. When an excess (and dangerous) current is detected, a circuit breaker automatically cuts the current flow. This protects the circuit and anyone working on it.


  • Generators: Even a construction site with a comprehensive power supply is going to need a helping hand here and there. But help is at hand in the form of portable generators. A common sight on construction sites, portable generators are powered by either fuel or batteries. These additions to your site allow you to operate tools and machinery at all times and in all locations


  • Electrical Switchboards: An essential part of any electrical system, an electrical switchboard helps to direct electricity on a construction site. The switchboard is a central hub which is used to direct electricity stemming from one main source to smaller areas of electrical activity. Switchboards themselves are divided into several different sections which one main power section and the rest dedicated to distribution.
