Electrical rewiring can seem like a daunting prospect, especially when it comes to your commercial premises. However, it is not an area that should be overlooked as it’s essential for the safety of both your staff and your property. The financial burden would far exceed the costs of a rewire should a fire, injury or even death occur as a consequence of faulty or outdated electrics. It is also a great opportunity to improve the efficiency of your entire electrical setup and make considerable cost savings in the long run.


  • The first thing to consider is the age of the property. The general rule of thumb is any building over 25-30 years old, that has not had a recent electrical upgrade, is likely to need a full rewire. If you’re not sure about the age of the property or the quality of the wiring, it is best to hire a professional electrician to undertake an Electrical Installation Condition Report (EICR) to ascertain whether you need to take further action.

    If you have had major renovation work done or damage to the building such as flooding or fire then a full or partial rewire might need also be needed to ensure all wiring meets current regulations.

    Additional signs that you may need a rewire:

    • An old fuse board

    • Regularly blown fuses

    • Exposed cables

    • Faulty sockets and switches

    • Electric shocks from plugs

    • Sparks from sockets

    • A burning smell, burn marks or sockets which are hot to touch

    • Flickering lights

    • Buzzing or crackling noises

  • Firstly, one of our electricians will visit the premises and undertake a thorough inspection and discuss your needs. A rewire can be a good time to future proof your commercial property by installing smart lighting, additional sockets, updated smoke alarm systems, and CCTV. Following our initial visit, you will receive a fully comprehensive quote in which we will breakdown the costs for each item or aspect of the project. Once you have accepted the quote, we will schedule the works for a date and time that suits you.

    A rewire typically needs to be completed when the premises are empty. If you are having renovation work done, it is wise to schedule the first fix done before plastering. Our team will work with you to ensure any downtime to your business is minimised and you are back to work promptly. During a full rewire, our electricians will remove all the electrical wiring, cables, lights, sockets and switches in every room and replace with new units that comply with the latest regulations. In a commercial setting this may also include smoke detectors, alarm systems and CCTV.

  • Safety

    First and foremost, the primary incentive is improved safety in the workplace. Rewiring old and outdated cables significantly reduces the risk of electrical faults that could result in fires or electrical injury.

    Electrical Efficiency

    Properties built before the 1960s are typically powered by 60-amp systems, whilst this was adequate at the time, the demand of modern electrical equipment exceeds this. This low power can result in appliances tripping or burning out regularly and could pose a fire risk as well as damaging your electrical items. During a full rewire, you will be upgraded to a higher capacity system, ensuring your electrical appliances run safely and more efficiently.

    Property Value

    A full rewire will improve the resale value of your commercial property as well as being more attractive to potential buyers.

    Redesign/Upgrade Opportunities

    Are the sockets and switches inconveniently located for the needs of your business? Do you find you have insufficient sockets, particularly around desk areas? A full rewire provides the opportunity to redesign the electrical layout to suit your specific requirements and futureproof your premises for additional electric appliances. A rewire is also the perfect time to incorporate those all-important upgrades to improve your business including smart CCTV systems, LED lighting, smoke alarm systems and enhanced security lighting.
