When You Need Electrical Rewiring?

While renovating your home and adding new rooms, seeking an electrician’s rewiring expertise is essential. However, safety concerns also warrant a serious evaluation of your electrical system, potentially requiring partial or complete rewiring. Consider the following examples:

  • Regular fuse blowing.
  • Aluminium wires being not up to date anymore.
  • Outdated consumer boxes, switches, and sockets.
  • Wiring with obsolete insulation rather than modern PVC coating.
  • Colour changes around switches and sockets.
  • New appliances tripping continually.
  • Flickering lights needing frequent replacement.
  • Inadequate number of sockets in a room.
  • Encountering electrical shocks when touching or plugging an appliance.
  • Sparks emitting from electrical outlets.
  • Strange burning smells or buzzing noises.

In such cases, it’s crucial to prioritise the inspection and, if necessary, engage in rewiring to ensure the safety and efficiency of your electrical system. Our expert electricians are here to help you throughout the process.

What Are Types of Electrical Rewiring?

At Con-Fused, we offer two distinct methods of NICEIC-registered electrical rewiring in London.

Flush Wiring

Our skilled team removes the plaster to insert the cables directly into the walls. The walls are re-plastered once the wiring is complete, ensuring a seamless finish. This method provides a permanent and integrated solution, improving the look of your space.

Our certified electricians conduct thorough electrical tests to ensure compliance with the latest safety standards, guaranteeing your apartment or house is electrically secure.

Surface Installation

With this approach, our experts conceal the wires within plastic casings, known as trunking. The cables are discreetly hidden behind these enclosures, maintaining the goodness of your walls.

The surface installation offers flexibility and convenience, allowing for easier access to the wiring if any future modifications or maintenance is required.

Our dedicated electricians conduct comprehensive electrical tests after installing all the necessary equipment, ensuring optimal functionality and safety.

Our Process of Electrical Rewiring

Typically, a full house rewiring project takes 7-10 working days to complete. Many things are involved in the process, and our team will guide you through each step to ensure a smooth and successful rewiring of your property. Our electrical rewiring process includes:

Preparation Stage

  • Opening up ceilings or floors in relevant areas.
  • Taking precautions to protect carpets and floors.
  • Removing drywalls and creating a comprehensive wiring plan.

Wiring Installation

  • Removing old wires and electrical components.
  • Creating channels (chases) and drilling new holes to accommodate the cables.

Finishing Stage

  • Plastering walls to restore their original condition.
  • Restoring ceilings and floors to their previous state.
  • Constructing kitchen tops if necessary.
  • Carefully connecting the cables to sockets, switches, appliances, lights, and the consumer unit.

Inspection and Certification

  • Conducting a thorough inspection to ensure obedience to electrical safety benchmarks.
  • Certifying the electrical system as safe and fully functional.

How Much Does Electrical Rewiring Cost?

Typically, the electrical rewiring cost in London is approximately £2000 for a one-bedroom house and can range from £8000 to £10000 for a five-bedroom house; these prices can vary. The following are the factors that will influence the price.

  1. Size of the Property – Rewiring a flat is generally cheaper compared to a 2- or 3-bedroom house.
  2. Quantity of Electrical Points – More electrical points in each room increase the complexity and time required for wiring, potentially impacting costs.
  3. Type of Walls – Concrete walls require chasing, a time-consuming task that can increase expenses. On the other hand, plasterboard walls are easier to cut and demolish, generally leading to lower costs.


While it is possible to do the rewiring yourself if you have the right qualifications, it is important to note that rewiring work must adhere to building regulations.

If you are uncertain about your electrical competence, hiring a licenced and certified electrician is recommended to ensure the job is done to the required standard.

Homeowner’s insurance typically covers electrical wiring, but the extent of coverage may vary. If your home has older wiring, it is advisable to consider electrical rewiring to ensure adequate coverage.

It is generally inconvenient to stay at the house while the electricity is switched off for rewiring. It is best to find alternative temporary accommodation.

However, if staying elsewhere is not feasible, you can coordinate with the electricians to create a work schedule that minimises disruptions to your routine, especially if you work from home.

Old wiring itself does not directly affect your electrical bills. However, defective or incorrect wiring, damaged thermostats or appliances, and issues with underground wiring can indirectly impact your power usage.
