What is a house rewire?

Old or faulty wiring can be dangerous, causing fires and injuries. In the UK alone, approximately 12,500 fires and 2,000 shock accidents are caused annually by faulty electrics.

House rewiring is a comprehensive task that involves removing and replacing old wiring and electrical components, often undertaken during home renovations when walls are exposed.

A complete rewiring of your existing wiring system is a great opportunity to relocate your lights, sockets and switches or even install new features such as outdoor lighting, kitchen appliances or a car charging point.

  • Fewer sockets than normal

Factors that affect rewiring costs

When you rewire your house, you may have to pay more than just the cost of new wiring and electrical parts.

Several key factors can affect the overall cost of a house rewiring:

Size of the property

When it comes to rewiring a property, larger homes require more materials, such as wiring, lights, sockets and power points. Additional labour is also needed.

The layout of a building

Multiple floors or non-standard designs will require more wiring and additional work.

Age or condition of your home

The age and condition of your property can affect the cost of rewiring. If your property is old and the quality of the existing wiring is poor, this can require more work and increase the price.

Likewise, if your wiring or consumer unit is difficult to access, the cost of rewiring will be higher due to the difficulty of the job.

Whether you are living in the house

Electricians can work faster and safer when your house is empty. It is best to schedule electrical work when the property is vacant.

New fittings and features

A full rewire is an excellent opportunity to relocate lights, sockets, and switches or add new features, like kitchen appliances and lighting. However, the time taken to complete the rewire will depend on the number of features you want to add.

Property location

Geographical location impacts rewiring costs due to the difference in labour fees and materials across the UK.

Waste disposal

Rewiring a house can result in a significant amount of waste, so disposal costs should be considered when budgeting for a rewiring project.

The rewiring process

The rewiring process involves various stages:

  • Planning lighting, switches, and outlets for each room
  • Removing old wiring
  • Installing new wiring
  • Adding external components such as switches and sockets
  • Installation of a new consumer unit
  • Plastering work
  • Safety certification

1. Set a budget and get quotes

Rewiring a house can be costly and cannot be done in stages, so hiring fully qualified electricians who can provide you with an accurate cost is crucial.

Get multiple quotes to ensure a fair price for your rewire. Be sure to include any new fittings and features you want to add, such as lights and plug sockets, so that the electrician can plan cable routes.

Upgrading things like light fittings are not particularly expensive, while more complex installations like electric car charging points and air source heat pumps can significantly increase costs.

Rewiring also gives you the opportunity to add smart home technology, such as CCTV cameras and automated systems.

Choosing a licensed electrician is crucial to ensure a home’s electrical system complies with safety standards and codes.

2. Existing wiring inspection

Before an electrician can rewire a house, they must review your existing electrical system for safety and compliance through visual examination and testing.

This involves checking for visible hazards like damaged wiring or loose connections and inspecting the fuse board.

Before starting a full rewire project, an Electrical Installation Condition Report (EICR) is carried out by an NICEIC-approved contractor to review the current wiring.

An EICR is designed to identify potential hazards and defects in electrics which could pose a safety risk to the property and its occupants, including fire hazards.

This report assists in determining if the wiring is safe and up-to-date, potentially avoiding the expense of a full rewiring.

3. Installation and upgrades

Our electricians will replace old wires with new ones, running them through hidden spaces like floorboards and attics.

New wires may need to be installed into your walls or floorboards if you’re installing new fittings. This can result in damage to plasterwork, which must be repaired to ensure no wires are visible. Carpets and floorboards will need to be lifted.

All these new wires are then connected to a safe new consumer unit (fuse box) that constantly checks for any problems with the electricity.

Once the rewiring work is completed, the electrician will install new electrical components such as sockets, light fittings, switches, and anything else specified.

4. Safety certification

After rewiring is complete, an electrical safety certificate must be provided to confirm compliance with building regulations.

How to save money on a house rewire

There are a few ways you can reduce the cost of an electrical rewire:

  • Be clear with the electrician about your budget so they understand what you can afford and ensure they can provide you with the best option.
  • Get multiple written quotes with a fixed pricing structure to avoid additional costs.
  • Prepare your home before the electricians arrive by moving furniture and lifting carpets.
  • Scheduling a rewiring job during other home renovations can help reduce your overall labour costs and minimise additional disruption.
