What Is Involved With Rewiring A House?

The rewiring project does involve a good amount of work and knowing that to expect can make the process a lot less intimidating.

Your electrician will talk you through the work that will be completed and will be able to answer any of your questions.

Your rewiring will begin with a quote from an experienced electrician. You should always make sure that the person is qualified for the job. In order to be suitable, the electrician must be eligible to test and inspect wiring as well as being registered with a body such as NICEIC. This will give you the peace of mind that the contractor will complete and assess the work safely and within regulatory standards.

At this point, you will be able to discuss your needs with the electrician and find out exactly what the work will entail. You will also be given an estimate of the cost involved. It is important to keep in mind that rewiring a house is not a particularly cheap job, but it is always worth making the investment to keep you and your property safe.

While the cost of the project will vary from property to property, the below table shows the national averages for a full rewiring.


House Size

Average Cost

1 Bedroom


2 Bedrooms

£2500 – £3500

3 Bedrooms

£3000 – £4500

4 Bedrooms

£3700 – £5500

5 Bedrooms

£4500 – £6500


There are many different jobs that will need to be completed during the rewiring, and while every project will be different owing to the individual needs of the client, you can expect the following tasks to be completed.

  • New back boxes will be installed.
  • All wiring will be replaced.
  • Both lighting circuits and power circuits will be updated.
  • New fixtures and fitting will be installed, if required.
  • Fixtures and fittings can be relocated if required.
  • There is an option to install technology such as built-in speakers or lighting.

As a general rule, the rewiring portion of the job will be completed first and then any faceplates on the power sockets and switches will be added.

How Much Disruption Does It Cause?

One of the main reasons that people put off rewiring their house is that they believe it will cause too much upheaval. We won’t sugarcoat things, rewiring your house is a large job and may cause a level of disruption in the home.

In some cases, portions of the wall, floor or ceiling may need to be removed in order to access existing wiring and reinstall the new wires. For this reason, you may also need to factor in the cost and work time to have these replaced.

The most common problem is for houses with laminate flooring, in many cases, when the floors need to be removed, the entire room may need reflooring when the job is complete. For this reason, it may be a good idea to consider rewiring when you are renovating the home. While the system may not be quite ready for an upgrade, it is preferable to combine the two jobs to avoid having further disruption down the line.

Many people are also concerned that they will not be able to remain in their home while the work takes place. The good news is that there is no reason that you cannot stay at home while the electricians are working. However, you should consider that there will be a level of mess and dust, as well as the inconvenience of having people working in your home.

If you are able, it can be a good idea to stay somewhere else while the work takes place. Although, if you do choose to remain at home, your electricians will always endeavour to keep you as comfortable as safe as possible.
