How much does it cost to rewire a house?

Want to know how much it costs to rewire your home? We’ve created a detailed guide, discussing everything you need to know about improving the electrics in your property. Please note, all prices are accurate as of 2024.


If your wiring is faulty or outdated, rewiring your home can be essential in ensuring the safety of your property. Rewiring your house is often necessary if you’ve moved into an older property, or if you’re looking to upgrade your home to be more electrically efficient. Whether its a small flat that needs rewiring, or a multiple bedroom house, understanding the costs allows you to plan and budget accordingly.

For the most accurate quotes, be sure to be specific about the size and scale of your property, and the current state of the electrics in your home. Below, we outline several factors that can affect the price of rewiring your home. 


Average costs of rewiring your home

Rewiring your home is vital to ensuring safety and preventing potential risks, such as fires or failures in your electrical systems. In your property, some rooms, such as kitchens, will require more extensive rewiring than others. The cost of rewiring will also be based on the size and scale of your property. 

The average cost to rewire a house in the UK is £5,000. Below, we’ve outlined the average costs of rewiring your property, depending on its size. These prices are all based on averages, so if you want a more in-depth understanding of what is included in the costs of rewiring your home, be sure to read on. 


Size of your propertyAverage cost
One-bed flat£3,900
Two-bed flat£4,800
Three-bed flat£5,650
One-bed house£4,200
Two-bed house£4,800
Three-bed house £6,255
Four-bed house£7,730
Five-bed house£10,000


Factors impacting the cost of rewiring a house

The cost of rewiring your property can vary based on several factors. These include:

  • The size and scale of your property
  • The quality of fixtures and fittings
  • The number of electrical sockets
  • The complexity of the existing wiring system
  • Whether your home is occupied (it’s easier for electricians to work in unfurnished, empty properties)
  • Where you live
  • The age of the property (particularly if it is under conservation)

If your property is larger, older and already occupied, then you’ll be paying significantly more than a newer, smaller flat. Equally, if your property is older, you will likely need to fit extra sockets, which will cost more, but will also increase the utility of your home. If your home has faulty light fittings, or you want to install light features, this could also increase prices. 

When hiring an electrician, be sure to be specific about your property and your requirements. This will allow you to get the most accurate quotes possible when discussing your options. Through MyBuilder, you can discuss your project with several local, qualified electricians, review their job histories and compare quotes, all in one place. 

What does the cost of rewiring your home include?

When it comes to rewiring your property, the process will usually involve two stages. Firstly, all derelict and faulty wiring will be stripped from the property. Next, new switches, sockets and fittings will be installed, and the system is then connected up to the power grid. Your electrician will also thoroughly test the system to ensure that there are no loose connections, and that your electrics can run safely. 

Usually, the quote you’re given for rewiring your home will include:

  • Removal of old wiring 
  • New wiring throughout your home
  • Installing new sockets and switches 
  • Installing a new fuse box (also known as a consumer unit)
  • Minor plastering work to fill small holes
  • Circuit testing
  • Installation certificate to prove all work meets current building regulations  

It’s important to note that the price you’re quoted for rewiring won’t include major plastering work, carpet fitting or any decorating needed. These will need separate quotes, potentially from other tradespeople. 

When hiring an electrician, you should ensure that they are able to provide an installation certificate to prove all work meets current Building Regulations legislation. Without this, you cannot guarantee the safety of the electrics in your home and may need to pay for an electrical inspection.

Cost of electrical inspection


In the UK, Building Regulations ensure that your property, regardless of whether you are renting or own your home, is safe and compliant with good building practices. 

When it comes to the electrics in your property, Building Regulations legislation requires that your electrics are tested every ten years if you own your home. If you are a landlord, or are renting the property, these tests should take place every five years. 

A qualified electrician can carry out an Electronic Installation Condition Report (EICR). This will highlight issues such as poor wiring, faulty connections and protection against short circuiting. An EICR will also include:

  • Inspection of the fuse box (consumer unit)
  • Checking the polarity of the installation
  • Inspection of switches, sockets and other fixtures
  • Testing protective devices that aim to prevent short circuiting or overheating

If your home is over 25 years old, and hasn’t been rewired, it will likely need to have an electrical inspection. Signs that your wiring may need replacing include:

  • If cabling is covered in fabric or rubber rather than uPVC
  • If the fuse box (consumer unit) has large ceramic switches

If you need to get an electrical inspection done for your property, the price will depend on the size of your property. Here’s a look at the average expected costs:


Size of your propertyAverage cost
One-bed flat£150
Two-bed flat£175
Three-bed flat£200
One to two-bed house£175
Three to four-bed house£225
Five or more-bed house£375

Labour costs of rewiring your house 


The main expense of rewiring your home will be from the cost of labour. While an electrician can do the majority of the work, you may also need to hire a carpet fitter, or a plasterer to cover over any surfaces that could be damaged during electrical works. 

Here are some of the average day rates you can expect to pay:


TradespersonAverage cost (per day)
Electrician £320
Carpet fitter£240
Plasterer £175


Additional costs to rewire a house 


If you’re hiring an electrician to rewire your home, there are several other tasks that an electrician can do to improve the utility of your space. 

If you fancy some ambient lighting for your space, you can hire an electrician to replace a light fitting. This usually costs £65 per light fitting. 

If you’re security conscious, an electrician can install a security light with a motion sensor. This will usually cost around £125. If you’re looking to install a full-scale CCTV system, this will cost around £1,375.

Some other costs to consider when having your house rewired is furniture removal and storage. Having your electrics rewired can be an invasive and messy job, meaning that the majority of your furniture will have to be removed and stored somewhere else. If you don’t have the space to store your furniture, or need help with removals, you can hire a storage unit or pay a removals company to help. 

A full rewiring of your home may require you to move out into temporary accommodation. This could mean you have to pay to stay elsewhere, incurring extra costs. 



How long does rewiring a house take?

With an extensive project like rewiring a house, it’s worth keeping in mind the expected time scale of the work, so that you can plan to temporarily move out of your home and remove furniture in plenty of time. Below, we’ve provided an average length of time for rewiring a property.

How to reduce rewiring costs

Rewiring your property is essential to ensure the safety of your home. But costs can be high, especially if you have an older house that’s also fairly large. Here are a few ways to save when rewiring your home:

Hire a registered electrician 

When hiring an electrician, you should be sure to ask if they are a part of the Competent Tradesperson Scheme. This ensures that tradespeople are up to date on the latest Building Regulations laws in your area and means that any work they complete will be done accordingly. This will help save you money overall, as it means you can avoid paying extra for an electrical inspection. 

Understand when rewiring is needed

Before considering a full rewiring of your property, be sure to check whether it’s necessary. A few signs your property needs rewiring include:

  • If your property hasn’t been renovated in 20 or 30 years
  • If your property has round switches
  • If your cables are made of rubber or fabric
  • If any sockets are fixed to skirting boards

If your property includes any of these, a complete rewiring will be necessary to prevent electrical fires, and to ensure the efficiency of the electrics in your property. 

Plan before any work starts 

Rewiring your home can be an extensive and messy process, which will require plenty of planning. Before any work begins, you’ll need to consider options for temporary accommodation, as it might be necessary to move out of your property while the work is completed. By planning ahead, you can save money by booking temporary accommodation well in advance, or arrange a stay with friends or relatives while the work is done. 

Equally, rewiring allows you to redesign your home’s electrical systems to suit your needs. By planning ahead, you can save money by avoiding the need to rejig or change the placements of sockets and wires after the job is completed. 



Does my house need rewiring?

If you’re unsure of whether your house needs to be rewired, the best way to find out is to hire an electrician to carry out an EICR. This will give you the opportunity to thoroughly test and investigate any issues that might be occurring with your electrical systems, before committing to rewiring the whole of your property. 

There are a few issues that could indicate problems with your wiring. These include:

  • Your fuse box tripping regularly
  • Any electrical wires covered in rubber or fabric
  • Flickering lights
  • Any discoloration on electrical fittings
  • Fuses or bulbs that keep blowing regularly 

If you see any of these problems, it’s worth contacting a qualified electrician to investigate your electrical systems. 

Can I rewire my house myself?


Rewiring a house is an extensive process, which requires experience and technical knowledge. Rewiring a house without proper expertise will result in faulty wiring and will cost more money if you need to pay for any corrections. If you aren’t a professionally trained electrician, it is not recommended to rewire your own home, as it is potentially dangerous.

Does electrical rewiring have to comply with Building Regulations?


So long as the wiring in your home is safe and working, it is not necessary to rewire your property before selling. However, if your property’s sockets and switches are looking old, then rewiring can add value, and your property will be more appealing to buyers who might be put off by faulty or outdated wiring. 

Your house rewiring checklist

  • Plan beforehand

Rewiring a property can be a very extensive process and will require furniture to be removed and stored elsewhere. You may also need to vacate your property while the work is being done and will need to arrange temporary accommodation. Before you hire an electrician to rewire your home, be sure to plan ahead and make necessary arrangements before work begins. 

  • Calculate your budget

Rewiring your home, especially if you live in an older and sizeable property, can be expensive. Be sure to calculate your budget properly so that you’re not caught out by any costs. Your electrician should be able to help you by providing a detailed quote.

  • Choose a registered, competent electrician with relevant experience, qualifications and accreditations

By hiring a qualified electrician with relevant experience, you can ensure the electrical systems installed in your home are safe and effective. It’s also worth checking an electrician’s credentials to make sure they are registered with the Competent Tradesperson Scheme. That way, you can ensure that all your work is completed in line with Building Regulations.
