What is the price of Rewiring?

Looking to hire an electrician to rewire your property? Read our handy guide to find out how much your electrician will charge for rewiring your home.

What is Rewiring?

If a property is over 30 years old and still has its original wiring, it’s likely to need rewiring to meet modern standards. This is because wiring can become damaged or deteriorated over time. Modern standards have evolved to ensure safety, so most older properties won’t meet these new standards.

Even newer houses may require rewiring if the existing wiring is damaged or has been tampered with by a DIY-enthusiast. For this reason, it’s recommended that your wiring is inspected every 10 years by a registered electrician, to make sure everything is in order.

Rewiring a house typically involves upgrading the fuse box and replacing the wiring. You can also choose to have more sockets added to your home for your appliances, phone chargers, televisions and computers.

Your home may also need to be rewired if you’re planning a renovation project such as an extension or garage conversion. This is because your existing wiring will need to be able to safely carry the extra load.

Rewiring your home can be a major job and a large expense. However, due to the safety hazards of faulty wiring, it may be essential. Old or faulty wiring can cause fuses to blow, frequent power cuts or even electric shocks and house fires, so it’s important to book an inspection with an electrician if you suspect that your home may need rewiring.

How much does Rewiring cost?

Rewiring your home is a major project and can be costly. However, it’s often essential for both safety and convenience. It’s important to know how much rewiring your home is going to cost before you commit to hiring an electrician.

The price of rewiring your home is impacted by a number of factors, the most significant being the size of your property. Although there is no fixed rate, a breakdown of average costs of rewiring a home based on local UK professionals is given below.

What changes the price of Rewiring?

The price of rewiring will depend on several factors including:

  • Property size

  • Whether a full or partial rewire is required

  • Location

Property size

The biggest consideration when it comes to the price of rewiring your home will be the size of the property. The larger your house, the more wiring needs to be done and the more costly it will be. A four-bedroom detached home will have much more wiring to be done than a one-bedroom maisonette, so will therefore be more expensive to rewire.

Although there is no fixed rate for rewiring different sizes of property, a breakdown of average costs of rewiring a home based on local UK professionals is given below.

Average cost of Rewiring based on the property size
House size Average cost of rewiring
One-bedroom flat£1,800
Two-bedroom terraced£2,750
Three-bedroom semi-detached£3,750
Four-bedroom detached£4,600

Full or partial Rewiring

It goes without saying that a partial rewire will be cheaper than a full rewire. A full rewire can sometimes be avoided if the existing cabling is in good condition and able to carry any additional loads required.

A partial rewiring of your property in preparation for renovation work such as an extension or garage conversion can often be done by upgrading the fuse box to a modern consumer unit. 

The average price of upgrading your fuse box to a modern consumer unit can vary. However, a breakdown of average costs is given below.

There may be regional variances in the cost of hiring an electrician to rewire your property, depending on your location. The price will typically be slightly higher in the South, especially within London, and slightly lower in the North. However, the prices will still typically fall within the ranges above.

Is it worth getting Rewiring?

Damaged or deteriorated wiring can be dangerous. As well as causing power cuts and fuses to trip, poor wiring can also lead to electric shocks and house fires if not dealt with.

When you’re planning to undertake renovation work such as adding an extension to your property or converting the loft or garage, you may find that you need to rewire your home first. This is to create capacity for the additional circuits required for your new space.

If you’ve recently moved into an older property, you’ll need to check whether it has ever been rewired. Old wiring doesn’t typically stand up to today’s modern safety standards, so the chances are, your wiring will need to be upgraded.

If you’re unsure about whether your property may need to be rewired, it’s best to contact an electrician to carry out an inspection. They’ll be able to tell you whether there are any safety issues with your current wiring and whether it could be improved.
