Average cost to rewire a home

It’s important that you look after the wiring in your home because neglecting to maintain your electrics properly could lead to an electrical accident, like a shock or a fire. Damaged or old wiring is dangerous and should not be ignored. 

Rewiring is an opportunity to modernise the electrics in your home, especially if you live in an old house that hasn’t been renovated in years. Keep in mind that this will need to be done in line with current safety regulations. 

This guide covers the average costs of rewiring a house, as well as how long it will take and other considerations you should make before getting the job done. 

You could spend anywhere between £3,000 and £12,000 to have your entire home rewired, depending largely on how many rooms your property has. 

Expect to pay more for labour if you live in London and the Southeast, where costs can rise by up to 20%. The prices in this guide do not include VAT.

By rewiring your house, you will also be adding value to it, because modern electrical rewiring is often an essential for new homeowners looking to buy a property. Most of all, it will make sure you and your loved ones stay safe, avoiding electrical shocks or the potential outbreak of a fire. 

Because rewiring can sometimes get a bit messy, you might want to hire a post construction cleaning specialist to clean your home after your electricians finish the job.

Looking after your electrics is a vital part of homeowner maintenance. If you don’t, you could be at risk of suffering an electrical shock, or even a fire. Not to mention that new wiring will help prevent arc faults, overloads, and short circuits, all of which lead to power fluctuations that increase your energy bills. 

How much you end up spending on rewiring will depend largely on the size of your home, and where you live in the UK, as cost of labour rises in London and the South East. 

If any of the warning signs at the beginning of this guide seem familiar, you may be in need of rewiring. You can hire a skilled professional to rewire your home here.
