How much does a house rewire cost?

By Katie Anderson on May 8th, 2014

Do you live in an old property with aging electrics? Perhaps you’ve brought an old house that needs rewiring? The older your home the more likely it is that the existing wiring won’t meet current electrical safety standards. 

Electrician If your house is 25 years or older, and the electrics haven’t been upgraded in that time, it means the existing wiring won’t meet the Part P Building Regulations Electrical Safety Rule.

Should that be the case, then it’s time to call upon the services of a local, recommended electrician. Rewiring a house isn’t a job for a DIY enthusiast and must be carried out by a skilled experienced electrician.

Of course, you’re bound to be wondering how much it’s going to cost? Rewiring a house is a big job so it won’t be cheap.

Cost to rewire a house

How much it’s going to cost you will depend on the type and size of your property, and how many rooms require rewiring. Which? Local carried out a survey of electricians to determine the costs involved*:

An average 2 bed terraced – £2,200 up to £3,000
An average 3 bed semi – £2,800 to £4,000
An average 4 bed detached – £3,400 up to £5,000

What does rewiring a house involve?

All of the old wires and fittings will be removed and replaced with brand new wiring and fittings. It’s quite a big job and, depending on the type of property being rewired, will take anything from 5 to 15 days to complete.

If you need to get your home rewired, make sure you get three quotes so you can source the best price to rewire a house from local electricians registered with a competent person scheme, such as NICEIC or NAPIT. The price to rewire a house will take into consideration the condition of the existing electrics and the size of the property. Make sure you get a comprehensive quote and a detailed breakdown of what will be included in the cost – for instance, check if the price covers moving furniture and re-plastering.

Signs your property needs rewiring

Modern electrical cables are insulated with a PVC coating and will be grey or white. Older cables are black, and will be insulated with rubber. So if your cables are black it could be a sign that you have old electrics. Check your fuse box too because it may need to be replaced. Also known as a consumer unit, a shocking number of homes still have the older type fuse boxes and need to be replaced. Old fashioned fuseboxes have wooden backs. Cast iron switches are another giveaway, as are round light switches, round pin sockets and a bathroom with wall mounted light switches.
