Cost Of Rewiring

How Much Does It Cost To Rewire A House

Old or faulty wiring can be very dangerous, leading to electric shocks, frequent power trips, and even house fires—over half of all accidental house fires are caused by electrical problems. If you’re wondering, "How much does it cost to rewire a house?", the cost depends on things like the size of your home.

It might seem that rewiring a small 2-bedroom house would cost less and be easier than rewiring a larger 3-bedroom house, but there are other factors to think about.

Remember, rewiring isn’t just an option; it’s something you must do—especially if your home has old or faulty wiring that needs to be replaced. So, how much does it cost to rewire a house? MANN ELECTROTECHNICAL LTD has a guide that explains everything you need to know to keep your home safe.

How Can I Tell If My Home Needs Rewiring?

If your home is over 25 years old and hasn’t been rewired during that time, it’s a good idea to get an inspection to make sure it meets Part P of the Building Regulations. After that, it’s recommended to have the wiring checked for safety every 5-10 years.

Some signs that your home might need rewiring include:

An old wooden fuse box (consumer unit), or switches made of cast iron or round plastic.
Outdated cable colors and no RCD (a device that protects you from dangerous electric shocks).
Wiring made from rubber, fabric, aluminum, or lead.
Getting small electric shocks when using appliances.
Plugs that get hot when in use.
Discolored wiring or fittings (often caused by overheating).
Crackling or buzzing sounds.
Electricity cutting out (tripping) regularly.

The Cost To Rewire A Flat Or Maisonette

Homeowners use garages differently, and needs vary. Adding lighting, sockets, or a fuse board can raise costs. The average rewire is £500 to £1,000 + VAT.
