If you’re living in an older property in Rotherham or South Yorkshire, there’s a good chance your electrical wiring is due for an upgrade. One of the first questions homeowners ask is: how much will a rewire actually cost? The answer depends on several factors, but this guide will help you understand what’s involved and what affects the price.

What Affects the Cost of a House Rewire?

No two rewiring jobs are exactly the same. The cost depends on the size of your property, how many rooms need rewiring, the number of sockets and light fittings you want, the age and condition of the existing wiring, and whether you need a new consumer unit (fuseboard) as part of the work. A small two-bedroom terrace will naturally cost less than a large four-bedroom detached house.

What Does a Full Rewire Include?

A full house rewiringe typically includes removing all existing wiring and replacing it with modern twin-and-earth cable, fitting a new consumer unit with RCD protection, installing new sockets and light switches throughout the property, fitting new light fittings or preparing ceiling roses, installing smoke alarms as required by current Building Regulations, and issuing an Electrical Installation Certificate (EIC) once the work is tested and signed off.

Signs Your House Needs Rewiring

Not every home needs a full rewire. But if your property was built before the 1980s and hasn’t been rewired since, it’s worth getting an inspection. Warning signs include old round-pin sockets, rubber or lead-sheathed cables, a dated fuse box without RCD protection, flickering lights, blown fuses, or a burning smell from sockets. If you notice any of these, you should have a qualified electrician carry out an EICR (Electrical Installation Condition Report) to assess the condition of your wiring.

Do I Need to Move Out During a Rewire?

Most people can stay in their home during a rewire, though it can be disruptive. Floors may need lifting, walls will need chasing for new cables, and you’ll be without power to certain rooms at various stages. A typical full rewire takes between five and ten working days depending on the size of the property. Some homeowners prefer to stay with family or friends for part of the work, but it’s not essential.

Will I Need to Redecorate After a Rewire?

Yes, some redecoration will be needed. When new cables are run through walls, channels (chases) are cut into the plaster. These are filled and left flush, but you’ll need to repaint or wallpaper over them. Many homeowners use a rewire as an opportunity to refresh the whole house. If you’re planning a renovation anyway, it makes sense to rewire at the same time while walls and floors are already being disturbed.

Why Use a NAPIT-Registered Electrician?

A house rewire is notifiable work under Part P of the Building Regulations. This means it must be carried out by a qualified electrician registered with a competent person scheme such as NAPIT. Using a registered electrician means the work is inspected, tested, and certified to British Standards. You’ll receive an Electrical Installation Certificate, and the work is automatically notified to your local Building Control. This is important when it comes to selling your home or making an insurance claim, as non-certified work can cause serious problems.
