What decides the cost of a house rewire?

By Ian Walsh, Renew Electrical, 10 November 2026

The cost of a house rewire depends on the size of the house, the state of the old wiring and fuse board, how easy the house is to work in, and anything you add while the walls are open. Ian prices it in the house and gives you an itemised quote.

If you have asked two electricians for a number and got two very different answers, this is why. A rewire is a job, and the job is different in every house.

The four things that move the price

  1. The size of the house. More rooms means more circuits, more points and more cable.
  2. The state of what is already there. The old cable and the fuse board are checked at the survey, so what they need is in the price from the start.
  3. How easy the house is to work in. Access to the attic and under the floors, how the walls are built and how many floors there are all change the work.
  4. What you add while the walls are open. Extra sockets, outside lights, or a supply for an EV charger are simplest to do while the cable is going in.

Full or partial

A full rewire and a partial one are different jobs with different prices. Ian does both and tells you which your house needs.

What the quote should look like

An itemised quote: the job broken into its parts, so you can see where the cost goes and compare it properly. Ask any electrician you are comparing for the same thing. Ian gives one before any work starts.

What is included

The wall chases are plastered and the house is left as it was before. Painting is not included. You get a Safe Electric completion certificate at the end.

Why there is no price on this site

Because a number on a website would be a guess about your house. The free survey is how you get a real one.

Quick answers

Can you give me a price from a form or a photo?

No. The price depends on what is in the house, so Ian prices it at a free survey, standing in it.
