How Much Does it Cost to Rewire a House?

Some questions are akin to asking ‘how long is a piece of string?’ This certainly applies in this case as the answer will depend on a number of factors. That’s what we’re going to look at here, so you’ll have a rough idea of what to expect if you think your house needs rewiring.

Different estimates from different electricians

The first thing to bear in mind is that different electricians will charge different prices. Newly qualified electricians are likely to charge less to compensate for their lack of experience. The main rule of thumb here is to ensure you hire someone who is fully qualified. They should be a member of at least one competent person scheme:

  • NICEIC Certification Services
  • British Standards Institution (BSI)
  • ELECSA

Size of the property

This is another key factor to consider when working out a price. Assuming everything else is equal, a four bedroom house will cost more to rewire than a two bedroom house. This is simply because there are two additional rooms that will require rewiring, along with the usual sockets, wiring and light switches required.

The amount of work required in each room

Any estimate for a complete house rewire will also have to take into account the number of sockets and switches required in each room. For example if you wish to keep the existing electrical layout, you will be given one estimate. However if you want to add one additional wall socket in each room, the overall estimate will obviously be higher than it would be otherwise.

Any extras required?

As you can probably tell, there is no such thing as a typical house rewiring job. You might decide this is the perfect time to get a new electric shower fitted. Alternatively you might decide to have your property rewired and to include a fully fitted burglar alarm system as well. These types of changes have a direct effect on the resulting quote you will be given.

Think about the effect the rewire will have on the property as well. If floors need to be taken up and walls channelled out to provide space for the wiring, this will be cheaper to do in an empty building that has yet to be decorated. If you have already spent money decorating your home and then need to have it rewired, you’ll have the additional cost of decoration to add on. This won’t be handled by the electrician of course, but it will be something you need to think about.

It’s wise to get several quotes for the work that needs doing. Before you go this far, make sure you consider whether you want to make any changes to the existing layout as mentioned before. If you are getting everything rewired it makes sense to make changes now, rather than paying for them to be done later.

Now you have an idea of what to expect, you can look for quotes with more confidence.
