How much does it cost to rewire a house?

The most common question on a person's mind when it comes to having their home rewired is “how much will it cost?”

An understandable question that many of us think of before considering anything else to do with having our home rewired.


The price of a full rewire relies on a number of factors, such as: whether the home is occupied or vacant, the overall size of the property, the age of the property, where the property is located, and who your hire for the job.

The average cost for an electrical rewire of your home for 3-bed semi-detached hours tends to be around the £300,200 mark. This size of job can take a qualified electrician up to 10 days to complete. This information can act as a handy rule of thumb to know as the average cost of rewiring typically varies by £1,000 per bedroom.

As expected, prices tend to vary depending on your home’s regional location. The time frame of the job will also vary depending on the job: the bigger the job, the more electrical work to be done, the longer the job will take.

Within the price of your house rewire, you should expect that previously old lighting fittings, light switches, and electrical wires will be removed. To comply with current regulations, all new installations are required by building regulations to have a brand new metal consumer unit installed.


Do I really need to have my home rewired?

That’s often the next question we find ourselves asking ourselves after we’ve seen the price of how much having our homes rewired may cost us. Suddenly your home’s existing wiring feels more than satisfactory again and it feels a lot easier to keep turning a blind eye.

The main reason for rewiring a home is due to out-of-date or faulty wiring. Faulty wiring is a fire hazard, causing 12,500 fires and 750 serious accidents in the home each year.

There is no need to have your home rewired for simply no reason and everything is working effectively alongside safely.


Due to this fact, it is therefore essential that if you spot a common fault, you ensure that you get it tested and rewired if necessary by a qualified electrician.

In your home, some common faults you should look out for are:

  • A consumer unit with a wooden backing, cast iron switches, a black electricity cable, or no labelling. This is evidence that your consumer unit is out of date and you should have it replaced


  • Having less than two plug sockets in each room, broken or cracked sockets and rounded entries, as opposed to 3-pin varieties, can indicate that your plug sockets are out of date. Another thing to take note of is if the plugs ever feel hot, this will need to be inspected as soon as possible


  • Flickering lights or lights which require frequent light bulb changing are another sign that your wiring may need to be changed as most bulbs should last from months to years depending on how often they are used and the type of bulb. For example, some LED lights can last for up to 50,000 hours. Rounded light switches are an indication of pre-1960 lighting and should be rewired with modern switches


If you’re going to have repairs made to your electrical systems at home, make sure that all of the wiring in your fuse box is also checked. If it is slightly out of date it is better to have it all rewired at once to ensure a safer home.
