Consumer split-load units are priced between £60 or £130.

Domestic Switch Fuse Cost

For rewiring a three-bedroom semi-detached home, an electrician can provide a price range of about £750 to £1050 and an attached home with four bedrooms could run £1350 plus.

  • If your walls were damaged by the removal and installation of wiring, you could require an expert plasterer, who is charged between £75 to £125 to repair the wall, and it can cost up to £150 for replastering walls.
  • Additionally, you will need to pay a painter or decorator to wallpaper or paint your walls. This can cost between £150 or £200 each day.

How Long Does It Take to Rewire a House?


Wiring a home is a huge project that takes a considerable amount of time. The time will be determined by the kind and dimensions of the house and the state of the wiring.

When the wire is in poor condition the safety precautions must be implemented to ensure that the electrician is not damaging themselves while removing the wire.

But on average?

The typical timeframe for rewiring the wiring of a single-bedroom apartment is approximately four days, while an apartment with two bedrooms could take as long as 5 days in order to finish.

More spacious homes like three-bedroom semi-detached homes typically require 6 to seven days to wire and a four-bedroom detached can take anywhere from 7 to 9 days.


Q: How disruptive is rewiring a house?

A: House rewiring is quite an extensive job which can take up to 10 days to complete – but this will depend on the size of your home.

In short, it can create quite a mess! It might involve lifting up floorboards or carpet, removing wallpaper, and ripping out light fixtures to remove old wiring.

While your house is being rewired, an electrician will also need to ensure that the electric mains are switched off to prevent any shock incidents. This means that you may not be able to access any electricity – so no lighting or internet!

Because of all this disruption, the majority of homeowners move out of their home while it is being rewired – as it allows the job to be finished quickly.

If this is not possible, you will need to ask your electrician if it is possible to set up a space in one room where you can keep everything you need and not be disrupted. As this means the electrician will not spend as much time in the property, the rewiring could take from a few days up to a few weeks longer than expected.

Q: How can you tell if a house needs rewiring?

A: There are various signs that your house may need rewiring.

Common signs include: if your circuit breakers trip regularly, you experience any shocks from light switches or plug outlets, flickering or dimming lights, or noticeably damaged wiring and cables.

Q: How often does a house need rewiring?

A: House wiring usually lasts around 20 years if there are no complications with circuit breakers, sockets, light switches, or any other electrical installations.

In some cases, you may not need new wiring for up to 40 years. However, cable insulation will eventually begin to wear down – which will start to affect all electrical devices in your home.

This will cause you to use more electricity, leading to higher energy bills – while also making your home unsafe.

Q: Can you rewire a house yourself?

A: It is possible to rewire your house yourself if you are on a budget. However, you must have all the electrical work checked by a qualified electrician who is listed under the competent persons scheme.

This will enable the work to be approved under Part P building regulations to be deemed safe and compliant.

If you have no previous experience working with wiring or electrical installations, then you should avoid doing the job yourself. It can be very dangerous and more expensive in the long run if you make a mistake.

Q: What does a house rewire involve?

A: There are two stages involved in house rewiring.

The first fix stage is where the old wiring is removed and replaced with new wiring that is safe and compliant.

The second fix stage involves connecting everything up to the mains and making it live.

Once everything is installed, a qualified electrician will then conduct checks on all electrical installations to ensure that they are safe.

Once everything is deemed compliant, they will issue an electrical safety certificate to the homeowner to confirm that the work is safe.
