Cost to replace a consumer unit in the UK

Expect to pay £400 or more to replace the consumer unit in your home.

A qualified electrician will usually take a day to replace a consumer unit in your home depending on the size of the property and the complexity of the installation. Initially a EICR is required to understand the condition of your electrical network and may have already been done which flagged the replacement of the consumer unit was necessary. 

Currently the average daily rate of an electrician in the UK is around £240. If an inspection is also required then the price will have to include that which is currently around £100 but this also depends on the size of your property and the complexity and age of the network.

Consumer unit cost

There are different types of consumer units depending on where its fitted. For example you may need one in your garage that it seperate from the houses consumer unit but is ultimately connected to it. This is a smaller unit and does not take as long to install. Alternatively you may have a large property that would suit a high integrity consumer unit that seperates mission critical circuits from the less important. Either way the principle is the same and is much safer than the traditional fuse box.

Type of consumer units

  • Garage consumer unit
  • Shower consumer unit
  • Full load consumer unit
  • Split load consumer unit
  • RCD dual split consumer unit

Which ever type of unit you require you will expect to pay £100 - £300  for a consumer unit in your home. Additional new circuits for things like EV charger installation will cost more but this is a good time time to make sure you have all the electricity needs for the appliances in your home.
