While these terms are often used interchangeably, there are a few differences between the two. Below is a summary of each:

Fuse box

• In the past, fuse boxes were the most popular choice

• Work by using fuses that melt if there are any electrical issues

• Less safe than consumer units as the fuses don't melt and cut the power instantly, it takes a few seconds

• Greater risk of fires

Consumer units

• More popular today

• Work by detecting issues in your home’s electrical circuit and switching off your electricity

• Safer than fuse boxes, the power is cut instantly

• No need to replace melted fuses, just flip a switch to turn your home's electricity back on

• Less risk of fires

Types of consumer unit

There are a few different types of consumer units so it's worth considering all your options before making a choice. The most common types of consumer units include:

• Full loaded consumer unit

• Split load consumer unit

• Shower consumer unit

• Garage consumer unit

• High integrity consumer unit

• RCD dual split consumer unit

• Domestic switch fuse

If you need a new fuse box, you’re probably wondering how much you need to budget for this job. The amount you pay for your fuse box will be affected by the following variables:

• Type of fuse box - There are a range of different fuse boxes, each with its own price.

• Current set up - If you need to make big changes or your current setup is in poor condition, this will increase the amount you pay.

• Size of property - Larger properties will need more powerful fuse boxes which are more expensive.

• Electrical inspection - If your home wiring hasn't been checked in a while, you may need an electrical inspection to ensure it’s safe. This will cost an extra £120 - £300.

• Extra work - If you need extra work doing, e.g. adding new wiring or sockets, this will push up the price you pay.

• Location - Labour costs vary depending on where you live in the UK.
