A consumer unit and a fuse board serve the exact same purpose (a means of origin for the electrical cabling to be protected and isolated via selected devices (MCB’s,RCBO’s & fuses) within your building). A fuse board is the older term as the board would house ‘fuses’ to protect the cabling. Fortunately, technology has improved over the years and that is why you will tend to see MCB’s (mini circuit breakers) or RCBO’s (residual current devices) installed within your building. Commercial properties also in some cases have large plant rooms with various panels, risers with busbar systems and large switchgear which all needs to be tested. All of these systems combined are at the heart of your electrical installation, which is why we at Sol-Lux Electrical believe and understand that they should be kept ‘healthy’ and in check with current regulations.
Your Consumer Unit…
Is my consumer unit old and does it comply with current regulations? Is it time to replace it with a more modern, safer model? How long will it take to replace? And how much will it cost?
Read on below and you will find out the answers to the following questions and find out if it is time to replace your consumer unit. If you’re still not sure, use our free electrical advice service and we can assist you from the comfort of your own home.
Is my Consumer Unit old and outdated?
If you have a setup of a consumer unit/ fuse board (that looks similar to the image to the left) it doesn’t necessarily mean that your fuse board needs to be replaced. However, we would advise that it should be upgraded to a modern model. Generally this would be because of the following factors:
- Occasionally fuses or MCBs break and need to be replaced (old type devices are hard to come by and often are expensive)
- Older boards tend to have fewer circuits and usually don’t have any spare ways for additional circuits.

What is a MCB and RCD protection and how will it effect my installation?
An MCB is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit.
An RCD is an electrical safety device that quickly breaks an electrical circuit with leakage current to ground. It is to protect equipment and to reduce the risk of serious harm from an ongoing electric shock
The best of both (RCBO)
An RCBO is a residual current circuit breaker with overcurrent protection. It monitors electrical circuits to keep them running safely, disconnecting the circuit if it’s unbalanced. These devices are commonly used where there is a need to combine protection against overload, short circuit and earth leakage currents.
My Consumer Unit is Plastic, is this a problem?
Since regulations changed in 2016, all domestic consumer units installed within a property must be either enclosed in a non-combustible material or housed in a cabinet made from a non-combustible material. Consumer units installed before 2016 don’t need to be replaced. However we advise to do so as a metal clad consumer unit is considerably safer when it comes to risk and spread of fire.
