If your house is fitted with an old fuse box, you should look to replace it now to prevent possible fire damage.


Fuse boxes are no longer compliant with current electrical regulations.  Consumer units are the modern and safer version of fuse boxes. 

A fuse box and a consumer unit both distribute electricity in your house through multiple circuits and instantly turn the power off whenever a power overload occurs on one of the circuits, which is commonly known as “tripping”. 


The difference between a fuse box and a consumer unit is that a fuse box uses fuses instead of circuit breakers.  The fuse in a fuse box contains a wire which will melt if there is an electrical overload and make the circuit trip and switch the power off.  A consumer unit will switch the power off when ‘tripping’ occurs using the circuit breaker linked to the overloaded circuit. It will turn itself to the position OFF, making the faulty circuit easily identifiable. Once the circuit is fixed, the circuit breaker can be switched back on and the power restored.

When should you replace your Fuse Box


Homes over 20 years old – Homes with older fuse boxes are unable to support today’s need of higher wattage due to the demand for energy in modern appliances which is now higher. This means that in such a situation, a replacement or upgrade to a new consumer unit should be carried out.


Heat – When you notice the fuse box or consumer unit is warmer than normal, then this is a sign of overloading or improper installation.


Strange burning Odour – If your fuse box or consumer unit smells like it’s burning, it could be a sign that the wires are not properly connected or something else.


Frequent Firing – If your fuse box or consumer unit catches fire constantly, it must be replaced immediately at this stage.


Sparking/Tripping – If your fuse box or consumer unit is sparking or constantly tripping when switches are turned on or when using devices, then this is a sign of some loosening of a connection within the circuitry.


NB: If you spot any of these warning signs, call our expert electricians to get the best experience when rewiring your property.



How much does it cost to replace or upgrade a fuse box or electrical consumer unit?

The costs of replacing a fuse box or upgrading a consumer unit to a more recent one can vary greatly as this will depend on many factors such as:

1.    Which type of consumer unit is needed 

2.    The number of circuits required

3.    How old the exiting installation is

A  typical replacement from old fuse box to a new consumer unit (Labour, parts supply & fit) will cost between £485 and £850 and will include:

·         A Consumer unit

·         NICEIC Electrical installation certificate and part P notification to building control


The quote in this example does not include the earth & bonding check which need to be carried out before the replacement takes place. The Earth and bonding inspection will establish if there are any faults in the existing installation which need to be addressed before the fuse box can be replaced..
