Old Fuse Board?

Should I change my old fuse board?

Every year in the UK, electricity causes over half of all accidental domestic fires.  This happens due to misuse or faults with electrical products, including old fuse boards.

Having an old fuse board will usually mean you have old wiring. This does not mean the installation is unsafe, as the wiring and fuse board will comply to the regulations at their time of installation. The problem we often find though is that old wiring over time unfortunately wears out, just like anything else.

Can I upgrade my fuse board without upgrading my wiring?

Modern fuse boards have new switches that are extremely sensitive and if there is old wiring within the property, these switches will not accept the wiring, meaning it can cause the board to trip.

Alternatively, if the wiring in your property is ok, and the water stopcock and gas have been earthed, you will only make it safer by upgrading the fuse board.


So how do I know if my fuse board needs upgraded?

We will not be able to tell from the outside of a fuse board if it is in a satisfactory condition, but we can tell you how old it is.

The only way to tell if the fuseboard needs upgraded is to remove the cover and make a visual inspection and carry out various tests on the installation and report on its condition.

More often than not, old fuse boards will not contain RCD or MCB protection and as such do not offer the same safety cover they were designed for, before we started using as many electrical appliances such as microwaves, ceramic hobs or large capacity showers.

We have seen badly damaged fuse boards that look perfectly acceptable on the outside but were close to causing a fire.

The best thing to do is to have our experts out to view the fuse board (use the contact form above if it is easiest), run their tests and report back to you on the condition of the fuse board and of the electrics within the property.
