Why upgrade your fuse board
A modern consumer unit protects your home in ways an old fuse box cannot.
Better protection
RCD protection that cuts the power in a fraction of a second if current leaks to earth, helping protect against electric shock
A non-combustible case, usually metal, as current wiring regulations call for in homes, to help contain a fire
Easier to live with
Every circuit clearly labelled, so you know what each switch controls
Spare space for future circuits, such as an EV charger or a new shower
Signs your fuse board needs replacing
If any of these sound familiar, it is worth having your fuse board checked.
Old wire fuses
It has fuses with fuse wire rather than switches.
No RCD
There is no RCD, usually a switch marked with a test button.
Worn or damaged
It sits on a wooden board, has a cracked plastic case, trips often, buzzes or feels warm.
Bigger changes planned
You are adding an EV charger, an electric shower or an extension, or an EICR has recommended replacing it.

Fuse board questions
-
They are the same thing. Fuse box is the older name, from when they held wire fuses. A modern consumer unit uses switches called circuit breakers and RCDs instead.
