Consumer UnitsWhen Should You Upgrade Your Fuse Board?
The consumer unit is the control point for the circuits in your property. Older fuse boards can still be present in many homes, but they may not offer the same modern protection, circuit organisation or convenience as a newer consumer unit.
Key points
Quick summary
Common reasons to upgrade
A consumer unit upgrade may be discussed when a property has older rewirable fuses, poor circuit labelling, limited protective devices, repeated tripping issues or planned electrical changes such as new sockets, kitchen works, outdoor power or EV charging.
Why RCD protection matters
RCD protection is designed to reduce the risk of electric shock by disconnecting the supply when certain faults are detected. Modern consumer units can provide a better level of protection and circuit separation than many older fuse boards.
What gets checked first
Before replacing a consumer unit, the existing circuits and installation condition should be reviewed. This helps identify faults or defects that may need resolving before, during or after the upgrade.
Best time to upgrade
The best time to review a fuse board is often before renovation work, before adding new circuits, after an unsatisfactory EICR, or when the current setup is causing regular issues.
Common QuestionsIs a fuse board the same as a consumer unit?
Many customers use both terms. A consumer unit is the modern name for the unit that controls and protects the circuits in a property.
Will I always need a full rewire with a new consumer unit?
Not always. The existing wiring needs to be assessed so any defects can be identified before the work is planned.
Can I send a photo for a quote?
Yes. Send a clear photo of the fuse board, meter area and surrounding space with your location and a short description of the work needed.
