Fuseboard Upgrades
Why your fuseboard matters more than you think
Your fuseboard (or consumer unit) is the control centre of your electrics. It splits power into circuits and is meant to cut the supply instantly when something goes wrong.
Older fuse boxes with rewireable fuses or no RCD protection can't do that job well. They may not trip quickly enough to prevent a shock, and they offer little protection against the faults that cause electrical fires.
You may need an upgrade if your board has ceramic fuses, a wooden back, no RCDs, constant nuisance tripping, scorch marks or a plastic enclosure in an area where a metal one is now required. An EICR will often recommend an upgrade.
Replacing a consumer unit is notifiable work. It must be done by a qualified, registered electrician, with every circuit tested and a certificate issued. K.Maguire Electrical is NAPIT registered and has fitted consumer units in kitchens, extensions and full rewires across Cumbria.
Don't leave it
The risks of an outdated fuseboard
An old board might still switch the lights on, but that doesn't mean it will protect you.
Slower fault protection
Rewireable fuses can be fitted with the wrong rating and may not disconnect fast enough.
No shock protection
Without RCDs, touching a live part can be fatal before the supply is cut.
Fire from overheating
Worn connections and old enclosures can overheat, especially with modern loads.
Blocks other upgrades
EV chargers, solar and new circuits often can't be added safely to an old board.
Common mistakes we see
- Replacing a fuse with a higher rating
- Ignoring repeated tripping
- Having a board fitted without full circuit testing

In detail
Consumer unit upgrades explained
Not all consumer units are the same. Here's what we consider when upgrading yours.
RCDs, RCBOs and MCBs
MCBs protect circuits against overload. RCDs protect people against shock. RCBOs combine both on each circuit, so one fault won't take out other circuits. We'll recommend the right arrangement for your home and budget.
Metal enclosures
Current regulations require non-combustible enclosures in domestic properties, so new consumer units are typically metal-clad.
Surge protection
Surge protection devices help protect sensitive electronics from voltage spikes and are often required on new installations.
Earthing and bonding
A new board is only as safe as the earthing behind it. We check main earthing and bonding and advise if upgrades are needed.
Upgrades during kitchens and rewires
Consumer units are frequently replaced alongside kitchen refits and rewires, as several of our customer reviews mention.
Commercial distribution boards
Businesses may need larger or three-phase distribution boards. Work is planned to reduce downtime for your premises.
Helpful guide
How to tell if your fuseboard needs upgrading
Open the cover and have a look. If you see ceramic fuse carriers with wire inside, a wooden backboard, or switches with no 'test' button, your board is likely to be well out of date and probably lacks RCD protection.
Pay attention to behaviour too. A board that trips repeatedly, smells of burning, feels warm, or makes buzzing noises needs checking urgently. So does any board with scorch marks or a cracked case.
Consider what you plan to add. EV chargers, solar panels, battery storage, electric showers and new kitchen circuits all need spare capacity and suitable protection. If your current board is full or old, an upgrade now saves a second visit later.
If you're unsure, an EICR gives a definitive answer. The report will state whether your consumer unit and protective devices are adequate, and if an upgrade is recommended you'll know exactly why.
