Your fuse board, or consumer unit, is the heart of your electrics. It splits the supply into circuits and protects each one. An old fuse box with rewirable fuses or no RCD protection does the bare minimum; a modern consumer unit can cut the power in a fraction of a second if someone touches something live or a fault develops.

We replace old fuse boxes and outdated consumer units across the Wirral, Merseyside and Chester with modern boards built to BS 7671, the 18th Edition wiring regulations. Every circuit is tested before and after, and you get an Electrical Installation Certificate with the work registered under Part P.

When a fuse board upgrade makes sense

You do not have to wait for something to go wrong. These are the usual reasons to upgrade:

  • Rewirable fuses with fuse wire
  • No RCD protection
  • A wooden-backed or plastic fuse box
  • Breakers that trip for no obvious reason
  • Signs of heat, scorching or buzzing
  • Adding an EV charger or electric shower
  • A kitchen, extension or loft conversion
  • An EICR that recommends it

What a modern consumer unit gives you

RCD protection. Residual current devices watch for current leaking to earth, the kind of fault that gives someone a shock, and switch off almost instantly. Current regulations require them on most circuits in a home.

RCBOs where they help. An RCBO protects one circuit on its own, so a fault on the kitchen sockets does not plunge the whole house into darkness. We will explain the options and fit what suits your home.

A non-combustible enclosure. Consumer units in homes now have to be made of non-combustible material, usually steel, and we assess whether surge protection is needed, as the 18th Edition requires.

A new board is also the foundation for bigger jobs: most EV charger installations and electric showers need a spare way and proper protection.

How a fuse board change works

  1. Look and quote

    We check the existing board, the earthing and the circuits it feeds, then give you a clear written quote.

  2. Test first

    On the day, we test the existing circuits before anything changes, so hidden faults are found up front.

  3. Fit the new board

    The old unit comes out, the new one goes in, and every circuit is connected, labelled and checked.

  4. Certify

    Full testing, an Electrical Installation Certificate, and Part P notification handled for you.

Why we test before we start

Older fuse boxes are forgiving of faults that a modern RCD will not tolerate. A damp outside light, a nail through a cable years ago or a neutral shared between circuits can sit unnoticed for decades, then trip a new board the moment it is switched on.

That is why we test the existing wiring before we swap anything. If we find a problem, we tell you straight away, explain what it means and what it would take to put right, and agree it with you before carrying on. If the testing shows the wiring itself is past its best, we will say so honestly and talk you through whether a part or full rewire is worth considering first.

At the end, every circuit is clearly labelled, so if something ever trips you can see at a glance which part of the house it is. We show you how the RCDs and breakers work, how to use the test button, and what to do if something switches off.

We check the main earthing and the bonding to your gas and water pipes too. If they are missing or undersized, that is part of doing the job properly.

Never work on a fuse board yourself

The incoming cables in a consumer unit are live even with the main switch off. Replacing a board is notifiable work under Part P and must be done by a registered electrician. If your board is scorched, buzzing or smells hot, leave it alone and call us on 07845 087406.

Fuse board questions

All questions

Are you a registered electrician?

Yes. We are NAPIT approved and registered under the Part P competent person scheme, so notifiable work is certified and registered with building control for you. Every job is tested and you get the right certificate for it: an Electrical Installation Certificate for new circuits and rewires, a Minor Works Certificate for smaller jobs, or an EICR for an inspection.

Why should I upgrade my fuse board?

Older fuse boxes often have no RCD protection, which is what cuts the power in a fraction of a second if someone touches something live. A modern consumer unit adds that protection, makes faults easier to find and is usually needed before adding new circuits such as an EV charger or an electric shower.

How long does a consumer unit change take?

Usually most of a day, including testing every circuit. The power is off while we work, and we tell you before we start if the testing finds a fault on an existing circuit that needs putting right.
