A consumer unit replacement swaps an old fuse box or outdated board for a modern unit with RCD and surge protection. We replace consumer units across Manchester, with a free, no-obligation quote first.

Old rewireable fuses, a wooden backboard, no RCD protection, or a board that feels warm or smells of burning are all reasons to upgrade. You may also need a new board to add a circuit for an EV charger, an electric shower or an extension.
New consumer units use RCBOs or RCDs to cut the power quickly if current leaks to earth, along with surge protection and a fire-resistant metal casing. Each circuit is clearly labelled, so it's easy to see which one has tripped and reset it safely.
A new board is only as safe as the earthing behind it. Before fitting, we check your main earth and the bonding to gas and water pipes. If either needs upgrading to meet current regulations, we include it in your quote so nothing comes as a surprise.
We start with a visit to look at your existing board, the number of circuits and the condition of the wiring. Testing at this stage shows whether any circuits have faults that a sensitive new RCD would pick up. You then get a free, no-obligation quote.
On the day, the power is switched off while we remove the old board and fit the new consumer unit. Each circuit is connected, labelled and tested before the power goes back on. You receive an Electrical Installation Certificate, and we notify building control for you.
Call or send us a message about the job. We'll get back to you the same day to arrange a visit.
An electrician looks at the work and gives you a free, no-obligation quote before anything starts.
We complete the job, test everything we've worked on and give you the certificate for your records.
Most replacements take half a day to a full day, depending on how many circuits there are and whether earthing or bonding needs upgrading. The power will be off for most of that time, so we'll agree a start time with you and keep you updated as we go.
New RCDs are more sensitive than old fuses, so they can reveal faults that were there all along, such as damp in a cable or a faulty appliance. That's why we test every circuit before the swap. If a fault appears, we explain it and give you a price before fixing it.
Yes. Replacing a consumer unit is notifiable work under Part P of the Building Regulations in England. As NICEIC registered electricians, we notify building control on your behalf, and you receive a Building Regulations compliance certificate as well as your Electrical Installation Certificate.
It can help. Buyers and surveyors often flag an old fuse box, which can lead to questions or renegotiation. A new consumer unit with a certificate shows the electrics have been updated and tested. Book early so the paperwork is ready to pass to your solicitor.
