Consumer Unit Upgrades
Nottingham
An outdated fuse box does more than trip at the worst moment. It can leave you without reliable shock protection, struggle with the demands of modern appliances, and fail the safety checks that landlords, buyers and insurers increasingly ask for.
We carry out consumer unit upgrades in Nottingham for both homes and commercial premises, whether you're replacing an ageing fuse board, sorting issues found during an inspection, or getting ready for an EV charger or heat pump.

Consumer unit and fuse box upgrades in Nottingham
Your consumer unit, still widely called the fuse box, is the heart of your electrical system. It splits the incoming supply into circuits and protects each one. If yours is old, damaged or no longer suited to how the property is used, it affects everything from day-to-day reliability to your safety.
Older fuse boxes often rely on rewireable fuses and offer little or no protection against electric shock. A modern consumer unit upgrade changes that: today's boards use RCDs and RCBOs to cut the power the instant a fault is detected, sit inside a metal enclosure for better fire containment, and can include surge protection to guard sensitive equipment. The result meets current 18th Edition (BS7671) standards and suits modern loads like induction hobs, power showers and EV chargers.

What's included in our Consumer Unit Upgrade service
Initial Assessment
Every consumer unit upgrade starts with a careful look at your existing setup. We check the condition of the current fuse board, how the system is being used, and flag anything that affects safety, reliability or capacity. Where it makes sense, we recommend an EICR first, so we know the condition of the circuits before any work begins, which helps avoid surprise costs later.
Safe Removal & Installation
We safely isolate the supply before removing the old unit and fitting the new one. The replacement board is chosen to suit the property, whether that is a domestic fuse box upgrade or a larger commercial installation, so the system is ready for the demands placed on it.
We isolate, remove the old board, and install the new one
The power has to come off while we work, typically for 4 to 6 hours on a domestic upgrade. For commercial sites where downtime is a problem, we'll plan the job around your operating hours, and bring temporary supply where it makes sense.
We test, certify, and notify
Every circuit is tested under the 18th Edition regulations. You get an Electrical Installation Certificate at the end, and we notify building control on your behalf where required, so the work is signed off and on the books.
We tidy up and explain everything
You'll get a labelled board (so when something does trip, you know which circuit), the certificate in your inbox, and a plain English summary of anything else we'd recommend looking at. Sometimes that's a full Part or Full Rewire if the existing cabling is past its best. Often it's nothing.
What a consumer unit upgrade actually involves
Most jobs follow the same shape, whether it's a three-bed semi in West Bridgford or a small industrial unit off Castle Boulevard.
When you may need a consumer unit upgrade
A few honest numbers, because the "it depends" answer isn't helpful. A standard domestic upgrade (RCBO protection on each circuit, full testing and certification) typically lands between £550 and £850; larger homes or specs with AFDDs and SPDs can push £900 to £1,200. Commercial pricing depends on circuit count and whether work is in or out of hours. We'll always give you a fixed quote in writing before any work starts.
Need help quickly?
For most consumer unit jobs we can be on site within a few days, sometimes the same week. For genuine emergencies (burning smell, sparking, board failure leaving you without power), we run a 24/7 Emergency Electrical Call-Out service. Call us and we'll triage it on the phone.
