Whether you are replacing an ageing fuse board, sorting issues found during an Electrical Inspection & Test, or getting ready for an EV charger or heat pump, we handle the job with safety and minimal disruption in mind.
A fuse box upgrade in Nottingham is one of the most worthwhile pieces of electrical work you can have done. As part of our wider Electrician Nottingham and Commercial Electrician Nottingham services, we help households and businesses across Nottinghamshire bring their electrics up to current standards.

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 (SPD) to guard sensitive equipment against voltage spikes. The result meets current 18th Edition (BS7671) standards and is far better suited to modern loads like induction hobs, power showers and EV chargers.
For commercial premises, the case is just as strong. Offices, shops and warehouses run more circuits and more equipment than they used to, and an old board that keeps tripping costs you time and money every time it does.
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.
How much does a consumer unit upgrade cost in Nottingham?
A few honest numbers, because the “it depends” answer isn’t helpful.
For a standard domestic upgrade (replacing the board, RCBO protection on each circuit, full testing and certification), most jobs land between £550 and £850. Larger homes with more circuits, or specs that include AFDDs and SPDs, can push £900 to £1,200.
For commercial premises, pricing depends on the number of circuits, the existing condition, whether work is done in or out of business hours, and any wider remediation that comes out of the assessment. We’ll always give you a fixed quote in writing before any work starts.
What pushes the price up: split-load boards being swapped for fully RCBO units, additional circuits, three-phase supplies, dated wiring that needs minor remediation, or asbestos in the original board backing (yes, still occasionally found in older properties).
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-Outservice. Call us on 0115 990 3308 and we’ll triage it on the phone.

Honest scoping, no upsell
If a full upgrade isn’t needed, we’ll say so. We’ve talked plenty of customers out of a £900 spend when an £180 EICR or a few RCD swaps were the right answer. Repeat business and Google reviews matter more to us than squeezing one job.
