Consumer Unit Upgrades (Fuse Box Replacement)
Your fuse box (the consumer unit, in the trade) is the heart of your electrics, and an old one is the weak point I find most often on call-outs. A modern board cuts the power in a fraction of a second when something goes wrong, protecting you from shock and the property from electrical fire.
I test every circuit before the changeover so there are no surprises, fit a quality board with surge protection as standard, label everything clearly and certify the work under my NICEIC registration. Most upgrades are finished in a day.
What's included
Circuits tested first
Every circuit is inspected and tested before the swap, so hidden faults are found and priced honestly up front.
Protection on every circuit
Every circuit gets its own safety switch, so a fault in one room never blacks out the whole property.
Surge protection built in
Your TVs, computers and appliances are protected from damaging power spikes as standard.
Certified and labelled
A clearly labelled board, tested, certified and walked through with you so you know exactly what does what.
Fuse boxes questions, answered
How much does a consumer unit upgrade cost?
Most consumer unit replacements in London land between £600 and £1,100 for a typical home, depending on the board and the number of circuits. Older installations that need extra remedial work sit higher. I confirm one fixed price for your exact job before any work starts, so there are no surprises on the invoice.
How long will the power be off?
Usually just a few hours in the middle of the day. I plan the changeover so the disruption to your home stays as short as possible.
Why does my new fuse box trip when the old one never did?
Modern boards catch faults the old one silently ignored. That's exactly the protection you're paying for. I test every circuit at changeover so anything the new board flags gets found and fixed properly.
Do I actually need a new fuse box?
If yours has rewireable fuses, a wooden back or no safety switches (RCDs), it's worth upgrading. If yours is fine, I'll tell you so. I never sell a board that isn't needed.
