Fuse Box Upgrades (New Consumer Unit) in Bristol
Your fuse box, the consumer unit in the trade, is the heart of your home's electrics, and an old one is the weak point we find most often. A modern board cuts the power in a fraction of a second when something goes wrong, protecting you from shock and your house from electrical fire.
We test every circuit before the changeover so there are no surprises, fit a quality board with surge protection as standard, label everything clearly and walk you round the new board before we leave. You get your certificate and, as a NAPIT-registered firm, we notify the work for you. Most upgrades are finished in a day.

Your TVs, computers and appliances are protected from damaging power spikes as standard.
Certified and notified

Fuse box upgrades questions, answered
How much does a fuse box replacement cost in Bristol?
Most consumer unit upgrades around Bristol land between £450 and £900, depending on the board and your circuits. You get an exact fixed quote 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. We plan the changeover so the disruption to your home is as short as possible.
Why does my new fuse box trip when the old one never did?
Modern fuse boxes catch faults the old one silently ignored. That's exactly the protection you're paying for. We 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, we'll tell you so. We'll never sell you a board you don't need.
