Fuse Box Replacement (New Consumer Unit)
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. That protects 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 and label everything clearly. Most swaps are finished in a day, with the test results in your hand before we leave.
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 house.
Surge protection built in
Your TVs, computers and appliances are protected from damaging power spikes as standard.
Labelled and tested
A clearly labelled board, tested circuit by circuit, with the results in writing for your records.
Fuse boxes questions, answered
How much does a new fuse box cost in King's Lynn?
A straight swap on a typical West Norfolk home usually lands between £450 and £800, depending on how many circuits you have and what we find behind the old board. You get one fixed price before we start, with 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.
Is my old fuse box dangerous?
Not always, but old rewireable fuses and boards with no safety switches give you far less protection than a modern unit. If you're unsure, we'll take an honest look and tell you straight whether it needs replacing or can safely stay.
