LB ElectricalsConsumer unit and fuse box replacement in Doncaster
Your consumer unit — the fuse box — is the heart of the house's electrics. Every circuit runs through it, and it's the thing that should cut the power fast when something goes wrong. Older boards with rewireable fuses, or units without RCD protection, don't do that job to the standard a modern unit does.
We replace consumer units across Doncaster, Sheffield and the surrounding towns. It's usually a one-day job, and it's one of the most cost-effective safety upgrades an older home can have.
What's included
A board change is more than swapping one box for another. Before the new unit goes live, every circuit it feeds is inspected and tested — this is often the moment hidden problems in older wiring show themselves, which is exactly what you want to happen while an electrician is standing in front of the board.
Work carried out in line with applicable UK wiring regulations and good industry practice.
- A modern consumer unit with RCD protection
- Every circuit tested before and after connection
- Circuits identified and clearly labelled — no more guessing which fuse is the kitchen
- Earthing and bonding checked, and upgraded where needed
- An Electrical Installation Certificate is issued on completion
Our process
Most board changes run like this:
- A look at the job — photos of your current board are often enough to quote from; a quick visit if not.
- Fixed quote — including any earthing or bonding upgrades we can see are needed, so the price doesn't creep on the day.
- The work — power off, old unit out, circuits tested, new unit fitted and energised. Usually done in a day.
- Paperwork — an Electrical Installation Certificate is issued on completion, with a test record for every circuit.
- Tidy-up — the old board and packaging leave with us, and every circuit is labelled before we go.
How pricing works
The price of a board change depends on the house more than the box. Send a photo of your fuse box with the quote form — it's often all we need to give you a firm price.
- How many circuits the new unit needs to take
- The condition of the existing wiring — faults found on test need putting right before a circuit can be reconnected
- Whether earthing and bonding to gas and water need bringing up to standard
- Where the board lives — an accessible hallway cupboard is quicker than the back of a Victorian cellar
- Anything you'd like doing at the same time, like an extra circuit for a garden building
Signs your fuse box is due for replacement
Not sure whether yours needs doing? These are the things we look for:
An old board isn't automatically dangerous, and we'll tell you straight if yours is fine. But if you're planning an extension, a loft conversion or a rewire, the board is where the conversation starts.
- Rewireable fuses — the type with fuse wire — rather than switches
- No RCD protection: no test button anywhere on the board
- A wooden backboard, cast-iron switchgear or a tangle of add-ons wired in over the years
- Trips or blown fuses you can't explain
- Buzzing, heat or scorch marks around the unit — switch things off and call us about that one today
Frequently asked questions
How long does a consumer unit replacement take?
Usually a day. The power is off for most of it, so plan around that — a flask of tea, or pick a day you're out. We cover Doncaster, Bentley, Sheffield and the towns around them.
Will you find problems with my wiring?
Sometimes, yes — testing every circuit is part of the job, and older wiring can hide faults that only show up under test. If we find something, we'll show you, explain the options and price the fix before doing anything. No extra work happens without your say-so.
Is an old fuse box illegal?
No — there's no law saying an old board must be replaced. But a modern unit with RCD protection disconnects faults far faster, and if you're having other electrical work done, or letting the property out, upgrading is usually the sensible moment.
What paperwork do I get?
An Electrical Installation Certificate is issued on completion, along with the test results for every circuit on the new board. If you're a landlord in Rotherham or Sheffield, pairing a board change with an EICR in one visit often makes sense.
