Looking for Fuse Board Replacement in Exeter?
If your property still has a rewirable fuse board — one where individual fuse holders contain a thin wire that blows when a circuit is overloaded, requiring you to hunt for fuse wire and refit it — you are working with technology that was largely superseded in residential properties during the 1980s and 1990s. These old boards offer significantly less protection than modern consumer units and are routinely flagged on Electrical Installation Condition Reports as requiring upgrade.
Modern consumer units use miniature circuit breakers (MCBs) instead of wire fuses. MCBs trip instantly when a fault occurs and reset with a simple switch — no fuse wire, no hunting in the dark. More importantly, they incorporate residual current devices (RCDs) that detect dangerous earth faults and cut power in milliseconds, providing the level of shock protection that no old rewirable board can offer.
We book NICEIC-registered electricians across Exeter and Devon for fuse board and consumer unit replacements. Whether you have an old board that keeps blowing, you are selling the property and a surveyor has flagged it, your EICR has returned C2 observations, or you simply want to bring your installation up to current standards, we can help.
Consumer unit replacement is notifiable work under Part P of the Building Regulations. Our engineers self-certify the work to Building Control on your behalf and issue you with a Building Regulations Compliance Certificate before they leave — the document your solicitor will ask for when you sell.
What We Cover
Every type of consumer unit and fuse board replacement work we carry out across Exeter and Devon.
Old rewirable fuse box replacement
The most common job — replacing an old board with wire fuses with a modern RCD or RCBO consumer unit. MCBs replace the wire fuses; RCDs provide shock protection throughout.
RCD consumer unit installation
Dual-RCD or single-RCD split-load boards provide RCD protection across all circuits while keeping costs lower than a full RCBO board. Suitable for most standard domestic properties.
RCBO consumer unit installation
The highest-specification option — each circuit has its own combined RCBO for individual protection and maximum discrimination. If one circuit trips, all others remain live.
Split-load boards
Two-section consumer units where circuits are divided into groups, each protected by its own RCD. A practical balance between protection and cost for most Exeter homes.
Dual-RCD boards
A split-load board with two RCDs dividing the circuits into two protected groups. Standard for most domestic consumer unit replacements in the current period.
Garage and outbuilding consumer units
Separate sub-boards for garages, workshops, and outbuildings. Provides a local isolation point and proper protection for the circuits in the outbuilding.
Part P notification and certification
All consumer unit replacements are notified to Building Control on your behalf. You receive a Building Regulations Compliance Certificate on the day the work is completed.
Completion certificate issue
An Electrical Installation Certificate or Minor Works Certificate is issued for every job, confirming the installation has been tested to BS 7671 on completion.
Who We Help
Homeowners
Whether your old board keeps blowing, a surveyor has flagged it during a sale, or you simply want to bring your installation up to current standards, a fuse board replacement is one of the most impactful electrical upgrades you can make. Every circuit in your home gets proper overcurrent protection and, critically, RCD protection against electric shock. Most Exeter homeowners are surprised at how quickly and cleanly the job is done, and how reassuring it is to know the board is modern and properly certified.
Landlords
An EICR returning C2 observations relating to an old consumer unit puts you under a legal obligation to carry out remedial works within 28 days. A fuse board replacement resolves this and provides the written confirmation your local authority requires. We work with Exeter landlords and letting agents to schedule replacements around tenancies, coordinate access with tenants, and provide all compliance documentation for your property file.
Businesses
Small business premises and offices with outdated distribution boards present similar risks to old domestic consumer units. We carry out commercial board replacements across Exeter and Devon, working around business hours where possible to minimise disruption. If you are adding new circuits — for EV charging, additional office equipment, or a kitchen extension — we can often combine the board replacement with the new circuit installation in a single visit.

Why NICEIC Registration Matters for Consumer Unit Replacement
Consumer unit replacement is one of the most common Part P notifiable jobs carried out in UK homes — and one that is frequently offered by unregistered tradespeople who cannot legally self-certify the work. NICEIC (the National Inspection Council for Electrical Installation Contracting) is the UK's leading voluntary regulatory body for the electrotechnical industry, assessing contractors annually for technical competence.
Only NICEIC-registered electricians can self-certify consumer unit replacement to Building Control under Part P. Without this, the work must be separately notified to your local authority and inspected by a Building Control Officer — adding cost, delay, and potential gaps in your compliance documentation that will cause problems when you sell.
Every engineer we book is NICEIC-registered. We verify this before any booking is confirmed. You can also check any electrician yourself against the NICEIC online register at niceic.com before they begin work at your property.
