Consumer Unit
Replacement Bournemouth
Upgrade your home's safety. We replace outdated, dangerous fuse boards with modern, 18th Edition compliant consumer units featuring full RCBO and Surge Protection (SPD) as standard.
When do you need an upgrade?
Old Fuse Board
If you still have rewireable ceramic fuses or an old plastic-cased board, it lacks the critical safety features required for 2026 standards.
Constant Tripping
Breakers that frequently trip without an obvious cause often indicate an overloaded or failing consumer unit that needs replacement.
No RCD Protection
Modern boards use RCDs to prevent lethal electric shocks. If your board lacks a 'Test' button, you are at significant risk.
Major Renovations
Adding a new kitchen, extension, or EV charger often requires a complete consumer unit upgrade to handle the increased electrical load.

Self-Assessment Checklist
Assessment Result
Your board may be functional, but if it's over 15 years old, a safety inspection is recommended.

Core Scope of Works
What is included?
Removal of your old fuse board and installation of a new, fire-rated metal consumer unit. We utilize premium brands like Hager or FuseBox, fitted with a main switch, Surge Protection Device (SPD), and individual RCBOs for every circuit. This ensures maximum safety and selectivity.
Timeframe
Typically 4–6 hours including full dead and live testing of every circuit in the property.
Certification
You receive your digital NAPIT Electrical Installation Certificate (EIC) immediately upon completion, and we handle the Building Control notification.
Surge Protection Standard
Surge Protection as Standard
Many contractors treat Surge Protection Devices (SPD) as an optional extra. At SC Electric, we believe they are essential for modern living.
We include an SPD in every board we install at no extra cost. This protects your sensitive electronics—TVs, computers, and smart home devices—from damaging voltage spikes caused by lightning or grid switching.
Complex Board Upgrades
Not every replacement is straightforward. We are experienced in handling non-standard installations across Bournemouth.
Tight Spaces & Recessed Boards
Working in small cupboards or recessed wall cavities requires precision. We select compact, high-quality boards that fit your space without compromising on safety or access.
Multiple Boards & Sub-Mains
For larger properties or those with outbuildings/annexes, we design and install coordinated distribution systems with correct discrimination between boards.
Commercial Distribution
We provide heavy-duty 3-phase distribution board upgrades for commercial premises, ensuring your business meets all statutory safety requirements.
