Your fuseboard (also known as a consumer unit) is the heart of your electrical installation. It’s the point where all the wiring in your home or business is controlled and protected. While many people rarely give their fuseboard much thought, keeping it up to date with current regulations is vital for both safety and compliance.
Safety First – Why Regulations Matter
Electrical regulations aren’t there to make things complicated—they’re there to protect you, your family, and your property. Over time, safety standards evolve to address new risks and ensure that electrical systems can cope with modern demands. An outdated fuseboard might not provide adequate protection against faults, leaving you exposed to fire hazards, electric shocks, or costly damage to equipment.

The Role of RCBOs
RCBOs (Residual Current Breaker with Overcurrent protection) combine the functions of an MCB (Miniature Circuit Breaker) and an RCD (Residual Current Device) in one unit.
• Shock protection – RCBOs trip when they detect leakage current (such as when electricity is flowing somewhere it shouldn’t, like through a person).
• Overload and fault protection – They also protect against short circuits and overloaded circuits.
• Individual circuit safety – Because each RCBO protects a single circuit, a fault on one circuit won’t cut the power to the whole property. This means more convenience and better overall protection.
In short, RCBOs provide tailored safety for every circuit, making them the gold standard for modern consumer units.

Why SPDs Are Essential
Surge Protection Devices (SPDs) are another critical upgrade. They protect your electrical installation and sensitive electronic devices against voltage spikes, which can be caused by lightning strikes, power cuts, or issues on the grid.
• Protect appliances – Prevents damage to expensive electronics like TVs, computers, and smart home equipment.
• Reduce fire risks – Voltage surges can cause overheating or damage inside electrical equipment, which may lead to fire if unprotected.
• Peace of mind – With more of our lives relying on technology, SPDs help ensure that your equipment stays safe and functional.
Why You Shouldn’t Put It Off
If your property still has an old fuseboard with rewirable fuses or lacks modern protection devices, it’s not just outdated—it could be unsafe. Upgrading to a modern consumer unit with RCBOs and SPDs ensures your installation meets current wiring regulations (BS 7671 in the UK) and gives you the highest level of protection available today.
Final Thoughts
Think of your fuseboard like the engine management system of your home. You wouldn’t ignore a faulty brake system in your car—so don’t ignore outdated electrical protection. Keeping your fuseboard up to date is one of the most important steps you can take to safeguard your home, your loved ones, and your possessions
