our home’s electrical system is like its nervous system—it powers everything from your kitchen appliances to your Wi-Fi router. And at the center of that system is the fuseboard (also known as a consumer unit or fuse box). If your fuseboard is outdated, it could be putting your safety, energy efficiency, and even property value at risk.
In this blog, we’ll explore what a fuseboard upgrade involves, how to know if you need one, and the benefits of making the switch.
What Is a Fuseboard?
A fuseboard is the main distribution point for electricity in your home. It contains fuses or circuit breakers that control and protect the various circuits in your electrical system. Older fuseboards typically use wire or cartridge fuses, while modern consumer units use miniature circuit breakers (MCBs) and residual current devices (RCDs) for improved safety and ease of use.
Signs You May Need a Fuseboard Upgrade
- Your fuseboard still uses fuses instead of breakers.
Fuses are outdated and can be inconvenient—not to mention less safe—compared to modern breakers. - No RCD protection.
RCDs (residual current devices) are designed to protect against electric shock. If your system lacks RCDs, you could be at greater risk. - Frequent tripping or blown fuses.
If your fuseboard struggles to keep up with your energy demands, it’s a sign that an upgrade may be overdue. - You’re renovating or adding new appliances.
Modern appliances require more power. If you’re upgrading your kitchen or adding a home office, your existing fuseboard might not be sufficient. - Your fuseboard looks damaged or worn.
Burn marks, strange smells, or buzzing sounds are all red flags.
Benefits of Upgrading Your Fuseboard
- Improved safety: New consumer units come with RCDs and MCBs that reduce the risk of fire and electric shock.
- Compliance with regulations: An updated fuseboard ensures your home meets current electrical safety standards.
- Peace of mind: You’ll know your family is protected from hidden electrical faults.
- Increased property value: An upgraded fuseboard is attractive to prospective buyers and can speed up the sales process.
- Future-proofing: You’ll be ready to support electric vehicle chargers, solar panels, and other modern technologies.
What’s Involved in an Upgrade?
A qualified electrician will:
- Inspect your existing electrical system
- Replace the old fuseboard with a modern consumer unit
- Test and certify the installation
- Provide you with a certificate of compliance (usually an Electrical Installation Certificate)
Fuseboard upgrades typically take around a day and can cost anywhere from £400 to £700+, depending on the complexity of your system and local rates.
Final Thoughts
Upgrading your fuseboard isn’t just a technical improvement—it’s an investment in your home’s safety and functionality. If your system is outdated or struggling to keep up, now is the time to consider a professional assessment.
