Consumer Unit Upgrades (Fuse Board)

---

Your fuse board—or consumer unit—is the heart of your home’s electrical system. It controls and distributes electricity to every socket, light, and appliance in your property. More importantly, it is your primary line of defense against electrical faults, shocks, and fire hazards.

If your home still relies on an old-fashioned fuse box, it may not meet modern safety standards. At D.Carter Electrical Ltd, we specialize in upgrading outdated consumer units across Norwich, Norfolk, and Suffolk, providing modern, fully compliant replacements that keep your home and family safe.

Electrical regulations are constantly evolving to make homes safer. Modern consumer units feature RCDs (Residual Current Devices) or RCBOs—life-saving trip switches that instantly cut the power if a fault is detected, preventing severe electric shocks and electrical fires.

It is highly recommended that you upgrade if:

• Your board is outdated: It has a wooden back, cast-iron switches, or old rewirable (wire) fuses.
• You lack RCD protection: If your current board doesn't have RCDs, your home does not meet current UK safety standards.
• You are adding new circuits: Planning a new extension, loft conversion, or installing an EV charger, solar panels, or a hot tub often requires a modern, high-capacity board.
• You experience frequent tripping: If your power cuts out regularly or you notice a buzzing sound or burning smell near your fuse box, you need an inspection immediately.                    

Modern homes are packed with sensitive, expensive electronics—from smart TVs and computers to smart home heating systems and kitchen appliances.

Under the latest 18th Edition wiring regulations, we install Surge Protection Devices (SPDs) as a standard part of our consumer unit upgrades. An SPD acts as a shield for your entire house. If there is a power surge—caused by lightning strikes or fluctuations in the national grid—the SPD detects the voltage spike and instantly redirects the excess energy away from your circuits, preventing your valuable electronics from being fried.
