Where Do I start?
Electrical safety begins with awareness and ends with action. Your consumer unit—often tucked away and forgotten—plays a vital role in protecting your family, property, and modern lifestyle. From outdated fuse boards with rewireable fuses to units lacking essential RCD protection, hidden risks can go unnoticed for years. Now is the time to act before warning signs like frequent tripping, scorch marks, or warm switch plates escalate into serious dangers.
Start by scheduling a professional Electrical Installation Condition Report (EICR) to evaluate your system’s integrity. This inspection reveals non-compliant components, degraded wiring, and potential hazards—especially critical in homes over 25 years old or those in Wigan and Greater Manchester with legacy electrical setups. Upgrading isn’t just about meeting current BS 7671 regulations; it’s about future-proofing your home for EV chargers, smart devices, and increased electrical demands.
How do I know if my consumer unit needs upgrading?
Look for telltale signs like frequent circuit breaker trips, visible scorch marks, a burning smell near the unit, or an older model with ceramic fuses instead of modern MCBs. Units over 25 years old—common in homes across Wigan and Greater Manchester—often lack RCD protection and may not meet current BS 7671 safety standards, increasing fire and shock risks.
Is upgrading legally required?
While not automatically mandated by law, upgrades are typically needed during property sales, renovations, or new electrical installations (like EV chargers or solar panels). Compliance with Part P of the Building Regulations and the latest IET Wiring Regulations (BS 7671) is essential, and an outdated unit could fail an Electrical Installation Condition Report (EICR).
What’s included in a modern consumer unit?
Today’s units feature RCD or RCBO protection on all circuits, ensuring rapid disconnection during earth faults. This is critical for safety in high-moisture areas like kitchens and bathrooms. Many also support surge protection and smart monitoring integration.
How much does an upgrade cost?
Average costs range from £650 to £1,200, depending on complexity, load requirements, and local labour rates in Northwest England. Larger homes or those needing additional cabling may see higher prices. Always request a detailed quote from a certified electrician.
Can I install it myself?
No. Consumer unit replacement is not a DIY task. It must be completed by a qualified, Part P–registered electrician to ensure compliance, safety, and insurance validity.
How long does installation take?
Most replacements take 6–8 hours in a single day, though larger properties may require additional time. Temporary power shutdown is necessary during the process.
Will I need full re-wiring?
Not necessarily. A new consumer unit can often work with existing wiring if circuits are in good condition. Your electrician will inspect your system during installation to confirm compliance.
