Ensure Your Electrical System Is Safe, Compliant & Future-Ready
An outdated or overloaded consumer unit can pose a serious safety risk. Older fuseboards often lack modern protection such as RCDs, increasing the risk of electric shock, electrical fires, and system failure. Electrical Safety First recommends upgrading consumer units where installations no longer meet current safety standards or fail to provide adequate protection.
Regular inspections and timely upgrades help ensure your South London property remains safe, compliant, and insurable.
What Is a Consumer Unit?
A consumer unit, historically referred to as a fuseboard, is the central control point of your electrical installation. It distributes electricity throughout your property and contains essential safety devices, including:
MCBs (Miniature Circuit Breakers) to protect against overloads and short circuits
RCDs (Residual Current Devices) to reduce the risk of electric shock
RCBOs for enhanced individual circuit protection in modern installations
Modern consumer units are designed to disconnect power quickly during a fault, in line with Electrical Safety First recommendations, significantly reducing the risk of injury or fire.
Signs Your Consumer Unit Needs Upgrading
You may require a consumer unit upgrade or replacement if you experience any of the following:
Age of the Installation
Consumer units over 30–40 years old are unlikely to comply with current BS 7671 regulations and often lack essential RCD protection recommended by Electrical Safety First.
Visible Damage or Deterioration
Signs such as burn marks, corrosion, loose connections, or overheating indicate a potential safety hazard and should be addressed immediately by a qualified electrician.
Increased Electrical Demand
Modern households and workplaces place greater demands on electrical systems. Additional appliances, extensions, electric showers, or EV chargers may require a higher-capacity consumer unit.
Compliance Requirements
Consumer unit upgrades are often necessary during property renovations, changes of use, or electrical alterations to maintain regulatory compliance.
EICR Recommendations
An Electrical Installation Condition Report (EICR) may highlight your consumer unit as C1 or C2, meaning urgent or recommended remedial work is required.
