Read MoreUpgrading your consumer unit (fuse box) is essential to ensure your home or business meets modern electrical safety standards. At Certified Electricians London Ltd, our experienced electricians specialise in installing and upgrading consumer units, ensuring your property's electrical system is safe, efficient, and compliant with current UK regulations.
Consumer units are critical components of your property’s electrical safety infrastructure. Older fuse boxes may struggle to cope with contemporary electrical demands, increasing risks such as electrical faults or fires. Current regulations, including the 18th Edition of the IET Wiring Regulations (BS 7671), mandate features like RCD protection in consumer units, significantly improving safety. Upgrading ensures your property meets these vital safety standards.
Our consumer unit upgrades typically include essential components such as RCDs (Residual Current Devices) for earth fault protection, MCBs (Miniature Circuit Breakers) to prevent circuit overloads, RCBOs (Residual Current Breakers with Overcurrent) combining multiple protections in one device, and SPDs (Surge Protection Devices) that safeguard your electrical appliances from damaging power surges. Additionally, a main switch is installed, enabling easy power shut-off during emergencies.
At Certified Electricians London Ltd, our electricians are fully qualified and NICEIC-approved, undergoing stringent assessments to uphold the highest safety and technical standards. We ensure all consumer unit installations are performed safely, professionally, and in strict compliance with UK regulations. Trust us to deliver high-quality, reliable consumer unit installations for your property in London, Essex, or Kent.
A consumer unit, otherwise referred to as a fuse board acts as the control centre for a properties electrical system. Different consumer units can be used for different applications depending on the property type and size. A consumer unit usually acts as a first point of contact for querying electrical faults within a home, and its interface reflects this. With most consumer units you will expect to see a mains switch, RCD and switches for circuit breakers corresponding to different parts of the property.
Consumer units can differ depending on the type of property. Units present in commercial properties must consider different use scenarios in addition to safety. Residential/domestic properties require a different set of requirements to detect and remedy faults.
While most faults cannot be diagnosed easily, there are a few important things we can look out for with our consumer units to ensure their safety:
A faulty consumer unit can be a fire hazard, unnecessarily inflate electric bills and interfere with the safe operation of appliances in your home or business.
Consulting a registered electrician is required, work must be completed to the latest safety standards and the task itself requires an understanding of the complex electrical system in your property.
It can be overwhelming to select the correct fuse box for your property with so many options on the market. If you are uncertain and need a helping hand, we have a wealth of experience selecting and installing consumer units in London.
