Upgrade Your Fuse Box with a Modern Consumer Unit
Replacing an old or outdated fuse box is a crucial step in improving the safety and reliability of your electrical system. Modern consumer units offer greater protection against electrical faults, including built-in RCDs (Residual Current Devices) and circuit breakers designed to cut power quickly in the event of overloads, short circuits, or earth faults. A replacement can significantly reduce the risk of electrical hazards if your current fuse box is outdated, lacks RCD protection, or struggles to keep up with modern power demands.
Upgrading to a modern fuse box ensures your installation complies with the latest electrical regulations (BS 7671) and provides peace of mind that your home or business is protected. Whether you’re renovating, extending a property, or experiencing issues with your existing unit, a replacement can also help future-proof your electrical system for new technologies and appliances. All replacements are completed by qualified electricians, with minimal disruption and full certification provided upon completion.
