A distribution board, a consumer unit, or fuse board, is the central component of your electrical system. It’s responsible for distributing power safely to various circuits throughout your home or commercial property. Modern consumer units are equipped with RCDS (Residual Current Devices) and MCBS (Miniature Circuit Breakers) to protect against electrical overloads, short circuits, and the risk of fire or electric shock.
Fuse board upgrades are typically completed within 3 to 5 hours, depending on the complexity of your installation. Our electricians work cleanly and efficiently to minimise disruption, and we always restore power as quickly as possible. If needed, we can schedule work outside normal hours to avoid affecting your business or home routine.
Yes – once we’ve installed and tested your new consumer unit, you’ll receive an Electrical Installation Certificate (EIC). This certificate confirms that the work has been completed to current regulations and can be used for insurance, landlord compliance, or future property sales.
Absolutely. All of our engineers are NICEIC-certified, fully insured, and highly experienced with all types of distribution boards – from domestic setups to large commercial installations. We follow the 18th Edition Wiring Regulations (BS 7671) to ensure your upgrade is both safe and fully compliant.
