Safe, Modern Consumer Units Installed by Qualified Portsmouth Electricians
Your consumer unit is the heart of your home’s electrical system, distributing power to every circuit and providing crucial protection against electrical faults. If your property still has an old fuse board with rewirable fuses, a plastic consumer unit without RCD protection, or a board that simply cannot cope with modern electrical demands, upgrading to a new consumer unit significantly improves your home’s safety.
Modern consumer units feature RCDs that detect earth faults and cut power within milliseconds, dramatically reducing the risk of electric shock and electrical fires. MCBs replace outdated fuses, providing reliable overload protection that can be simply reset rather than requiring fuse wire replacement. Metal enclosures offer fire resistance that older plastic units cannot match. Together, these features provide life-saving protection that older boards were never designed to deliver.
Beyond safety, a new consumer unit supports your home’s current and future electrical needs. Additional circuits for extensions, EV chargers, or home offices can be accommodated properly. Nuisance tripping caused by overloaded or deteriorating old boards is eliminated. Your installation meets current BS 7671 wiring regulations, providing peace of mind and documented compliance that proves valuable when selling your property.
We install and upgrade consumer units across Portsmouth, providing NICEIC certified installations with full testing, documentation, and Building Control notification. Contact us for a free assessment and fixed-price quote.
Every consumer unit replacement begins with a thorough assessment of your existing electrical installation. We inspect your current fuse board, check the condition of your wiring, and identify any issues that need addressing alongside the upgrade. This assessment allows us to provide an accurate, fixed-price quotation with no surprises. We explain what work is required, recommend the appropriate consumer unit specification for your Portsmouth property, and answer any questions you have. Once you are happy to proceed, we schedule the installation at a time that suits you, typically completing most replacements within the same week.
On installation day, we isolate the electricity supply and safely remove your old fuse board. The new metal consumer unit is then fitted in the same location, with all circuits carefully reconnected to the appropriate MCBs and RCDs. We ensure neat, professional cable management throughout. The entire process typically takes four to six hours depending on the number of circuits and any additional work required. We keep disruption to a minimum and work cleanly, protecting your home throughout. Your electricity will be off during installation, so we recommend planning accordingly for the day.
Once installation is complete, we carry out comprehensive testing of every circuit in your home. This includes insulation resistance testing, earth fault loop impedance testing, polarity checks, and RCD trip time testing to verify your new consumer unit provides the protection it should. All test results are documented on an Electrical Installation Certificate, your official proof that the work meets BS 7671 wiring regulations. As NICEIC registered electricians, we also notify Building Control on your behalf, ensuring full compliance with legal requirements. You receive all documentation for your records.
Before we leave, we walk you through your new consumer unit, explaining how it works and what to do if a circuit trips. We label every circuit clearly so you can identify which breaker controls which area of your home. You receive your Electrical Installation Certificate and Building Control notification confirmation. Our work is fully guaranteed, and we remain available if you have any questions or concerns after installation. Should any issues arise with your new consumer unit, simply contact us and we will return to resolve them promptly for Portsmouth customers.
