Full circuit testing included. If your property has an outdated fuse box requiring modern circuit protection, MX2 Electrical provides complete consumer unit and fuse board replacements. Our NAPIT registered electricians mount new metal boards, dress every circuit and fit surge protection across Poole, Bournemouth and Broadstone. Each circuit is thoroughly tested before and after installation to keep your electrical setup safe. ## Fuse board replacement price Upfront pricing for replacing an existing residential consumer unit. Final quotations depend on the number of circuits, existing earthing arrangements and any required remedial repairs. - Consumer unit and fuse board replacement: £500 - Covers the supply and installation of a standard domestic metal consumer unit with dual RCD or RCBO protection. - Includes full testing of connected circuits and issue of an Electrical Installation Certificate. - Excludes repairing pre-existing circuit faults discovered during initial testing or rewiring damaged cables. - Excludes upgrading the main incoming supply tails or main protective earthing conductors if undersized. ## Check whether replacement is right Modern electrical demands and safety regulations make upgrading an obsolete fuse board an important safety improvement for domestic properties. - **Rewireable fuses and wooden boards:** Older properties in Wimborne Minster, Wareham and Westbourne often still contain wooden-backed fuse boards with rewireable carriers. These offer no residual current protection against electric shocks or electrical fires. - **Missing RCD protection:** Twentieth-century homes in Broadstone, Canford Heath and Ferndown may have early cartridge fuse boxes or basic miniature circuit breakers without RCD switches. Modern standards require RCD protection across socket and lighting circuits. - **Renovations and added circuits:** Adding new circuits for kitchen extensions, heat pumps or electric vehicle chargers in Bournemouth and Poole requires spare capacity and modern protective devices that older consumer units cannot support. ## What the replacement covers Our standard replacement service covers the physical unit swap, testing and statutory certification. ### Included when agreed - Isolation of the electrical supply and removal of the old fuse board - Installation of a metal consumer unit compliant with current wiring regulations - Fitting of individual circuit protection devices including RCDs and circuit breakers - Inspection and testing of all connected final circuits - Issue of a Building Regulations compliance certificate via NAPIT - Supply of an Electrical Installation Certificate recording all test values ### Not included automatically - Rectification of pre-existing faults on existing household wiring - Upgrading supplier equipment, meter tails or main service cut-out fuses - Plastering, painting or decorating work around the new board location ## How the job works Replacing a consumer unit requires turning off the power and carrying out structured safety checks across the property. 1. **Preparation and pre-installation tests:** Clear the area around the existing fuse board and meter. We perform initial continuity and insulation resistance tests on connected circuits before isolating power to identify pre-existing faults. 2. **Board installation:** Power to the property will be turned off while the old unit is disconnected and removed. We mount the new metal enclosure, connect the incoming supply tails and terminate each circuit into its dedicated breaker. 3. **Testing and energisation:** Once wired, power is restored step by step. We carry out full instrumental testing on every circuit, checking trip times, earthing loop impedance and polarity to confirm safe operation. ## What you receive Following the installation, you receive full documentation certifying that your new consumer unit complies with electrical safety regulations. - **Replacement board:** A fully labelled metal consumer unit fitted with modern protective devices suited to your installation, such as residual current devices and miniature circuit breakers. - **Circuit test results:** A complete schedule of test results documenting insulation resistance, earth fault loop impedance, and disconnection times for every connected circuit in the property. - **Electrical certificate:** An Electrical Installation Certificate confirming the replacement meets BS 7671 wiring standards, accompanied by notification to local building control through NAPIT. - **Clear next steps:** Guidance on how to operate and test the RCD buttons periodically, along with recommendations if any existing circuit wiring requires future attention. ## Fuse board questions Common questions about replacing domestic fuse boards and upgrading to modern consumer units. ### How long will my power be turned off during the replacement? I turn off the electricity supply once pre-testing is complete. The power remains off while I remove the old board, mount the new unit and terminate the circuits. I keep you informed during the outage and restore supply as soon as it is safe to test. ### What happens if you find a fault with my existing wiring? I test your existing circuits before fitting the new board. If I uncover an underlying fault, such as damaged insulation or a bridged neutral, I will explain the issue clearly and discuss what is needed to resolve it before the circuit is re-energised. ### Why do old fuse boards need replacing? Older fuse boards with wire fuses or early breakers cannot detect minor earth leakages quickly enough to prevent electric shocks. Modern units disconnect faulty circuits in milliseconds and use non-combustible metal enclosures. ### Do I need to notify building control when changing a fuse board? Replacing a consumer unit is notifiable work under Part P of the Building Regulations. Because MX2 Electrical is NAPIT registered, we notify building control directly and provide your compliance certificate. ### What space is needed around the new consumer unit? The new board must be accessible for maintenance, operation and testing. It should be mounted securely on a flat surface with sufficient clearance from gas meters and sources of heat or moisture. ## Trusted consumer unit guidance Official guidance and standards relating to domestic consumer unit replacements and building safety regulations. - [Replacing a consumer unit](https://www.electricalsafetyfirst.org.uk/media/uetp0drg/best-practice-guide-1-issue-5.pdf): Official best practice guidance covering technical requirements and safety checks when replacing a domestic consumer unit. - [Building work and electrical safety](https://www.gov.uk/government/publications/building-work-replacements-and-repairs-to-your-home/building-work-replacements-and-repairs-to-your-home): Government guidance on Part P building regulations and safety notification duties for domestic electrical work. ## Business facts - Based: Aldhelms Road, Poole, BH12 1AE - Service area: Poole, Bournemouth, Broadstone, Wimborne Minster, Wareham, Parkstone, Ferndown, Christchurch, Canford Heath, Westbourne - Hours: Every day 00:00–23:59 - Phone: +447397844504 - Email: info@mx2-electrical-ltd.co.uk - Insurance: Public liability £2,000,000 - Qualifications: Nvq level 3, City&Guilds; Gold Card Electrician - Pricing rules: Current labour rate: £70 per hour.; Materials, specialist equipment and larger project work are confirmed separately before they go ahead. ## Request a quote - [Start a request](https://mx2-electrical-ltd.co.uk/#chat): Send the job details and postcode to MX2 Electrical. ## Related pages - [EICR](https://mx2-electrical-ltd.co.uk/services/eicr): EICR testing and electrical safety reports. - [House Rewiring](https://mx2-electrical-ltd.co.uk/services/house-rewiring): Full and partial house rewiring. - [Electrical Fault Finding & Repair](https://mx2-electrical-ltd.co.uk/services/electrical-fault-finding): Find and repair electrical faults. - [EV charger installation](https://mx2-electrical-ltd.co.uk/services/ev-charger-installation): Home and workplace EV charger installation. - [Electric Shower Installation](https://mx2-electrical-ltd.co.uk/services/electric-shower-installation): Electric shower installation and replacement. - [Full sitemap](https://mx2-electrical-ltd.co.uk/sitemap.md): Complete machine-readable page directory.
