Fuse board upgrade specialists in SW4
Prestige Engineers provide fuse board upgrades and full consumer unit replacements throughout the SW4 postcode (Clapham) and all surrounding areas. Whether your insurer is requiring an upgrade, you need an EV charger, are adding solar panels, or your property has an old rewirable fuse board, our NICEIC registered electricians handle everything from initial assessment through to the Electrical Installation Certificate.
Properties across the SW4 area that were built or last rewired before 2000 are likely to have a fuse board that cannot provide the RCD protection required by current wiring regulations (BS 7671:2018). Old rewirable fuse boards have no earth leakage protection — a fault in any connected appliance can deliver a potentially fatal electric shock without tripping the supply. Modern dual RCD or RCBO consumer units detect leakage currents as small as 30mA and disconnect within 40 milliseconds.
EV charger installation is driving a significant number of fuse board upgrades across the SW4 postcode. A 7kW home EV charger draws approximately 32A — more than a cooker hob run continuously. We assess your incoming supply at your SW4 property, calculate total connected load, and size the new consumer unit to handle the EV charger circuit alongside all existing circuits, with room for future additions.
Solar panel installations in SW4 also require consumer unit modifications. The inverter needs a dedicated circuit with generation meter and export protection, and many older boards cannot accommodate this. We coordinate with solar installers and handle the DNO application paperwork as needed.
All consumer unit replacement work in the SW4 postcode is Part P notifiable under the Building Regulations. As an NICEIC approved contractor, we self-certify the installation and notify your local authority on your behalf — no separate building control application needed. The Electrical Installation Certificate we issue on the day is the proof your insurer, mortgage lender, and future conveyancer will require.
What we do
Fuse board upgrade services
Consumer unit replacement
Full swap of your old fuse board for a modern dual RCD or RCBO consumer unit — compliant with BS 7671:2018 and Part P of the Building Regulations.
RCD protection
Residual current devices protect against electric shock and fire. Modern boards provide split-load or full RCBO protection on every circuit.
MCB circuit breakers
Miniature circuit breakers replace old rewirable fuses — they trip instantly on overload and reset with a switch rather than requiring fuse wire replacement.
Surge protection device
SPD installation protects sensitive electronics (smart TVs, computers, appliances) from voltage spikes caused by lightning or grid switching.
EV charger preparation
Installing a home EV charger requires a dedicated circuit and often a board upgrade. We size the new consumer unit with capacity for your charger from day one.
New circuit addition
Adding an extension, outbuilding, garden office or kitchen rewire? We add dedicated circuits to the new board with correct protection for each load.
