Upgrading an old fuse box prevents overloads and brings modern safety devices into service. - **Upgrading dated fuse boards:** Older fuse boards with rewirable fuses or wooden backs struggle with the demands of modern appliances. Properties such as Victorian cottages around East Hill in Wandsworth benefit from modern units that shut off power instantly if a fault develops. - **Safety in flats and conversions:** In converted period houses across Clapham and Chelsea, electrical intake points are often tucked away in communal hallways or tight cupboards. Installing an updated consumer unit ensures individual circuits isolate cleanly without cutting power to the whole building. ## What happens on the day A standard consumer unit replacement requires the electrical power to be turned off for several hours while the board is changed and all circuits are tested. - **Clearing space around the board:** Please ensure clear access to the existing fuse board, electricity meter and service cut out before arrival. Moving stored coats, boxes or furniture allows testing and installation to proceed without delay. - **Planning for power downtime:** Power will be switched off during the installation. Please charge mobile phones and ensure sensitive computer equipment or heating controls are shut down safely in advance. ## How booking works 1. **Tell us about the job:** Tap Book Now and describe the work in the chat.

Most domestic replacements take between four and six hours depending on the number of circuits. We keep power interruptions limited to the installation and testing period. ### Why do older fuse boards need replacing? Old fuse boxes with cast iron or wooden casings and rewirable fuses lack sensitive earth leakage protection. Modern consumer units disconnect power in milliseconds if a fault occurs, reducing risk to people and appliances. ### Do you need to turn off the power during the replacement? Yes, mains power must be isolated throughout the removal of the old board and the connection of the new unit. Power is restored once initial safety checks are complete. ### What happens if an existing circuit has a fault? We test every circuit before and after energising the new board. If an underlying cable fault causes a modern switch to trip, we explain the issue and discuss the necessary remedial steps with you. ## Business facts - Service area: Colliers Wood, Tooting, Streatham, Balham, Wandsworth, Putney, Battersea, Clapham, Oval, Brixton, Vauxhall, Pimlico, Chelsea, South Kensington, Mayfaair, Fulham - Hours: Calls answered 24/7 - Phone: +447455213345 - Email: info@belloelectricsltd.co.uk - Insurance: Public liability £5M, Professional indemnity £1M - Qualifications: BS7671; Testing and inspection; Initial verification; EV charging; PAT Test ## Book or ask a question - [Book Now](https://belloelectricsltd.co.uk/#chat) ## Related services - [EV charger installation](https://belloelectricsltd.co.uk/services/ev-charger-installation) - [PAT testing](https://belloelectricsltd.co.uk/services/pat-testing)
