Every replacement consumer unit installation starts with a full electrical assessment. We check circuits, cable condition, earthing, bonding, and load distribution to select the right setup for the property.
The old fuse box consumer unit is safely removed, and a metal unit that meets BSI 18th edition consumer unit standards is installed. This may include an RCBO consumer unit, RCD consumer unit, or a unit with SPD for extra protection. All work is completed by NICEIC or NAPIT registered electricians following Electrical Safety First guidance.
For better electrical safety, many homes install smoke and heat alarms during consumer unit upgrades. Choosing the right local electrician consumer unit specialist ensures safe installation, compliance, and reliable performance.
Our domestic consumer unit installation UK follows Part P regulations. Before powering the system, we test earth fault loop impedance, RCD or RCBO trip times, polarity, and insulation resistance to avoid issues from rushed fuse box replacement work.
For improved electrical safety, many properties also install smoke and heat alarms during consumer unit upgrades.
Our domestic consumer unit installation UK service covers houses, flats, and rental properties requiring full electrical panel upgrade UK solutions. We coordinate safe isolation, board replacement, protective device configuration, and compliance testing under one controlled process.
Installations include metal consumer unit systems with RCBO-protected circuits, MCB consumer unit options for structured layouts, and consumer unit with spd configurations for surge resilience. Every installation is labelled clearly for future maintenance and inspection.
Renovation and extension projects often require upgraded consumer units UK compliance. When kitchens, bathrooms, or additional circuits are installed, the board must safely accommodate increased load demand.
Our team assesses whether a replacement consumer unit is required during renovation works and ensures full integration with new wiring installations.
Where properties contain outdated fuse systems lacking RCD protection, we complete full metal fuse board upgrade projects. This includes removal of legacy boards, installation of a new consumer unit with rcbo protection, surge protection device integration, and full safety verification.
All installations are certified and documented to confirm compliance with BSI standards and 18th edition wiring regulations.
Each project begins with identifying signs consumer unit needs replacing. Common issues include overheating, absence of RCD protection, outdated fuse wire carriers, or insufficient circuit separation.
Includes:
Electrical safety inspection, Load calculation & circuit review, Safe isolation & removal, Inspection of bonding & earthing, Pre-installation verification
The new board is installed and configured according to modern regulations. Circuits are distributed logically, and protective devices are assigned per load requirement.
Includes:
Metal consumer unit fitting, RCBO/RCD configuration, SPD installation, MCB allocation, Circuit labelling, Compliance testing
All circuits undergo comprehensive testing before final energisation. Certification confirms compliance with UK electrical standards and may include an EICR certification to verify the safety of the electrical installation.
Includes:
Continuity testing, Insulation resistance testing, RCD/RCBO trip verification, EICR documentation, Part P certification, Final inspection & handover
Site visit and scope assessment
Transparent costs and timelines
Trades coordinated and managed
Snagging cleared, project closed
A consumer unit (also known as a fuse box) is the heart of your home’s electrical system, distributing power to all circuits. It may need replacing if it is outdated, frequently tripping, making buzzing noises, or showing signs of burning smells. Older wooden-backed or plastic fuse boxes no longer meet current UK safety standards. Upgrading to a modern metal-clad unit ensures compliance with BS7671:2018 regulations and significantly improves protection against fire and electric shock.
The typical cost ranges between £375 and £1,200 depending on the size of the property and number of circuits. Most homeowners pay around £485–£650, which includes all parts, labour, and certification. Additional factors such as older wiring or moving the unit to a new location can increase the price. We provide free, transparent quotes with no hidden charges.
No, consumer unit replacement is classified as notifiable work under Part P of the UK Building Regulations. It must be carried out by a qualified, Part P-registered electrician who can issue the required Electrical Installation Certificate upon completion. Attempting this work yourself is illegal and extremely dangerous. Always hire a certified professional to ensure the work is safe and compliant.
In most cases, a consumer unit replacement takes between two to four hours to complete. During this time, the power supply to your property will need to be switched off. Our electricians work efficiently to minimise disruption and restore power as quickly as possible. For larger properties with more circuits, the job may take slightly longer.
Modern consumer units include Miniature Circuit Breakers (MCBs) and Residual Current Devices (RCDs) for superior protection. RCDs detect earth leakage faults and disconnect power within milliseconds, greatly reducing the risk of electric shock or fire. Many modern units also include RCBOs, which offer individual circuit protection for even greater safety. These are a significant improvement over old rewireable fuse wire systems.
Yes, upon completion of the work, your electrician must issue an Electrical Installation Certificate (EIC) to confirm the installation meets UK safety standards. This certificate is an important legal document and will be required when selling your property. Some properties may also require an Electrical Installation Condition Report (EICR) before the replacement begins. We handle all certification as part of our consumer unit replacement service.
