Domestic electrical project

Upgrading home safety and functionality in Bookham

This domestic electrical project in Bookham, Surrey, demonstrates the expertise and commitment to quality that define The Big Green Electrical Company. Our NICEIC electricians were approached by a homeowner seeking a safe, future-ready electrical installation to replace outdated circuits and improve everyday convenience. The solution required a full consumer unit upgrade, comprehensive domestic rewire, modern surge protection installation, and enhanced fire safety.

Upon inspection, our electricians identified several key challenges. The property featured two ageing consumer units, with critical circuits powering sockets, lighting, and the boiler in need of modernisation. Our experienced two-person team developed a clear plan to deliver a safe, compliant, and efficient new system with minimal disruption.

  • Replace two consumer units with a single, modern 21-way metal consumer unit.
  • Update socket and lighting circuits throughout the home.
  • Add a dedicated radial circuit for the boiler to enhance reliability.
  • Conceal visible cabling for a tidy finish.
  • Install surge protection and upgraded fire safety measures.

Our solution

A comprehensive electrical upgrade

Our NICEIC-certified electricians in Surrey carried out the full electrical upgrade over six working days. The work began with the removal of the old consumer units and the installation of a new 21-way metal-clad board complete with integrated surge protection. This surge protection installation is vital for safeguarding modern homes that have smart appliances, home entertainment systems, and other sensitive electronics from potential power surges.

Following the consumer unit upgrade, our team undertook a comprehensive domestic rewire of all key circuits. This included installing seven new double sockets in the lounge and additional sockets in the hallways and three bedrooms to provide safe, convenient access to power. We also rewired all lighting circuits, fitting new ceiling lights, dimmer switches, and energy-efficient LED downlights in the bathroom.

Enhancing safety and reliability

Dedicated circuits and fire protection

To ensure consistent and protected power for the home's heating system, we installed a dedicated 2.5mm radial circuit directly to the boiler. This isolates the boiler from other circuits, enhancing its reliability and safety. A key part of the project was also improving the property's fire safety measures. We upgraded the smoke detection system with RF bases and optical smoke alarms, providing improved coverage and peace of mind for the homeowner.

Throughout the installation, our team prioritised a neat and professional finish. All necessary channelling and making good was completed with care. We also made arrangements to fully conceal the Sky cable once the client's decorating works are completed, ensuring a seamless integration of the new electrical system into the home's aesthetic.

Project results

The property now features a single, surge-protected distribution board that meets current electrical standards, offering the homeowner complete peace of mind. The upgraded sockets and lighting circuits have significantly increased safety and usability, reducing the need for trailing leads and extension cables. All work was completed by our trained, NICEIC electrician team, who ensured neat cabling and minimal disruption. Finally, the installation of advanced smoke alarms has enhanced fire detection and coverage throughout the home.
