Upgrading Your Fuseboard: Ensuring Electrical Safety and Compliance with British Standards

Updated: Aug 11, 2023


In our ever-evolving technological landscape, it is essential to prioritize electrical safety within our homes and workplaces. One key aspect of achieving this is upgrading your fuseboard to meet current British standards. By embracing the advancements in electrical technology and incorporating additional protection measures such as RCBOs, SPD devices, and considering the installation of AFDD devices in specific areas, you can ensure a safe and compliant electrical system. In this blog, we will explore the importance of upgrading your fuseboard to align with British standards, the benefits of incorporating protective devices, and the significance of complying with regulations such as BS7671:2018+A2.

Embracing British Standards and Compliance:

BS7671:2018+A2, commonly known as the Wiring Regulations, serves as a comprehensive guide for electrical installations in the UK. By upgrading your fuseboard to meet these standards, you are adhering to the latest safety requirements and ensuring that your electrical system is designed, installed, and maintained in a safe and compliant manner. This not only provides peace of mind but also demonstrates your commitment to electrical safety.

Enhanced Protection with RCBOs:

Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) offer advanced circuit protection by combining the functions of residual current devices (RCDs) and miniature circuit breakers (MCBs). Installing RCBOs during your fuseboard upgrade provides individual circuit protection, reducing the risk of electric shocks and overcurrent situations. By complying with British standards and incorporating RCBOs, you significantly enhance the safety and reliability of your electrical system.

Safeguarding Against Transient Overvoltages with SPD Devices:

Transient overvoltages, such as power surges caused by lightning strikes or sudden electrical disturbances, can pose a threat to sensitive electronic devices. Surge Protection Devices (SPDs) play a vital role in safeguarding your electrical installations against these voltage fluctuations. By incorporating SPD devices in your upgraded fuseboard, in accordance with BS7671:2018+A2, you redirect excess voltage to the ground, protecting valuable equipment and minimizing the risk of electrical fires. This additional layer of protection ensures the longevity and reliability of your electrical system.

Mitigating Arc Faults with AFDD Devices:

Arc faults, which occur when electric current deviates from its intended path, can lead to electrical fires. While not yet a legal requirement in the UK, Arc Fault Detection Devices (AFDDs) are gaining recognition for their ability to detect and prevent arc faults. By considering the installation of AFDD devices, particularly in areas prone to arc faults, you add an extra layer of protection against potential fire hazards. Embracing this emerging technology showcases your commitment to electrical safety and positions your property for future compliance.


Upgrading your fuseboard to meet current British standards, in accordance with regulations such as BS7671:2018+A2, is a crucial step in ensuring electrical safety and compliance. By incorporating protective devices such as RCBOs and SPD devices, you enhance circuit protection and safeguard against transient overvoltages, respectively. Additionally, considering the installation of AFDD devices in specific areas offers further protection against arc faults, reducing the risk of electrical fires.

Investing in an upgraded fuseboard not only promotes a safer living or working environment but also demonstrates your commitment to maintaining a high standard of electrical installations. By aligning with British standards, you prioritize the safety and well-being of your property and its occupants.

Remember to engage a qualified electrician with expertise in British regulations to perform the fuseboard upgrade and installation of protective devices. Their knowledge and experience will ensure that the work is done safely, certified, and compliant with the necessary guidelines.
