Consumer units, also known as a fusebox or fuseboard, play a vital role in controlling the electrical circuits within your home, while also serving as a crucial safety mechanism to detect any potential dangers.

Ensuring the electrical integrity of your fuseboard is essential for the safety of everyone within your property and for the unit to function effectively in case of a fault.

Modern consumer units are equipped with Residual Current Devices (RCDs), which provide instant fault detection and offer superior protection for your property. Additionally, considering the installation of surge protection and arc fault detection devices within the consumer unit further enhances safety measures.

With various styles and configurations available, we are here to assist you in identifying and addressing your specific requirements.

Some frequently asked questions about Fuseboard Upgrades. If you need any more information please call us on 07950 205246.

A fuseboard upgrade (or consumer unit upgrade) involves replacing your old fusebox with a modern consumer unit that meets current UK electrical safety standards. At Master Spark, we install units equipped with RCDs (Residual Current Devices), MCBs (Miniature Circuit Breakers), and Surge Protection Devices (SPDs) for enhanced protection against electrical faults and power surges. Unlike old fuseboxes, modern consumer units can detect a wider range of faults, such as earth leakage faults, which older systems often miss. This upgrade is essential for improving the safety of your home, reducing the risk of electrical fires, electric shocks, and ensuring compliance with BS 7671 (the latest UK Wiring Regulations). An outdated fusebox can struggle to handle the increased electrical demand of modern appliances, and without surge protection, your electronics are vulnerable to power surges. Upgrading not only improves system reliability and safety, but also ensures better fault detection and protection against electrical surges.

Common signs that your fuseboard needs upgrading include frequently tripping circuits, an old-style fusebox with rewirable fuses, and a lack of RCD protection. If you notice flickering lights, discoloured sockets, or if your fusebox looks outdated (often over 30 years old), it’s a good indication that an upgrade is needed. Additionally, if you’re carrying out home improvements like adding new electrical circuits or appliances, or if you’re selling or renting out your property, upgrading is highly recommended. At Master Spark, we offer Electrical Installation Condition Reports to confirm whether a new consumer unit is required.

Upgrading to a modern fuseboard offers multiple advantages for your home’s electrical system:

  • Improved safety: Modern consumer units are equipped with Residual Current Devices (RCD’s) and Miniature Circuit Breakers (MCB’s), which can detect electrical faults that older fuseboxes cannot, such as earth leakage faults. In the event of a fault, the RCD trips the circuit, significantly reducing the risk of electrical fires, electric shock, and other hazards. This ensures that your home meets the latest BS 7671 safety standards.
  • Surge protection: New fuseboards include Surge Protection Devices (SPD’s), which protect your home from electrical surges caused by lightning strikes or power grid fluctuations. This prevents costly damage to appliances and electronics, which older fuseboxes cannot protect against.
  • Increased efficiency: A modern consumer unit ensures better distribution of electricity throughout your home, optimising the system to handle the higher demand of today’s appliances. This reduces the likelihood of circuits tripping and improves the overall efficiency and performance of your electrical system.
  • Enhanced reliability: Built with higher-quality materials and improved technology, modern consumer units are more robust and less likely to fail compared to outdated fuseboxes. This increased reliability minimises the risk of power outages or overloads, keeping your electrical supply stable and consistent.
  • Easier maintenance: Some modern consumer units are designed with built-in diagnostic features that make it easier to troubleshoot and fix issues when they arise. At Master Spark, we ensure that your new unit is installed with safety and convenience in mind, making maintenance and fault-finding much quicker and more straightforward.

When you choose Master Spark for a fuseboard upgrade, the process starts with an Electrical Installation Condition Report (EICR) to check the safety of your existing electrical system. Once any faults are identified and rectified, we remove the old fusebox and install a new, modern consumer unit. This includes connecting the circuits to RCD’s and MCB’s, which provide enhanced protection. After installation, we perform thorough testing to ensure everything is wired correctly and meets BS 7671 standards. Finally, we issue an Electrical Installation Certificate and notify building control ensuring your system is safe and fully compliant. After installation, we will also provide you with a demonstration of how the new consumer unit operates. This includes showing you how to periodically manually test the RCD (Residual Current Device) to ensure it’s functioning correctly and what steps to take if a circuit happens to trip.

Typically, a fuseboard upgrade takes the best part of a day to complete, but this can vary depending on the size of the property and the number of circuits the fuseboard has. For larger homes or systems with outdated wiring, the process could take a little longer. Once the new consumer unit is installed, we carry out a thorough electrical test on the entire system to ensure all the circuits are functioning correctly, and then provide you with an Electrical Installation Certificate. At Master Spark, we aim to complete the job efficiently while ensuring everything is done to the highest safety standards. Before starting the upgrade, we will provide you with a clear timeframe based on the specific needs of your property, so you know what to expect.

Having an Electrical Installation Condition Report (EICR) carried out before a fuseboard upgrade is essential to assess the current condition of your electrical system. The EICR identifies any existing issues, such as outdated wiring, faulty connections, electrical wiring faults, ensuring that they are addressed before installing the new consumer unit. It also helps to identify faults that may cause the new more modern sensitive circuit breakers to trip, ensuring your new fuseboard operates safely and efficiently. This step is crucial for safety and compliance with the electrical wiring regulations. Without an EICR, you risk potential safety hazards and system inefficiencies that could affect the performance of your new fuseboard.

The cost of a consumer unit (fuseboard) upgrade can vary depending on the number of circuits, the size of property, and the specification of the consumer unit itself. Generally, prices start from around £500.00 + VAT for a smaller fuseboard replacement, which includes materials, labour, and certification. At Master Spark, we offer a free, detailed assessment of your property and provide a transparent quote before any work begins. Our pricing reflects the quality of materials we use and the high level of care and compliance we guarantee in every job.

While a fuseboard upgrade won’t directly lower your energy bills, it can help improve the overall energy efficiency of your home’s electrical system. By upgrading to a modern consumer unit, you reduce the risk of electrical faults and system overloads, which can waste energy and cause potential damage to your appliances. At Master Spark, we ensure your electrical circuits are balanced and functioning properly, which can help protect your appliances and reduce long-term energy costs.

When upgrading your consumer unit, we offer three key options, tailored to your needs:

1.) Dual RCD Consumer Unit: This unit comes with two main RCD’s, each protecting half of the circuits in the property. If a fault occurs in one circuit, the RCD will trip and that results in all the circuits protected by that particular RCD losing power, until the fault is rectified and the RCD restored. This is a reliable and affordable option for most households, and the most common set up at present.

2.) Consumer Unit with Individual RCD Protection (RCBO’s): For enhanced protection, this option features individual RCBOs (Residual Current Breaker with Overcurrent) per circuit. If a fault occurs, only the affected circuit will trip, leaving the rest of your electrical system unaffected. This is ideal for minimising disruption and maximising safety.

3.) Arc Fault Detection Upgrade: This premium option includes Arc Fault Detection Devices (AFDDs), offering the highest level of protection by detecting and preventing electrical arcs that could lead to fires.

At Master Spark, we use only the best manufacturers to ensure reliability and long-term safety for your home. We can advise you on the best option for your property.
