Fuse board upgrades, also known as fuse box or consumer unit upgrades, are an important step in ensuring your home remains safe and energy-efficient. Upgrading your fuse board helps your electrical system meet modern safety standards, improves power distribution, and accommodates the higher electrical demands of today’s appliances and technology.
Older fuse boards were designed to meet safety standards that are now outdated and no longer suitable for modern homes. Electrical regulations are frequently updated to improve safety, reflect new technologies, and reduce the risk of electric shock and fire. As a result, many older fuse boards do not provide the level of protection now required for domestic properties.
Under the 18th Edition IET Wiring Regulations (BS 7671), modern consumer units must include RCD (Residual Current Device) protection on circuits. RCDs are a critical safety feature that continuously monitor the flow of electricity and automatically disconnect the power supply within milliseconds if an earth fault or imbalance is detected. This rapid disconnection significantly reduces the risk of electrocution, serious injury, and electrical fires.
In addition to RCD protection, many modern fuse board upgrades also incorporate RCBOs, which provide both overload and earth-fault protection on individual circuits. This improves safety and reliability by ensuring that a fault on one circuit does not affect the rest of the property.
Upgrading your fuse board ensures your electrical system is fully compliant with current UK regulations, meets the latest safety requirements, and provides peace of mind for homeowners, landlords, and tenants. It is also often a requirement when selling a property, renting it out, or carrying out major electrical or building work.
Upgrading to a modern fuse board improves electrical safety by introducing advanced protection devices.
RCD Protection
RCDs reduce the risk of electric shock by quickly disconnecting the power supply if a fault is detected. They can protect individual circuits or the entire fuse board.
RCBOs
RCBOs combine RCD and circuit breaker protection, safeguarding against electric shock, overloads, and short circuits while improving reliability.
Surge Protection
Modern fuse boards can include surge protection to help protect appliances from voltage spikes and electrical disturbances.
Modern homes rely on high-power electrical appliances. A fuse board upgrade ensures your system can handle increased loads safely without frequent tripping.
Dedicated Circuits
An upgraded fuse board allows separate circuits for high-power appliances, improving efficiency and preventing overloads.
A modern fuse board provides flexibility to add new circuits for home extensions, smart technology, or additional appliances, ensuring your electrical system can grow with your needs.
Some modern fuse boards include smart technology, allowing you to monitor power usage and control circuits remotely via an app. This makes it easier to track energy consumption and manage your electrical system efficiently.
New fuse boards also feature clear circuit labelling, making it quicker and safer to identify circuits during maintenance or in an emergency.
Upgrading your fuse board replaces worn or outdated components that can degrade over time. This improves system reliability and reduces the risk of electrical faults.
A modern consumer unit also helps prevent frequent tripping, especially when multiple high-power appliances are used at the same time.
A fuse board upgrade must be carried out by a qualified electrician to ensure compliance with current safety regulations. The process includes safety checks, installation of the new consumer unit, and full system testing.
The cost typically ranges from £300 to £1,500, depending on the size of the property and features such as RCDs, RCBOs, and surge protection. After installation, you’ll receive testing and certification, often required for insurance or property sales.
You may need a fuse board upgrade if your system is old or outdated, you experience frequent tripping, or your fuse board lacks RCD protection. Other warning signs include flickering lights, overloaded circuits, or plans to install high-power appliances such as EV chargers or air conditioning.
