​

Your consumer unit, often known as a fuse board, is the heart of your electrical system. It distributes power around your property and protects your home from potential electrical faults. If yours is old, overloaded or not compliant with the latest safety regulations, it could put your property at risk.

At BSJ Electrical, we provide professional consumer unit upgrades in Chelmsford, Essex, Hertfordshire and London. Our qualified electricians replace outdated fuse boards with modern, safe and efficient consumer units that meet current wiring regulations (18th Edition BS 7671).

​

Why Upgrade Your Consumer Unit?
 

Many older properties still have fuse boards fitted with re-wireable fuses or outdated components. These may not provide adequate protection against modern-day electrical usage. By upgrading your consumer unit, you benefit from:

• Improved safety – reduces the risk of fire and electrical shock

• Compliance – ensures your property meets current UK wiring regulations

• Better protection – modern units include RCDs and RCBOs to instantly cut off power in case of faults

• Future-ready – supports additional circuits for EV chargers, solar panels and new appliances

• Peace of mind – knowing your home or business is properly protected

​

Signs You May Need a Fuse Board Upgrade
 

• Frequent tripping of circuits or blown fuses

• Burn marks, buzzing noises or smells coming from the consumer unit

• An old fuse board with wooden backing or re-wireable fuses

• Lack of RCD protection

• Adding major new electrical installations, such as an EV charger or solar panels

 

If you’re unsure whether your consumer unit needs upgrading, our electricians can carry out a professional inspection and provide honest advice.
