Upgrade your old fuse box to a modern consumer unit with RCD protection and 18th Edition compliance
Your consumer unit (fuse box) is the heart of your home's electrical system. If it's outdated or faulty, it could put your family at risk and invalidate your home insurance.
Modern consumer units provide essential RCD (Residual Current Device) protection that can save lives by cutting power in milliseconds if a fault is detected. If your property still has an old-style fuse box with rewirable fuses or lacks RCD protection, it's time for an upgrade to meet current 18th Edition wiring regulations.
Our NICEIC-certified electricians can replace your consumer unit in just a few hours, typically completing the work in a single day. We'll ensure your new unit meets all current safety standards, provide full certification, and notify building control on your behalf.
A clear, step-by-step approach to ensure quality results
We inspect your existing consumer unit and electrical system to determine the best replacement option and identify any additional work needed.

If your property has an old fuse box with rewirable fuses, lacks RCD protection, or is over 25 years old, you should upgrade. It's also required when selling a property or for insurance purposes.
An RCD protects multiple circuits, while RCBOs provide individual protection for each circuit. RCBOs are better as a fault on one circuit won't affect others, preventing nuisance tripping.
