If your fuse box is outdated, unsafe, or simply no longer compliant with modern electrical standards, 2025 may be the right time to upgrade. Replacing a fuse box—now known as a consumer unit—is an essential step toward ensuring your home meets current electrical safety regulations. At RCD Electrical, we deliver professional, NICEIC-certified fuse box replacements across London, ensuring your property remains secure, efficient, and legally compliant.
Why Replace a Fuse Box in 2025?
Fuse boxes installed before the 1990s often lack Residual Current Devices (RCDs), Miniature Circuit Breakers (MCBs), and modern protection systems required by BS 7671 (the UK Wiring Regulations). Older units can pose serious fire and electric shock risks.
In 2025, more landlords and homeowners are choosing to upgrade their consumer units to improve safety, meet legal obligations, and pass EICR inspections. With rising awareness around energy use and home safety, the demand for modern electrical distribution boards is higher than ever.
What’s Included in a Fuse Box Replacement?
A proper consumer unit replacement includes:
-
Removal of the old fuse box
-
Installation of a 17th or 18th Edition compliant consumer unit
-
RCD and MCB protection for all circuits
-
Earthing and bonding checks
-
Testing of all connected circuits
-
Issuing a certificate of compliance
Every job RCD Electrical undertakes is carried out by fully qualified electricians, registered with NICEIC, and fully insured.
