Consumer Unit Upgrades & Fuse Board Replacement in London
Your consumer unit is the heart of your electrical system. If yours is outdated, it cannot protect your home from electrical faults that cause fires and electric shocks. Upgrading to a modern consumer unit with RCD protection is one of the most important safety improvements you can make.

Do You Need a Consumer Unit Upgrade?
You should upgrade your consumer unit if it has rewirable fuses instead of MCBs, no RCD protection, a wooden or plastic enclosure (current regulations require metal), or if it trips frequently. Many London properties built before 2000 have consumer units that no longer meet safety standards.

Every installation includes dual RCD or RCBO protection for all circuits, a metal enclosure to current regulations, full testing of all existing circuits, a Minor Works or Installation Certificate, and Part P Building Control notification.
