Certified Fuse Box Installation in the UK

This is the current UK standard for electrical installations. It ensures your board includes:
​RCDs: To prevent electrocution.
​MCBs (Miniature Circuit Breakers): To protect your wiring from overloading.
​SPD (Surge Protection Device): Now standard in 2026 to protect your sensitive electronics (TVs, laptops, smart home hubs) from power surges.

While you don’t have to upgrade a board just because the regulations change, it must be safe. If your EICR returns a C1 or C2 code because of an unsafe old fuse box, you are legally required to upgrade it to meet “Satisfactory” standards.

Typically, it takes between 3 to 5 hours. This includes the physical installation and the mandatory safety testing of every circuit in the house afterward.

Yes. The main power will be turned off for the duration of the installation. We recommend scheduling this when you don’t have critical work meetings or sensitive equipment running.

Absolutely. After installation, Certivest London provides:
​An Electrical Installation Certificate (EIC).
​Part P Notification: We notify your local building control (via NICEIC/NAPIT) that the work is compliant. This is vital for when you sell your property.

An Arc Fault Detection Device (AFDD) is a smart breaker that detects “sparking” (arcing) inside walls caused by damaged cables or loose connections. In 2026, these are highly recommended (and sometimes mandatory) for high-risk residential buildings and bedrooms.
