Replacing a fuse board — properly called a consumer unit — is notifiable work under Part P of the Building Regulations. It has to be done by a registered electrician and certified, or notified to Building Control.
What the job actually involves
- Isolating the supply and safely removing the old board.
- Fitting a new metal-clad consumer unit with RCBOs or dual RCDs.
- Re-terminating every circuit and checking main earthing and bonding.
- Full testing and issuing an Electrical Installation Certificate.
Why you shouldn't DIY it
Working next to the incoming supply is genuinely dangerous, and uncertified work can invalidate your home insurance and cause problems when you sell. We handle everything including the paperwork with Building Control.
