Rules & regulations
- Notifiable under Part P, a registered electrician must fit and certify it
- Old fuse-wire boards aren't illegal, but insurers and buyers increasingly expect modern RCD protection
- Testing often uncovers pre-existing faults that must legally be put right before energising
Snap tips
- RCBOs are worth the difference: a faulty kettle no longer blacks out the freezer
- Budget headroom, the testing stage finds problems the quote couldn't see
