Inspect at first fix (before plasterboard) and second fix (before energisation). Check every back-box, every cable run, and every earth connection. Do not allow walls to be closed until first fix is signed off.
A stage inspection checklist for electrical contractors and building inspectors verifying electrical installation quality at first fix (before walls are closed) and second fix (before energisation). Covers containment and trunking, cable routing and support, back-box installation, earthing and bonding, distribution board installation, RCD protection, circuit identification, and the pre-commissioning visual check before formal testing and certification.
Electrical defects hidden behind walls are impossible to inspect after completion and can cause fires, shocks, and nuisance tripping for the life of the building. First-fix inspection — while cables and containment are visible — is the only opportunity to verify installation quality before it's concealed forever.
