The Approved Contractor will check the electrical installation against the requirements of BS7671 – Requirements for Electrical Installations ( IEE Wiring Regulations) – as amended, which is the national safety standard for electrical installations, and contains around 850 Regulations.
The Periodic Inspection will take into account all relevant circumstances including the following factors:
> Adequacy of earthing and bonding.
> Suitability of the switchgear and controlgear e.g. consumer unit e.g. an old fusebox with a wooden back, cast iron switches, a haphazard mixture of such equipment is likely to need replacing.
> Serviceability of equipment e.g. switches, socket-outlets and light fittings e.g. older round pin sockets, round light switches and braided flex hanging from ceiling roses to light fittings, black switches, sockets mounted in skirting boards may require replacing.
> Type of wiring system and its condition e.g. cables coated in black- rubber, black-rubber was phased out in the 1960s or cables coated in lead or fabric are even older and may need replacing (modern cables use pvc insulation).
> Provision of residual current devices for socket-outlets that may be used to plug in electrical equipment used outdoors.
> Presence of adequate identification and notices.
> Extent of any wear and tear, damage or other deterioration.
> Changes in use of the premises which have led to, or might lead to, deficiencies in the installation.
The Approved Contractor will provide a periodic inspection report (PIR) as part of the periodic inspection.
