There are 3 types of electrical certificate defined by BS7671:
The Electrical Installation Certificate
This is issued for new installations or major work on existing installations. Also work in Special Locations – which includes rooms with running water (kitchens, bathrooms, swimming pools, etc) and any exterior installation (ponds, garden lights etc).
The Minor Electrical Works Certificate
This is issued for other repairs, replacements or modifications in non-Special Locations.
The Electrical Installation Condition Report
Formerly The Periodic Inspection Report, it is designed to determine whether an electrical installation is in a safe and satisfactory condition for continued service. The inspection comprises a detailed examination of the installation without dismantling (or with partial dismantling as required) supplemented by appropriate tests to provide for:
- the safety of occupants against the effects of electric shock
- protection against damage to property by fire and heat arising from an installation defect
- confirmation that the installation is not damaged or deteriorated so as to impair safety
- the identification of installation defects and departures from the IEE Regulations that may give rise to danger.
This certificate is sometimes (erroneously) known as the Landlord’s Safety Report.
It is recommended that a domestic dwelling is tested every 10 years, and a residential property be tested every 5 years, or upon a change of occupancy.
