A Domestic Electrical Installation Certificate (EIC) is a
crucial document issued after the completion of electrical installation work in
a domestic property. It certifies that the work has been carried out in
accordance with the current standards, specifically the IET Wiring Regulations
(BS 7671). Here’s a comprehensive overview of what a Domestic Electrical
Installation Certificate entails, its importance, and when it is required.
