What the electrical installation certificate (eic) actually covers
New circuits, consumer unit replacements and rewires are certified with an Electrical Installation Certificate rather than a condition report. The EIC records the design, construction, inspection and testing of the work and carries the installer's declaration against each.
In every case: part P of the Building Regulations covers domestic electrical work in Wales. Certain work is notifiable to building control, which a registered installer can self-certify rather than routing through a separate application.
