The way I see it:
Part P Building Regs mandates work is as per Wiring Regs BS7671.
Electrical Installation Certificate (EIC) states that works complies with BS7671. Contains details of installation address, installer, tester, test results etc.

As per Part P of Building Regs, once electrical work is performed by a registered competent person, the installation certificate needs to be given to occupier and also to building control.
