Just to clarify:

A formal inspection and test of the system is called an EICR - Electrical Installation Condition Report. This is what is needed, and any competent electrician can carry one out. (Formerly known as a PIR - Periodic Inspection Report)

The NICEIC - National Inspection Council for Electrical Installation Contracting is one of a number of organisations who provide oversight and monitoring of Competent Person Schemes. Electricians and electrical businesses can sign up for membership, in which case the NICEIC provide a quality assurance service over the contractor.

There is no need for whoever carries out the EICR to be a member of the NICEIC; they could equally well be members of NAPIT for example, but NICEIC is probably the best known. Note that some work in dwellings is subject to building regulations Part P, which imposes further requirements on the contractor if they are to certify it themselves.

Unearthed lighting points are still commonly found. 10mA leakage from one point is abnormal and, earthing or no earthing, requires investigation. A proper EICR will pick it up, although it is no secret that many EICRs are very sloppily done. My experience of rubber cable (VIR or TRS) is that the mechanical soundness of the insulation varies from absolutely fine to non-existent, but rarely does it lose its otherwise excellent insulation resistance.
