Not exactly.What would be the process of fitting a new consumer unit? Would there be an EICR first?
However the installation will have to be inspected at some time to make sure it will be safe.
For a new CU an EIC - Electrical Installation Certificate - will have to be issued.
How do you know that needs doing?If so I should probably trace the lighting circuit and its junction boxes and tighten the terminals, so I don’t have to pay for more of the electrician’s time.
