What is the difference between an EIC/MEWIC and an EICR? It is my understanding that anyone can issue an EICR for work after it has been completed by someone else.You could argue extenuating circumstances, and that the electrical work is not notifiable under Part P, but you are still left with work that does not have an EIC/MEWIC and as such does not comply with the Electrical Regulations.
You will have to convince the LABC that the work is not notifiable, and without an EIC/MEWIC, that is going to be very hard to do.
Do the initial plans indicate that the existing circuits are to be extended rather than new circuits installed?
The conversion did not require any plans and thus there was not mention of any electrical work. I would imagine it should be obvious that any garage conversion will require at least some electrical work anyway.
