In some areas "No MoT" is dealt with by way of a fixed penalty of �60.
If summoned to a magistrates' court you will receive a fine not much in excess of that, plus about �35 costs plus �15 Victim Surcharge.
As kempie says, no points. You will not be charged with failing to produce. You cannot produce what you do not have and failing to produce is only charged when you have the document but do not produce it within seven days. The substantive offence of no MoT will be the only one charged.
