It is illegal to impersonate a corgi engineer.Slugbabydotcom is probably forging them anyway.
The regs state that an inspection is done every year by a competent person. I was corgi from 1997 to 2002 between then and 2004 when I re- registered I did do a few inspections here and there but by not using my expired number I did not in my view break the law.
Was I magically bereft of competence between 2002 and 2004? I would say not, others may say different. Debate it and do whatever but thats how it was.
