Regulation 4
A trained operative has a prescribed qualification for a particular type of work if—
an approved body has issued him with a certificate of competence showing that he has been assessed by an approved assessment centre as having achieved the relevant unit of competence as set out in Schedules 1 and 2 hereto and that certificate is registered in an approved register; or
he has obtained a qualification of another member state of the European Community which gives an equivalent guarantee of skill and competence to that given by the certificate of competence as required by sub-paragraph (a) above,
provided that, for a period of two months beginning with the day on which he is assessed as having achieved the requisite unit of competence, a trained operative shall be treated as having a prescribed qualification for that type of work, notwithstanding that an approved body has not issued him with a certificate of competence or that the certificate issued to him has not been registered as required by sub-paragraph (a) above.
If the works do not involve breaking up the road or are works only of the type referred to in regulation 3(2), a trained operative has a prescribed qualification if he has achieved the unit of competence set out as unit 2 in Schedule 1 hereto.
