Sch 3A para 7
(1) Notwithstanding the preceding provisions of this Schedule, where a person who makes or intends to make relevant supplies satisfies the Commissioners that any such supply is zero-rated or would be zero-rated if he were a taxable person, they may, if he so requests and they think fit, exempt him from registration under this Schedule. (2) Where there is a material change in the nature of the supplies made by a person exempted under this paragraph from registration under this Schedule, he shall notify the Commissioners of the change— (a) within 30 days of the date on which the change occurred; or (b) if no particular date is identifiable as the day on which it occurred, within 30 days of the end of the quarter in which it occurred. (3) Where there is a material alteration in any quarter in the proportion of relevant supplies of such a person that are zero-rated, he shall notify the Commissioners of the alteration within 30 days of the end of the quarter. (4) If it appears to the Commissioners that a request under sub-paragraph (1) above should no longer have been acted upon on or after any day, or has been withdrawn on any day, they shall register the person who made the request with effect from that day.
