Calculation of earnings of self-employed earners: pensioners
43.—(1) Where the earnings of an applicant who is a pensioner consist of earnings from employment as a self-employed earner, the weekly amount of his earnings is to be determined by reference to his average weekly earnings from that employment—
(a)over a period of one year; or
(b)where the applicant has recently become engaged in that employment or there has been a change which is likely to affect the normal pattern of business, over such other period (“computation period”) as may, in the particular case, enable the weekly amount of his earnings to be determined more accurately.
(2) For the purposes of determining the weekly amount of earnings of an applicant to whom sub-paragraph (1)(b) applies, his earnings over the computation period are to be divided by the number equal to the number of days in that period and the product multiplied by 7.
(3) The period over which the weekly amount of an applicant’s earnings is calculated in accordance with this paragraph is to be his assessment period.
