Subject to regulation 7, for the purposes of determining whether earnings-related contributions are payable in respect of earnings paid to or for the benefit of an earner in a given earnings period, and, if so, the amount of contributions, where in that period earnings in respect of different employed earner’s employments are paid to or for the benefit of the earner—
a
by different secondary contributors who in respect of those employments carry on business in association with each other;
b
by different employers, one of whom is, by virtue of Schedule 3 to the Social Security (Categorisation of Earners) Regulations 1978 F1, treated as the secondary contributor in respect of each of those employments; or
c
by different persons, in respect of work performed for those persons by the earner in those employments and in respect of those earnings, some other person is, by virtue of that Schedule, treated as the secondary contributor,
the earnings paid in respect of each of the employments referred to in this paragraph shall, unless in a case falling under sub-paragraph (a) it is not reasonably practicable to do so, be aggregated and treated as a single payment of earnings in respect of one such employment.

Where, under paragraph (1), earnings are aggregated, liability for the secondary contributions payable in respect of those earnings shall, in a case falling within paragraph (1)(a), be apportioned between the secondary contributors in such proportions as they shall agree amongst themselves, or, in default of agreement, in the proportions which the earnings paid by each bearer to the total amount of the aggregated earnings.
