47.—(1) This regulation applies in any case where an individual (“the agency worker”)—
(a)is supplied by a person (“the agent”) to do work for another (“the principal”) under a contract or other arrangements made between the agent and the principal; but
(b)is not, as respects that work, a worker, because of the absence of a worker’s contract between the individual and the agent or the principal; and
(c)is not a party to a contract under which the individual undertakes to do the work for another party to the contract whose status is, by virtue of the contract, that of a client or customer of any profession or business undertaking carried on by the individual.
(2) In a case where this regulation applies, the other provisions of these Regulations shall have effect as if there were a worker’s contract for the doing of the work by the agency worker made between the agency worker and—
(a)whichever of the agent and the principal is responsible for paying the agency worker in respect of the work; or
(b)if neither the agent nor the principal is so responsible, whichever of them pays the agency worker in respect of the work,
and as if that person were the agency worker’s employer.
