5.—(1) Subject to sub-paragraph (2), in the case of a mover whose housing benefit was in the form of a rent allowance, the authority which, prior to the mover ceasing to be entitled to housing benefit, was paying that allowance, shall make an extended payment to that mover calculated on the same basis as in paragraph 3 and, for these purposes, the mover shall be treated as continuing to occupy and be liable to make payments in respect of the dwelling he was occupying as his home immediately before he ceased to be entitled to housing benefit.
(2) Notwithstanding sub-paragraph (1), in a case where that mover's liability to make payments in respect of the second dwelling would be to a housing authority, any extended payment shall be made by that housing authority and shall be determined as provided in paragraph 7(b).
