(3) Where a parent has eligible housing costs and another person who is not a member of his family is also liable to make payments in respect of the home, the amount of the parent’s housing costs shall be his share of those costs [but, where that other person does not make those payments in circumstances where head (a) of paragraph 4(2) of Schedule 3 applies, the eligible housing costs of that parent shall include the housing costs for which, because of that failure to pay, that parent is treated as responsible under that head].
