18(1)The new tenancy is, subject as follows, to have effect on the same terms and conditions as those applicable to the original tenancy immediately before it ended.
(2)The terms and conditions of the new tenancy are to be treated as modified so as to reflect, so far as applicable, any changes made during the termination period to the level of payments for the ex-tenant’s occupation of the dwelling-house or to the other terms and conditions of the occupation.
(3)The terms and conditions of the new tenancy are to be treated as modified so that any outstanding liabilities owed by the ex-tenant to the ex-landlord in respect of payments for the ex-tenant’s occupation of the dwelling-house during the termination period are liabilities in respect of rent under the new tenancy.
(4)The appropriate national authority may by order provide for other modifications of the terms and conditions of the new tenancy.
(5)Nothing in sub-paragraphs (2) to (4) is to be read as permitting modifications of the new tenancy which would not have been possible if the original tenancy had remained a tenancy throughout the termination period.
(6)The terms and conditions of a new secure tenancy which arises by virtue of paragraph 17(a)(ii) are to be treated as modified so far as necessary to reflect the fact that the new tenancy is a secure tenancy and not an introductory tenancy.
