@MissLucyEyelesbarrow you mentioned the Housing Act 1988. Clearly your reading didnt extend as far as section 5.
5 Security of tenure.[F1(1)An assured tenancy cannot be brought to an end by the landlord except by—
(a)obtaining—
(i)an order of the court for possession of the dwelling-house under section 7 or 21, and
(ii)the execution of the order,
(b)obtaining an order of the court under section 6A (demotion order), F2...
(c)in the case of a fixed term tenancy which contains power for the landlord to determine the tenancy in certain circumstances, by the exercise of that power[F3, or
(d)in the case of an assured tenancy—
(i)which is a residential tenancy agreement within the meaning of Chapter 1 of Part 3 of the Immigration Act 2014, and
(ii)in relation to which the condition in section 33D(2) of that Act is met,
giving a notice in accordance with that section,]and, accordingly, the service by the landlord of a notice to quit is of no effect in relation to a periodic assured tenancy.
(1A)Where an order of the court for possession of the dwelling-house is obtained, the tenancy ends when the order is executed.]

(b)a surrender or other action on the part of the tenant[F6, or
(c)the giving of a notice under section 33D of the Immigration Act 2014,]
then, subject to section 7 and Chapter II below, the tenant shall be entitled to remain in possession of the dwelling-house let under that tenancy and, subject to subsection (4) below, his right to possession shall depend upon a periodic tenancy arising by virtue of this section.
(3)The periodic tenancy referred to in subsection (2) above is one—
(a)taking effect in possession immediately on the coming to an end of the fixed term tenancy;
(b)deemed to have been granted by the person who was the landlord under the fixed term tenancy immediately before it came to an end to the person who was then the tenant under that tenancy;
(c)under which the premises which are let are the same dwelling-house as was let under the fixed term tenancy;
(d)under which the periods of the tenancy are the same as those for which rent was last payable under the fixed term tenancy; and
(e)under which, subject to the following provisions of this Part of this Act, the other terms are the same as those of the fixed term tenancy immediately before it came to an end, except that any term which makes provision for determination by the landlord or the tenant shall not have effect while the tenancy remains an assured tenancy.
