Is it necessary to renew a tenancy agreement which states: &quot;Expire on (but continuing thereafter by virtue of statute..)&quot;
<p>I have been living in UK for 10 years, lived in 5 different places. Only one of my previous landlords used to renew the contract every year. By renewing I mean signing a new contract and new dates but NO changes.</p>

<p>Is it necessary to do that? when there is no changes in the circumstances or the line above validates the contract even after the expiry date?</p>

<p>If this is a typical private sector tenancy, then it would initially be a fixed-term one year'assured shorthold tenancy' a type of assured tenancy. The <a href="http://www.legislation.gov.uk/ukpga/1988/50/section/5" rel="nofollow">Housing Act 1988 says</a>:</p>

<blockquote>
  <p>If an assured tenancy which is a fixed term tenancy comes to an end
  otherwise than by virtue of—</p>
  
  <p>(a) an order of the court of the kind mentioned in subsection
     (1)(a)
  or (b) or any other order of the court, or</p>
  
  <p>(b) a surrender or other action on the part of the tenant,</p>
  
  <p>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.</p>
</blockquote>

<p>So if the tenancy was not renewed then it would be replaced with a periodic tenancy. This has different rules to the fixed-term tenancy. Whether renewing the tenancy is necessary or not depends on whether either party strongly prefers the fixed-term tenancy to the periodic.</p>
