REQUIRED NOTICE PERIOD

A notice can be issued more than two months before the 
end of a tenancy but it should not be dated to expire on or 
before the last day of the tenancy. For example, if a Section 
21 notice was issued four months before the tenancy was 
due to end, the notice would have to be dated after the last 
day of the fixed term.

If a section 21 notice is issued during the initial fixed term of a 
tenancy to regain possession at the end of the fixed term tenancy, 
then should the landlord decide to grant another fixed term, 
a new section 21 notice would be required to regain possession.
