As my colleague Emilie Pownall's helpful ebriefing below explains, the eviction ban has been extended to 31 May 2021. This no doubt aligns with the timing for the route out of lockdown. 

The requirement to give six months notices on s21 notices and Notices for Seeking Possessions (NSPs) save for certain circumstances e.g. for cases involving antisocial behaviour, is also extended to the same date. We still await the regulations to confirm if the exemptions to the eviction ban or the notice periods will be any different but we expect not.
