Tenancies that are governed by Part 4 of the 2004 Act and that started on or before 24 December 2016 run in 4-year cycles. Tenancies that started after 24 December 2016 run in 6-year cycles.
During the first 6 months of a tenancy, the landlord can ask you to leave without giving a reason (unless you have a fixed-term tenancy) but must serve a valid written notice of termination, allowing a minimum 28-day notice period. Only 7 days’ notice is required in the first 6 months if your behaviour is seriously anti-social or threatens the fabric of the property.
For a tenancy that has lasted between 6 months and 4 years – known as a Part 4 tenancy – the landlord can end it only in the following circumstances:
or for the following 3 specific reasons:
See 'Reasons and notice of termination' below for more details.
Tenancies that started on or before 24 December 2016: When the 4-year cycle of the tenancy has ended, a new tenancy starts, known as a further Part 4 tenancy. As at the start of your original tenancy, the legislation currently provides that your landlord may end this tenancy at any time during the next 6 months without having to give a reason. (This rule is due to change shortly.) You must now get 112 days’ notice (16 weeks). After 6 months you again acquire security of tenure and you are now 6 months into a further cycle, which will now last 6 years.
Tenancies that started after 24 December 2016: The further Part 4 tenancy will start when the first 6-year cycle of the original tenancy has ended.
