Tenancies commencing after the 24th December 2016

Further Part 4 tenancies
A ‘further Part 4 tenancy’ begins once the initial ‘Part 4 tenancy’ has finished. From the 24th December 2016, when a ‘further Part 4 tenancy’ commences, it lasts for 6 years for all tenancies
This also applies to tenants in Approved Housing Bodies.
Fixed term tenancies
A fixed term tenancy is a tenancy that lasts for a specific amount of time. A ‘Part 4’ tenancy runs alongside a fixed term tenancy, which means the tenant shall, after a period of 6 months and as in the normal course, become entitled to the provisions of a ‘Part 4’ tenancy (i.e. they can stay in the property for 6 years). This simply means that irrespective of the length of the fixed term lease, a tenant has an entitlement to remain in the dwelling for up to 6 years and the landlord can only terminate the tenancy on limited grounds See here for grounds on which a landlord can end a tenancy.
