Section 20 amends section 5 of the Protection from Eviction Act 1977. Subsection (1ZA)(a) sets out rules about the period of notice that a tenant can be required to provide when ending an assured tenancy. If a landlord and tenant agree in writing the amount of notice a tenant must provide when serving a notice to quit, this must not be more than two months. If there is no written agreement, a tenant must give notice at least two months before the date on which the notice is to take effect (i.e., at the end of a period of the tenancy). If the tenancy is a joint tenancy, where a joint tenant agrees a shorter notice period for a notice to quit with the landlord, all other joint tenants must also agree to the shorter notice period.
	Subsection (1ZA)(b) provides that for other tenancies where the Protection from Eviction Act 1977 applies, the notice to quit must be given at least four weeks before the date on which the notice is to take effect.
