To end an assured periodic tenancy, tenants must give a notice to quit. Prior to this Act, tenants could be required by the tenancy agreement to provide notice to quit in a particular way. This section provides that such notice must be given in writing, but landlords cannot specify a particular form of written communication.
	It also provides that tenants may withdraw a notice to quit under an assured tenancy if the landlord agrees, to allow flexibility for both landlord and tenants. These measures do not affect the rights of both parties to agree together to the tenant surrendering the tenancy.
