There have been numerous Acts of Parliament controlling residential tenancies. Often they have left the law intact for existing tenants, while reforming the regime for new ones. The rateable value frequently defined limits of application, so the abolition of domestic rates has added further complexities. The result is that even experienced professionals can find it hard to be sure exactly what the current criteria are. This unusual guide helps to clarify the position. For each type of tenancy, every key element - type of property, type of landlord, commencement date - is set out in standard sequence in checklist form. The large pages enable the total position to be displayed and rapidly compared. The reader can quickly find answers to three types of questions: first, what are the circumstances giving rise to a particular type of tenancy? Secondly, what are the consequences in respect of security of tenure, succession and rent? And thirdly, what type of tenancy does a particular tenant have? Details are necessarily brief, but statutory references are included for those who need to take a point further.
