Standard rent The controlled rent was known as the standard rent. It was the rent of a letting on 3 August 1914; or, where there was no letting on that date, the rent the dwelling had last been let for before that date; or, in the case of a first letting after 3 August 1914, the rent at which it was first let. Security of tenure Under the provisions of the Act, a tenant who paid the rent and observed other conditions of the tenancy, could only be evicted if the landlord could satisfy the Courts on certain grounds specified in the Act. These were: that the tenant had committed waste or caused nuisance or annoyance to neighbours; or, that the premises were reasonably required by the landlord for his own occupation, or that of an employee. In addition, the Courts could grant possession on any other ground it considered satisfactory. Premiums After 25 November 1915, premiums were not allowed to be paid by a tenant on the grant, renewal or continuance of any tenancy. Any amount paid was recoverable unless it was made payable by an agreement entered into before 4 August 1914. (Leases for 21 years or more were later excluded by the Courts (Emergency Powers) Act 1917). Rates The Statement of Rates Act 1919 required any owner in England and Wales who received rent that included rates to show the amount in the rent book. The equivalent Scottish Act is the House Letting and Rating (Scotland) Act 1920. Further extensions and amendments to the 1915 Act were made by the Acts of 1917, 1918 and two in 1919. Control was exempted from houses built alter 2 April 1919 or in process of construction at that date. Rent control and security of tenure hardly proved to be such temporary measures as had been originally intended. Full control 1920 to 1923 Following the report of the Salisbury Committee into the continuing deterioration in the housing supply, the Increase of Rent and Mortgage Interest (Restrictions) Act 1920 was passed, which consolidated and amended the earlier legislation. Most of the provisions were intended to be for a period of three years but they were successively extended and amended. Any remaining provisions were repealed and consolidated by the Rent Act 1968 and in Scotland by the Rent (Scotland) Act 1971. The 1920 Act is still the foundation of the modern law; most
