concepts of the Rent Acts are derived from it. It is suggested as a first source of reference for any original concepts which are not included in this brief summary. Scope of control The standard rent and rateable value limits were increased to £105 in London, £90 in Scotland and £78 elsewhere, and so applied to the great majority of let houses in the country. The concept of "statutory tenant" was introduced in this Act. Premises used for business, trade or professional purposes, or for the public service were brought within the Act for one year (with slightly different percentage increases to those outlined below for dwellings). New dwellings continued to be excluded from control. The 1920 Act did not apply to houses erected, or in the course of erection, on 2 April 1919, nor to those that at that date or later were being reconstructed into two or more separate and self-contained flats or tenements. A measure of control was introduced for the first time to a furnished letting of a dwelling covered by the Act. This control related to abnormal or excessive profits. In the latter case, the landlord was liable to a fine of up to £100. Standard rent The Act allowed increases in rent of up to 40% and in mortgage interest of 1% (up to a maximum of six and one half per cent). The 40% was made up of two elements. An increase of 15% was allowed, to compensate the landlord for the fall in the value of money during the Great War. A further increase in rent of 25% was allowed to cover expenditure on repairs where the landlord did the repairs. This latter increase could not be levied on tenants of unfit dwellings or dwellings in disrepair. In fact, it could be levied but the tenant (or the sanitary authority) could go to court to have it suspended until the repairs had been carried out. Increases were also permitted, as a percentage of the relevant expenditure, following improvement or structural alteration. A tenant of a furnished dwelling was able to go to the county court (in Scotland the Sheriff Court) for an order to freeze the rent at a specified level and for repayment of any rent already paid in excess of that level. Premiums The Act now made it a penal offence, liable to a fine of £100, to require a
