Rents Act 1954 and other related enactments (some twenty-four in all), without rationalising or simplifying them. The 1965 Act had previously provided the power by Ministerial Order for the progressive conversion of existing controlled tenancies to regulated tenancies. This power was never exercised and the Housing Act 1969 introduced a phased programme of conversion, determined by rateable values, and the qualification certificate procedure outlined below, for those controlled tenancies in good repair and equipped with standard amenities. Grants became available to provide dwellings by conversion or for improvements of existing dwellings and there were special grants for houses in multiple occupation. Grants to provide standard amenities were specified (e.g. £30 for a bath or shower; £50 for a water closet and £30 for a hot and cold water supply at a sink) The term "improvements" included the replacement of an existing fixture or fitting. Qualification certificates could be issued by a local authority for premises that had all the standard amenities and were in good repair. A certificate of fair rent issued by the Rent Officer stated what the fair rent would be once any missing standard amenities had been provided. A fair rent could then be determined (the application was supported by the certificate of fair rent) but the increase in rent was phased over a period of four years (two years if the work had been aided by an improvement grant). Amount attributable to services Rent Officers had previously informally shown an amount for the value of services on the register. The 1969 Act required there to be a note on the rent register of the amount attributable to the provision of services (but not if the charge for the services was variable). A note was now also required of the increase over the amount for services in the previous rent (which could be calculated by apportionment if necessary). This amount affected the phasing calculation. The Act introduced a new definition of a house in multiple occupation (HMO) and provided for registers and orders applying a management code. Powers were given to local authorities to close an HMO (or part of it) if it was not possible to provide a fire escape. It introduced the possibility of control orders to be followed by compulsory purchase orders. Directions were made to avoid or reduce overcrowding. In determining whether a long tenancy was a tenancy at a low rent, the
