Local authorities have, for many years, been required to let their dwellings on an incomerelated basis. At this stage only a very small number of tenancies, which are of a long standing nature, are on fixed rents. The costs of transferring tenancies of old age pensioners to fixed rents would depend on the level at which rents were fixed and the number of dwellings occupied by pensioners. As the determination of the rents of their dwellings is the responsibility of individual local authorities, information is not available in the Department to enable the costs sought to be computed.
