The use of properly operating and socially acceptable settlement systems of individual heating costs contributes to energy savings in the residential sector.

The main causes of irregularities in settlements of individual heating costs using heat cost allocators in housing sector in Poland are listed and described. There are presented proposals of existing irregularities elimination, in order to obtain adequate quality of the heating cost division in building into individual apartments.
