% of dwellings that reported not using heating, by territorial authority
Based on 2018 Census data for dwellings that reported "no heating used" for their main type of heating. Main types used means those that the respondent has used most often during periods when heating was required - the type or types they generally rely on. Any forms of heating that a respondent uses relatively rarely compared with others are excluded. Also excluded are any heating types available in the dwelling that are not used at all or are disconnected or broken.
