Understanding mixed tenure in English social housing

This report: quantifies the ratio of social tenants to private tenants across social housing developments in England explores behavioural challenges to installing energy efficiency and low-carbon heating measures in mixed tenure social housing It highlights barriers for different groups, such as trust, communication, and financial concerns, and notes that motivations and willingness to participate vary across residents, with challenges both before and after installation.

Key Findings Quantitative research findings This quantitative research analysed data from the National Energy Efficiency Data Framework (NEED), in addition to other sources. In this report, the ‘social tenant ratio’ describes the ratio of social housing dwellings to all dwellings within a social housing development. The higher the social tenant ratio, the lower the level of mixed tenure. The key findings are: • The analysis identified 459,262 developments in England which are, or have the potential to be, mixed tenure. The research estimated that these developments contain approximately 3.33 million social dwellings in total. • According to the analysis, the mean social tenant ratio across social housing developments in England is 80%, and the median social tenant ratio is 97%. This suggests that the social tenant ratio can vary a great deal between developments. • Converted flats have a higher level of mixed tenure (i.e. a lower social tenant ratio) than purpose-built flats. Purpose-built flats have a median social tenant ratio of 91%, while converted flats have a median social tenant ratio of 50%. Purpose-built flats represent more than half (54%) of all ‘multi-dwelling developments’ identified as being, or having the potential
