This research paper forms part of an ongoing programme of work examining the relationship between housing and health. The programme aims to explore how good housing and housing related services for older people and vulnerable adults can help prevent illness and promote independent, healthy living; how new partnership working can improve a neighbourhood’s capacity to care and help de-medicalise services; and how housing associations can help deliver better services and long-term cost savings for healthcare providers. This paper looks specifically at how using surplus NHS land to build supported housing can help meet demand and reduce the costs of care. It makes the case for thinking differently about cost savings in the NHS, notably in regard to alternative provision of supported housing through innovative partnerships between housing associations and NHS trusts. In particular, the paper aims to quantify possible future savings that can be made based on existing land disposal programmes. The evidence suggests that even by disposing of small parcels of surplus land significant savings can be realised over the long-term.
