This report by the University of Bangor makes the economic argument for investing in prevention at different stages of the life course, in particular, older people.
Commissioned by Public Health Wales, it brings together robust international and UK evidence on the relative cost-effectiveness and return on investment of devoting public sector resources to programmes and practices supporting older people.
In relation to housing, it notes that the Welsh Government spends around £50 million per year on adapting the homes of older and disabled people, helping them to live safely and independently.
For every £1 invested in Care & Repair there is £7.50 savings to the taxpayer. It comes to the conclusion that it is cost-effective to improve housing by providing heating and insulation for high risk groups of over 65s.
