onic illnesses, such as respiratory disease, are exacerbated by cold and damp homes and contribute to these avoidable excess winter deaths.”
Using an historical cohort study design the costs and outcomes of retrofitting social housing improvements were examined. Over 470 social housing tenants from nearly 230 households in Sunderland were surveyed both before and 12 months after installation of new boilers and double glazed windows by Gentoo, at no cost to the tenants. The cohort proved to be highly socioeconomically deprived; the vast majority of households had an income of less than £15,000 per year. Recruitment was staggered to counter any effect of seasonality. On average the cost of completing the housing improvements was £3725 per household.
After the housing improvements had been installed, six month household health service use costs reduced by £95 per home, equating to a 16% reduction in household NHS costs. On average a 69% reduction in hospital outpatient appointments was observed per household, as well as a 46% reduction in accident and emergency attendance and a 10% reduction in GP visits. For this cohort of 228 homes alone it is estimated that the NHS saved over £20,000 in six months after completion of the housing improvements. It was also found that the health status of main tenants significantly increased by almost 8% and financial satisfaction increased by 7%. Additionally, small non-significant improvements to main tenant happiness, life satisfaction, anxiety and well-being were also found.
After the home improvements were completed most households were able to heat all rooms in the home, where previously most households left one room unheated due to energy costs. Furthermore, over a third of households were no longer spending 10% or more of their income on energy bills, a key indication of reduced fuel poverty.
Health and Care Research Wales have funded PhD student Eira Winrow (CHEME, Bangor University) to further investigate the impact of housing on health and NHS expenditure.
