It has long been established that poor quality housing conditions adversely affects health, and the longer the exposure to poor conditions, the greater the impact on physical and mental health. It has been estimated that poor housing in England costs the NHS £4.1 billion per year.
The Stock Condition Study advises that the best predictor for the overall condition of housing stock is the age of the properties. The age of a dwelling also affects energy efficiency as building techniques and regulations have changed over time, as well as additional wear and tear to the property.
