The Housing Health and Safety Rating System (HHSRS), also known as 'The Rating System', was introduced as a result of the Housing Act (2004). It evaluates potential health and safety risks which could be caused by problems (or 'deficiencies') in homes.
The underlying principle of the HHSRS is that 'all residential premises should provide a safe and healthy environment for any potential occupier or visitor'.
