The Housing Act 2004 is a significant piece of legislation in the United Kingdom that introduced various reforms to improve housing conditions. It established the Housing Health and Safety Rating System (HHSRS), which assesses risks to health and safety in residential properties. This system helps local authorities identify and address hazards in homes, ensuring safer living environments for tenants. Additionally, the act introduced measures to regulate the private rental sector, including the requirement for landlords to obtain a license for certain types of rental properties. This aims to improve standards in the rental market and protect the rights of tenants, promoting fair and safe housing practices.
