The Landlord and Tenant Act 1985 is a key piece of legislation in the United Kingdom that outlines the rights and responsibilities of both landlords and tenants. It aims to ensure that rental properties are safe and well-maintained, providing tenants with essential protections against unfair practices. This Act requires landlords to keep their properties in good repair and to ensure that essential services, such as heating and hot water, are provided. It also gives tenants the right to challenge excessive rent increases and provides a framework for resolving disputes between landlords and tenants.
