What Makes a House Unfit for Human Habitation in the UK?

In the UK, every home must meet certain standards to be considered safe and livable. If a property fails to meet these standards, it can be deemed "unfit for human habitation." This means the property poses a risk to the health or safety of its occupants. Ensuring homes are safe is a legal requirement under the Homes (Fitness for Human Habitation) Act 2018, which outlines landlords' responsibilities to maintain their properties. This article will explain what makes a house unfit for human habitation in the UK, the legal obligations of landlords, and what tenants can do if they find themselves living in unsuitable conditions.

What Does "Unfit for Human Habitation" Mean?

A property is considered unfit for human habitation if it has serious defects or hazards that make it unsafe or unsuitable for people to live in. These hazards can range from structural issues to poor living conditions that put tenants' health at risk.

The Homes Act, which came into force in March 2019, aims to ensure that rented properties in England and Wales are safe, healthy, and free from hazards. Landlords are legally required to ensure that their properties are fit for habitation throughout the tenancy.

Key Factors That Make a House Unfit for Human Habitation

There are several conditions that can cause a property to be deemed unfit for human habitation. These include:

  1. Damp and Mould

Dampness and mould growth are common problems that can lead to serious health risks, particularly for people with respiratory conditions like asthma. If a property has significant damp or mould that affects the living conditions, it could be considered unfit for habitation.

  • Rising damp: Moisture from the ground seeps up through the walls and floors.
  • Penetrating damp: Water enters the property from the outside, often due to damaged roofs, walls, or windows.
  • Condensation: Poor ventilation can lead to condensation buildup, encouraging mould growth.
  1. Structural Problems

Structural defects such as major cracks in the walls, subsidence, or unsafe foundations can make a house dangerous. These issues not only compromise the building's stability but also pose serious risks to the occupants.

  • Cracks in walls: Significant cracks or signs of subsidence could mean the property is unstable.
  • Roof damage: Broken roof tiles or leaking roofs can lead to water damage and pose a danger if they collapse.
  • Faulty foundations: If the foundations are unstable, the property may shift, causing walls to crack and making the structure unsafe.
  1. Insufficient Natural Light or Ventilation

Every habitable room must have adequate natural light and ventilation. A lack of windows or ventilation can lead to poor air quality, damp, and increased humidity levels, all of which can negatively impact health.

  • No windows or poor light: Rooms without windows or with blocked light sources are not considered fit for habitation.
  • Inadequate ventilation: Poor ventilation can trap moisture and lead to issues such as damp, mould, and unhealthy indoor air.
  1. Unsafe Heating and Insulation

A property must have adequate heating and insulation to ensure it is warm and energy-efficient. A lack of heating, particularly during winter, can make a home uninhabitable. Similarly, inefficient insulation that leads to high energy costs or excessive cold can render a property unfit.

  • No heating system: If a property lacks a functioning heating system, it will not meet habitability standards.
  • Poor insulation: Homes that are poorly insulated can be too cold, increasing the risk of illnesses like hypothermia.
  1. Inadequate Sanitation Facilities

A property must have adequate and functioning sanitation facilities, including toilets, sinks, and baths or showers. If the plumbing is faulty or there is a lack of clean water, the property could be considered unfit.

  • No access to clean water: If the property lacks access to fresh, clean water, it is unsafe to live in.
  • Broken toilets or sewage issues: If the sanitation system is faulty and toilets or drains aren’t functioning, the property is uninhabitable.
  1. Unsafe Electrical Wiring or Gas Appliances

Faulty electrical systems or gas appliances pose serious hazards, including the risk of fires, electric shocks, or carbon monoxide poisoning. Landlords are required to ensure that electrical wiring and gas appliances are in safe, working condition.

  • Unsafe electrical wiring: Exposed or faulty wiring that increases the risk of fires or electrical shocks.
  • Gas safety: Faulty boilers, cookers, or heating systems can cause gas leaks or carbon monoxide poisoning.

Landlords must provide a valid Gas Safety Certificate (CP12) every year and ensure that all gas appliances are safe to use.

  1. Infestations

If a property is infested with pests such as rats, mice, cockroaches, or bedbugs, it can be deemed unfit for habitation. Infestations not only cause damage to the property but also pose significant health risks to tenants.

  • Rodent or insect infestations: These can lead to unsanitary conditions and are a common reason for deeming a house unfit.
  1. Overcrowding

Overcrowded living conditions, where too many people live in a property that is too small, can create health and safety hazards. This can occur if a landlord rents out a property with too few bedrooms or inadequate living space for the number of tenants.

  1. Fire Hazards

A property must be free from fire hazards and should have appropriate fire safety measures in place, including smoke alarms, carbon monoxide detectors, and fire exits. Properties that are at high risk of fires or lack proper fire safety equipment may be considered unfit for habitation.

  • No smoke alarms: All rental properties must have working smoke alarms on each floor and carbon monoxide alarms in rooms with solid fuel appliances.
  • Inadequate fire exits: Properties must have clear and accessible fire exits to be deemed safe.

Legal Obligations for Landlords

The Homes (Fitness for Human Habitation) Act 2018 requires landlords to ensure that their properties are safe, healthy, and fit for habitation throughout the duration of the tenancy. This includes:

  • Addressing repairs promptly: Landlords must fix any defects that could render the property unfit for habitation.
  • Ensuring safety standards: Electrical, gas, and fire safety standards must be maintained, with regular inspections and certificates provided.
  • Maintaining adequate living conditions: Damp, mould, structural problems, and sanitation issues must be addressed to keep the property fit for human habitation.

Failure to meet these legal requirements could result in tenants taking legal action, including claims for compensation or demands for the landlord to carry out repairs. In severe cases, local authorities may intervene, ordering repairs or even prohibiting the property from being rented out.

What Can Tenants Do if Their Home is Unfit?

If a tenant believes their home is unfit for human habitation, they have the legal right to take action. Here’s what tenants can do:

  1. Report the Issue to the Landlord: Tenants should first notify their landlord in writing of any problems and request repairs. Landlords are legally required to respond promptly to address serious issues.

  2. Contact the Local Council: If the landlord fails to act, tenants can contact their local council’s housing department. Councils have the authority to inspect the property and issue improvement notices if the home is deemed unfit.

  3. Take Legal Action: Under the Homes Act, tenants can take their landlord to court if they fail to make necessary repairs or address habitability issues. Courts can order landlords to carry out repairs or pay compensation to the tenant.


Ensuring a property is fit for human habitation is a fundamental responsibility for landlords in the UK. Tenants living in unsafe or unhealthy conditions have the right to demand improvements and take legal action if their homes are unfit. For landlords, it’s important to stay on top of property maintenance, address hazards, and comply with legal safety standards to ensure their properties remain habitable and compliant.
