Decent Homes

What are decent homes?

The definition of a decent home is one that:
  • meets the current statutory minimum standard for housing
  • is in a reasonable state of repair
  • has reasonably modern facilities and services
  • provides a reasonable degree of thermal comfort
In short, in order for a home to be considered decent a home should be warm, weatherproof and have reasonably modern facilities.

Decent Homes are important for the health and well being of those living in them. Poor housing helps an area get a bad reputation. In short decent homes are a key element of any thriving sustainable community.

The Government made a commitment in 2000 to bring all public sector homes up to a decent standard by setting a 10 year target to ensure that all social housing meets the standard of decency by 2010.

Housing Standard

Housing Health & Safety Rating System (HHSRS) is the new risk assessment procedure for residential properties, replacing the Housing Fitness Standard from the 6th April 2006 in England. HHSRS also replaces the fitness standards as an element of the Decent Homes Standard.

The HHSRS states that dwellings should be free from category 1 hazards (hazard group A – physiological requirements, damp & mould). These hazards are described in the document as threats to health associated with ‘increased prevalence of house dust mites and mould or fungal growths resulting from dampness and/or high humidity's. It includes threats to mental health and social well being which may be caused by living in the presence of damp, damp staining and/or mould growth.’

Some of the category 1 hazards listed in the HHSRS scoring sheet are:
  • cold
  • damp & mould
  • heat
  • noise

How condensation can affect the fabric of homes and health

A common consequence of modern living and more energy efficient homes is excess water vapour. Most homes will experience condensation on their windows and in many cases windows will stream with water. Condensation can also lead to mould growth on walls and in some cases on soft furnishings and clothing. Condensed water on surfaces provides ideal conditions for mould spores already in the air to germinate and grow. Mould and condensation are both damaging and can lead to costly premature redecoration or replacement in housing. Dampness will also be evident through musty smells throughout the home.

There is now considerable evidence to support the view that mouldy housing has a detrimental effect on the physical and mental health of its occupants.

If the correct type of ventilation system is not fitted into a home
  • Occupants could end up living in unhealthy homes
  • There would be an accumulation of moisture which can lead to mould growth
  • There would be increased repair and maintenance costs
External pollutants could import problems into homes
  • Traffic fumes
  • Pollens
  • Industrial process pollutants
  • Noise
Too much ventilation can result in
  • Unnecessarily high running costs for occupants
  • Carbon emissions to the external environment
Ventilation, when fitted correctly, can provide a healthier living environment for the occupants, reducing health risks and protecting the fabric of the building from damage.




Indoor air quality and asthma

It is estimated that approximately 80% of all asthmatics are allergic to the droppings of the house dust mite. Dust mites are too small for us to see but they can be present in huge quantities in soft furnishings, mattresses and carpets. It is the inhalation of this allergen that can trigger an asthma attack. Dust mites breed in a humid environment found in homes which are poorly ventilated. By ventilating a home a hostile environment for the house dust mite is created; mite populations can fall and faeces production reduced. Clinical research has proven that whole home ventilation can play a significant part in controlling dust mite allergens.
