We have all heard in the last few years about the need to have a “healthy” home, but what this actually means is not always clear.  Here are a few comments from our team on what makes a healthy home and why it is important.


Research has shown that there is a clear link between your health (and your family’s) and the house that you live in. Cold, damp and mouldy houses increase negative health incomes. They pose the following risks:

  • Increased risk of respiratory infections (when indoor temperatures are under 16°C)

  • Stress on the cardiovascular system (when indoor temperatures are under 12°C)

  • Increased risk of the onset of asthma and symptoms are likely to worsen

  • Dampness and mould are associated with respiratory tract infections and bronchitis


The World Health Organisation recommends that our homes be at a minimum temperature of 18°C, or 20°C for homes with young children, elderly or ill people. Looking after your family means ensuring your home is warm and dry.


In New Zealand there is now a requirement for rental homes to meet a minimum Healthy Homes standard which details specific minimum standards for heating, insulation, ventilation, moisture ingress, drainage and draught stopping. These standards must be met by all private landlords by 1 July 2021.


The three essentials to create a healthy, energy efficient home are: keeping your home warm, ensuring your home is dry, and airing it out regularly [].


So, what practically does this mean:

  • Insulate: Insulation makes your home easier and cheaper to heat.  Chances are that your home has at least some insulation usually found in the ceiling. But insulation can be also be in the floor and exterior walls. Make sure your home is insulated. Ceiling and underfloor insulation has been compulsory in all rental homes since 1 July 2019. Check out the requirements on:


  • Minimise dampness in the home: Actions you can take to reduce dampness are - air your house regularly, dry washing outside and use extractor fans in the bathroom and kitchen. Rental properties are covered by the ventilation standards, check the requirements here:


  • Have an efficient heating system:  The type and size of the space will determine what type of heating will work efficiently for you and your family, however having a heating system is essential to ensuring you maintain a healthy home. A heat pump is one way to heat your home (and cool you in summer) and is one of the cheapest options to run.
