Ceiling insulation is generally the easiest, cheapest and most effective insulation to install in your home. It's a great place to start making your home warm, comfortable and healthy to live in.
Hot air rises, so for most homes making them easier and cheaper to heat properly starts with good ceiling insulation. Fortunately, ceiling insulation is relatively easy to install in houses with accessible roof spaces.
Do you qualify for funding?
Warm Up New Zealand: Heat Smart is the government insulation programme. It offers a subsidy to get your insulation installed through an approved service provider. For the majority of people, going through the programme is the hassle free way to have your insulation checked and find out what you need installed.
If your house was built before 2000, you may be eligible for help - find a provider in your aread and read more about Warm Up New Zealand: Heat Smart funding.
Check your insulation
If you can do it, get a step ladder and pop your head through the hatch into your roof space and have a look to see if you have insulation.
If there is no insulation on top of your ceiling, then you need to get some.
You will need to add a top up layer of insulation if there is some insulation up there, but it:
- is less than 12 cm thick (i.e should be thicker than the height of the ceiling joists)
- doesn't cover the whole ceiling
- has gaps in it, or places where it is squashed or tucked in
You need to remove the old insulation and start again with a new layer if:
- it is wet or damp in areas
- or has been damaged by rodents or birds

If you can't check your own insulation, or aren't sure if you need any, get a professional to come and have a look for you. It's free and if you do need some insulation, they can tell you if you qualify for funding.
What sort of insulation?
If you are getting your insulation installed under the Warm Up New Zealand: Heat Smart programme then you know that the insulation you are getting is the right thickness for your location and situation and meets both EECA's stringent requirements and any applicable Standards.
If you have a preference you could choose between blanket or biscuit insulation, or from the different materials insulation is made from i.e. wool, polyester, glass etc. Shop around to find a provider that uses the type you want.
If you don't have any specific preferences, then your decision might be more price driven. If so, get a quote from 2 or more providers if you can and compare them.
Loose fill insulation does not meet EECA's requirements for funding for a number of reasons. (see more information about ceiling insulation below)
