Making your Canterbury home warmer, drier, and cheaper to heat.
homes guide
If your home was built before 1991, there's a strong chance it's under-insulated. Most pre-1991 Canterbury homes have no wall insulation at all, and whatever ceiling insulation was originally installed has likely degraded, compressed, or been disturbed over the years. The result? A home that's expensive to heat, prone to condensation, and uncomfortable through our long Canterbury winters.
Retrofitting insulation is one of the most cost-effective upgrades you can make. It pays for itself through lower power bills, it makes your home healthier by reducing damp and mould, and you'll feel the difference from day one.
Canterbury's climate demands proper insulation
Our winters average between 1-10°C with regular frosts, and most Canterbury homes need heating for six months or more each year. We're classified as Climate Zone 3, the coldest zone in New Zealand, which means higher R-value insulation requirements than anywhere else in the country. The nor'wester winds add to the challenge, driving heat out of poorly insulated homes even faster.
What proper insulation does for your home.

20-40% Lower Heating Costs
Properly insulated homes need far less energy to stay warm. Most homeowners see the difference in their very first winter power bill.
Stop Up to 35% of Heat Loss
Uninsulated walls can account for up to 35% of a home's heat loss. Ceiling insulation addresses the biggest single source, rising warm air escaping through the roof.
Reduce Condensation and Mould
When surfaces are closer to room temperature, moisture stops condensing on them. Less condensation means less mould, fewer musty smells, and healthier air for your family.
Increase Your Home's Value
A warm, dry, well-insulated home is more attractive to buyers. Insulation is one of the highest-return upgrades you can make before selling.
Signs your home needs better insulation.
If two or more of these sound familiar, your home is likely under-insulated. The more boxes you tick, the more you stand to gain from an upgrade.
Rooms that stay cold no matter how much you heat them
Condensation running down windows on winter mornings
Power bills that seem too high for the warmth you get
Mould appearing on walls, ceilings, or in wardrobes
Noticeable draughts, especially around floors and walls
Uneven temperatures, warm lounge but freezing bedrooms
You may be eligible for EECA support.
Eligibility, contribution rates and qualifying products are set by EECA and updated from time to time, so the official site is always the source of truth.
The government's Warmer Kiwi Homes programme helps eligible homeowners with the cost of ceiling and underfloor insulation. It's administered by EECA — we're not the funding body, so we don't set the rates, decide who qualifies, or commit to a specific contribution on your behalf.
Check your eligibility directly with EECA before factoring it into your budget. Wall insulation is not covered by the programme.

We visit your home, check your existing insulation (ceiling, underfloor, and walls), measure up, and give you a clear, no-obligation quote.
