Many New Zealand homes already have insulation — but that doesn’t always mean it’s working effectively.
The Energy Efficiency and Conservation Authority (EECA) encourages homeowners to regularly check insulation condition and coverage to ensure homes stay warm, dry, and energy efficient.
Here’s how to tell if your insulation is still doing its job.
Signs your insulation may need attention
❄️ Your home feels cold or hard to heat
If rooms lose warmth quickly, insulation may be thin, damaged, or poorly installed.
💰 High power bills
Heating systems work harder when insulation isn’t performing properly.
💧 Dampness or condensation
Moisture can reduce insulation effectiveness and lead to mould problems.
🏚 Older insulation materials
Insulation installed decades ago may no longer meet today’s standards.
What to check in your home
EECA recommends checking:
Ceiling insulation thickness and coverage
Gaps or displaced insulation
Underfloor insulation condition
Signs of moisture or damage
A professional inspection is the safest way to assess performance accurately.
Why upgrading insulation matters

✔ Maintain indoor warmth
