Home Extension & Renovation Cost Index
The HERC Index rose by 1.74% in the three months to March. Main contributors were:
- Polystyrene (improved product for better bushfire protection)
- Price increases for aluminium windows, and
- Increased engineering certification requirements.
As the comparison chart shows, both the HERC Index and Residential Property Price Index outpaced the Consumer Price Index significantly in the last half of 2019.
