The Victorian Energy Upgrades (VEU) efficiency floors, by category

Every VEU Part 6 category has a minimum seasonal heating rating (HSPF) and cooling rating (TCSPF), using the Cold Zone figures from the federal Greenhouse and Energy Minimum Standards (GEMS). The unit must also be registered to the GEMS 2019 Determination. Products registered to the GEMS 2013 Determination aren't eligible, however efficient they are.

What's the minimum efficiency for each category?

Four ratings get a floor. HSPF (Heating Seasonal Performance Factor) and TCSPF (Total Cooling Seasonal Performance Factor) are the seasonal heating and cooling ratings. ACOP (Annual Coefficient of Performance) and AEER (Annual Energy Efficiency Ratio) are the annual heating and cooling ratings. Higher is better on all four.

Source: VEU Specifications 2018 v25.0, Table 6.3. HSPF and TCSPF are the GEMS Cold Zone values. The kW sizes are rated standard cooling full capacity, as defined in the GEMS 2019 Determination.

Notice the pattern. Small units have the toughest heating floor. 6D needs HSPF 4.2, while 6G gets through on 2.7. That's likely because small units sell in the biggest numbers, so a higher bar there saves the most energy.

Why does the Cold Zone figure matter?

This is the bit that catches people reading a spec sheet. The floors use the GEMS Cold Zone HSPF and TCSPF. Brochures usually quote the mixed or average zone figure, which is a different number.

So a unit can look comfortably over the line on its brochure and still fail the VEU floor. Check the GEMS registration data, not the sales sheet.

Rules

A GEMS 2013 registration isn't eligible for Part 6

The product has to be registered to the Greenhouse and Energy Minimum Standards (Air Conditioners up to 65kW) Determination 2019. Products registered to the GEMS 2013 Determination aren't eligible for Part 6, however efficient they are.

This is about paperwork, not how well the unit runs. You'll mostly strike it with old stock and with models that have been on sale for years. The unit can work perfectly well and still not qualify.

It's also a reminder that there are two separate checks. One is the GEMS registration. The other is the Essential Services Commission (ESC) product register. Passing one tells you nothing about the other.

What would change these floors?

If the government brings in a new GEMS determination or lifts the minimum energy performance standards (MEPS), product eligibility and this table would move together. That's because the table is built on the GEMS ratings.

We couldn't confirm any MEPS increase in 2025 or 2026, so the figures above stand as at our September 2026 check. If you hear the minimum standards have changed, don't rely on this table until you've checked it again.

Not sure which activity your job sits under?

Getting the activity and the scenario right is what sets the money, and you need to get it right before you quote, not after you install.
