What earns a certificate, activity by activity
Which activity your job sits under, whether the product qualifies, and how many times one address is allowed to claim.
Everything in this section
- Which Victorian Energy Upgrades (VEU) activities cover HVAC workNobody maps the activity numbers for installers, so here they are. Which one your job sits under, and the one that keeps getting mixed up with lighting.
- Activity 6 categories, 6A to 6H, and their kW bandsEvery Part 6 category with its capacity band, the two that are for business premises only, and the multi-split rule about matching the manufacturer.
- The eleven Part 6 scenarios, and why they set the moneyWhat you take out decides how many certificates a job earns. All eleven scenarios, the caps on four of them, and how long the scheme assumes each lasts.
- The Victorian Energy Upgrades (VEU) efficiency floors, by categoryMinimum heating and cooling efficiency ratings for every Part 6 category, on GEMS Cold Zone figures, and why a GEMS 2013 registration rules a unit out.
- The Victorian Energy Upgrades (VEU) refrigerant rule and its 15 kW cut-offBelow 15 kW cooling, the refrigerant's global warming potential (GWP) must be under 700. R32 passes, R410A doesn't. At 15 kW or more, the rule doesn't apply.
- How many upgrades one address can ever claimOnce an address has had enough upgrades, Schedule 4 blocks any more claims there. The limit changes with the job type and whether the old unit came out.
- Seven activities that no longer earn certificatesGas space heating, evaporative coolers, underfloor insulation and four more, with the date each one stopped and the rule change that ended it.
- Activity 28, the gas ductwork rebate almost nobody claimsTake out the old gas heating ductwork, put new duct in to AS 4254, and there's a certificate in it. Here's what we know, and the figures we couldn't find.
- Activity 44 and the $10,000 commercial co-paymentThe commercial and industrial heat pump water heater activity, its $10,000 minimum co-payment, and why commercial HVAC upgrades now lean on the VEU.
- There's no Victorian Energy Upgrades (VEU) rebate for hydronicA hydronic space heating activity was under consultation in April 2026, and it still isn't claimable. Don't quote a rebate that doesn't exist yet.
