Which Victorian Energy Upgrades (VEU) activities cover HVAC work
Five VEU activities matter for HVAC work. Part 6 is space heating and cooling. Parts 1 and 3 are water heating. Part 28 is gas heating ductwork, and Part 44 is commercial heat pump water heaters. Part 48 is ceiling insulation, which sits next to HVAC work but isn't HVAC.
- Space heating and cooling
- Part 6the one most jobs use
- Water heating
- Parts 1 and 3residential
- Gas heating ductwork
- Part 28new duct to AS 4254
- Commercial heat pump hot water
- Part 44$10,000 minimum co-payment
Which activity number covers which job?
The regulations list each activity as a numbered Part. So when someone says "activity 6" and someone else says "Part 6", they mean the same thing.
| Part | What it covers | Who it's for |
|---|---|---|
| 6 | Space heating and cooling. Reverse cycle air conditioners, categories 6A to 6H | Residential and business |
| 1 and 3 | Water heating, including heat pump water heaters | Residential |
| 28 | Take out the old gas heating ductwork and put new duct in to AS 4254 | Where there's existing ducted gas |
| 44 | Commercial and industrial air source heat pump water heaters | Commercial and industrial |
| 48 | Ceiling insulation. Started 14 April 2026, $200 minimum co-payment | Residential, next to HVAC work |
Part 6 covers most HVAC work and most of the money. It's also where nearly all the tricky bits are. It has eight categories, set by size and whether it's ducted, and eleven scenarios, set by what you're taking out. Both decide what a job is worth.
Common
mix-up
Activity 34 is lighting, not HVAC
You'll see activity 34 come up when people talk about HVAC eligibility. It's a lighting activity. So are 27 and 35.
If somebody is weighing up activity 6 against activity 34 for your job, one of those numbers is wrong, and it isn't 6. The ones that actually matter for HVAC are Part 6, Parts 1 and 3, Part 28 and Part 44.
It's a small thing, but it's the kind of mistake that gets copied from site to site until everyone believes it.
Which activity does my job sit under?
- Replacing or installing a reverse cycle system? Part 6.Then work out two things. The category comes from the capacity and whether it's ducted. The scenario comes from what you're taking out.
- Replacing a hot water system? Parts 1 or 3 for homes, Part 44 for commercial.The commercial one carries a $10,000 minimum co-payment, which makes it a very different conversation with the customer.
- Replacing ductwork on a gas heater? Part 28.It's rarely claimed, and the new duct has to be installed to AS 4254.
- Doing more than one of those on the same job?Check how many upgrades the address has already had before you quote. Past upgrades there can block a claim completely.
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.
If you're looking at a job and the answer isn't obvious, ask Kevin.
