The Victorian Energy Upgrades (VEU) program is changing how residential heating and cooling incentives work. For installations completed on or after 30 September 2026, multi-split rebate calculations are capped at 20kW of heating/cooling capacity, and the minimum customer co-payment rises to $3,000 for ducted and larger multi-split systems.

Both apply to residential heating and cooling upgrades completed on or after 30 September 2026.
Incentive (VEEC) calculations for multi-split reverse-cycle air conditioners - including multi-split ducted products - will be capped at 20 kilowatts of heating and cooling capacity. The cap applies to installations in residential premises only. Larger systems can still be installed - but any capacity above 20kW earns no additional rebate value.
The minimum out-of-pocket customer contribution rises from $1,000 to $3,000 (including GST) for ducted reverse-cycle systems and for multi-split systems with a heating or cooling capacity of 10kW or more - either capacity crossing 10kW triggers the higher minimum. Multi-splits under 10kW heating and cooling stay at the $1,000 minimum.
| Before 30 Sep 2026 | From 30 Sep 2026 | |
|---|---|---|
| Multi-split incentive calculation - residential (incl. multi-split ducted) | Based on full installed heating/cooling capacity | Capped at 20kW heating/cooling capacity |
| Multi-split incentive calculation - non-residential | No capacity cap | No capacity cap (unchanged) - minimum co-payments still apply |
| Minimum co-payment - ducted reverse-cycle | $1,000 incl. GST | $3,000 incl. GST |
| Minimum co-payment - multi-split, 10kW+ heating or cooling | $1,000 incl. GST | $3,000 incl. GST |
| Minimum co-payment - multi-split, under 10kW heating and cooling | $1,000 incl. GST | $1,000 incl. GST (unchanged) |
| Minimum co-payment - single split, under 10kW | $200 incl. GST | $200 incl. GST (unchanged) |

Households replacing ducted gas heating with a large multi-split or ducted reverse-cycle system will see smaller rebates and a higher mandatory co-payment.
A standard single split under 10kW for one room is largely unaffected - rebate calculations stay the same and the minimum co-payment remains just $200 including GST.
The 20kW cap applies to residential installations only - commercial and other non-residential installs are not capped. The new minimum co-payment requirements still apply, however.
The stated rationale is right-sizing: oversized systems can short-cycle, waste energy and deliver less comfort. Capping incentives aligns rebates with actual household heating and cooling needs.
Quotes for large multi-split and ducted jobs are worth substantially more under the current rules. Help your customers commit before the deadline.
Any 20kW+ multi-split or ducted job that will complete on or after 30 September 2026 needs re-pricing: capped VEECs plus the $3,000 minimum co-payment.
