The fact sheet and sizing advice you owe before they sign

Before the customer agrees, you owe them three things. The current consumer fact sheet. Clear, accurate advice on whether the product suits their home. And a straight answer on whether your proposed size matches the fact sheet. It covers residential reverse cycle jobs (Part 6 categories 6A, 6B and 6D to 6F) and water heating (Parts 1 and 3).

What are the three duties?

  1. Give them the current fact sheetThat's the Victorian Energy Upgrades (VEU) Space Heating and Cooling Consumer Fact Sheet, or the Water Heating one, as published by DEECA (the Department of Energy, Environment and Climate Action). Current matters, so don't hand out a PDF you saved two years ago.
  2. Tell them whether it suits their houseClear and accurate, and based on their actual house. That's your judgement on site, not what the brochure says.
  3. Tell them whether your size matches the fact sheetThis is the easy one to miss. You have to say whether the size you're proposing is consistent with the size the fact sheet recommends. If you're deliberately going bigger or smaller, say so and say why.

And the timing is the hard part. All three happen before the customer agrees. Do them at installation and you haven't met the requirement.

What sizes does the fact sheet recommend?

DEECA, Choosing the right size reverse cycle air conditioner. For ducted systems the guidance is 1.1 to 1.4 kW of heating output for every 10 m².
Floor areaRecommended capacity
Up to 20 m²2.5 to 3 kW
21 to 40 m²3 to 5 kW
41 to 60 m²5 to 8 kW
Over 60 m²8 kW and above
DEECA, Choosing the right size hot water system.
BedroomsHot water storage
1 to 2150 to 225 L
3225 to 300 L
4 or moreOver 300 L

Be clear about what these are. They're the figures the scheme measures your advice against, not a load calculation. If a proper assessment of the house gives a different answer, you don't have to drop your own judgement. You just have to tell the customer about the difference.

Get today's fact sheet yourself

The energy.vic.gov.au site wouldn't let us read the fact sheets directly, so we checked them using Internet Archive copies from February 2026. The sizing figures above are the ones we confirmed from those copies.

Because you have to hand over the current fact sheet, open the official DEECA page yourself and take today's version. Don't rely on our numbers being this week's.

Working out whether to get accredited?

It's a real decision with real numbers on both sides, and most of the people offering advice make money whichever way you go.

Kevin has no stake in which way you go. Ask him.

Who this is for: small and medium HVAC contractors in Victoria. If you're a homeowner after a rebate or a repair, you need a licensed contractor, not us, and yours can point you the right way.
