All of us need houses that hold us heat in winter and funky in summer time, with out breaking the financial institution. Nonetheless, Australian houses constructed earlier than 2003 have a low common power ranking of 1.8 stars out of 10. This implies they’re typically uncomfortable to stay in and costly to run.
There’s a powerful case for a “renovation wave” of dwelling power upgrades throughout Australia. Decreasing the usage of fossil gasoline and enhancing the power effectivity of current housing by almost 50 % can also be central to attaining internet zero emissions by 2050.
Power-saving upgrades akin to photo voltaic panels, batteries, insulation, draught-proofing and sizzling water warmth pumps additionally cut back the price of power payments. So whereas there’s an upfront value, upgrades can cut back family bills in the long term.
We needed to seek out out what’s holding individuals again from getting energy-saving upgrades. We surveyed 100 Australian households and interviewed 19 individuals about their experiences. Our new analysis revealed 5 main limitations that cease these upgrades from being accessible to most households. Suppliers, governments and group organisations can all assist overcome these limitations.
1. Details about upgrades is complicated and overwhelming
Households informed us the quantity of data on the market about power saving upgrades is overwhelming and typically conflicting. There are a lot of various kinds of upgrades and product selections, making it difficult to establish which choices present the most effective worth and what to do first. Folks discovered it troublesome to know what data and which suppliers to belief.
Households want clear data from a trusted supply about what their houses want. Many governments internationally, akin to Scotland, present on-line sources and instruments to offer tailor-made recommendation to assist with this.
Power improve applications run by impartial group organisations and councils also can assist, akin to Rewiring Australia’s Electrify 2515 or Geelong Sustainability’s Electrical Properties Program. These applications use their experience to vet suppliers and guarantee households obtain good offers and top quality merchandise.
2. Properties want to interact a number of suppliers and tradespeople
Many households labored on their dwelling regularly, one improve at a time. Every improve concerned a labour-intensive technique of researching merchandise, deciding on corporations, getting quotes and managing the disruptions brought on by the set up. One Sydney house owner informed us:
The method of needing each a plumber and an electrician to alter to induction cooking was irritating. [We had] to coordinate availability instances and equipment supply.
Australians want corporations that may do a number of upgrades directly, to simplify and streamline the method. In Eire, the federal government helped stimulate a marketplace for organisations that may cowl all of the upgrades wanted by a family.
3. Households are shedding alternatives for simple upgrades
Yearly, Australians make investments billions in dwelling renovations. They spent greater than $3 billion within the December 2024 quarter alone.
Among the finest instances to enhance your property is throughout main renovations or when previous home equipment, akin to sizzling water programs, break down. Should you’re already going through disruptions and must spend cash, it may be a simple and less expensive method to enhance your property’s power effectivity on the similar time.
But our analysis discovered recommendation on energy-saving upgrades was hardly ever offered to individuals enterprise main renovations or emergency replacements until they requested for it. Households wanted to hunt out builders, architects and tradespeople who specialised in sustainability to get recommendation on an energy-saving renovation.
Offering power upgrades to houses needs to be a regular part of recent renovations. In any other case, households are lacking out on simple and extra reasonably priced alternatives to get these upgrades.
4. Many tradespeople lack data of energy-saving upgrades
Our analysis discovered tradespeople are the most typical level of contact for households. They could be a invaluable supply of data and recommendation to facilitate upgrades. Nonetheless, many households reported issue discovering tradespeople educated about – and keen to put in – energy-saving upgrades.
Some upgrades, akin to photo voltaic panels, require specialised workforces. Others, akin to sizzling water warmth pumps are normally put in by common plumbers and electricians.
Some tradespeople lack the data to advise on energy-saving upgrades or want coaching to put in new applied sciences to a excessive customary. This case leaves households susceptible to misinformation, with a scarcity of expert staff to do their upgrades.
Tradespeople require elevated assist and incentives to make energy-saving measures a part of their ability set. That is very true in regional areas, the place there are fewer merchandise and staff out there.
5. The prices are too excessive for a lot of households
A remaining, vital barrier was the price of dwelling upgrades, which frequently brought about households to drop out early within the course of. Australian households, significantly these with much less disposable revenue, want extra assist with the upfront value.
A method to do that is thru focused authorities rebates, that are at the moment solely out there in some areas. One other is reasonably priced and accessible financing, like that out there in Tasmania and the ACT. The nationwide Residence Power Upgrades Fund may be prolonged to verify out there finance matches the size of the problem.
Additionally wanted are long-term reforms akin to necessary disclosure of power efficiency when houses are offered and minimal power requirements for rental properties, that are at the moment solely required in some jurisdictions in Australia. When these are each addressed we are able to make snug and reasonably priced houses the norm moderately than the exception.

A worthwhile journey
Roadblocks apart, households additionally shared the enjoyment and satisfaction of finishing dwelling power upgrades. Whereas the journey was typically troublesome, those that reached the tip of the street had been overwhelmingly happy with the outcomes. A home-owner who had put in photo voltaic panels and undertaken draught-proofing and insulation in Adelaide stated:
It’s good to not have big electrical energy payments, however I discover it’s that each day stuff of truly being snug that makes the most important distinction.
