Energy-Efficient Rentals in Adelaide: How to Lower Your Power Bills

January 16, 2026

With electricity prices remaining high across South Australia, many renters are actively searching for energy-efficient rentals in Adelaide to help keep power bills under control. The good news is that energy efficiency isn’t just about brand-new homes or expensive upgrades. Even as a tenant, there are smart ways to choose a better rental and reduce energy use once you move in.

Here’s a practical, renter-friendly guide to understanding energy efficiency in Adelaide rentals — and how it can save you money year-round.


1. What Does “Energy-Efficient” Mean for Rentals in Adelaide?

An energy-efficient rental uses less electricity and gas to stay comfortable. In Adelaide’s climate, that means keeping homes cool during hot summers and warm during cooler winters without relying heavily on air conditioning or heaters. Features like insulation, efficient appliances, and good airflow all play a role.


2. Why Adelaide Tenants Often Face High Power Bills

South Australia has some of the highest electricity prices in the country. Many rental properties are older homes with poor insulation, inefficient heating and cooling, and single-glazed windows — all of which make power bills climb quickly, especially during extreme weather.


3. Heating and Cooling: Where Most of Your Energy Is Used

Air conditioners and heaters are usually the biggest contributors to power bills. Split systems are generally more energy-efficient than portable heaters or old wall units. Using ceiling fans, closing doors to unused rooms, and setting thermostats sensibly can make a big difference.


4. Insulation in Rental Properties: Why It Matters

Insulation helps keep heat out in summer and traps warmth in winter. Poor insulation means your air conditioner or heater has to work harder. While tenants can’t usually see insulation, uneven temperatures between rooms or rapid heat loss can be a sign it’s lacking.


5. Windows, Draughts, and Heat Loss in Adelaide Homes

Gaps around windows and doors let hot and cold air escape. Many Adelaide rentals still have single-glazed windows, which offer little thermal protection. Heavy curtains, draft stoppers, and sealing obvious gaps can significantly improve comfort without making permanent changes.


6. Appliances and Energy Ratings: What to Check Before You Rent

Older appliances can quietly drive up your electricity bill. Look for fridges, washing machines, and dishwashers with high energy star ratings. Even one inefficient fridge running 24/7 can cost hundreds more per year in power.


7. Solar Power in Adelaide Rentals: Can Tenants Benefit?

Some Adelaide rentals include solar panels, but benefits vary. If the electricity is connected directly to the property, daytime usage may be cheaper. However, some homes use embedded networks where savings are limited. It’s worth asking how the solar system is set up before signing a lease.


8. Lighting Choices That Can Instantly Reduce Power Costs

Lighting is one of the easiest areas to improve. LED bulbs use far less energy than halogen or incandescent lights and last much longer. Many landlords allow tenants to change light bulbs as long as originals are kept for moving out.


9. Hot Water Systems and Their Impact on Your Energy Bill

Hot water systems are another major energy user. Electric storage systems tend to cost more to run than gas, solar, or heat-pump systems. Shorter showers, washing clothes in cold water, and running appliances during off-peak times can help reduce costs.


10. Smart Technology in Rentals: Helpful or Just Hype?

Smart plugs, timers, and power monitors can help tenants track and reduce energy use without altering the property. While installing smart thermostats usually requires permission, smaller devices can still help manage energy more efficiently.


11. Simple Energy-Saving Changes Renters Can Make Without Permission

Tenants can make small changes that add up, such as:

  • Using draft stoppers on doors
  • Adding thermal or block-out curtains
  • Switching appliances off at the wall
  • Using energy-efficient power boards

These low-cost fixes can noticeably reduce power bills.


12. Can You Ask for Energy-Efficient Upgrades in an Adelaide Rental?

Yes — and many landlords are open to reasonable requests. Improvements like LED lighting, better window coverings, or minor sealing can benefit both tenants and property owners. A polite, well-explained request is often more successful.


13. Energy Efficiency Standards for Rental Properties in South Australia

While South Australia has minimum housing standards, many energy-efficiency improvements are not yet mandatory. That makes it even more important for tenants to ask questions and assess efficiency before signing a lease.


14. Choosing the Right Energy Plan as an Adelaide Renter

Not all energy plans are the same. Comparing providers, understanding peak and off-peak rates, and choosing plans that suit your usage patterns can save hundreds each year — even in less efficient homes.


15. How to Find Energy-Efficient Rentals in Adelaide

When searching for rentals, look for keywords like solar, split system, insulated, or energy-efficient. During inspections, ask about power bills, appliance age, and heating and cooling. A slightly higher rent may be worth it if energy costs are significantly lower.


Final Thoughts

Finding energy-efficient rentals in Adelaide can make a real difference to your comfort and cost of living. By knowing what to look for and making smart energy choices, tenants can reduce power bills without sacrificing lifestyle — even in older rental homes.

If you’re currently searching for a rental, prioritising energy efficiency could save you money every single month.
