How to Reduce Electricity Bills in Rental Homes

If you own the property, you can upgrade appliances, install solar systems, improve insulation, or change electrical infrastructure. As a tenant, those decisions sit with the property owner, so your focus shifts to how electricity is used through daily habits. In Australia, rental agreements limit changes to electrical systems, and any upgrades need approval from the property manager and property owner. This guide explains practical steps to manage electricity through appliance use and general household routines.

What Drives High Electricity Costs in Rental Properties

Electricity costs in rental homes rise when several systems draw power across the day. Below shows where most electricity use comes from and how it builds up.

Source of Electricity Use	Cost Factors
Heating and cooling	Long run times, frequent temperature changes, and systems working harder during peak weather.
Hot water use	Repeated heating cycles from showers, and taps throughout the day
Appliances	Regular use of washing machines, dryers, ovens, and kitchen equipment across daily routines
Refrigeration	Continuous operation that runs all day to maintain cooling inside the fridge and freezer
Standby power	Electronics left plugged in that draw small amounts of electricity even when not in use
Lighting	Lights left on in unused rooms or used longer than needed during the day and night

These areas combine across daily routines and build up into higher electricity bills. Below are practical ways to reduce this usage through simple changes in your daily power habits.

Reduce heating and cooling use at home

Heating and cooling systems place the highest demand on electricity in rental homes. Bills rise when systems run for long periods or when temperatures are adjusted too often throughout the day.

→ Set temperature at a steady level

→ Close doors and windows while systems are running

→ Use fans to support airflow before adjusting settings

→ Keep curtains closed during strong sun exposure

If airflow is uneven between rooms, report it through your property manager so it can be checked.

Lower hot water consumption daily

In storage systems, the water is kept warm at a set temperature and reheats when it cools down. Every time you use it, cold water enters the system and must be reheated, which increases electricity.

→ Keep showers short and consistent

→ Turn off taps during shaving or washing

→ Check for dripping taps that add constant demand

Changes in water temperature or slower recovery times may also indicate increased system load.

Lower washing machine and dryer use 

Laundry appliances use electricity based on cycle length, load size, and settings. Running small loads increases total energy use.

→ Run full loads instead of small cycles

→ Use cold wash settings for regular clothing

→ Select shorter wash programs where suitable

→ Limit dryer use for larger loads only

Air drying clothes reduces reliance on dryers, which use higher energy due to heat generation during operation.

Optimize fridge and freezer operation 

Refrigeration systems run continuously through a compressor that switches on and off throughout the day to keep the internal temperature stable. When cold air escapes through gaps, the compressor runs longer to bring the temperature back down. This repeated cycling is what increases electricity, even when the fridge is not actively used.

Do not overload shelves so air can circulate properly and close door seals firmly without gaps. Unusual noise or temperature changes may signal increased running time and should be checked.

Switch off appliances when not in use

Many appliances still keep electrical parts active while plugged in, such as remote sensors, clock displays, internal circuits, update settings, and quick-start functions.

→ Switch off devices when not needed

→ Use power boards to turn off several devices

→ Unplug chargers once devices are fully charged

→ Turn off ovens, fans, and heaters once the task is done

→ Avoid leaving appliances running in empty rooms

One appliance may not add much, but several plugged-in devices running this way every day adds cost to your electricity bill.

Switch to LED bulbs

LED bulbs use around 5–15W and are more efficient than older halogen systems while also offering additional benefits:

→ Uses up to 75% less energy than halogen lighting

→ Produces up to 90% less CO₂ emissions compared to halogens

→ Lasts up to 25 times longer, reducing replacement and maintenance needs

→ Produces less heat, which can reduce air conditioning demand

→ Does not contain mercury, unlike CFL lighting options

LED quality can vary, so it’s best to choose reputable, name-brand products for better performance and reliability.

Common Everyday Habits That Increase Electricity Use  

Most tenants assume these daily habits are normal, but they quietly add extra usage across the day without much attention. Common habits that add to electricity use include:

→ Leaving devices on standby for long periods

→ Running half-load laundry cycles

→ Using heating or cooling with doors open

→ Leaving lights on in empty rooms

→ Changing temperature settings frequently

Being aware of these habits helps you make simple adjustments during daily routines and gives you more control over your monthly electricity bills.

Why Energy Systems Sit With Property Owners

Energy systems in rental homes are managed by the property owner, involving installation and system design while tenants operate within the existing setup and focus on how electricity is used. This also extends to broader energy upgrades:

→ Solar systems and energy storage

→ Property-level system upgrades and replacements

→ Long-term energy planning decisions

In some cases, planning may include the cost of solar batteries, which relates to how energy is stored and managed across the property.

Awareness Helps Reduce Electricity Waste in Rentals 

Awareness works best when everyone in the household takes part. When each person switches off lights, avoids leaving devices running, and uses appliances with care, electricity use stays more balanced. Shared responsibility keeps electricity costs manageable without affecting comfort at home.
