The 5 best expert tips to slash your summer energy bill


Nobody wants their summer ruined by a nasty energy bill. These tips will help you avoid just that.

Around 29% of Aussies are stressed about their energy bills compared to 19% in March, according to Finder's Consumer Sentiment Tracker.

With energy prices predicted to climb a further 35% by 2023, you'll need to do everything within your control to navigate rising costs.

1. That starts by comparing your energy plans

You want to make sure you're getting the best price for electricity. The end of the year is the best time to review your plan and make a switch.

In some states, the difference between the cheapest and most expensive plans is $200–$300 per year.

2. Keep your thermostat at a cool 25 degrees

It might be tempting to blast your air conditioner at 18 degrees when it's scorching hot outside.

However, every degree can add 10% to your running costs.

A general rule of thumb is to keep your thermostat at 25 degrees to avoid blowing up your energy bill.

Given temperatures can vary between states, here's a look at ideal temperature settings based on where you live.

3. Invest in a decent fan

Buying a powerful fan can help you sleep through the night without running the aircon for 7 or 8 hours straight.

It can make even the sunnier days more bearable by providing good ventilation.

I bought a very good $39 Kmart pedestal fan and a summer duvet. I'll admit it's a bit noisy but after a couple of nights, you won't even notice. Before sleeping, I keep the fan running and set my aircon timer to switch off after an hour. This works like a charm.

4. Hack your home and switch to energy-efficient appliances

Heating and cooling can make up 40% of your energy bill.

Reverse-cycle air conditioners are the most cost-effective. The better their energy star rating, the lower your bills will be.

Just make sure it's the right size. For example, a 2.5kW system may not be ideal for a big lounge or massive bedroom.

Average costs for running your split system can vary between $140 and $360 depending on its size and where you live.

Keep in mind that these figures are for 3 months and assume you're running the aircon for 6 hours daily.

Apart from this, you should also consider:

  • Closing the curtain or blinds to keep your room cooler
  • Closing all doors when the aircon is switched on
  • Cleaning your aircon filters on the regular
  • Using snake rugs or draught stoppers to trap in cool air

5. Take advantage of energy rebates and concessions

Hundreds of thousands of eligible Aussies seem to be missing out on energy bill concessions worth up to $372 per year, according to a new paper released by the Consumer Policy Research Centre.

Navigate to your state to find out which rebates and concessions you're eligible for and how to apply.

At the end of the day, a little goes a long way given we're all struggling with the cost of living.

Compare cheap electricity, mobile and internet plans to save more going into 2023.
