Why is my energy bill so high?

If you’re a Perth homeowner, there’s a good chance you’ve asked yourself this lately.

Here are the top reasons your energy bill may be high and some easy ways to reduce energy bills.

Key Tips: High Energy Bills in Perth
1. Renovations Impact Bills Home renovations can increase energy usage. Be mindful during these projects.
2. Monitor Hot Water Usage Leaks in hot water systems and extended hot showers can spike bills. Consider efficient showerheads and time limits.
3. Use Appliances Wisely Avoid using ovens for heating; seal windows and doors in summer to ease strain on cooling systems.
4. Seasonal Adjustments Matter Extreme weather leads to increased energy use. Optimize heating and cooling systems during seasonal shifts.
5. Consider External Factors Compare bills to the same period last year. Account for gatherings, guests, or recent moves affecting energy usage.


What Are the Possible Causes of a High Energy Bill?

If your energy bill suddenly seems higher than usual, here are some possible causes.

1. Home Renovations

If you’re in the middle of home renovations, such as a bathroom or kitchen remodel, you’ll probably notice higher energy bills. This is especially true if you have workers on site. The construction process will require more energy than normal.

2. You Are Using More Hot Water

A leaky electrical hot water system can use a surprising amount of energy. If you notice an unexplained spike in your energy bills, you may want to consider having your water heater inspected.

If using more hot water is a case of a family member that favours long showers, consider installing an energy-efficient showerhead to help cut back on some energy usage. Or, consider setting a time limit on hot showers.

3. You Are Using Appliances to Cool or Heat Your House

With our scorching, record-setting Perth summer, heating your home is probably the furthest thing from your mind. Still, your oven should never be used as a source of heat for your home.

In summer, make sure your windows and doors are sufficiently sealed to keep heat out of your home and make it easier to keep it cool with less energy.

4. Seasonal Changes

Anytime the seasons shift, you will likely notice a spike in your energy bills. For instance, as we’ve moved into summer (especially this one!), it is normal to see higher energy bills. We’re guessing your aircon system is working overtime right now.

5. Unfair Comparisons

If you compare your current energy bill to several months ago, it may not be the most reliable way to assess your energy usage.

Rather, compare your bill to a year ago to ensure you are evaluating your current bill based on similar weather conditions. Also, make sure your current bill doesn’t feature a longer billing period than previous statements.

6. Guests

Think back to the previous month. Did you host several get togethers or have visitors staying for a few days? If so, you’ll likely see a higher energy bill for the month.

7. Your Appliances Need Updating

Take a look around your house and make note of how old your washer, dryer, fridge, oven, and dishwasher are.

If your appliances are a decade or older, it may be time for an energy-efficient upgrade. Some newer models of fridges and dishwashers can be 50% more efficient than older versions.

8. You’ve Moved

A new home will certainly feature different energy usage than your last. It will likely have a different heating and cooling system, and different appliances, or may be bigger or smaller than your previous home. All of these changes will amount to differences in your energy bills.


Tips on How to Reduce Energy Bills

If you want to reduce energy bills, there are many easy ways to cut back on your energy consumption. Some of these tips may seem too easy to make much of a difference but you’ll be surprised at how helpful they can be.

Here are the best tips on how to reduce energy bills and save money every month:

  • Open curtains, blinds, and windows in the cooler months to let in sunshine and take advantage of some natural heat
  • Invest in high-quality shades or blinds and pull them down during the hottest time of day in summer
  • When heating or cooling rooms, focus on areas you spend the most time (i.e. bedrooms or living room)
  • Wear weather-appropriate clothing, such as cosy layers in the winter months and cooler clothes in the summer
  • Don’t go overboard with heating or cooling your home. You can stay comfortable without going too extreme in either direction. We find that 19°C in winter and 24°C are comfortable temps that aren’t as taxing on heating and cooling systems
  • Check your hot water thermostat and find the most energy-efficient setting (usually this is around 60ºC)
  • If you are travelling, you may want to consider turning off your hot water system to save energy (before doing this, check the manufacturer’s recommendations and set a reminder to make sure you turn it back on once you arrive back home)
  • If your hot water system is equipped with a timer, set it to maintain a lower temperature during times of the day you know you won’t be using it
  • Run your dishwasher using cold water
  • Limit the amount of time you spend in the shower
  • Upgrade any old appliances and opt for models with high Energy Star ratings
  • Set your fridge and freezer at energy-efficient temperatures (for a fridge, this is around 3° to 5°C and a good temperature for a freezer is typically -15° to -18°C)
  • Wait until your dishwasher and washing machine are completely full before running them (check to see if your washing machine or dishwasher has an economy cycle)
  • Make sure your cooling and heating systems are properly sized to ensure they aren’t working harder than they need to
  • Run your aircon system on eco-mode and make sure to cool or warm your house slowly as this requires less energy than forcing it to quickly change temperatures
  • Use a rolled up towel or door snake to seal the area under your doors
  • Schedule professional maintenance for your electrical systems to ensure everything is working as it should
  • Have your heater and air-conditioner professionally serviced to make sure they are running efficiently
