Why is my electricity bill unexpectedly high and how can I investigate the reasons?

High electricity bills can be concerning, especially when your usage habits don’t seem to align with the charges. Below, we address the common causes of unusually high electricity bills and provide actionable steps to understand and potentially reduce your energy costs.


Common Causes of High Electricity Bills

1. Seasonal Factors

Electricity usage often increases during colder months (e.g., winter) due to:

  • Heating systems running more frequently

  • Longer or hotter showers

  • Lights being used for extended periods due to reduced daylight Even if you haven’t changed your habits, these seasonal needs can significantly impact your energy consumption.

2. Faulty or Old Appliances

Malfunctioning or outdated appliances, such as water heaters, refrigerators, or electric heaters, may consume excessive energy. Frequently used devices, or new additions like electric vehicle chargers, can also contribute.

3. Unnoticed Constant Usage

Leaving appliances or devices running while your property is vacant (e.g., pool pumps, plugged-in devices) can lead to higher bills even when the property is unoccupied.

4. Extended Billing Periods

Sometimes, an invoice covers more days than usual, leading to higher overall charges.


How to Investigate High Bills

If you believe your electricity bill is higher than expected without clear reasons, here are steps to investigate:

1. Check Appliance Efficiency and Usage

  • Inspect Older Appliances: Have an electrician assess potentially faulty devices, especially high-consumption items like water cylinders.

  • Perform a Load Test: Isolate and measure individual appliance usage by turning off all devices and switching them back on sequentially. This can help identify unusually high consumption.

2. Verify Your Meter and Billing Information

  • Confirm Meter Accuracy: If you suspect inaccuracies, provide a photo of your meter to us for verification. Smart meters generally provide accurate readings.

  • Review Billing Periods: Cross-check the duration of your billing cycle to rule out extended periods as the cause of higher charges.

3. Consult with us via live chat

  • Ask for a breakdown of your energy usage.


Tips to Avoid Future High Bills

  • Unplug Unused Devices: Even when not in use, plugged-in appliances and chargers can draw power (phantom loads).

  • Optimize Heating Systems: Set your heat pump to an efficient temperature and use timers or programmable settings.

  • Schedule Regular Appliance Maintenance: Ensure that all major devices are working efficiently and without defects.


Understanding Your Responsibility as a Customer

1. Daily Line Charges

Daily line charges are fixed costs for maintaining electricity meters and services in your area. These charges apply even if the property is unoccupied.

2. Rate Increases

Like all companies, we sometimes may adjust your rates. Be mindful of these changes and consult us if you notice discrepancies.

3. Meter Disconnection Policies

For properties transitioning between tenants, providers may intentionally leave meters connected to prevent service interruptions. If however, your account remains active by mistake, additional charges may occur.


High electricity bills can stem from multiple factors ranging from weather and appliance usage to billing policies and fixed charges. By understanding these causes and investigating usage anomalies, you can take steps to optimize energy consumption and resolve billing concerns efficiently.
