03 Sep Why Is My Electricity Bill So High?
Something feels off when each bill creeps higher, even though you haven’t changed how you live. It’s frustrating, like pouring water into a bucket with a hole. Your electricity bill isn’t just numbers – it’s telling you a story about what’s happening in your home.
Most times, it’s a mix of old habits, sneaky appliances, rising rates, or outdated systems working overtime. The good news is there’s a smarter way forward.
Increased Usage Patterns
Has your house been buzzing with more activity lately? It’s easy to overlook small spikes in usage that build up over the month. These changes might seem minor, but they can tip a once-manageable bill into shock territory fast.
Common usage increases include:
🗹 Working from home setups with computers and monitors running all day
🗹 More people are gaming, streaming, and cooking daily
🗹 New tech devices and appliances
🗹 Extended hours of air conditioning or heating
🗹 Additional lighting during longer indoor hours
Whether you’ve added new technology or shifted to remote work, your power usage naturally climbs. These incremental changes add up quickly over a monthly billing cycle.
Faulty and Aging Appliances
An inefficient air conditioner or an ancient fridge could be quietly draining power like a thirsty hose. At MCH Electrical, we often find broken or outdated systems using far more energy than expected.
Warning signs of energy-draining appliances:
🗹 Air conditioners that run constantly but struggle to cool
🗹 Refrigerators that feel warm on the outside
🗹 Hot water systems that take longer to heat water
🗹 Washing machines or dryers that require multiple cycles
🗹 Faulty thermostats causing heating or cooling to run overtime
Even something like a broken thermostat can push your bill through the ceiling without clear warning signs. These issues develop gradually, making them hard to spot until the bill arrives.
Billing and Meter Issues
If your meter hasn’t been checked in a while or if it’s an old analogue one, errors can sneak in. We’ve seen clients get hit with bills based on estimates or stretched-out billing periods that look much higher than usual.
Potential billing problems include:
🗹 Inaccurate meter readings from faulty equipment
🗹 Estimated bills during periods when meters aren’t read
🗹 Extended billing cycles that capture more usage days
🗹 Smart meter glitches that record incorrect data
🗹 Billing errors from your electricity provider
It’s worth comparing past bills to check consistency. Have your meter inspected if you notice sudden, unexplained increases.
Energy Rate Changes
You may not have noticed, but your provider could’ve raised the tariff or moved you to a new billing structure. We’ve helped many locals review bills when sudden jumps appeared.
Rate changes that affect your bill:
🗹 Increased tariff rates during contract renewals
🗹 Automatic switches to higher-rate plans after contract expiry
🗹 Changes to time-of-use billing structures
🗹 New network charges or government fees
🗹 Seasonal rate adjustments
Whether you’ve slipped onto a time-of-use plan without knowing or defaulted to a high-rate contract, these behind-the-scenes changes matter significantly.
Seasonal and Weather Impacts
Extreme Weather Usage
The Queensland sun is a scorcher, and come winter, the chill settles in hard. Our clients often see bills spike due to heaters in July or air conditioning in January. Plus, with shorter days, lights stay on longer.
Seasonal factors affecting your bill:
🗹 Air conditioning is working overtime during hot Queensland summers
🗹 Heating systems run constantly during the cold winter months
🗹 Extended lighting hours during shorter daylight periods
🗹 Humidity control systems are working harder
🗹 Pool pumps and filters are running longer during the swimming season
Weather Abnormalities
A summer that’s more humid or a colder-than-usual winter can throw efficiency out the window. Appliances work harder during extreme temperature changes. Even small shifts in humidity can affect how much your air-con or dehumidifier runs throughout the day.
Holiday and Guest Periods
Hosting friends or family can be heartwarming, but it also adds to your electricity load. More showers, more cooked meals, and devices charging all contribute. These short bursts can trigger a surprising rise in your bill for just one month.
Additional usage during busy periods includes:
🗹 Extra hot water for additional showers and baths
🗹 Increased cooking and kitchen appliance usage
🗹 More devices are charging simultaneously
🗹 Additional laundry loads from extra bedding and towels
🗹 Extended entertainment system usage
Solar Power System Issues
Poor Solar Performance
If your solar system isn’t doing its job, your bill will show it immediately. A damaged inverter or shading from overgrown trees lowers output fast. We’ve seen panels generate less than half their expected energy due to build-up or defects.
Common solar performance problems:
🗹 Inverter malfunctions, reducing power conversion
🗹 Panel shading from trees, buildings, or debris
🗹 Dirt and dust build-up block sunlight
🗹 Faulty wiring connections
🗹 System component failures
Our team checks these issues as part of inspections across the Gold Coast.
Feed-in Tariff Confusion
Feed-in credits can be confusing. If you’re using power during peak hours but generating during low-use times, your credits may not cover what you expect. Some customers were shocked when their credits fell short.
It all comes down to timing – when you use versus when you generate power:
🗹 Peak usage hours when solar isn’t producing
🗹 Low feed-in rates compared to purchase rates
🗹 Misaligned usage patterns with solar generation
🗹 Seasonal variations in solar output
Post-Solar Bill Analysis
If bills remain high after installing solar, it’s time for a proper review. We help clients compare their old and new bills to see if solar gave the expected return. Sometimes, extra tools like battery storage or time-of-use alignment are needed to truly benefit.
Household and Home Factors
Occupancy Changes
The more people at home, the faster the kilowatts add up. Whether it’s a new baby, guests staying over, or teens glued to devices, every added person increases demand.
Our clients commonly notice this shift first in their weekend consumption patterns:
🗹 More people are working or studying from home
🗹 Teenagers with multiple devices and gaming systems
🗹 Extended family members moving in
🗹 Home-based businesses are increasing daytime usage
Home Size and Layout
Larger homes with multiple floors struggle to stay evenly heated or cooled. Zoned systems help, but if someone’s always adjusting the temperature in each room, your energy increases fast.
Queensland homes especially suffer in summer when cooling larger areas:
🗹 Multi-story homes with poor insulation
🗹 Open-plan designs that are hard to zone effectively
🗹 Rooms with poor airflow require individual climate control
🗹 Large windows and glass doors increase heat transfer
Always-On Devices and Lighting
Switching to LED is more than a trend – it cuts power use drastically. Halogen globes and devices left on standby still use energy every hour.
Energy wasters in most homes include:
🗹 Old halogen downlights throughout the house
🗹 Entertainment systems in standby mode
🗹 Phone chargers and power adapters left plugged in
🗹 Computers and monitors never fully shut down
🗹 The pool equipment is running unnecessary hours
At MCH Electrical, we’ve saved families hundreds annually just by installing LED lighting and timers or smart strips.
Energy Efficiency Solutions
Simple Behavioral Changes
Small adjustments to daily habits can make a big impact on your electricity bill:
🗹 Turn off lights when leaving rooms
🗹 Run washing machines and dishwashers only when full
🗹 Cut standby power at night using power boards
🗹 Use timers for pool pumps and outdoor lighting
🗹 Take advantage of off-peak electricity hours
Our clients who started using timers and took advantage of off-peak times noticed bills dropping within one cycle.
Appliance and Home Upgrades
Energy-rated appliances and solid insulation can halve what you spend on cooling and heating:
🗹 Smart thermostats for precise temperature control
🗹 Ceiling fans to reduce air conditioning dependence
🗹 LED lighting throughout the home
🗹 Energy-efficient appliances with high star ratings
🗹 Improved insulation in walls and ceilings
We install these solutions across Queensland homes for quick savings. Ceiling fans alone cut air-con use drastically during the summer months.

🗹 Inefficient systems and equipment
🗹 Opportunities for immediate savings
🗹 Long-term upgrade recommendations
This is the best first step for predictable, lower electricity bills.
