The most useful way to lower an electricity bill is to find where energy is being used and choose changes that fit the property. Lighting, heating, cooling, hot water and appliance use deserve attention before assuming new wiring or a switchboard will reduce consumption.
An electrical safety upgrade can be worthwhile without producing a bill saving. Keep those two decisions separate when comparing work.
1. Review the lighting
If you still use halogen or incandescent bulbs, suitable LEDs can reduce lighting energy use. The Australian Government lighting guide (opens in new tab) says LEDs use about 75% less energy than halogen bulbs and last 5–10 times longer.
Your saving depends on the actual fittings and hours of use. Start with lights used frequently, such as the kitchen, living areas or business display lighting. A fitting used occasionally will contribute less to the bill.
AB Electrical's lighting service covers compatible fittings, dimmers and controls. Fixed-wiring changes need an electrician.
2. Put controls where they help
Timers, sensors and separate lighting zones can reduce the time equipment runs unnecessarily. Think about:
- Lights left on in empty rooms or after a business closes.
- Outdoor lighting that runs longer than needed.
- Areas where separate switches would avoid lighting the whole space.
- Controls that are difficult to use or do not match occupancy.
Choose controls around how the space is used. A sensor that keeps switching lighting on unnecessarily may not deliver the expected benefit.
3. Treat outlets and switchboards as safety and capacity decisions
Damaged outlets and unsuitable circuit protection need attention, but replacing them does not automatically reduce electricity use.
Extra powerpoints can improve convenience and reduce reliance on extension leads. They do not reduce the power drawn by the appliances plugged into them. USB outlets are also not automatically more efficient than a suitable plug-in charger.
Similarly, a switchboard upgrade may improve protection or accommodate new circuits. Ask for the safety and capacity reasons for the work rather than expecting the board itself to lower the bill.
4. Check avoidable appliance use
Useful checks include:
- Turn off equipment that does not need to remain on, following its instructions.
- Review standby settings where practical, without interrupting essential equipment.
- Check timers against your actual schedule.
- Look for equipment running outside the hours it is needed.
- Compare usage on bills or monitoring tools before and after a change.
Avoid switching off medical, security, refrigeration or other essential equipment without understanding the consequences.
5. Match upgrades to the property
A home office, shop and family home can have very different energy-use patterns. List the equipment used most, its operating hours and the comfort or business requirements it supports.
For planned work, ask what is expected to reduce consumption, what improves usability and what is needed for safety. A useful proposal makes those benefits clear without treating every electrical job as an energy-saving measure.
6. Review air conditioning and hot water
For air conditioning, the equipment's efficiency, settings, maintenance and suitability for the room affect consumption. An electrical connection needing repair is a safety issue; changing it is not an automatic efficiency upgrade. See the air-conditioning service page for assessment and installation work.
Hot-water costs depend on the system type, hot-water use, settings, losses and tariff. Replacing an ordinary electric element does not inherently make the same heating job use less energy. A controlled-load tariff may change the price paid rather than the amount of energy used. For a fault or proposed replacement, see our hot-water repair and installation service.
The appropriately qualified in-house team can assess electrical, plumbing or refrigeration work relevant to the system. Ask about the full scope and expected benefit before replacing equipment.
7. Fix faults for safety
Flickering lights, repeated tripping, hot outlets and a buzzing switchboard need investigation. They do not provide a reliable estimate of wasted energy or prove that a repair will cut the bill.
Do not touch equipment to check for heat or repeatedly reset a fault. Keep away from damaged equipment and call an electrician. Call 000 for smoke, fire or immediate danger.
How to compare the options
For each proposed change, consider:
- The current energy use and how often the equipment runs.
- The purchase and installation cost.
- Whether the benefit is lower consumption, a different tariff, comfort, safety or convenience.
- Maintenance and replacement requirements.
- How you will check the result using actual usage rather than a promised saving.
That makes it easier to prioritise useful work without expecting every upgrade to pay for itself through the electricity bill.
What to do next
Contact AB Electrical with the suburb, property type and the equipment or rooms you want to review. Mention any faults separately so safety issues can be prioritised.
For a straightforward first step, note when equipment is used and bring a recent bill or usage summary to the discussion. You do not need to guess the technical cause before asking.
For a fault with warning signs, such as a burning smell, heat at an outlet, sparking or repeated tripping, call 0405 343 343 from a safe place rather than folding it into a bill review. For the review itself, send an enquiry with the details above and photos of fittings or equipment only if they can be taken safely.
