Electricity bills in Melbourne have never been higher – and for many households, energy costs are one of the biggest items in the monthly budget. The good news is that there’s a lot you can do about it.
Whether you’re looking for quick wins or bigger long-term investments, this guide covers the most effective ways to reduce your electricity bill in 2026 — backed by the expertise of O'Brien Electrical & Plumbing Rowville’s team of electricians and plumbers.
Solar remains the single most impactful thing most Melbourne homeowners can do to slash their electricity bills. A well-sized solar system generates free electricity during the day, reducing how much you draw from the grid when rates are at their highest.
With the Solar Victoria rebate of up to $1,400 and the federal STC discount also applying, the upfront cost of going solar in 2026 is lower than it’s ever been. Most households see payback within 4–7 years, with the system continuing to generate savings for 20+ years after that.
Solar panels generate most of their electricity during the middle of the day, when many households aren’t home to use it. A home battery stores that excess energy and releases it in the evening when grid electricity is most expensive.
With Victoria’s peak electricity rates sitting at 40–55 cents per kWh, a 10kWh battery can save a typical Melbourne household $80–$120 per month through smarter energy use. The federal Cheaper Home Batteries Program provides a significant upfront discount on battery installation – check with your installer for current rebate amounts.
3. Upgrade to a Heat Pump Hot Water System
Hot water is one of the biggest energy costs in any home, typically accounting for 20–25% of a household’s energy bill. Switching from a conventional electric or gas hot water system to a heat pump can reduce your hot water energy use by up to 80%.
Heat pumps extract warmth from the surrounding air to heat water – a far more efficient process than generating heat directly. Combined with solar panels, they can run for almost nothing during the day. Victorian government rebates of up to $1,400 are currently available to eligible households.
4. Switch to LED Lighting Throughout Your Home
If your home still has halogen downlights or older fluorescent fittings, upgrading to LED lighting is one of the quickest and most cost-effective changes you can make. LED lights use up to 75% less energy than halogens and last many times longer – meaning lower bills and fewer bulb replacements.
A full LED lighting upgrade across a typical Melbourne home can save hundreds of dollars per year. The Victorian Energy Upgrades (VEU) program may provide additional discounts on LED upgrades through accredited suppliers.
5. Install an EV Charger and Charge on Solar
If you own or are considering an electric vehicle, installing a home EV charger and pairing it with solar is one of the most effective ways to reduce your total household energy spend. A smart EV charger can be configured to charge your car during peak solar production hours, meaning you’re powering your vehicle for free rather than paying grid rates.
With petrol prices remaining high, the combined savings on fuel and electricity can be substantial for households making the switch to EVs.
Heating and cooling accounts for around 40% of energy use in Australian homes. If your ducted gas heating system or older split system is due for replacement, upgrading to a modern, energy-efficient reverse cycle system can make a significant difference.
Modern reverse cycle air conditioners are far more efficient than older models, with some achieving a coefficient of performance (COP) of 4 or above – meaning they generate 4 units of heating or cooling for every 1 unit of electricity consumed. The VEU program may also provide rebates on eligible heating and cooling upgrades.
7. Use a Smart Home System to Manage Energy Use
Home automation technology allows you to intelligently manage your home’s energy use – automatically running high-draw appliances during solar peak times, scheduling heating and cooling to pre-condition your home efficiently, and monitoring your consumption in real time through a smartphone app.
O'Brien Electrical & Plumbing Rowville can design and install a home automation system tailored to your energy goals, integrating solar, batteries, lighting, and climate control into a single, easy-to-manage platform.
