Top 5 home upgrades that can cut your energy bills in 2026

Energy costs continue to fluctuate across Australia, resulting in bill shock when the quarter ends and the bills roll in.

What if taking a few simple steps could help not only control energy costs but also lower them?

That's the reality for homeowners across the country who are taking advantage of government rebates to install solar panels and heat pump hot water systems.

A typical Victorian home transitioning from complete grid reliance to independence can expect to save between $2000 and $5000 a year depending on the usage and home size. Adding batteries and improving home insulation further enhances the long-term savings.

On average, a heat pump hot water system saves about $800 a year, reverse-cycle heating and cooling can save between $1500 and $2000 a year and adding solar panels can reduce bills by up to $1500 to $5000 annually.

"More importantly, households often gain predictability in energy costs, which has become increasingly valuable as prices fluctuate," Carbon Savers operations manager Reno Damianou said.

With extensive experience helping households transition from gas-dependent homes to efficient all-electric energy systems across Victoria, Reno offers his top five upgrades that can cut power bills in 2026.

"Planning upgrades as part of a whole-home electrification strategy usually delivers better financial outcomes," he said.

Solar reduces daytime grid electricity use and protects households from rising energy prices.

Typical cost: $4000 to $8000 after STC rebate (for a typical 6.6 kW residential system)

Typical savings: $1500 to $5000 annually

Return on investment: Three to five years

Batteries allow households to store solar energy and use it in the evening, giving you energy independence from your energy retailer and reducing reliance on the grid.

Many systems now integrate directly with solar monitoring apps, allowing households to track usage in real time.

Typical cost: $8000 to $30,000 after federal rebate

(depending heavily on battery size and installation complexity)

Typical Savings: $1500 - $3000 a year

Typical Return on Investment: Three to five years

Heating is one of the biggest energy costs in Victorian homes, particularly in regional areas. Modern reverse-cycle systems are significantly more efficient than gas heaters or older electric systems.

Typical cost: $2000 to $3000 per unit installed (split system) or $8000 to $15,000+ installed (ducted)

Typical savings: $1500 to $2000 a year

Typical Return on investment: Three to six years

Hot water typically accounts for around a quarter of household energy use. Replacing an electric storage or gas system with a heat pump can reduce water-heating energy use by up to 80 per cent.

Heat pump technology has improved significantly over the past 24 months, with quieter operation, better cold-weather performance, and smarter controls.

Typical cost: $1500 to $4000 after rebates

Typical savings: $800 a year

Typical return on investment: Two to three years

Often overlooked, improving insulation can dramatically reduce heating demand and improve comfort. This includes double glazing on windows and glass doors, insulation in walls and ceilings and window and door seals.

If costs seem prohibitive, contact experts to talk through what savings you could be looking at with the upgrades and what government rebates are available.

"Depending on rebate amounts, if they are generous at the point of purchase, payment plans can be considered to take advantage of the savings. But talk to a specialist in this space, sometimes monthly bill savings outweigh the monthly repayments," Reno said.

One of the biggest mistakes households make is leaving too much time between upgrades and missing the most generous rebates.

"People will install solar one year, then wait several years before looking at hot water or heating, only to find the rebates have dropped or closed," he said.

"If incentives are strong, it's worth planning a bundle of upgrades so you can lock in the available support while it lasts."

Victorian households considering upgrades can seek tailored advice from energy specialists such as Carbon Savers to assess eligibility, system suitability and projected savings before committing.
