An energy audit Canberra homeowners book with Your Passivhaus costs $250 and takes around 90 minutes — by the end, you will have a written report identifying exactly where your home is losing energy, how much each problem is costing you annually, and which ACT government grants you can use to fix it. This guide explains what an energy audit involves, why Canberra homes need one more than almost anywhere else in Australia, and what you can expect to find.

What Is an Energy Audit in Canberra?
An energy audit Canberra is a systematic, on-site inspection of your home’s energy performance. A trained assessor visits your property, checks every significant factor that affects how much energy your home consumes, and produces a written report with specific, prioritised recommendations.
The term “energy audit” comes from the commercial and industrial building sector, where detailed energy accounting is a standard compliance requirement. In the residential context — and particularly in Canberra, where homes consume far more energy than the national average due to the city’s extreme climate — an energy audit focuses on the practical: where is energy leaving your home unnecessarily, and what is the most cost-effective way to stop it?
Canberra sits in Climate Zone 7, the coldest zone on the Australian mainland. The average July minimum temperature hovers around 0°C, and the city regularly records the lowest residential energy bills per square metre in Australia when buildings are designed and sealed correctly — but the highest bills when they are not. An energy audit identifies which situation your home is in and what it will take to move it into the efficient column.
Energy Audit vs Home Energy Assessment: Is There a Difference in Canberra?
Not in practice — and understanding this will save you confusion when searching online.
“Energy audit” and “home energy assessment” describe the same service from the same type of provider. The terms are used interchangeably across the ACT, Australia, and internationally. You will also sometimes see “energy efficiency assessment”, “residential energy audit”, or “house energy audit” — all referring to the same on-site inspection process.
At Your Passivhaus, we call our service a home energy assessment, but if you searched for “energy audit Canberra” and found this page, you are looking for exactly the same thing.
The one product that is genuinely different is a NatHERS assessment (National House Energy Rating Scheme). This is a software-modelled star rating for thermal performance — it produces a certificate number required for regulatory compliance (for example, when selling an ACT property above a certain star threshold, or certifying a new build). It is not an improvement guide. Most Canberra homeowners wanting to reduce bills need an energy audit or assessment, not a NatHERS certificate. The two serve completely different purposes.
What Does a Canberra Energy Audit Actually Check?
Your Passivhaus energy audit Canberra covers seven areas of your home — the same seven that passive house building standards identify as the primary drivers of energy performance in a cold-climate dwelling.
1. Air Leakage and Draught Infiltration
Cold air enters and warm air exits through dozens of gaps in a typical Canberra home: around door frames, window reveals, recessed downlights, exhaust fan grilles, cornices, roof penetrations, and wall penetrations for plumbing and electrical conduit. In a 1980s Canberra brick-veneer home, draught infiltration can account for 20 to 30 percent of total heating energy — the equivalent of leaving a window open all winter.
We map every significant leakage point and quantify the impact, so the improvement report shows you exactly which draught sealing jobs have the best return on investment.
2. Ceiling, Wall, and Floor Insulation
We check actual R-values where accessible — ceiling space, subfloor if present, and walls where construction type allows assessment. Most Canberra homes built before 1990 have either no insulation or insulation well below the current NCC 2022 standard of R6.0 in ceilings. Compressed or degraded batts in a ceiling space can perform at 40 percent below their rated value. We check installation quality, not just presence.
3. Windows and Glazing
Single-glazed aluminium-framed windows are the largest heat loss pathway in most pre-2000 Canberra homes after the ceiling space. We assess frame type (aluminium, timber, uPVC), glazing type (single, double, laminated), thermal break presence, seal condition, and orientation — all of which affect the realistic upgrade priority for your property.
4. Heating and Cooling Systems
We assess the type, age, efficiency rating, sizing, and condition of every space conditioning system in the home. A gas ducted heater more than 15 years old can be operating at 70 percent of its original efficiency. An incorrectly sized reverse-cycle system — either too large or too small — runs inefficiently regardless of its star rating. We identify whether your current systems are the right type and size for your home, and whether an upgrade would pay back within a reasonable timeframe.
5. Hot Water System
Hot water typically accounts for 20 to 30 percent of a Canberra household’s total energy consumption. We check system type (gas storage, electric storage, solar, heat pump), age, effective efficiency at current operating conditions, and whether switching to a heat pump hot water system would generate a positive return under current energy prices and ACT rebates.
6. Ventilation
Mechanical ventilation — HRV (heat recovery ventilation) and ERV systems — can significantly improve indoor air quality in well-sealed Canberra homes while recovering 75 to 90 percent of the heat that would otherwise be lost. We check whether your home has mechanical ventilation, whether it is correctly balanced, and whether issues with the system are reducing its effectiveness.
For homes without mechanical ventilation, we assess whether the existing natural ventilation is adequate or whether air quality issues (condensation, mould, CO₂ accumulation) suggest an upgrade is warranted.
7. Actual Energy Bills
We review your actual energy consumption data — 12 months of bills from your energy retailer — to ground our findings in real-world costs rather than theoretical models. This allows us to identify which systems account for what percentage of your total spend, and to verify that our recommended savings estimates are realistic for your household size and usage patterns.
How Much Does an Energy Audit Cost in Canberra?
An energy audit Canberra homeowners book with Your Passivhaus costs $250. This is a fixed price for residential properties of standard scope — a three to four bedroom home with typical systems.
For context, other Canberra energy auditors and assessors typically charge $350 to $500 for a comparable inspection scope. The difference reflects our lower overheads as a specialist passive house consultancy compared to larger commercial auditing operations — not a difference in the quality or thoroughness of the assessment.
See our full home energy assessment cost Canberra guide for a detailed price comparison and breakdown of what $250 includes.
Is the energy audit cost tax deductible?
For owner-occupied homes, no — home energy audit costs are generally not tax deductible in Australia. For investment properties, an energy audit may be deductible as a property management expense. Check with your accountant for advice specific to your situation.
Does the ACT government help cover the cost?
The ACT Sustainable Household Scheme provides zero-interest loans of up to $15,000 for eligible energy efficiency upgrades, but does not directly subsidise the assessment itself. However, our $250 assessment is the essential first step before applying for scheme funding — it identifies which upgrades are eligible, sequences them by return on investment, and gives you the documentation needed to proceed with confidence.
What Will My Energy Audit Find in a Canberra Home?
Every home is different, but based on energy audits across a wide range of Canberra properties, the most common findings are:
Ceiling insulation below R4.0 (found in approximately 70% of pre-1990 homes) Often the highest-impact upgrade. Top-up to R5.1 or R6.0 typically saves $300 to $500 per year and costs $800 to $1,500 fully installed.
Significant draught infiltration around downlights and exhaust fans Professional draught sealing costs $500 to $1,000 and typically saves $200 to $400 per year. Payback: 2 to 3 years.
Gas ducted heating over 12 years old operating below 80% efficiency Replacement with a correctly sized reverse-cycle heat pump system can reduce space conditioning costs by 50 to 70 percent. Eligible for ACT Sustainable Household Scheme zero-interest financing.
Electric storage hot water over 10 years old Switching to a heat pump hot water system typically saves $400 to $600 per year. After ACT rebates, the net cost is often $800 to $1,200. Payback: 2 years or less.
Single-glazed aluminium windows in main living areas Double glazing is the most expensive upgrade but delivers the largest comfort improvement alongside measurable energy savings — particularly relevant in Canberra’s severe winters.
For a typical Canberra home where all four of these issues are present, the total achievable annual saving after implementing recommended upgrades is $1,200 to $1,800 per year.
How Does the ACT Sustainable Household Scheme Connect to Your Energy Audit?
The ACT Sustainable Household Scheme provides eligible Canberra homeowners with zero-interest loans of up to $15,000, repayable over 10 years, for approved energy efficiency upgrades including:
- Heat pump hot water systems
- Reverse-cycle air conditioning and heat pumps
- Solar panel systems
- Battery storage
- Electric vehicle charging infrastructure
- Insulation upgrades
- Double and triple glazed windows
Your Passivhaus is an approved scheme supplier. Our energy audit identifies which upgrades are eligible, in what sequence they should be installed for maximum impact, and provides the written assessment documentation that supports your scheme application.
For homeowners holding a Pensioner Concession Card, Healthcare Card, or Commonwealth Seniors Health Card, additional rebates of up to $5,000 are available under the Home Energy Support program.
The financial case is straightforward: a $250 energy audit Canberra appointment can unlock $15,000 in zero-interest government financing for upgrades that pay for themselves within three to five years.

Frequently Asked Questions
What is an energy audit in Canberra and how long does it take?
An energy audit Canberra is an on-site inspection of your home’s energy performance, covering seven key areas: air leakage, insulation, windows, heating and cooling systems, hot water, ventilation, and energy bills. With Your Passivhaus, the on-site inspection takes 60 to 90 minutes. You receive a written report within 2 to 3 business days, identifying specific issues, annual dollar savings for each fix, and guidance on ACT government funding options.
How much does an energy audit cost in Canberra?
Your Passivhaus charges $250 for a comprehensive residential energy audit Canberra. Other providers typically charge $250 to $500 for a comparable scope. The $250 fee covers the full on-site inspection, written report, and ACT Sustainable Household Scheme guidance. The assessment cost is typically recovered within the first two to three months of implementing the first recommended upgrade.
Is an energy audit the same as a home energy assessment in Canberra?
Yes — “energy audit” and “home energy assessment” describe the same service. The terms are used interchangeably. What is genuinely different is a NatHERS assessment, which produces a regulatory star rating certificate for property sales or new builds, rather than an improvement guide. Most Canberra homeowners wanting to reduce bills need an energy audit or assessment, not a NatHERS certificate.
What does a Canberra energy audit typically find?
The most common findings in Canberra homes are: ceiling insulation below current standards (R4.0 or less), significant draught infiltration around downlights and exhaust fans, ageing gas heating systems operating below 80% efficiency, and electric storage hot water systems approaching end of life. In most pre-1990 Canberra homes, addressing all four issues delivers annual savings of $1,200 to $1,800.
Can I use ACT government funding to pay for an energy audit?
The ACT Sustainable Household Scheme does not directly fund the audit itself, but a $250 Your Passivhaus energy audit is the essential first step for accessing the scheme. The scheme provides up to $15,000 in zero-interest loans for eligible upgrades identified in your assessment. Your Passivhaus is an approved scheme supplier and will guide you through the application process as part of the post-assessment service.
