Know what the next step needs before committing
Check urgent-replacement evidence, owner or strata permissions, renter-friendly boundaries and what each budget band should accomplish.
Open the project preparation guideFind the right evidence without opening ten tabs
Start with the decision you are making. Each guide explains what to check, what belongs in a written quote and which official source should confirm incentives or requirements.
Not sure which guide comes first?
Build a private home energy roadmap from your goal, property situation and existing equipment. It puts the relevant comparisons, guides, assessment and project brief in order.
What are STCs, VEECs and other energy certificates worth?
Learn what each certificate represents, which ones can affect household upgrade discounts and how indicative reported prices have moved over the past six months.
Need a NatHERS or BASIX assessment?
Start with the dedicated assessment hub for new homes, existing homes and NSW BASIX projects, including the evidence to prepare and the official pathway to confirm.
Choose a guide
Start with the decision you are making
Work out what to improve first
Start with safety, comfort and the building itself, then plan equipment, electrification, solar and batteries around your home.
Open the home energy upgrades guideGet ready without collecting the wrong paperwork
See what to prepare for plan-based NatHERS work, an on-site Home Energy Rating or a general energy audit.
Open the assessment checklistCheck whether a free program really applies
Learn what is free, what still needs a quote and how to verify a current council or government offer.
Open the assessment cost guideGet clear answers about ratings, bills and savings
Separate what an assessment can show from what depends on your home, household and approval authority.
Open the myths and facts guideUnderstand NCC, NatHERS and BASIX
See which system sets the rules, which one models the home and how NSW BASIX fits into the approval process.
Open the NCC, NatHERS and BASIX guideKnow what a green building claim really means
Compare NCC, NatHERS, BASIX, Home Energy Rating, Green Star and NABERS without treating their labels or star scales as interchangeable.
Open the ratings and certifications guideMatch generation to your home
Understand sizing, self-consumption, exports, site design, quote assumptions and installer checks.
Open the solar guideTest whether storage fits your load
Understand usable capacity, power, backup, cycling, warranties, VPP terms and the current federal discount structure.
Open the battery guideReduce the load before sizing equipment
Compare reverse-cycle systems using climate-zone performance, room needs, noise, installation details and realistic operating patterns.
Open the heating guideCompare the right system for the job
Understand reverse-cycle air conditioners and heat pump hot-water systems, including sizing, climate, noise and quote checks.
Open the heat pump guideMatch the system to household demand
Compare heat pump, solar, storage and continuous-flow options using capacity, climate, tariffs, noise, backup and written quote evidence.
Open the hot water guideReduce unwanted heat flow and air leakage
Assess insulation, draughts, ventilation, moisture, windows, safety and quote scope before replacing major heating or cooling equipment.
Open the insulation guideCoordinate the appliance and enabling work
Check induction cooking, cookware, circuits, ventilation, kitchen fit and safe gas decommissioning.
Open the cooking guideMatch charging power to real driving
Check daily range, parking, solar, tariffs, switchboard capacity, smart controls and strata approval.
Open the EV charging guideUse your own load pattern where possible
A household can use the same annual electricity as another home but at very different times. Half-hour meter data makes solar self-use and battery discharge estimates more representative.
Check location-specific support
Rebates, certificates, loans and provider discounts can have different rules. Choose your state or territory and confirm the official source before using an incentive in a quote.
Need a reliable starting point for supplier research?
Use the independent government and community sources, then check the licence, product, scope, warranty and rebate evidence for the exact work.
See why the evidence matters
Worked examples show how timing, self-use and seasonal consumption can change an assessment, with the method and limitations visible.
