Why Your Assessor Needs So Much Detail on Your Plans

When you’re ready to finalise your BASIX or Whole of Home assessment, it can feel frustrating to hear that your assessor still needs a few more details on your plans. Ceiling fans, insulation types, window glazing, appliance selections — it can seem like overkill.But there’s a good reason for it.

It’s not about being difficult, it’s about accreditation

Accredited assessors operate under strict compliance frameworks. That means every certificate we issue, whether it’s BASIX, NatHERS, or Whole of Home, must directly align with what’s shown on your approved plans and specifications.If your assessment says you’re including ceiling fans or upgraded glazing, that information must appear on the plans before we can legally stamp and finalise your documentation.

It’s not just good practice; it’s a requirement of our accreditation bodies such as Design Matters National. If we stamp a set of plans that doesn’t match the certified documentation, it can trigger compliance penalties or even jeopardise our accreditation.

Consistency protects everyone

Think of it as quality assurance for your project.When your certificate and your plans tell the same story, you have a clear, traceable record of your building’s thermal performance and sustainability measures. It means no last-minute confusion at construction stage and fewer delays during approvals.

It also protects you if your project is ever audited because your documentation will show a consistent, compliant record of what was approved.

The simple way to avoid delays

The best way to keep things moving smoothly is to talk to your assessor early.Before finalising your design, confirm what needs to be shown on the drawings, whether that’s ceiling fans, insulation specs, or appliance upgrades. Once you’ve agreed on the inclusions, add a simple specification table to your plans.

Having everything in one place saves endless back-and-forth and ensures your assessor can issue your certificate quickly and confidently.
