What is the cost and timeline for obtaining a Section J Report?

Short answer

Costs generally range from AUD 1,200 to AUD 4,000 depending on building size and complexity. Timelines can range from 48 hours (express service) up to a couple of weeks depending on design maturity and work required.

Full answer

The cost of a Section J Report depends on multiple variables: size and floor area of your building, complexity of building form, how much modelling is required, whether JV3 is used, complexity of glazing, number of zones, etc. Basic DtS compliance with straightforward design will be at the lower end; more complex or performance‑based methods incur higher costs.

As for timeline, at Certified Energy you can often get standard reports within a few days once all required architectural plans, specifications and design inputs (insulation, glazing etc) are supplied. For urgent projects we offer an express service (48‑hour turnaround) for an additional cost. Delays usually occur if documentation is incomplete or design changes are happening during the report process.

Why this matters

Understanding how long a Section J Report will take is essential for effective project scheduling, as it allows you to integrate compliance into your design and approval timeline without unexpected delays. It also supports better cost management by helping you budget accurately and avoid surprise fees. Providing complete and accurate design documentation early in the process reduces the risk of rework, speeds up report preparation and helps prevent cost escalations later in the project.

How Certified Energy can help

At Certified Energy, we provide a fixed‑fee quote once you supply your plans and specifications, giving you cost certainty from the outset. If your project is time-sensitive, we offer express turnaround options, including a 48‑hour service. We also guide you on the documentation required so you can prepare everything in advance, helping to streamline the process. With experience across a wide range of projects, we ensure our time estimates are realistic, reducing the risk of unexpected delays or last‑minute issues.
