Section J Compliance Estimator

Get an indicative assessment of whether your commercial building project is likely to meet NCC Section J energy efficiency requirements.

Step 1 of 3
Building Classification
Section J applies to Class 3 to Class 9 buildings under the NCC. Select the classification that best describes your project.
Building Envelope
The envelope (walls, roof, glazing) is a major factor in Section J compliance. Tell us about the primary construction.
Building Services
HVAC, lighting, and hot water systems all contribute to Section J compliance.
Your Section J Compliance Outlook
This estimator provides a high-level indication only. Actual Section J compliance requires detailed assessment against NCC 2022 Volume One, Part J, including thermal modelling (JV3) or Deemed-to-Satisfy verification. Project-specific factors such as building orientation, shading, services design, and local climate zone all affect the outcome.
Need a Section J report?
Our commercial team prepares Section J reports for projects of all sizes. We can also advise on JV3 verification if DTS compliance is difficult to achieve.
