Experienced BASIX Consultants & NatHERS Assessors
Assessify is a Sydney‑based team of experienced BASIX consultants and NatHERS assessors, helping homeowners, builders, architects, and designers achieve fast, accurate BASIX compliance across NSW.
With deep construction knowledge and accredited energy modelling expertise, we make BASIX certificates and NatHERS reports simple, clear, and stress‑free.
With over 25 years of combined experience in construction and building performance, we understand the real‑world challenges of delivering compliant homes without blowing budgets or delaying approvals. Our role as BASIX consultants is not just to pass assessments, but to help projects move forward smoothly with practical, buildable solutions.
Our Experience as BASIX Consultants
Our background in construction gives us a practical edge as BASIX compliance consultants. We understand how design decisions, material selections, and construction methods impact energy, water, and thermal performance — and how those choices affect cost, buildability, and approvals.
As accredited BASIX consultants and NatHERS assessors, we work across:
- New homes and custom builds
- Alterations and additions
- Granny flats and secondary dwellings
- Dual occupancies and multi‑dwelling developments
We deliver BASIX certificates for projects throughout Sydney and regional NSW, with a strong understanding of local council expectations and approval processes.
Our Promise
Our promise as trusted BASIX consultants in NSW is built on three core principles:
Accuracy
Every BASIX certificate and NatHERS report is completed using accredited software and current best‑practice methodologies, ensuring your documentation is correct the first time.
Speed
We provide fast turnaround times for BASIX requirements and NatHERS assessments, helping you meet tight DA and CDC deadlines without unnecessary back‑and‑forth.
Clarity
Our BASIX reports and NatHERS certificates are builder‑friendly, certifier‑ready, and easy to understand — reducing confusion, RFIs, and construction delays.

- Architects & Designers – preserving design intent while achieving compliance
- Builders & Developers – identifying cost‑effective solutions and avoiding overspecification
