NatHERS for Existing Homes: What Every New Homes Assessor Needs to Know
NatHERS now rates existing homes too, and your new homes accreditation does not carry across.
NatHERS now runs two streams side by side. See how rating a home that already stands differs from rating one on paper, how the staged accreditation pathway and the Scorecard transition work, what disclosure policy means for demand, and how to prepare your workflow, records and client conversations if you decide to move into existing homes work.
Secure card checkout. Tax invoice emailed.
4 modules, 2 case studies, final quiz and certificate.
Introduction and objectives
Who the existing homes stream is for, why the timing matters to your practice, and the four things you will be able to do by the end.
Two Streams, One Framework
Tell the new homes and existing homes streams apart: the tools, the site visit, and the data you collect when there are no specifications.
Accreditation Pathways and Timing
Follow the staged accreditation pathway and the training route, and see what the Scorecard closure means for assessors already doing site work.
The Commercial Opportunity
Weigh the demand that disclosure policy is creating against the small pool of accredited assessors, and model what the work is worth.
Preparing Your Practice
Adapt your workflow for site work, separate observed from assumed data in your records, and set clear expectations with homeowners.
Case Studies
A new homes assessor working through the Stage 2 pathway, and a Scorecard assessor moving clients across to NatHERS existing homes.
Summary and Key Takeaways
The decision points to take back to your practice.
Final quiz and certificate
Ten questions. Pass and the certificate goes straight into your dashboard.
Intermediate. For accredited NatHERS assessors who work on new homes and want to understand the existing homes stream before deciding whether to move into it. Covers the two streams, the staged accreditation pathway, the Scorecard transition, the commercial case and practice preparation. It is not the accreditation training itself, and it reflects information published by February 2026, so confirm current dates with the NatHERS administrator.
Written for the people deciding whether existing homes work belongs in their practice.
Energy assessors
You rate new homes from plans, and you are weighing whether to add site based existing homes work to your practice.
Architects
Renovation clients will arrive with an existing home rating, and you need to know what it measured and what it assumed.
Building designers
An existing home rating tells you where an extension or upgrade starts from, if you know how it was produced.
Residential builders
Ratings are starting to shape renovation decisions, and homeowners will ask what an upgrade does to theirs.
Building surveyors
You need to tell a compliance rating on a new home from an advisory rating on an existing one.
