Ecovantage STC and Ecovantage vs: how to compare

Written and checked by the Energy Merchants desk · Reviewed 2 October 2026

Ecovantage comes up in two kinds of search: “Ecovantage STC” from installers weighing their options, and “Ecovantage vs” from those comparing it with other providers. This page covers both. It reports what Ecovantage says about itself, flags what it does not publish, and explains why it belongs in a different category from a straightforward certificate buyer. We do not rate it.

What Ecovantage says about itself

According to its website (2 Oct 2026), Ecovantage describes itself as “a certificate creator and project auditing specialist” that works with installers to audit energy projects and “generate and monetise all Australian federal and state energy certificates”. It says it has “over 19 years in business and millions of certificates generated” across energy schemes, and its site offers an STC home battery calculator.

The self-description puts the emphasis on creating and auditing certificates, which is closer to the compliance and creation end of the market than to a pure buyer. How its monetisation works commercially is a question for Ecovantage.

What it does not publish

On the page we read, Ecovantage did not state fees, payment times or rates. That is common for businesses that quote per project. It does mean the comparison has to happen in an email or call rather than on a table of published figures.

“Ecovantage vs” what?

The right comparison depends on what you need.

Against a software platform. If you want to create and manage certificates yourself, look at the platform category; see Formbay alternatives for how one describes itself.

Against a buyer. If you want a published rate and a payment day, compare with buyers, including Emerging Energy and Green Energy Trading.

Against a mixed model. Some providers create, audit and buy. Ask them to separate the three in their quote, so you can see what each step costs.

Side by side

Audits and why they matter

A provider that audits projects is useful if your claims are being rejected or if you are scaling quickly. Audits do not replace good job files, though. Photos, serials and signed assignment forms are what the regulator and any buyer will ask for; how STC audits work and STC photo requirements show what to keep.

Where Energy Merchants fits

Energy Merchants is a buyer rather than an auditor. It publishes its rate daily on /pricing/ and locks it on lodgement of a complete claim, charges zero fees, and settles established partners within 24 hours (first claim 48-72 hours). A named account manager looks after each partner and the compliance desk pre-checks every claim before lodgement. Settlement is backed by REC Traders. Some installers use an audit specialist and a buyer together; if that is you, ask each how the hand-off works.
