How we are paid
The site does not earn anything yet. We plan to offer a way to request quotes from local installers through a partner, who may pay us a fee for the introduction. This page will name the partner before any quote button appears. You will never pay extra.
How we keep the figures right
The certificate schedule comes from the Clean Energy Regulator. The factor changes on 1 January and 1 July; we check the calculator on those dates and show the date of the last update at the top of the page.
