This site publishes figures that inform an investment decision. So for each kind of data we state where it comes from and when it was verified. If you find something wrong or out of date, tell us: we correct it and date the correction.

We do not publish a local statistic, testimonial or expert quote we cannot substantiate. Auto-generated counters and unverifiable testimonials have been removed from the site.
Grants change yearly and differ by region. They are maintained on our country pages, with their source, rather than copied into articles where they would go stale.
Our simulator computes from the building's real geometry and public data. It does not replace an installer's survey.
Where an official amount is not published or not verifiable, we point to the source rather than state a figure.
