Our charter

Our mission and how we work

Our mission is to make energy topics understandable for households and businesses. Every guide is written from original reporting, built on practical questions, and checked before publication.

We do not accept sponsored rankings, and no content is shaped by financial grant brokers or renovation contractors. Where a subject depends on current aid, prices, or rules, we state the conditions and the date they apply.

Verification standards

How we check what we publish

Public tariffs, building codes, and legal notices are cited from official French sources. We record the document, the issuing body, and the date of the version we consulted.

When a rule changes, we update the guide or add a dated correction note rather than leaving outdated conditions in place.

We do not invent figures, testimonials, partnerships, or guaranteed results. Legal notices and our privacy policy are available in the site footer for every reader.

Corrections and questions about sourcing can be sent to our editorial desk through the contact page.
