Editorial policy
How Wattlyze separates calculated results from editorial claims and keeps official data behind every estimate.
Purpose of each page
Each page exists to help a household understand one concrete energy cost decision, not to fill a keyword.
Sourcing standard
Nothing is presented as an official figure unless a published dataset supports it. Every data-backed result shows its source and data date, and each language version is written for that language.
Corrections
Dataset revisions that change an estimate are recorded in the data update log. Formulas and assumptions are explained on this methodology page. Source dates change when the source updates.
