How this site is funded

What WattDraw earns, what it does not, and why a commercial relationship cannot move a published figure.

Every commercial relationship, listed

,

This table is generated from data/affiliates.json, the same file every disclosure on the site reads. There is no second copy of this information written into prose somewhere, which is the only way a statement like the one above stays true.

,
Outbound links to these merchants run through /go/, which states the position again before you leave.

Advertising

,

This site currently displays no advertising. The page templates reserve space for it, so that turning it on later cannot shift the layout — but nothing is being served into that space today.

,

What this cannot affect

,

Every running-cost figure here is computed from public data by a documented method. The method page gives the formula and the calibration; sources gives the datasets and their checksums. A commercial relationship cannot move those numbers without the arithmetic visibly breaking, and that is the reason the method is published rather than summarised.

,

Where the honest advice is to spend nothing, this site says so. The measurement guide tells you to read your own meter before buying anything, and the second-refrigerator advice is to retire the appliance rather than replace it — in both cases the recommendation that earns least is the one on the page.

Marking

,

If a link ever becomes paid, it carries rel=”sponsored”, the page shows the notice above the first such link rather than in a footer, and the /go/ interstitial says so again before you leave. All three come from the same file, so they cannot disagree.
