AWhole market, 20 of 24 points
Same engine as elpriser.dk, but less well executed: no company name on the front page, outdated subpages, and a “cheapest” headline whose assumptions you have to find in the method.
54 of 54 retailers shown with a price
Who can be listed
All companies, same engine as elpriser.dk
Who is behind it
Mondo Media ApS
Portaltjek is published by the electricity retailer Osmund, which pays no comparison site and benefits when sites show the whole market. The analysis was carried out with AI, following a public method.
What you should know
The front page footer lacks a company name and CVR.
The headline’s “cheapest” is apparently contradicted by the list; the explanation (discounts and remarks are excluded) is in the method, not next to the headline.
Old subpages with stale prices and only partner boxes are still online.
Who is behind it?
Mondo Media ApS (Elpriser.dk ApS), CVR 43489984: the front page footer names no company; older subpages have “Mondo Media ApS”.
People: Mathias Clausen
Sister sites: elpriser.dk, elselskab.dk, elselskaber.dk, elselskabdanmark.dk, elleverandoer.dk
How does the site make money?
Commission per switch from 10 partners; 4 highlighted “commercial partnerships”.
Does a retailer have to pay to be listed?
No: the front page runs the elpriser.dk engine (“184 electricity agreements from 54 electricity companies” according to the site; same feed as elpriser.dk, only about the first 25 rows seen). An older static subpage shows only 34 names and 7 partner boxes.
The site shows Osmund. This earns no points.
What does the site say itself?
“184 elaftaler fra 54 elselskaber” (“184 electricity agreements from 54 electricity companies”)
What we saw
Ranking: As on elpriser.dk (same feed and rule). The headline names Altid Energi (DKK 7,816/year) as cheapest, even though AURA (7,800, including a first-year discount) and Dansk Strøm (7,787, “Advised against”) are cheaper in the list: both are excluded by the site’s own rule, but that requires reading the method.
Price basis: Full price via the elpris.dk feed (nightly).
Updates: Date shown; legacy page “Last updated 8 Aug 2026”.
Method on the site: “How we make money” exists.
Error reporting: Yes.
Confidence: medium. Checked 29 Oct 2026.
