What "verified" means on this page

A company showing the mark has had its identity confirmed against the company register and holds at least one credential we checked with the body that issued it. When a certificate expires the badge comes off automatically, the same day. It is a statement about what was checked and when — not a guarantee about the work. How we verify →
