The order uses evidence TrustList held on 5 October 2026: client reviews, vetting, awards and facts each company states on its own website, which we read and dated. Nobody pays to be placed. Companies with nothing checkable are listed, not ranked, and positions are fixed until the January 2027 edition. A company can move up by adding client reviews or verified facts to its free profile.
