No UK trading entity found
We searched UK Companies House thoroughly (exact name, exact phrase, and plausible variants) and found no matching registration, despite this site presenting as UK-based. This caps the CoA tier below green regardless of score. It is not proof of wrongdoing, only that we could not confirm who operates this business: see methodology.
- ⚠ Publishes benefit claims next to products despite research-only framing
- ⚠ No UK trading entity could be found despite a thorough search, though the site presents as UK-based
