How to read Thames & Kosmos's ethics scores
Each Thames & Kosmos product on this page carries a 0–100 score built from four checkable inputs: active third-party certifications, disclosed ingredients or materials, published supply-chain information, and the brand's watchdog record. Nothing here is based on Thames & Kosmos's own marketing language.
The spread matters as much as the top score. If Thames & Kosmos's highest and lowest products sit far apart, verification is being applied to some lines and not others — common when a company certifies a flagship range and leaves the rest undocumented. A narrow spread, even at a moderate average, usually signals a consistent policy.
Scores can move without any editorial change, because certification status is re-checked as pages refresh. A lapsed certificate, a new audit or a recall notice will all show up in the product's certification and notes sections.
Questions worth asking before buying Thames & Kosmos
Start with ownership: a parent company's testing or sourcing policy can change what a claim on the packaging actually covers. Then check scope — a certification often applies to one fibre, facility or ingredient rather than the whole product.
Finally, compare within the category rather than against Thames & Kosmos's own range. A mid-scoring product can still be the strongest verified option at its price, and a high-scoring one can be beaten by a cheaper certified alternative.
What each score input covers
| Input | What we check | Why it matters |
|---|---|---|
| Certifications | Active listings in public registers, with scope and expiry | Only externally audited claims can be revoked |
| Ingredients & materials | Full disclosure, hazard flags, recycled or organic content | Comparable without trusting brand narrative |
| Transparency | Named suppliers, factories or audit summaries | Shows whether claims survive scrutiny |
| Record | Recalls, regulator rulings and greenwashing findings | Best short-term signal of quality control |

Frequently asked
Is Thames & Kosmos an ethical brand?+
Thames & Kosmos's standing here is the average of its scored products, built only from verifiable inputs: active certifications, disclosed ingredients or materials, published supply-chain data and its recall or regulator record. Where a claim cannot be checked in a public register, it earns nothing.
Is Thames & Kosmos certified by third parties?+
Any certification we could confirm appears on the individual product cards above. Marks shown are matched to the certifier's own register; self-declared logos and internal awards are not counted.
Why do Thames & Kosmos products have different scores?+
Scores are per product, not per brand. Differences usually come from certification scope, ingredient or material disclosure, and packaging — a certified flagship can sit far above an undocumented line from the same company.
Are there better alternatives to Thames & Kosmos?+
Compare within the category rather than the brand: category rankings list the highest-scoring verified options at each price level, so you can see whether a cheaper certified alternative beats the Thames & Kosmos product you were considering.
