Seazenal
Trading as SEAZENAL LTD, registered at Companies House number 16085325.
What we have checked
Every brand here has to clear one test before it is listed at all: the company is a UK legal entity with real activity here. That is a question about the business, and it is deliberately not the same question as where any individual product is made.
- uk registered entity: Companies House record resolves, status active. This maker publishes no company number and no registered postcode. The domain https://seazenal.com is the registered company name, and the full registered name, suffix included, appears on the page. Inferred by us (§3.3), not stated by the company. Source, checked 2026-08-29.
- uk hq: Registered office is a UK address: Office 12128 182-184 High Street North, London, E6 2JA. This is the registered office, which is not necessarily where the company operates. Source, checked 2026-08-29.
We have only checked company registration so far. Evidence of UK employment or a UK site is the next thing we intend to gather, and until we have it we say so on every product rather than implying it.
