Trading as SEALSTOP LIMITED, registered at Companies House number 14904754.

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. Number published by the company at https://sealstop.co.uk. Source, checked 2026-08-29.
• uk hq: Registered office is a UK address: Catalyst, York, YO10 5GA. 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.
