Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

• UK company

  Registered at Companies House as BLUNDELL HARLING LIMITED, number 00449650. Checked 2026-08-29.

  Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.

• UK operations

  The company describes its own premises: "Blundell Harling Ltd manufactures a wide range of promotional products in our factory on the Jurassic Coast in Dorset. Blundell Harling also manufactures navigational products for the leisure and commercial marine indust" Self-declared (§3.3), read from the company's site. Source.

  Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.

• British-owned

  No majority shareholding traced outside the UK. Companies House.

  Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.

• Where it is made

  The maker doesn't say, so neither do we.

  This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
