Britishpost Reviews 1

Using "British" in a company name is illegal without government permission. I really doubt that has been obtained by this firm.
"The Secretary of State would need to show that the company is pre-eminent in its field by providing supporting evidence from an independent source such as a Government department or a trade association. If the word 'British' is qualified by words that do not describe an activity or product, for example by using a 'made-up' word, then evidence of pre-eminence is not necessarily essential. But you would be expected to show that your company is substantial in relation to its activity or product and that it is eminent in its own field."
