Since the 15th century, the British royal family has granted businesses and tradespeople a royal warrant of appointment, and it goes to products and services that supply the monarchy on an ongoing basis for at least five years. Essentially, it’s an endorsement of quality, and products granted a royal warrant can display the grantor’s coat of arms on packaging and websites while advertising their status as suppliers.

Royal warrants are also void upon the death of the grantor.

With Queen Elizabeth II’s death earlier this month, over 600 active appointments became void, including tradespeople like piano restorer The Period Piano Company and large multinational CPG brands like Heinz. Now, all of the companies must reapply for a new royal warrant within two years or adjust their packaging.
