Royal Warrant It is a mark of acknowledgement of those who have supplied goods or services to the Households of HM The Queen or HRH The Prince of Wales for at least five years and who have an ongoing trading arrangement. Her Majesty The Queen visited Hillbrush in 1952 during a trip to the local area. In 1981 Hillbrush was granted a Royal Warrant to Her Majesty The Queen. This year, we proudly celebrate 40 years of supplying brushes to the Royal Households as well as our Chairman, Philip Coward, appointed Hon. Treasurer, Council Member and Trustee of The Royal Warrant Holders Association.
