Write My Letter Now →Members of the public have always had the right to write to the Monarch. Letters are received by the Royal Household at Buckingham Palace, and correspondence sent in good faith, whether offering congratulations, raising a matter of national concern, sharing a personal story, or simply expressing loyalty, is acknowledged by the Royal Correspondence team.

Your letter is then printed and posted by Royal Mail to Buckingham Palace.
