On 24 April, gun salutes from the Tower of London and Hyde Park and bell ringings at Westminster Abbey marked the birth.

On 9 July 2018, Prince Louis was baptised by the Archbishop of Canterbury in the Chapel Royal at St James's Palace, using water from the River Jordan in accordance with tradition. Louis's godparents are Nicholas van Cutsem, Guy Pelly, Harry Aubrey-Fletcher, Lady Laura Meade, Hannah Gillingham Carter, and Lucy Middleton. Louis wore the replica of the royal christening gown, created in 2008 as a copy of the 1841 gown made for Queen Victoria's eldest daughter Victoria, Princess Royal, and used for every royal christening until it was retired for preservation in 2004.
Louis is from birth a prince of the United Kingdom, entitled to the style of Royal Highness under letters patent issued by his great-grandmother Queen Elizabeth II on 31 December 2012, which gave the title and style to all children of the Prince of Wales's eldest son. He is thus styled "His Royal Highness Prince Louis of Cambridge".
Prince Louis is fifth in the line of succession to the British throne, behind his grandfather, father and older siblings, Prince George and Princess Charlotte. Following the implementation of the Perth Agreement, which replaced male-preference primogeniture with absolute primogeniture, he is the first British prince to be ranked behind an elder sister in the line of succession.
