Beauchamp was the son of the Liberal politician and Lloyd's chairman Sir Edward Beauchamp, 1st Baronet, and his second wife Betty Campbell Beauchamp (née Woods). Educated at Eton College, he served in the Life Guards during the First World War. His elder brother, Edward Archibald Beauchamp, was killed in the war and Brograve therefore succeeded to the baronetcy on the death of his father in 1925. Sir Brograve died on 25 August 1976 at the age of 79, when the title became extinct.
At the 1922 general election, Beauchamp stood as a National Liberal candidate for the Lowestoft division of Suffolk. His father had just stepped down as the constituency's MP, and Brograve hoped to win the seat, but he lost heavily. He did not stand again until the 1931 general election, when he was elected as the Conservative Member of Parliament (MP) for Eastern division of Walthamstow. He was re-elected in 1935, and held the seat until he retired from Parliament at the 1945 general election. While in Parliament, he held a number of Parliamentary Private Secretary appointments, including in 1940 to Sir John Reith, Minister for Transport, and in 1942-43 to Richard Law, Parliamentary Under-Secretary of State for Foreign Affairs.
On 8 October 1923, Beauchamp married Lady Evelyn Leonora Almina Herbert, daughter of the 5th Earl of Carnarvon at St Margaret's Church, Westminster. They had one child, Patricia Evelyn Beauchamp (born 11 July 1925, died 7 October 2014). Sir Brograve and Lady Evelyn are buried beside each other in Putney Vale Cemetery in South West London.
In November 1922, before her marriage, Lady Evelyn and her father had been among the first people in modern times to enter the tomb of Tutankhamun in Egypt. In the spring of 1923 Brograve and his parents visited Egypt, and were given a guided tour of Tutankhamun's tomb by the archaeologist Howard Carter.
