Born and educated in Hannover, he arrived in England in 1728. As he was young and unmarried, he was not given his own establishment. Quietly, the opposition to the king made overtures to Frederick, as in
their opinion the future lay with him. In 1734 he began demanding a wife and an establishment for himself; but for a wife he had to wait until 1736, and another two years before he would rent Leicester
House.
When he married he had expected to have his allowance doubled, as had happened when his father had married. However, George II refused this as the money would come out of the Civil List which would reduce his own income. When requests were made through Parliament, George II and his wife were furious as this forced the Parliamentarians to choose between father and son. Thanks to Sir Robert Walpole, the motion was defeated.
While his wife was in labour they fled to St.James's, which inflamed the already existing disharmony between him and his parents. Only now did he rent Leicester House which became the centre for the
opposition. It was his support for the opposition which caused the downfall of Walpole and also the rise of Chatham.
In general he spent his time irritating his father, the king, and also his ministers. Consequently, his parents loathed and detested him, even to the point of when his mother was dying she refused to let
him come to see her, regarding his request as hypocrisy. Frederick was described as an undutiful son, unfaithful to his mistresses, and disloyal to his friends; but then Lord Hervey was prejudiced. After
having been friends, they had quarrelled over politics and a woman and ended up enemies. 
Frederick was the first Hannoverian to show a genuine interest in art; amongst paintings he collected, two van Dycks and a pair of Rubens landscapes are still in the royal collection. He involved himself with landscape gardening at Kew, which his widow and son later developed into the Royal Botanic Gardens. He loved music and played the violincello.
He was an affectionate husband and father and rumours about mistresses were exaggerated. In fourteen years of marriage he became the father of nine children. He was always concerned about his children and involved himself with their education. On 6 March 1751, Frederick told Doddington that he had caught a cold. On 15 March he was regarded as improving and, on the 20th, Doddington was told he was much better. However, he died that evening, aged 44.
