Henry Lawes Luttrell, 2nd Earl of Carhampton (7 August 1743 – 25 April 1821) bought Painshill in 1807 from William Moffat. Luttrell lived at Painshill having fled from the ancestral Luttrellstown Castle near Clonsilla outside Dublin, where his role in crushing the Irish Rebellion in 1798 made it unsafe to stay. (His ancestor Colonel Henry Luttrell had been assassinated in Dublin in 1717 for betraying the Irish to King William III of England.) After his death in 1821, Luttrell's wife Jane lived at Painshill until her death in 1831 when it was sold it to Sir William Cooper, High Sheriff of Surrey.
