In 1802, Horrocks entered parliament as Tory member for Preston. Stanley then tried to undermine his economic base, by investing in Preston rivals Watson, Myers Co. After his death less than two years later, his brother Samuel Horrocks took over his seat in an uncontested by-election, Sir Thomas Dalrymple Hesketh, 3rd Baronet having held back. Death and legacy Horrocks died in London of brain fever, reportedly resulting from over-work. During his 13 years in Preston he had amassed a personal fortune of at least £150,000, and set the foundations for the Horrocks-Miller mill owning dynasty that dominated Preston into the mid-nineteenth century. In 1801 Horrocks built "The Lodge" (later called Penwortham Hall) in Penwortham as a residence for himself. The property, which is a Grade II listed building, is today used as a series of private dwellings. He died in 1804 and was buried at St Mary's Church, Penwortham.
