Peter Brotherhood Limited is an engineering company based in Peterborough, which was established as a private company on the 16th December 1907. Its history starts in 1867 when Peter Brotherhood and G. D. Kittoe formed Kittoe and Brotherhood at 63 and 56 Compton Street, London, this partnership dissolved in 1871. Brotherhood later joined Mr Hardingham and became Brotherhood and Hardingham.
