GBS has been based in Grantham since May 1975, when known as Chatto, Bodley Head & Cape Services. Chatto & Windus had merged with Jonathan Cape in 1969. The former site was officially opened on 23 September 1975 by Michael Foot MP. Random House was formed in 1987 from a combination of book companies, and in 1990 the site became known as Grantham Book Services. The company won an award in 1992 from the British Book Awards. Next door to GBS and a Gala Bingo is Cathodic Protection, who with BGB Innovation both won in 2009.
