The Whitbread was founded in 1971: authors must have been resident in the United Kingdom or Ireland for over six months of each of the previous three years (although UK or Irish nationality is not essential). Books must have been first published in the UK or Ireland between 1 November of the previous year and 31 October of the current year. Books previously published elsewhere are not eligible.
It has five categories - First Novel, Novel, Biography, Poetry and Children's Book. For each category there are three judges - generally an author, a bookseller and a journalist. They select a shortlist of four books, which includes the winner. Their criteria is to select well-written, enjoyable books that they would strongly recommend anyone to read. Books must be submitted directly by publishers, not by authors.
After 2006, Costa Coffee, a subsidiary of Whitbread, took over sponsorship of the award, which was renamed the Costa Book Awards.
In 2022, Costa announced that the award would cease after 51 years: the 50th, and final, award was announced in 2021. No reason was initially given for the cessation.
