Overview
Clays is a British printing company best known for producing books for publishers in the United Kingdom and international publishing markets. Its principal operating base is in Bungay, Suffolk, where the business developed from a nineteenth-century printing lineage associated with Richard Clay and his descendants. The company’s activities have evolved from general commercial printing into specialist book production, with particular emphasis on the manufacture of hardback and paperback titles at industrial scale. The company’s origins are connected with Richard Clay, who first managed and later acquired the London printing business Burton & Briggs. In 1827, Clay became its owner. After his retirement in 1868, his sons established the partnership R. Clay, Sons & Taylor. That business expanded beyond London through the acquisition of Childs & Son, a Bungay printer, in 1876. The Suffolk operation subsequently became the core of the company’s long-term identity. Although it began as a general printer, the business increasingly concentrated on books after the First World War, reflecting the growth of mass-market publishing and the professionalisation of commercial book manufacture. Clays became a publicly traded company on the London Stock Exchange in 1956 and joined the St Ives Group in 1985. Its corporate ownership changed again in 2018, when Italian printing group Elcograf acquired the company from St Ives for £23.8 million. Clays has since continued operating as a specialist book printer rather than as a consumer-facing publisher. Its role is generally behind the scenes: it manufactures titles commissioned by publishers, distributors, authors, and other rights holders rather than selling books directly under its own editorial imprint. The company has printed a wide range of commercially prominent and culturally significant works. Reported examples include the Harry Potter books, titles by Tom Clancy and Terry Pratchett, books associated with Margaret Thatcher, Tony Blair, Stephen Fry, and Philip Pullman, Penguin Clothbound Classics, David Jason’s autobiography My Life, Helen Fielding’s Mad About the Boy, Michael Wolff’s Fire and Fury: Inside the Trump White House, and Andy Shepherd’s The Boy Who Grew Dragons series. It has also manufactured technically distinctive editions, including a scratch-and-sniff version of Roald Dahl’s The Twits. Security and production accuracy are important parts of the company’s role because printers may handle unreleased manuscripts and time-sensitive editions. In 2003, an employee stole chapters from Harry Potter and the Order of the Phoenix and attempted to offer them to The Sun. Separately, in 2013, pages for David Jason’s autobiography and Helen Fielding’s Mad About the Boy were accidentally mixed up during production, illustrating the operational risks involved in large-scale book manufacturing. Clays remains an active industrial employer and book-production business. It reported printing approximately 167 million books in 2024. Its Bungay facility was featured in the BBC documentary series Inside the Factory in an episode about hardback books broadcast in January 2025. In February 2025, Clays announced the acquisition of TJ Books, a Padstow-based printer that had entered administration earlier that month. The transaction expanded Clays’ production footprint and preserved a connection with a specialist regional printing operation. The company employed 790 people in 2021, according to the available reference material.
History
Clays traces its history to the nineteenth-century printing activities of Richard Clay. Clay first managed Burton & Briggs, a London printing business, and became its owner in 1827. He remained connected with the business until retiring in 1868. His sons subsequently created the partnership R. Clay, Sons & Taylor, which continued the family’s involvement in printing and expanded its activities. A major step in the company’s development came in 1876, when R. Clay, Sons & Taylor acquired Childs & Son, a printer in Bungay, Suffolk. The Bungay operation became the foundation of the company’s enduring presence in the town. The business initially worked as a general printer, but after the First World War it moved toward greater specialisation in book printing. This shift placed the company within the expanding industrial infrastructure of modern publishing, where printers increasingly supplied publishers with consistent, high-volume production rather than serving only local commercial needs. Clays floated on the London Stock Exchange in 1956. Its public-company period formed part of a broader consolidation of British printing, as established regional printers developed larger production capabilities and became connected with wider corporate groups. In 1985, Clays joined the St Ives Group. The association gave the business a place within a diversified printing group while it continued its focus on book production. Ownership changed in 2018 when Elcograf, an Italian printing company, acquired Clays from St Ives for £23.8 million. The acquisition transferred Clays into an international printing context while preserving its specialist role and Bungay operating base. Clays has continued to manufacture books for publishers and other customers rather than operating primarily as a publishing imprint or consumer retail brand. The company’s production history includes many prominent titles and authors. Its reported work includes the Harry Potter books, books by Tom Clancy, Terry Pratchett, Margaret Thatcher, Tony Blair, Stephen Fry, and Philip Pullman, as well as Penguin Clothbound Classics. It has also produced children’s series, memoirs, political nonfiction, commercial fiction, and special-format editions. Examples include Andy Shepherd’s The Boy Who Grew Dragons, Michael Wolff’s Fire and Fury: Inside the Trump White House, David Jason’s My Life, Helen Fielding’s Mad About the Boy, and a scratch-and-sniff edition of Roald Dahl’s The Twits. The company has also experienced incidents demonstrating the sensitivity of book printing. In 2003, an employee stole chapters from the forthcoming Harry Potter and the Order of the Phoenix and tried to sell them to The Sun. In 2013, pages from two separate books were accidentally mixed up during production. These events differ in nature but both show how printers sit at a critical point between publishers and the public, handling confidential content while managing complex physical production processes. In 2021, Clays employed 790 people. It printed approximately 167 million books in 2024, indicating that the business remains a significant industrial producer despite the broader digitisation of reading and publishing. Its Bungay works were presented to a general audience in the BBC’s Inside the Factory episode Hardback Books, broadcast in January 2025. The same year, Clays announced the acquisition of TJ Books in Padstow after that company entered administration. The acquisition broadened Clays’ operations and represented a further step in the consolidation of specialist book-printing capacity in the United Kingdom.
