Forterra plc is a leading UK manufacturer of essential clay and concrete building products, serving the construction industry through its three core segments: Bricks, Blocks, and Bespoke Products. As the UK's second-largest brick producer, it operates nine brick plants with an annual capacity of 690 million bricks, alongside production of energy-efficient concrete blocks like the Thermalite range and high-margin Fletton bricks historically used in a quarter of England's post-WW2 housing stock. The Blocks segment supplies dense and lightweight blocks plus permeable paving, while Bespoke Products offers customized precast concrete under the Bison Precast brand, chimney solutions, roofing, and innovative offsite walling systems using Design for Manufacture and Assembly approaches. With 15 manufacturing sites and approximately 1,600 employees, Forterra plc supports volume housebuilders, commercial projects, and infrastructure like HS2. Originally Hanson Building Products, it rebranded in 2016 following its London Stock Exchange listing, emphasizing efficiency, sustainability through durable thermal mass products, and market positions in a consolidated industry dominated by few key players.
