Read the latest magazine Industry News Lead CMA Update Suspected Rolled Lead Cartel Investigation 27 June 2019 THE Competition Markets Authority (CMA) has today (27 June 2019) announced that it will extend the time allowed for responses to its investigation into three rolled lead companies that are suspected of forming a cartel. The extension, that is ongoing up until October, will allow Associated Lead Mills Ltd, J. Enthoven Ltd and Calder Industrial Materials Ltd more time to provide written or oral representations in response to the investigation’s findings (‘statement of objections’) set out by the CMA. The results of the case may, however, be published before this time. Lead Cartel Investigation The CMA’s investigation into roofing materials began in July 2017. Since then, it has provisionally found that the UK’s three principal suppliers of rolled lead have broken competition law. All three companies are suspected of fixing lead prices, sharing out customers between themselves, exchanging commercially sensitive information and restricting the supply of rolled lead to any other company wanting to enter the market. Together, the suspected cartel accounts for about 90% of the rolled lead market. Rolled lead is an important, high-value product for the construction industry, used for waterproofing roofs, including churches and historic buildings, as well as flashing on domestic properties. If found guilty, the companies involved can face fines of up to 10% of their turnovers: In 2017 Associated Lead Mills Ltd declared a turnover of £62,370,006. In 2017 J. Enthoven Ltd declared a turnover of £157,717. In 2017 Calder Industrial Materials Ltd declared a turnover of £41,801. >> Read more about the lead cartel in the news Previous article Earthquake-Ready Venues for 2020 Tokyo Olympics and ParalympicsNext article Guttercrest Group Welcomes New Director of Operations Share article You may also like View all News Industry News +2 20 March 2026 RA Issues Revised Safety Guidance on Rooflight Covers Awards and Events +3 20 March 2026 The Great British Slate Off Returns for 2026 Green Roofs +3 20 March 2026 Swansea Joins Global Network of Biophilic Cities Featured Solutions +3 19 March 2026 Flush Fitting Rooflights by Clement Sign Up to Roofing Today Stay up to date with all of the latest news from Roofing Today by signing up to our weekly Bulletins… Sign Up Today Get in Touch Check out the latest issue 123 March-April 2026 View Now Past Issues Get in Touch
