Read the latest magazine Industry News Lead Two UK Roofing Firms Admit to Lead Cartel – Third Responds 12 June 2020 TWO OF THE UK’s largest suppliers of rolled lead have admitted to taking part in anti-competitive arrangements and could face fines of more than £11 million. The admission from two of the biggest players in the market: Associated Lead Mills Ltd and H.J Enthoven Ltd (trading as BLM British Lead), follows a Competition and Markets Authority (CMA) investigation. A third company, Calder Industrial Materials Ltd, is under continuing investigation in relation to one of the arrangements and has not made any admissions. In its original provisional findings, the CMA alleged that Associated Lead Mills, BLM British Lead and Calder Industrial Materials – which together account for about 90% of UK rolled lead supplies – entered into a cartel to share the market amongst themselves through, for example, the allocation of customers. The CMA has now the three firms with a ‘supplementary statement of objections’, which outlines its updated allegations. Four illegal arrangements The CMA’s revised provisional view is that there was not a single overall cartel arrangement, but rather four individual arrangements that broke competition law. The CMA’s revised provisional findings indicate that Associated Lead Mills and BLM British Lead entered into arrangements including: sharing the market, including by arranging not to target certain customers colluding on prices exchanging commercially sensitive information on prices arranging not to supply a new business that risked disrupting the firms’ existing customer relationships and was also a potential competitor in the market Admitting cartel guilt Both Associated Lead Mills and BLM British Lead have now admitted to their parts in the cartel arrangements, which took place between October 2015 and March 2017. Associated Lead Mills will pay a fine of £1,815,614 and BLM British Lead will pay a fine of £9,516,572 as part of a settlement agreement with the CMA. Martin Armour Calder Industrial Materials For Calder Industrial Materials, the CMA has provisionally found that it became involved, at a later stage, in the arrangement with Associated Lead Mills and BLM British Lead not to supply a new business that risked disrupting the firms’ customer relationships and was a potential competitor in the market. Calder Industrial Materials has made no admission of liability and the CMA’s investigation is continuing. Martin Armour, director of Calder Industrial Materials Ltd has issued a statement in response to today’s CMA findings. Calder Industrial Materials Ltd Statement 12 June 2020 Today the Competition and Markets Authority (CMA) issued a press release in relation to its ongoing investigation into suspected anti-competitive arrangements in the UK roofing materials sector. The press release confirms that the CMA has reached a settlement with the parent companies of Associated Lead Mills (ALM) and British Lead Mills (BLM) who have admitted to allegations that they entered into anti-competitive agreements involving: sharing the market, including by arranging not to target certain customers; colluding on prices; exchanging commercially sensitive information on prices; and arranging not to supply a new business that risked disrupting the firms’ existing customer relationships and was also a potential competitor in the market. The CMA has found that Calder did not participate in the anti-competitive agreements between ALM and BLM relating to market sharing, collusion on prices or the exchange of commercially sensitive information. The case against Calder is now limited to a single allegation that it agreed with ALM and BLM not to supply another company operating as an agent. Calder continues to strongly deny this allegation and will be responding to the CMA’s supplementary statement of objections, which was also issued today, in due course. The National Federation of Roofing Contractors Comment The National Federation of Roofing Contractors, representing 1approximately 1,200 roofing contractor members in the UK industry has issued a statement: “NFRC prides itself on high standards and professionalism and therefore takes allegations of breaches of competition law extremely seriously. Anti-competitive behaviour will not be tolerated. We are aware that Associated Lead Mills and BLM British Lead have admitted to their parts in anti-competitive arrangements. We do not wish to comment on an ongoing investigation, but will do so when the CMA has made their final judgement later this year.” Parent and related cartel companies The CMA provisionally considers that those businesses directly involved in the alleged infringements or are liable as parent companies of the undertakings directly involved are: Associated Lead Mills Limited, Royston Sheet Lead Limited (previously Jamestown Metals Limited) and their parent company International Metal Industries Limited (previously International Industrial Metals Limited) H.J. Enthoven Limited (trading as BLM British Lead) and its parent company Eco-Bat Technologies Limited Calder Industrial Materials Limited and its parent company Calder Group Holdings Limited.
