Statement of Objections and settlement

24 June 2022: On 23 June 2022, the CMA issued a statement of objections provisionally finding that 10 suppliers of demolition and removal of asbestos services breached competition law by taking part in bid rigging, in the form of cover bidding. The statement is addressed to Brown and Mason Group Limited (as economic successor to the company directly involved in the infringement, Brown and Mason Limited (‘Brown and Mason’)); Cantillon Limited (‘Cantillon’), and its parent company, Cantillon Holdings Limited; Clifford Devlin Limited (‘Clifford Devlin); DSM Demolition Limited (‘DSM’) and its parent companies, DSM SFG Group Holdings Limited Nobel Midco Limited and Nobel Topco Limited; Erith Contractors Limited (‘Erith’) and its parent company Erith Holdings Limited; John F Hunt Limited (‘John F Hunt’) and its parent company John F Hunt Group Limited; Keltbray Limited (‘Keltbray’) and Keltbray Holdings Limited (as economic successor to Keltbray’s parent company Keltbray Group (Holdings) Limited); McGee Group (Holdings) Limited (‘McGee’) and its parent company MFCOIL Limited; T. E. Scudder Limited (‘Scudder’), P.J. Carey Plant Hire (Oval) Limited and Scudder’s parent company, Carey Group Limited; and Squibb Group Limited (‘Squibb’)

Eight of the firms – Brown and Mason; Cantillon; Clifford Devlin; DSM; John F Hunt; Keltbray; McGee and Scudder – have admitted their participation in the alleged bid rigging and agreed to pay fines under the CMA’s settlement policy. Provided they comply with the terms of the settlement, any fines of the settling firms will be discounted to reflect the resource savings to the CMA generated by the firms’ admissions and their cooperation with the CMA’s investigation. The final level of any fines will be decided by a new case decision group, in accordance with the CMA’s administrative process.

Scudder and McGee also reported their involvement in the conduct under the CMA’s leniency policy and will also benefit from a leniency discount on any fines, provided they continue to co-operate and comply with the other conditions of the CMA’s leniency policy.

The CMA’s investigation into 2 further companies, Erith Contractors Limited and Squibb Group Limited continues and no assumption should be made that they have infringed the law.

Press release: CMA provisionally finds illegal cartels in construction industry (24.6.22)

Case information

The investigation concerns suspected infringements of Chapter I of the Competition Act 1998 (CA98).

This case is at an early stage and no assumption should be made that the CA98 has been infringed. The CMA has not reached a view as to whether there is sufficient evidence of an infringement of competition law for it to issue a statement of objections to any of the parties under investigation. Not all cases result in the CMA issuing a statement of objections.

If the CMA issues a statement of objections, it will provide the addressees of that statement of objections with an opportunity to make written and oral representations. Find more information in the CMA’s Procedures in Competition Act cases.

Personal data

The CMA may collect, use and share personal data for its investigations, including investigations under the Competition Act 1998. This includes processing personal data for the purposes of the General Data Protection Regulation and the Data Protection Act 2018.
