Following an investigation which started in 2019, the Competition and Markets Authority (CMA) has provisionally concluded that the firms colluded on prices through illegal cartel agreements when submitting bids in competitive tenders for contracts. These bids were rigged with the deliberate intention of deceiving the customer that they were competitive when that was not the case. Cover Bidding The bids were rigged by one or more construction firms which agreed to submit bids that were deliberately priced to lose the tender. This practice, known as ‘cover bidding’, can result in customers paying higher prices or receiving lower quality services. The CMA is proposing to impose fines on the businesses concerned if it reaches a final decision confirming that they have broken the law. £.5m Compensation In addition, the CMA has provisionally found that seven of the firms, on at least one occasion each, were involved in arrangements by which the designated ‘losers’ of the contracts were set to be compensated by the winner. The value of this compensation varied but was higher than £500,000 in one instance. Some firms produced false invoices in an attempt to hide this part of the illegal behaviour. The CMA has provisionally found that the collusion affected 19 contracts for demolition work in London and the Midlands, including contracts for the development of Bow Street’s Magistrates Court and Police station, the Metropolitan Police training centre, Selfridges, Oxford University, shopping centres in Reading and Taplow, and offices on the Southbank, London. Not all of the firms were involved in colluding in each of these contracts, and not every contractor who submitted a bid for these contracts was involved in the illegal collusion. Admitted Guilt Eight of the firms have admitted their involvement in at least one instance of bid rigging between January 2013 and June 2018: Brown and Mason, Cantillon, Clifford Devlin, DSM, J F Hunt, Keltbray, McGee, and Scudder. Two other firms, Erith and Squibb, have not admitted their involvement in any bid rigging and it should not be assumed that they have broken the law. Michael Grenfell, the CMA’s Executive Director for Enforcement, said: “The construction sector is hugely important to Britain’s economic well-being. Bid rigging can result in worse deals, which can leave businesses – and sometimes taxpayers – out of pocket. “This is unacceptable, and the CMA won’t hesitate to come down hard on these activities and impose appropriate fines.” The CMA’s findings are provisional, and the organisation says it should not be assumed that any company has broken the law at this stage. The final total of any fines to be paid will be disclosed at the end of the investigation. The CMA’s “Cheating or Competing” campaign has advice for businesses to help them spot, report and deter illegal anti-competitive practices such as market sharing, fixing prices and bid-rigging. >> Read more about construction cartels in the news Previous article Anglesey Roofing Firm Secures Another Iconic ProjectNext article Winners of the MAC Awards 2022 Announced 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
