Case information
On 10 December 2024, the CMA launched an investigation under Chapter I of the Competition Act 1998 (CA98) into suspected anti-competitive conduct in the form of bid-rigging in connection with the supply of roofing and other construction services to schools eligible to apply for funding from the Department for Education’s Condition Improvement Fund (CIF).
In January 2026, the CMA updated the scope of its investigation and expanded it to include additional parties. The CMA is investigating suspected anti-competitive conduct in the form of bid-rigging in connection with the supply of roofing and other construction services to schools, including those eligible to apply for funding from the Department for Education’s Condition Improvement Fund (CIF), and to other public and private sector bodies.
No assumption should be made at this stage 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 addressee(s) of that statement of objections with an opportunity to make written and oral representations, before it makes a final decision. Find out more about our investigation procedures in CA98 cases.
