IN Brief:
- The Competition and Markets Authority has named 12 businesses in an ongoing roofing and construction services investigation.
- The probe includes suspected bid-rigging linked to schools and other public and private clients.
- The case reinforces the compliance pressure surrounding construction procurement, tendering, and framework work.
The Competition and Markets Authority has named 12 businesses under investigation as part of an ongoing probe into suspected bid-rigging in roofing and construction services.
The investigation was launched in December 2024 and initially focused on work linked to the school Condition Improvement Fund. It has since broadened to cover schools more generally, as well as other public and private clients. The CMA has stressed that no finding has been made that competition law has been breached.
The companies named by the regulator are:
- AMR Consult Ltd
- Blue Cube Contracting Ltd
- Central Roofing and Building Services Ltd
- Higham Flat Roofing Ltd (trading as Higham Roofing and Construction)
- ICE Roofing & Cladding Ltd
- Inspire Contract Services Ltd
- M&J Group (Construction & Roofing) Ltd
- Parias Construction and Interiors Ltd
- PSARLD Ltd (trading as Peter Smith Associates)
- RAM Building Consultancy Ltd
- Russell Trew Ltd
- Stoic Roofing and Construction Ltd.
The investigation concerns suspected bid-rigging, a form of cartel behaviour in which competing businesses coordinate tender responses instead of competing independently. In construction, such conduct can involve cover pricing, market sharing, rotation of winning bids, or coordination over which business pursues particular work. Where proven, it can distort procurement outcomes, increase costs, and damage confidence in tendering systems.
School work is a particularly sensitive area because clients are often public bodies working within fixed capital budgets. Roofing packages may appear narrower than major building contracts, but they sit within a procurement environment where value, transparency, safety, and accountability are central. Even small movements in tendered costs can affect how many projects proceed, how quickly defects are addressed, and how much funding remains for other maintenance needs.
The probe comes during a period of heightened legal and commercial scrutiny across the construction sector. A separate proposed class action against major housebuilders has already placed competition practices under renewed attention, with allegations focused on commercially sensitive information sharing in the new-build housing market. Taken together, the cases show how competition risk can extend from obvious cartel behaviour into the handling of pricing, sales, incentives, and market information.
Construction procurement has always relied on a difficult balance. Clients need competitive tension, enough bidders to create price confidence, and sufficient market capacity to deliver the work. Contractors face rising labour costs, insurance pressure, volatile materials pricing, cash-flow exposure, and tight margins. Where controls are weak, those pressures can make procurement behaviour more vulnerable, particularly in specialist trades with a limited number of regional suppliers.
Bid-rigging investigations also affect organisations beyond the companies directly named. Main contractors, local authorities, academy trusts, consultants, and framework operators are likely to review how tender lists are built, how bids are evaluated, how conflicts are managed, and how unusual pricing patterns are identified. Repeated bidder behaviour, unexplained withdrawals, suspiciously high losing bids, or consistent allocation of work between the same companies are all warning signs that procurement teams may be expected to monitor more closely.
For specialist contractors, competition compliance cannot be treated as a boardroom issue detached from estimating teams and regional managers. Tender discussions, subcontractor relationships, informal market intelligence, and supplier conversations can all create risk if commercially sensitive information is exchanged or competitors coordinate behaviour. Training, document control, escalation routes, and audit trails are now basic commercial safeguards.
The roofing market also operates under intense programme pressure. School buildings often require work during holiday windows, creating tight delivery periods and limited flexibility. Legacy estates, urgent repairs, asbestos risks, weather exposure, and safeguarding requirements make delivery complex. Those conditions increase the need for transparent procurement, reliable pricing, and clear separation between competing bidders.
The CMA investigation remains ongoing, and the named companies have not been found to have breached competition law. Even so, the announcement places construction tendering behaviour under sharper scrutiny at a time when public clients are under pressure to prove value for money and specialist contractors are competing for framework and repeat work. Independent bids, robust records, and disciplined commercial conduct are likely to receive closer attention across the sector.
