The Competition and Markets Authority (CMA) has issued letters following the release of their report on the housebuilding market study. The letters are likely to address potential competition concerns identified in the study, aiming to ensure compliance with competition law. The housebuilding industry may face scrutiny and potential enforcement actions if any anti-competitive practices are found. Other companies in the construction sector should also take note of the CMA's actions to assess and mitigate any competition law risks they may face.
