UK Housebuilders Under Investigation for Potential Information Sharing

The UK Competition and Markets Authority (CMA) has conducted an investigation into eight major UK housebuilders due to evidence suggesting they shared non-public information, including sales prices and details of incentives for buyers. The housebuilders under investigation are Barratt, Bellway, Bloor Homes, Persimmon, Redrow, Taylor Wimpey, and Vistry [1].

The information exchange, which covered a two-year period, included sales prices, incentives, property status, visitor data, and sales progress at housing developments. This sharing of data between competitors raised concerns about anti-competitive practices in the housing market [1].

As of July 2025, the CMA provisionally accepted commitments from seven of these housebuilders to end this conduct, effectively closing the investigation. The commitments include a legally binding agreement not to share such information for five years, reinforcing compliance with competition law. Additionally, there was a payment made as part of the commitments, notably including an affordable housing payment, though critics argue the financial penalties (approximately £14 million per company on average) were not sufficiently severe given the nature of the misconduct [1][5].

The implications of this investigation are significant. It highlights the regulatory scrutiny on the construction and housing sector for anti-competitive behaviors. The affected companies face reputational damage and financial repercussions [2]. The CMA’s enforcement serves as a deterrent to prevent future exchanges of commercially sensitive information that could distort competition [3].

Taylor Wimpey, one of the investigated firms, also experienced financial impacts from the investigation, posting an £18 million payout linked directly to the probe on information sharing, contributing to its reported half-year loss in 2025 alongside significant other costs related to cladding removal [5].

The Department for Levelling Up, Housing and Communities has stated that it will carefully consider the CMA's final report following its full market study into housebuilding. The report expressed 'fundamental concerns' over the housebuilding market, citing the complex planning system and the limitations of speculative private development as key reasons for not enough homes being built [4].

Bellway, one of the housebuilders under investigation by the CMA, is reviewing the CMA's report. Bellway aims to increase the supply of UK housing and is committed to delivering high-quality new homes that meet local demand and enhance the communities they build in. Bellway has engaged and cooperated fully with the CMA throughout its market study and will continue to do so [1].

The UK government has a long-term plan for housing to build more homes that local communities want and need. The investigation follows a year-long market report by the CMA into the undersupply of new homes in the housebuilding sector. Various local planning departments were found to be under-resourced or lacking clear targets to deliver the number of homes needed in specific areas [1].

The UK government is on track to build one million homes during the current parliament, backed by a £10bn investment in housing supply [6].
