Seven of Britain’s largest housebuilders have offered to pay a combined £100 million to affordable-housing programmes in England, Scotland, Wales and Northern Ireland to resolve a Competition and Markets Authority investigation into suspected anticompetitive information-sharing. Barratt Redrow, Bellway, Berkeley Group, Bloor Homes, Persimmon, Taylor Wimpey and Vistry were accused of exchanging commercially sensitive data on house prices, buyer incentives and viewing numbers. The CMA opened the probe in February 2024 amid concerns the practice could distort the cost of new homes. The proposed payment, the biggest the regulator has secured through voluntary commitments, would fund hundreds of subsidised homes for low-income and vulnerable households. The companies have not admitted wrongdoing, and the agreement allows the CMA to close the case without issuing a formal infringement decision. Alongside the financial contribution, the builders have agreed to legally binding undertakings not to share certain sales information in future and to help draft industry-wide guidance on data disclosure. The watchdog will consult on the offer; if accepted, the commitments will take effect and the money must be transferred within three months.
