Competition and Markets Authority contacts Hanson UK over potential market data breach

Print this page

UK: The Competition and Markets Authority (CMA) has written to HeidelbergCement subsidiary Hanson UK to express concern and set out actions to prevent a recurrence of a breach of a market data order for “data disclosed which could have been a proxy for Individual Cement Market Data.” The CMA says that on 11 September 2020 Hanson made a payment in error to the Mineral Products Association (MPA) which involved three pieces of information: the payment; relating to MPA subscription fees, remittance advice relating to the payment; and an invoice following the MPA’s querying of the payment. In the view of the CMA each piece of information breached the Cement Market Data Order, because it contained ascertainable cement volume data information.

Hanson has explained that the breach arose due to administrative error.
