The Competition and Markets Authority (CMA) consulted on draft versions of the measures in February.

The final measures are now contained in 2 documents: the Cement Market Data Order (PDF, 369KB, 21 pages) and the final undertakings (PDF, 288KB, 11 pages) . The order will restrict the disclosure and publication of production and sales volume data by cement producers in Great Britain (GB). In addition, the CMA has accepted final undertakings offered by the Mineral Products Association (MPA) concerning the use of an independent third party for the collection and disclosure of production and sales volume data which it receives from GB cement producers. The final undertakings come into force on 13 April and the order comes into force on 14 April 2016.

The order and undertakings are the final measures resulting from the Competition Commission’s (CC) investigation into the supply or acquisition of aggregates, cement and ready-mix concrete in GB. The CC had found that there were both structural and conduct features of the GB cement markets which combined to give rise to an adverse effect on competition through co-ordination by the largest GB cement producers in these markets. The CC imposed remedial action which required Lafarge Tarmac to sell one of its cement plants and Hanson to sell one of its ground granulated blast furnace slag (GGBS) plants to improve competition in the cement and GGBS markets. Both of these sales have been completed.

The CC also said that it would implement 2 further remedy measures aimed at reducing transparency in the GB cement markets, comprising: (a) a prohibition on suppliers of cement and cementitious products from sending their customers generic price announcement letters, which was implemented in January 2016; and (b) restrictions on the disclosure and publication of GB cement production and sales volume data.

The order, undertakings and all other information relating to the investigation can be found on the investigation’s case page.
