Responses to statement of scope

Heat Metering and Billing Regulations 2014 notification data

19 December 2017: On 7 December 2017, the CMA issued a mandatory notice under section 174 of the Enterprise Act 2002 to the Department for Business, Enterprise and Industrial Strategy (BEIS) requiring BEIS to produce data relating to heat network notifications to the CMA, to support the CMA’s market study into the heat networks sector. On that basis, BEIS has provided the CMA with a copy of the information provided by heat suppliers (including some personal data, which the CMA will use to contact heat suppliers) as part of the notification process. For more information see BEIS guidance on the heat network metering and billing regulations.

Launch of market study

7 December 2017: The CMA has launched a market study into heat networks. Heat networks involve the generation and distribution of heat to buildings and consist of district heating and communal heating. The CMA will examine whether the sector is working well for consumers.

We are inviting comments on the issues raised in the statement of scope, including from interested parties such as heat network builders, operators and suppliers and their representatives and from consumer groups.
