Groups: Some organisations have registered individually instead of as part of a Group. For more information on how the CRC applies to Groups in the:

Contact details of senior officers: Some organisations have not provided contact details of sufficiently senior officers. The contact details need to be in respect of those with management control of the Primary Member. In the case of companies, this should be a director.

Exclusions: A large number of registrants have misunderstood when they are entitled to claim the exclusion for transport emissions. It is not necessarily the case that all transport emissions are excluded. For more information, see Practice note, CRC Energy Efficiency Scheme: exclusions and exemptions: Exclusion for energy supplies relating to transport.

Mandated Participants: Some Public Bodies have mistakenly thought they classify as Mandated Participants. Mandated Participants have to participate in the CRC regardless of whether they meet the Qualification Criteria (primarily central government departments and Public Bodies in respect of which the Secretary of State or the Welsh Ministers have issued a Local Authority Decision). All other Public Bodies have to assess whether they meet the Qualification Criteria in order to decide if they need to register as a Participant or make an Information Disclosure. For more information, see Practice note, CRC Energy Efficiency Scheme: impact on public sector organisations.

KWh v MWh: Energy data needs to be provided in meggawatt hours (MWh) rather than kilowatt hours (kWh).

AMR: Some organisations have misunderstood how they should calculate the benefit they can receive for the voluntary installation of Automatic Meter Reading (AMR) under the Early Action Metric (EAM). For more information, see EA clarification note.

Changes to registrations: The EA is in the process of producing guidance on how to make changes to an organisation's details once the organisation has completed its registration.

30 September 2010: The deadline for registering as a Participant in the CRC. However, Groups wishing to disaggregate a Significant Group Undertaking (SGU) must do so by 30 June 2010. The EA has asked organisations to contact them if they are unable to meet this deadline. This may be particularly relevant to private equity firms. For more information on disaggregation, see Practice note, CRC Energy Efficiency Scheme: overview: Companies and other types of Undertakings.
