This refers to the unique ECO supplier reference number allocated to every supplier by Ofgem. This takes the form AAANNNNNNNNA. The first three characters are an acronym identifier for the company name. The eight alphanumeric characters are the licence-holder's company registration number and the final letter denotes the licence type, E = Electricity, G = Gas. This entry identifies the supplier whose obligations the measure will be credited towards. The ECO supplier reference number that is provided must be for the supplier that owns the measure. In relation to transferred measures, this will be the supplier that is the ‘buyer’. The reference number must be a valid supplier reference. Only entries in the accepted format are valid. CORE Which of the obligations is the measure to be credited towards? This refers to the ECO obligation the measure is to be credited against (i.e. CERO or HHCRO). There are different requirements for each of the ECO obligations.

This indicates the reason for notifying the measure. ‘New Notification’ should be entered when notifying a measure for the first time, provided it is not subject to an extension request. ‘Edited Notification’ should be entered when an existing notification is being amended and the measure is re-notified. ‘Extended Notification’ should be entered when the measure has an extension request associated with it. ‘Re-election’ should be entered when the measure is being re-notified towards a different obligation.

Required Does the measure have an associated primary or secondary measure? In CERO, a supplier can install certain measures only where another measure has been installed. This entry identifies whether the measure being notified has an associated secondary or primary measure. In CERO, a secondary measure must be supported by a primary measure that is installed to a minimum area (and in the case of loft insulation, a minimum depth). Party cavity wall insulation does not need to meet this minimum requirement. This is explained in the ECO2t Guidance. Where a supplier is using more than one primary measure to meet the minimum area condition to support a secondary measure, the supplier should enter the reference number of the primary measure which resulted in the area condition being met or exceeded.
