Article 18 Approval of an appropriate methodology for carbon saving or cost saving
For the purposes of determining the carbon or cost saving to be attributed to a qualifying action, adjoining installation or excess action, a supplier may apply to the Administrator to approve a methodology other than the Standard Assessment Procedure or the Reduced Data Standard Assessment Procedure (“an appropriate methodology”).
Where the action to which paragraph (1) relates is a qualifying action, adjoining installation or excess action, an application under that paragraph must be made prior to the carrying out of the action.
The Administrator may approve an appropriate methodology if it is satisfied that—
the Reduced Data Standard Assessment Procedure and the Standard Assessment Procedure do not contain a methodology for determining the savings associated with the action for which a determination is required; and
in cases where the methodology is to be used to determine a carbon saving, it makes provision for the likely performance of measures once they are installed in domestic premises.
The Administrator must notify a supplier of its decision under this article.
