(b)is a district heating connection;
(c)is not the replacement of an efficient heating system with another efficient heating system of the same kind; and

(b)in any other case, before the relevant connection is installed.
(5) The Administrator may approve an alternative methodology if—
(a)it is satisfied that—
(i)neither the Standard Assessment Procedure nor the Reduced Data Standard Assessment Procedure contain an appropriate methodology for determining the annual cost savings achieved by the relevant connection; and
(ii)the alternative methodology is an appropriate methodology for determining the annual cost savings achieved by the relevant connection; or
(b)the alternative methodology is published by, or on behalf of, the Secretary of State as a replacement for the Standard Assessment Procedure or the Reduced Data Standard Assessment Procedure.
