Last month, (May 2019) the way that Ofgem review decisions changed.
In a letter published by ofgem at the end of April, they confirm that after a consultation they will be implementing changes.
“Our decision We will implement the proposed changes to the decision review process, for both Great Britain and Northern Ireland NDRHI schemes. This means that we will be removing the formal review stage, allowing applicants / participants to request a review of any decision made by us under statutory provisions in place, in line with the NDRHI GB Regulations (Regulation 86) and the NDRHI NI Regulations (Regulation 50). This will aim to improve the review and decision making process, enabling us to make a final, robust decision in a much shorter timescale.“
