The UIA had another meeting with DESNZ to once again make the case that TPIs should be directly regulated rather than subject to indirect regulation via suppliers. The rejection of a QDSS that has met the criteria set out by Ofgem, based  purely on the supplier’s [vendor] preference, clearly illustrates why the current model is not fit for purpose. When asked about the timing of a decision following their September 2024 consultation on regulating TPIs, DESNZ did not provide a firm commitment. They advised that progress depends on related workstreams, particularly the ongoing review of Ofgem’s role. The only indication given was that consultation responses will be published “soon.”
