BSCP27 sets out the process for TAA inspections of both CVA and SVA HH Metering Systems. Please note that during the REC Transition period, Elexon agreed with the REC and The Authority that, for the purposes for this BSCP only, the SVA MOA governance will remain under the BSC until such time as The Authority decides otherwise.
