The deadlines for data submission for the purpose of issuing Renewables Obligation Certificates (ROCs) and the dates by which Ofgem intends to issue ROCs for the period April 2025 to March 2026.
If an operator has problems submitting ROC output data to Ofgem within the timeframes, we should be notified before the relevant date in Column A. If data for Renewables Obligation Certificates (ROCs) is submitted to Ofgem after the date shown in Column A it will be suspended and Ofgem will look to generators to provide reasons as to why the data was submitted late. In these cases, it is unlikely that ROCs will be issued by the date shown in column B.
Micro-generating stations
Operators of micro-generating stations with a declared net capacity of 50 kW or less (or their agents) that have notified Ofgem that they want ROCs to be issued on an annual basis, must provide data for output and input electricity for the period 1 April 2025 to 31 March 2026 by 31 May 2026 at the latest. Our generator guidance and agent guidance provides more information on this.
For individual micro-generating stations in Northern Ireland we provide detailed instructions in the register user guide. In the majority of cases, data should be submitted via the register.
