  • Date 9 March 2026
  • Sector Central government
  • Decision(s) EIR 10: Upheld, EIR 12(4)(a): Not upheld, EIR 9: Not upheld

The complainant has requested bird and bat mortality data associated with wind farms from the Department for Energy Security & Net Zero (DESNZ). DESNZ relied on regulation 12(4)(a) of the EIR because it did not hold the requested information. The Commissioner’s decision is that DESNZ has correctly applied regulation 12(4)(a) as, on the balance of probabilities, it does not hold the information. DESNZ complied with its duties under regulation 9 (advice and assistance) and but breached regulation 10 (transfer of request). The Commissioner does not require further steps to be taken.
