National Grid Ventures states on its Nautilus project page (updated July 2025) that environmental and technical surveys in the Isle of Grain area are expected to begin from autumn 2025, using non-intrusive and intrusive methods to inform site design. The projection is for survey mobilisation in autumn 2025 rather than a specific day, so 1 September 2025 is used as an approximate start-of-autumn marker.
