Original call for input

Call for input description

This call for input forms part of early, non-statutory engagement and is intended to help us refine the drafting, structure and operability of the licence conditions before launching a statutory consultation planned for Q2 2026.

We welcome feedback on the full draft, with a particular focus on specific policy areas and drafting points where stakeholder input is most valuable at this stage.

Who should respond

While this consultation is particularly relevant to LDES projects applying under the first application window, we also welcome input from stakeholders, including industry participants, energy experts, and members of the public. 

Your feedback will help us refine the draft special licence conditions ahead of the statutory consultation.
