Details of outcome
We received 14 responses to the consultation, 13 of which were from individual network companies and one from Future Energy Networks (on behalf of the gas network companies). None of the responses were marked as confidential. Most respondents were supportive of the need for the redaction policy to be revised and standardised. Comments were made regarding policy scope, non-disclosure agreements (NDAs) and other proposed changes to the policy. A summary of the consultation responses and our reply to them can be found in Appendix 1.
