The Department for Energy Security and Net Zero has made the Mona Offshore Wind Farm (Correction) Order 2025 (S.I. 2025/1123) to rectify errors in the original development consent order for the scheme. The instrument was made on 23 October 2025 and came into force on 24 October 2025.
The Correction Order identifies the Mona Offshore Wind Farm Order 2025 (S.I. 2025/870) as containing correctable errors within the meaning of paragraph 1 of Schedule 4 to the Planning Act 2008. Under Schedule 4, the Secretary of State may amend a development consent order to correct errors or omissions.
The Department records that a written request from the applicant was received before the end of the relevant period, as required by paragraph 1(5)(a) and defined at paragraph 1(6)(a) of Schedule 4. In accordance with paragraph 1(7), each relevant local planning authority for the affected area was notified that the request had been received.
Exercising the powers in paragraphs 1(4) and 1(8) of Schedule 4, the Secretary of State has made the Order. It is signed on 23 October 2025 by John Wheadon, Head of Energy Infrastructure Planning Delivery & Innovation, acting for the Secretary of State for Energy Security and Net Zero.
Article 2 specifies that the corrections are set out in a Schedule structured as a table. Column 1 identifies where the change is to be made in the original Order, column 2 explains how the correction is effected, and column 3 provides the precise text to be substituted, inserted, or omitted.
The Explanatory Note states that the purpose is to correct errors in S.I. 2025/870 following a request made under paragraph 1(5)(a) of Schedule 4 to the 2008 Act. The instrument introduces no new policy; it adjusts the drafting of the existing development consent.
For planning officers and project teams, the effect is immediate. From 24 October 2025 the Mona DCO should be read together with S.I. 2025/1123, and any applications to discharge requirements or approve plans should cite the corrected provisions to ensure administrative consistency.
Developers, contractors, and advisers should check legal descriptions, requirement numbering, and any reproduced text in contracts, management plans, and compliance registers against the Schedule. Local planning authorities should ensure decision notices and monitoring templates reflect the corrected wording.
