The Mona Offshore Wind Farm (Correction) Order 2025
Published: Tue 28th Oct 25
The Mona Offshore Wind Farm (Correction) Order 2025 formally amends the original development consent order granted for the Mona Offshore Wind Farm under the Planning Act 2008.
This Order, made by the Secretary of State following a request from the applicant, addresses specific correctable errors and omissions within the original Order by substituting, inserting, or omitting text detailed in the accompanying Schedule.
It comes into force on October 24, 2025, ensuring that the existing planning permissions reflect the intended legal provisions regarding technical definitions, consent procedures, environmental considerations, and rights of way relating to the wind farm development.
Arguments For
Ensures legal accuracy and clarity within the development consent order for the Mona Offshore Wind Farm, minimizing ambiguity for implementation.
Upholds the statutory requirement under Schedule 4 of the Planning Act 2008 to correct technical errors and omissions reported by the applicant.
Facilitates the proper execution of the authorized project by providing definitive wording and references, which supports compliance with planning conditions.
Arguments Against
Introducing corrections late in the process may cause minor delays or require re-evaluation of documents that relied on the original, uncorrected wording.
The need for multiple correction orders suggests potential shortcomings in the initial scrutiny or drafting process of the original development consent order.
Any structural or substantive change, even if correcting an error, adds complexity to tracking the finalized legal instruments governing the offshore wind farm.
The Mona Offshore Wind Farm Order 20251 (“the Mona Offshore Wind Order”), which granted development consent within the meaning of the Planning Act 20082 (“the Act”) contains correctable errors within the meaning of paragraph 1 of Schedule 4 to the Act.
In accordance with paragraph 1(5)(a) of Schedule 4 to the Act, before the end of the relevant period3, the Secretary of State received a written request from the applicant4 for the correction of errors and omissions in the Mona Offshore Wind Farm Order.
In accordance with paragraph 1(7) of Schedule 4 to the Act, the Secretary of State has informed each relevant local planning authority 5 for the area in which the land to which the Mona Offshore Wind Farm Order relates is situated that the request has been received.
The Secretary of State in exercise of the powers conferred by paragraphs 1(4) and (8) of Schedule 4 to the Act makes the following Order.
The foundation of this legislative document is the confirmation that the original Mona Offshore Wind Farm Order 2025 contains correctable errors, as defined under the Planning Act 2008.
The Secretary of State received a formal written request from the project applicant to fix these mistakes and omissions before the legally stipulated deadline.
Furthermore, the relevant local planning authorities, whose areas contain the land affected by the Order, have been notified about the receipt of this correction request.
The Secretary of State now exercises powers granted under the Act to issue this corrective Order.

The Schedule provides the exhaustive list of required amendments referenced in Article 2, all relating to changes, insertions, or omissions in the original Order.
These corrections cover several key regulatory and technical aspects.
Changes involve redefining terms like "gravity base" to "gravity base foundation," and adding clarifying words ("spring") to tidal definitions.
Significant revisions update cross-references for development control, such as adding conditions regarding tree preservation orders and modifying requirements related to consultation on radar mitigation schemes in Schedule 2.
Furthermore, the definitions concerning air traffic service (ATS) operators and mitigation schemes related to Warton Aerodrome are updated, including the correction of BAE Systems' registered office address.
Numerous textual and paragraph number changes are made across Schedules 2, 8, 9, and 10, primarily adjusting clause references (e.g., replacing '8' with '23' or '92') and updating document reference numbers and associated dates regarding environmental and scoping documents in Schedule 15, Table 7.
