Longfield Solar Farm Amendment reshapes development consent obligations in UK health and safety law and what this means for regulatory compliance

What has changed

The Longfield Solar Farm (Amendment) Order 2026 amends the Longfield Solar Farm Order 2023, a development consent order under the Planning Act 2008. The amendment affects article 2, article 6, Schedule 1 and part 2 of Schedule 2, altering the scope or conditions previously set out in the 2023 Order. The summary provided indicates changes to governance, conditions and implementation provisions for the project, without detailing every specific provision in this update.

Why this matters

For duty holders this update signals a need to reassess how safety and regulatory compliance are integrated into project governance. Changes to development consent conditions can influence who is responsible for implementing safety arrangements, how scope changes are managed and how HSE considerations intersect with planning requirements. Organisations may face new reporting, site management and contractor oversight expectations. In practice, this reinforces the importance of robust health and safety management alongside planning compliance. Synergos Consultancy supports ongoing regulatory compliance through ISO 45001 occupational health and safety management to help establish systematic risk control.

What organisations should do next

Consider the following actions to align with the amended order and preserve strong HSE standards:

• Obtain and review the amendment to identify new or altered obligations that affect governance and site safety.
• Update risk assessments and method statements to reflect any changes in scope or conditions and ensure alignment with UK health and safety law and HSE requirements.
• Revise the construction phase plan, site rules and permit to work controls as needed.
• Revisit contractor and subcontractor management to confirm competency, induction and ongoing supervision for safe operations.
• Engage workers and their representatives to communicate changes and gather feedback on safety implications.
• Ensure governance and assurance arrangements are in place, including competent person oversight. Where needed, consider Competent Person support.
• Align health and safety management with ISO 45001 and review training needs and monitoring mechanisms. See health and safety training and ISO 45001.

Progress should be tracked through updated governance documentation, regular site inspections and clear lines of accountability to demonstrate compliance with the amended development consent and ongoing HSE requirements.

Compliance messaging and practical steps should be targeted at management teams, site supervisors and safety professionals to ensure swift integration into existing risk controls and reporting frameworks. Synergos can provide tailored support to help embed the update within your management system and risk control processes.

Wrap-up

The Longfield Solar Farm Amendment highlights how changes to development consent can have broad implications for health and safety governance on energy infrastructure projects. Timely alignment of policies, risk assessments and contractor management is essential to maintain regulatory compliance and protect workers. Proactive planning and strong leadership in safety management will help ensure a smooth transition through the amended requirements and minimise disruption to project delivery.
