Environmental Delivery Plans: What Developers Must Know
The introduction of Environmental Delivery Plans (EDPs) under the Planning and Infrastructure Act 2025 marks a significant shift in how environmental obligations may be managed within the English planning system. While the legislation establishes a clear framework, there remains a mix of confirmed detail and emerging uncertainty that developers must carefully navigate.
At Lizard Landscape Design and Ecology, we are closely monitoring these developments to help clients understand both the opportunities and risks associated with this new mechanism.
What Are Environmental Delivery Plans?
Environmental Delivery Plans are now established in law as a formal route to address specific environmental impacts linked to development. In practical terms, EDPs may allow developers to discharge certain environmental obligations through a defined contribution, rather than delivering mitigation measures on a site-by-site basis.
Each plan will set out key parameters, including the environmental impacts covered, the geographic area of application, and the types of development within scope. In addition, EDPs will define the conservation measures to be delivered, the levy payable, and the overall capacity available within the plan.
This structured approach has the potential to streamline elements of the planning process, particularly in areas where environmental constraints are well understood.
What Has Been Confirmed So Far?
The first wave of EDPs is expected to focus on nutrient impacts, reflecting ongoing challenges around nutrient neutrality across many parts of England. There is also a strong indication that protected species, such as great crested newts, will be incorporated into future plans, although the detailed mechanics are yet to be fully clarified.
What is clear is that EDPs are intended to provide an alternative pathway, rather than a complete replacement, for existing environmental mitigation strategies. Developers should therefore expect a hybrid approach to remain in place for the foreseeable future.
What Remains Uncertain?
Despite the legislative foundation, several important aspects of EDPs are still evolving. It is not yet confirmed whether participation will be voluntary or mandatory in most cases, which could significantly influence how developers approach compliance.
There is also uncertainty around how EDPs will interact with existing credit markets, particularly in relation to nutrient mitigation. While EDPs are expected to simplify delivery, the transition from current systems has not been fully defined.
Operational detail is another key unknown. How capacity will be allocated, and how this may impact programme timelines, remains unclear. Similarly, beyond nutrients and certain protected species, there is no confirmed timetable for expanding EDP coverage to other environmental considerations.
What This Means for Developers
Even at this early stage, several strategic implications are emerging. Early site due diligence will become increasingly important, particularly in understanding baseline environmental constraints and the potential applicability of EDPs.
Geographic considerations will also play a critical role, as each plan will operate within defined boundaries. Developers will need to assess whether their sites fall within an EDP area and what capacity may be available.
Cost planning will require careful comparison between levy-based contributions and traditional mitigation approaches. While EDPs may offer efficiencies, they are unlikely to eliminate the need for on-site assessment, ecological input, or planning conditions.
Ultimately, EDPs may simplify certain aspects of environmental compliance, but they will not remove environmental risk from the development process.
Planning Ahead with Confidence
As Environmental Delivery Plans continue to take shape, early engagement and informed strategy will be essential. Understanding how these plans apply to your site and how they interact with existing requirements will be key to maintaining programme certainty and managing costs effectively.
Our team continues to track policy developments and provide clear, practical advice to support developers at every stage of the planning process.
