A recently tabled UK Government bill — the Planning and Infrastructure Bill 2025 — has prompted concern among ecologists and nature organisations over proposed changes to how ecological requirements will apply in planning applications. While government ministers argue the reformed regime will speed up delivery of infrastructure and housing, critics say parts of the Bill risk eroding environmental protections without sufficient safeguards.
What the Bill Seeks to Change
Under the Bill, developers will have access to new mechanisms such as a Nature Restoration Fund (NRF), which they may use in lieu of some site-based environmental obligations. Part 3 of the Bill introduces Environmental Delivery Plans (EDPs), intended to identify environmental challenges early and enable more strategic mitigation or compensation across projects. Government claims include speeding up major infrastructure decisions and reducing regulatory gridlock.
Concerns from the Ecological Sector
The Chartered Institute of Ecology and Environmental Management (CIEEM) has been among the most vocal critics. While welcoming the idea of early identification of environmental challenges, CIEEM describes the current draft of the Bill as “critically flawed.”
Some of their key concerns include:
- Regression of protection levels
- Uncertainty introduced by EDPs
- Absence of the mitigation hierarchy in some provisions
- Timing of ecological compensation/enhancement
Government Justification & Responses
Ministers defend the Bill by pointing to the need to accelerate delivery of homes and infrastructure, which they argue is being held back by regulatory delays. They assert the Bill will deliver a “win-win”, supporting nature recovery alongside economic growth, and that environmental obligations will not be weakened.
However, the Government’s own impact assessment acknowledged that there is “very limited data” on how many current environmental obligations delay development projects, except for nutrient neutrality obligations.
What This Means for Renewables & Ecological Consultancies
For consultancies working in the renewables sector, these changes could have several implications:
- Greater front-loading of ecological work: Early-stage environmental assessments may become even more critical, as EDPs are intended to pick up nature issues before planning goes too far.
- Potential changes in mitigation options: With more reliance on pooled funds or broader environmental delivery schemes, site-specific mitigation might be less central, altering how renewables projects plan for habitat loss, species disturbance, etc.
- Regulatory risk due to vagueness: Ambiguity in how environmental obligations and protections will work in practice could lead to delays or legal challenges, unless clarity is improved.
- Opportunity & risk in offsetting mechanisms: Where habitat restoration or enhancement is done off-site or via funds rather than strictly on the project footprint, ensuring ecological equivalence and timing will be critical.
Neutral Assessment & Points for Improvement
While the intention behind many proposals — reducing delay, delivering nature recovery at scale, better alignment across environmental plans — is understandable, the concerns raised suggest that without strong legal safeguards, there is real risk that ecological outcomes will suffer.
CIEEM has proposed amendments to tighten the Bill, including ensuring the mitigation hierarchy is preserved in primary legislation; guaranteeing that compensation/enhancement must occur before or concurrent with damage; and clearer definitions and accountability around EDPs.
Looking Ahead
The Bill is continuing through Parliament, and there remains opportunity for revisions. For stakeholders in ecology and renewables, the coming stages (committee, Lords, amendments) will be particularly important. Engaging with MPs, scrutinising proposed changes to Part 3 (and provisions around EDPs and the NRF), and advocating for legally binding protections seem crucial to avoid adverse unintended consequences.
