Environmental delivery plans and the nature restoration fund

An environmental delivery plan is a mechanism for taking one environmental problem away from individual applications and dealing with it at the scale of an area. Natural England prepares the plan for a named environmental feature across a defined geography, the Secretary of State approves it if satisfied that the conservation measures will outweigh the negative effect of the development covered, and a developer within that area can pay a levy into the nature restoration fund instead of providing site-specific mitigation for that feature.

Before relying on any of it, check two things. Whether the relevant provisions are in force on legislation.gov.uk, and whether a plan has actually been made for your feature and your area. The framework exists in legislation taken through Parliament from March 2025, and much of the detail sits in regulations and in the plans themselves, so the position has to be stated as at a date and verified at the time you write your submission. As at the time of writing, nothing replaces the existing route on a site unless a plan covering that feature and area is in place.

The problem the approach is meant to solve

Four categories of constraint have been holding up housing in particular areas, and all four have the same shape. An impact that is small from one scheme, significant in aggregate, and expensive to address site by site.

Nutrient neutrality in catchments where a protected habitats site is in unfavourable condition for nitrogen or phosphorus. Water neutrality where abstraction affects a designated site. Recreational disturbance to coastal and heathland sites, where mitigation has been delivered through visitor management and alternative greenspace. And protected species, where individual licensing has given way in places to a district level approach, as with the great crested newt licensing scheme Natural England has run for several years.

In each case an appropriate assessment under the Conservation of Habitats and Species Regulations 2017, or a species licence, has to be resolved before permission can be granted or before works begin. The site-by-site version of that exercise produces a market in credits, long negotiations and, on smaller sites, a cost per dwelling that can be decisive.

What an environmental delivery plan would cover

Each plan is specific rather than general. It identifies the environmental feature it addresses, the geographic area it applies to, the categories of development it covers, the conservation measures that will be delivered, who will deliver them and when, and the charging arrangements for the levy.

That specificity matters for a developer. A plan covering nutrients in one catchment does nothing for recreational disturbance in the same catchment, and a plan covering residential development may not cover commercial. Read the scope of the plan rather than assuming the mechanism is general.

The plans are also time-limited and reviewable, with monitoring built in, so the measures can be adjusted if they are not working. For a scheme with a long build programme, that means the arrangements applying at the point of payment are what matter rather than the arrangements when the plan was first approved.

How a payment replaces site specific mitigation

The structure is straightforward. Where a plan covers the feature and the development, the developer may commit to pay the levy, and that commitment discharges the obligation that would otherwise require site-specific mitigation for that feature. The authority can then grant permission without the assessment it would otherwise have needed on that issue.

Three details decide whether this is better for a scheme than the existing route:

• the rate, which is set out in the plan's charging arrangements rather than negotiated, and which may vary by development type and location
• the payment timing, which determines whether the cost sits before or after receipts
• the breadth of the discharge, because a payment covering nutrients still leaves every other environmental obligation in place

Compare that against what you would otherwise pay. In an established nutrient catchment with a functioning credit market, the existing route may cost less or complete faster on a particular site, and the levy may not be the better answer simply because it is newer.

The conservation measures and the overall improvement test

Approval depends on the Secretary of State being satisfied that the conservation measures are likely to outweigh the negative effect of the development on the identified feature. That is the test the plans have to pass, and it is the part of the mechanism that has attracted most debate, because it works at the level of the feature and the plan area rather than at the level of the individual site.

The argument against is that an impact can occur before the compensating measure matures, and that the aggregate test is less protective than the site-level test it replaces. The argument for is that the site-level test has not delivered improvement either, since mitigation sized to offset harm is not designed to improve condition.

Both arguments have force, and the practical question for a developer is narrower. Does the plan covering your site give you a discharge that a lender and a planning authority will both accept? That depends on the plan's drafting and on the regulations, not on the policy debate.

Which obligations remain unaffected

This is where applicants get caught, so treat the list as a checklist rather than a summary.

Biodiversity net gain under the Environment Act 2021 is a separate regime and is not discharged by a levy payment. The statutory metric still has to be completed by a competent person and the biodiversity gain plan still has to be approved by the authority, which makes the Biodiversity Net Gain Assessment a report type where a competent person is legally required and an AI-assisted draft is a starting point for that person rather than a substitute. The mechanics of the gain condition are set out in how the biodiversity gain condition is deemed into a permission.

Environmental impact assessment obligations continue, as do protected species offences and the need for a licence where the species or activity falls outside the plan's scope. Features not named in the plan are unaffected, so a site within a nutrient plan area that also lies near a designated heathland still has to address recreational disturbance by the existing route. And irreplaceable habitats sit outside the gain regime entirely, which the exception for irreplaceable habitats explains.

Local plan policies on green infrastructure, trees and open space also continue to apply, and an authority may still require ecological survey work to inform design even where the headline constraint is dealt with by a payment. The Preliminary Ecological Appraisal is a report councils expect from a suitably qualified author, and professional review is strongly advised whatever the funding mechanism.

Coverage, timing and the as at position

Three questions to put to Natural England or to the authority on any affected site, in writing:

1. Is there an approved environmental delivery plan covering this feature and this area, and if not, is one in preparation and on what timetable?
2. What are the charging arrangements, and when does payment fall due relative to permission and to occupation?
3. What exactly does a payment discharge, and what remains to be addressed?

Keep the replies. A scheme that is programmed around a plan that has not been made yet is exposed, and the honest answer on many sites in the near term is that the existing route has to be kept live as the primary option.

What to do on a scheme now

Run both routes in parallel until one is clearly better. That means keeping the credit purchase or on-site mitigation option open, with a quotation and a programme, while tracking whether a plan is coming for your area.

Then build the comparison into the appraisal as two scenarios rather than one line, with the timing of payment modelled in each. On a phased scheme the comparison may land differently for different phases, because a plan made during the build programme can change the position for later phases.

And resist designing out ecological value on the assumption that a payment covers it. Authorities read that, members react to it, and the gain regime will require the units anyway. Reform in this area continues to move, so the planning law timeline is the place to follow it, and the position set out here should be verified against the current legislation and the published plans before it informs a decision.

This is general guidance, not legal advice. Check the position with your local planning authority, with Natural England or with a qualified professional before relying on it.
