Norfolk EDP: new £2,675 levy could unlock 15,780 homes

The first draft Norfolk EDP proposes a £2,675 levy per house or flat, before indexation and any VAT, to help address the nutrient pollution holding up housing development. Natural England says the plan could support up to 15,780 homes while funding improvements to rivers and wetlands.

Announced on 17th September 2026, this is the first draft Environmental Delivery Plan under the Nature Restoration Fund to reach consultation. The consultation closes at 9.29 am on 27th October 2026.

For developers, the attraction is a more predictable payment and a strategic programme delivered by Natural England. However, the Norfolk EDP is not yet available to use. Its boundaries, exclusions, drainage requirements and proposed payment arrangements all need checking before treating it as an answer for a particular site.

What does the Norfolk EDP actually cover?

The draft Norfolk Environmental Delivery Plan addresses nutrient pollution from wastewater and surface-water runoff associated with dwellinghouses, including flats. It concerns specified protected features of the Broads Special Area of Conservation, Broadland Ramsar wetland and River Wensum Special Area of Conservation.

The development area is based on three catchments:

This is not a county-wide scheme. Ant Broads and Marshes, Trinity Broads and Upper Thurne Broads and Marshes are expressly left out of this draft because of the limited development coming forward in their catchments.

Some wastewater treatment catchments extend the mapped area beyond the surface-water catchments. A site’s foul sewage destination can therefore matter as well as where rainwater drains. The map and the proposed drainage arrangements need to be read together.

Which councils and development areas are affected?

The draft identifies affected areas within South Norfolk, Broadland, Norwich, Breckland, North Norfolk, King’s Lynn and West Norfolk, and the Broads Authority. The proportion of each authority’s area covered varies considerably.

The mapped area takes in Norwich and parts of central and eastern Norfolk. Being in one of the named council areas does not establish eligibility. The development-area map on page 18 of the draft, the exclusions and the drainage connections are the starting point for a site appraisal.

The Norfolk EDP excludes the specified protected-site land itself and a 50-metre buffer around the Bure and Yare Broads and Marshes sites and River Wensum SAC. A development site falling wholly or partly within that buffer cannot use this plan. This is a restriction on the development site, not simply a setback for a drainage outfall.

How would a developer use the levy?

Participation would be voluntary. For an eligible proposal, the intended process is:

1. Check that the final EDP is in force and covers the development, its location and the relevant environmental effects
2. Obtain an indicative levy quote and request to use the scheme
3. Receive a commitment certificate if Natural England accepts the request and has sufficient capacity
4. Submit that certificate as part of the planning application
5. After planning permission is granted, assume liability for the levy and receive the liability notice
6. Pay the levy in full, or the first instalment under an available instalment arrangement, before starting development

A quote does not reserve capacity. Natural England’s acceptance of the request does. The commitment certificate and capacity rules also include a six-month expiry where the commitment is not followed by a planning application.

The distinction between commitment and payment matters. A valid commitment under an applicable EDP allows the specified environmental effects to be disregarded for the relevant Habitats Regulations assessment. The later payment requirement is secured through the statutory condition preventing commencement until the levy, or the first instalment, has been paid.

The process above describes the ordinary planning application route. General consents, including relevant permitted development routes, have separate procedural provisions in the regulations.

What would the Norfolk EDP cost?

The proposed charge is £2,675 for each house or flat, with annual indexation linked to the RICS Community Infrastructure Levy Index. It is a flat charge per unit, rather than a charge based on each development’s calculated nutrient-credit requirement.

For example, the proposed base levy for ten homes would be £26,750 before indexation and any VAT. The draft developer-process supplement says levy amounts exclude VAT, charged at 20%. That statement appears in illustrative draft paperwork, so applicants should check the final charging documentation before fixing a budget.

Instalments are provided for in the regulations, but the Norfolk supplement’s example is expressly illustrative. It still contains an unspecified qualifying threshold and an additional charge to be confirmed. It should not be treated as a settled offer of three equal payments.

The nature restoration levy would be separate from planning application fees and any other applicable development costs.

Who would deliver the environmental improvements?

Natural England would use the levy to secure a strategic programme of conservation measures, working with landowners and delivery partners. The proposed programme includes wetland creation and restoration, changes in land management, fen management and work to restore the River Wensum.

Examples include 109 hectares of fen-type wetland creation or restoration across the Bure and Yare, and removal or modification of a river structure alongside one kilometre of Wensum river restoration. The draft also includes deer management and habitat creation for Desmoulin’s whorl snail.

The money would support delivery, administration, monitoring and long-term maintenance. The draft proposes securing conservation measures for at least 100 years, with maintenance where required. Monitoring, back-up measures and amendments are intended to address underperformance.

This approach differs from simply purchasing an equivalent quantity of nutrient reduction. Measures may reduce pollution, improve habitat condition or make the specified habitats and species more resilient. The statutory test applies to the conservation status of each identified environmental feature: by the EDP’s end date, the conservation measures’ positive effects must materially outweigh the negative effects of the maximum development it covers. The plan must also explain how measures will be maintained for as long as they are likely to be needed to address the development’s impacts.

Natural England considers its draft meets that test. That assessment is part of what consultees can scrutinise. It does not establish that every restoration project would be completed before housing starts, or that the plan would remove all existing agricultural and other background pollution.

What obligations would stay with the developer?

The Norfolk EDP would provide an alternative route for its specified nutrient impacts. It would not grant planning permission or remove requirements concerning other environmental effects. Our Habitats Regulations Assessment guide explains why the particular protected features and effects matter.

The draft also proposes a site-level condition for non-mains foul drainage. Before occupation, a package treatment plant would need to be installed and operating with discharge concentrations no higher than 5 mg/l total phosphorus and 27 mg/l total nitrogen. That performance would have to be maintained for the development’s lifetime.

Applicants outside the scheme, or choosing not to participate, would still need an appropriate route through the existing nutrient neutrality and Habitats Regulations requirements where those apply. The announcement does not remove those requirements today.

What is law, and what is still a proposal?

Some references in the consultation pack and the earlier Government guidance still link to the draft levy regulations. The final Nature Restoration Levy Regulations 2026 are now the relevant instrument. That does not turn the draft Norfolk EDP into a live plan.

Does this really unlock 15,780 homes?

15,780 is the draft’s modelled maximum capacity. It is not a schedule of homes granted permission or a guarantee of completions. The calculation uses catchment housing need, an assumed 75% delivery rate and an assumed 80% take-up of the Nature Restoration Fund route.

The Norfolk EDP is proposed to run for ten years, but new requests to pay the levy would close at the end of year six. This gives Natural England time to deliver the conservation measures before the plan ends. The actual start and end dates remain blank in the draft, pending the Secretary of State’s decision.

Because participation is voluntary, the capacity is not a ceiling on every home that could be built in the area. Other acceptable mitigation routes could still support additional development.

What should developers and consultants do now?

For a stalled housing proposal, this is a reason to review the options. It is not yet a reason to abandon an available mitigation solution or promise a client a start date.

1. Check the mapped boundary, the 50-metre exclusions and both foul and surface-water drainage routes
2. Compare the proposed levy, indexation, potential VAT and payment timing with the cost and programme of existing mitigation options
3. Identify any environmental effects and planning requirements that the EDP would leave unresolved
4. Use the consultation to raise site-specific eligibility, drainage, charging or delivery concerns
5. Confirm the made plan, operational start date and available capacity before relying on the route in an application

The Norfolk EDP consultation opened at 9.30 am on 17th September 2026 and closes at 9.29 am on 27th October 2026. Responses received after 9.29 am will not be counted.
