Development blocked by nutrient neutrality

First, verify that nutrient neutrality really is your blocker:

• ☐ Site is within affected catchment boundary (not just near it)
• ☐ Development involves overnight accommodation (residential, hotel, care home)
• ☐ LPA has confirmed nutrient neutrality requirement applies

Option 1: Buy mitigation credits

Natural England Nutrient Mitigation Scheme

• Available in some catchments (Tees, Poole Harbour, others being developed)
• Cost: about £2,700-3,250 per kg of nitrogen (Tees and Poole Harbour catchments; prices are set per catchment and application round and change over time - check the current figures on the relevant gov.uk catchment page before budgeting)
• Simple and certain - once bought, you have proof of mitigation
• Limitation: Not available in all catchments, may have limited supply

Option 2: Private mitigation schemes

• Some private providers offer nutrient credits
• May be available where NE scheme is not
• Due diligence required - ensure scheme is LPA-accepted
• Costs vary - shop around

Option 3: On-site mitigation

• Enhanced wastewater treatment (package treatment plants)
• Constructed wetlands for polishing
• SuDS with nutrient capture
• Requires technical design and ongoing maintenance

Option 4: Land use change

• Convert agricultural land to low-nutrient use (woodland, permanent grassland)
• Must be within same catchment
• Requires long-term management commitment
• May require separate land holding

Option 5: Wait for wastewater upgrades

• Water companies must upgrade treatment works by April 2030
• Once upgraded, developments connecting to that works may not need separate mitigation
• Risk: 4+ years wait, no guarantee it solves your specific catchment

Option 6: The Nature Restoration Fund (coming, not yet live)

• The Planning and Infrastructure Act 2025 (Royal Assent 18 December 2025) creates a Nature Restoration Fund and Environmental Delivery Plans (EDPs)
• In time, you may be able to pay into a strategic fund instead of demonstrating site-by-site neutrality
• Enacted but not yet operational: as of mid-2026 no EDP is in force, so per-site neutrality still applies
• Natural England has notified an intention to prepare nutrient-pollution EDPs, expected to be consulted on during 2026 - check the current position with your LPA

Typical nutrient load for residential development:

• Single dwelling: about 0.8-1.2 kg nitrogen/year
• 10-unit scheme: about 8-12 kg nitrogen/year

At around £3,000 per kg (current Natural England credit pricing), a 10-unit scheme might cost £24,000-36,000 for nutrient mitigation.

1. Contact your LPA: Understand their specific requirements and any local schemes
2. Calculate your budget: Use Natural England's calculator for your catchment
3. Explore mitigation options: Get quotes from NE, private providers, and technical consultants
4. Secure mitigation before application: You need committed mitigation, not just plans
5. Prepare your statement: Document everything in your Nutrient Neutrality Statement
