Navigating Biodiversity Net Gain in Derbyshire: Top Tips & Strategic Guidance for Developers
Navigating the statutory 10% Biodiversity Net Gain (BNG) mandate requires early planning and strategic execution. Mistakes made early in the design phase can lead to costly project delays, expensive land allocations, and unforeseen Spatial Risk Multiplier (SRM) penalties.
Use this guidance document to de-risk your project, minimize BNG expenditure, and streamline your Local Planning Authority (LPA) approvals.
1. Engage a Qualified Ecologist Before You Draw the Blueprint
- The Trap: Designing a site layout before assessing the baseline ecology often results in accidental destruction of high-value habitats (like mature scrub or ancient hedgerows). Replacing these on-site or buying off-site credits for high-value habitats is exceptionally expensive.
- The Tip: Bring an ecologist to the site during the due diligence phase before purchase or final design. Knowing the baseline score allows your architects to design around high-value ecological areas, saving you thousands in BNG liabilities.

2. Strictly Follow the Mandatory Mitigation Hierarchy
- The Trap: Assuming you can simply build over everything and "buy your way out" with off-site units. LPAs will reject planning applications that use off-site units as a first resort.
- The Tip: You must legally demonstrate that you attempted to Avoid impact first, Minimise impact second, and Rehabilitate on-site third. Off-site BNG units should only be targeted for the remaining deficit that cannot be physically achieved on-site.
3. Factor in the True Cost of On-Site BNG Maintenance
- The Trap: Allotting significant portions of your redline boundary to high-tier on-site habitats (e.g., creating a wildflower meadow next to housing) to hit your 10% target on paper.
- The Tip: Remember that any on-site habitat used to achieve your 10% BNG target must be legally maintained and monitored for a minimum of 30 years. If residents walk dogs over it, or if it reverts to weeds, you are legally liable. For complex or high-maintenance units, it is often more cost-effective to pass that 30-year liability to a dedicated off-site provider like Wild BNG.
5. Secure Your Units Early to Avoid Project Delays
- The Trap: Waiting until you receive planning approval to look for BNG units. High-demand units (like specific woodland or wetland Tiers) can face localised supply shortages.
- The Tip: You cannot discharge your BNG planning conditions until your units are officially allocated and registered. Engage Wild BNG as soon as your Statutory Biodiversity Metric calculation is drafted. We can reserve or broker the exact units you need early, ensuring your project breaks ground on schedule.
4. Minimise Your Spatial Risk Multiplier (SRM) Penalties
- The Trap: Sourcing off-site BNG units from national land brokers without checking where the habitat bank is physically located.
- The Tip: The statutory Defra metric penalises you financially if you buy units outside your local area. Buying units outside the developments LPA or its neighbouring LPAs slashes the value of those units significantly, meaning you have to buy significantly more units to satisfy your deficit. Always prioritise sourcing units locally to keep your procurement costs as low as possible.
