- Baseline biodiversity calculation We calculate current biodiversity units using DEFRA metrics.
- Mitigation and enhancement strategy We propose habitat improvements to achieve required net gain.
- BNG report preparation A full planning‑ready report is produced with all calculations.
- Submission & liaison We provide the BNG report to your architect or submit it with your planning application.

A fixed quote is provided after reviewing your site and drawings.
Borough‑specific considerations
BNG requirements vary between councils. We specialise in:
- London boroughs — strict urban greening and habitat enhancement policies
- Kensington & Chelsea — limited green space, high scrutiny on planting
- Westminster — urban greening factor (UGF) integration
- Camden — biodiversity corridors and ecological connectivity
- Lancashire authorities — rural habitat protection and enhancement
- Conservation areas — sensitive planting and habitat retention
Your BNG strategy is tailored to your borough’s ecological policies.
Common mistakes to avoid
Applications are often delayed or refused when:
- No BNG assessment is submitted
- The BNG report uses outdated DEFRA metrics
- Habitat calculations are incorrect
- Mitigation measures are unrealistic or uncosted
- Landscaping plans don’t align with BNG requirements
- Developers assume small sites are exempt
Planning World ensures your BNG submission is compliant, accurate, and planning‑ready.
