To count towards the proven Five Year Housing Land Supply, planning approval must refer to land that meets certain criteria. These criteria include deliverability, suitability, availability, achievability, and compliance with the National Planning Policy Framework (NPPF). Ensuring these criteria are met is essential for maintaining a robust and effective housing supply strategy that balances development needs with community and environmental considerations. This ensures that proposed developments are realistic, viable, and beneficial for both the local area and the wider region.
