Background & Context
The Horsham District Local Plan sets out where and how new homes, infrastructure, and community facilities should emerge between 2023 and 2040. It is the policy compass guiding land-use decisions, ensuring local projects align with national planning law.
Core components include housing allocation, environmental safeguards, economic growth, and essential infrastructure. Yet the recent Planning Inspectorate verdict has abruptly halted the journey of this crucial document.
Rejection Details
In an interim findings letter dated 4 April 2025, Inspector Luke Fleming ruled the plan both “legally non-compliant” and “unsound,” forcing immediate withdrawal under section 22 of the Planning and Compulsory Purchase Act 2004.
- Examination hearings scheduled for later in the year were cancelled.
- Key legal flaws centred on the Water Neutrality Strategy and insufficient duty-to-cooperate evidence.
Council Response
Council Leader Martin Boffey voiced frustration, stating, “Preparing a new plan quickly is unrealistic, especially amid local government reorganisation.” The authority has contacted the Planning & Housing Minister and lodged a formal complaint with the Planning Inspectorate to trigger a fresh examination.
Officials argue that the duty to cooperate—an obligation under the 2004 Act—was misinterpreted during inspection. Their stance is detailed in coverage by Local Government Lawyer.
Key Issues Highlighted
1. Water Neutrality Strategy
The Sussex North Offsetting Water Strategy (SNOWS) aimed to balance extra demand but was criticised as legally fragile. Inspectors doubted its capacity to offset consumption in an already water-scarce region.
- Effectiveness of offsets remains unproven.
- Risk of non-compliance with environmental regulations.
2. Engagement with Neighbouring Authorities
Inspectors found collaboration “neither constructive nor active,” directly breaching the duty to cooperate. Limited evidence of joint housing or infrastructure planning undermined the plan’s credibility.
Implications for Future Planning
Without an approved plan, developers face a policy vacuum, while the council must re-draft under tighter scrutiny. Future iterations are expected to:
- Demonstrate robust water neutrality proofs.
- Forge formal agreements with neighbouring councils.
- Balance urgent housing demand against environmental limits.
Current Status of Development Projects
Multiple housing and infrastructure applications are on hold. Developers lack clarity on acceptable design density, environmental requirements, and infrastructure contributions, creating an investment chill across the district.
Residents, too, feel the pinch: delays to new community facilities and affordable housing exacerbate local frustration.
Conclusion
The rejection of Horsham’s local plan places the district at a crossroads. Addressing legal compliance, strengthening regional partnerships, and proving water neutrality are non-negotiable steps toward a viable blueprint. Transparent dialogue and regional collaboration will be decisive in shaping a plan that satisfies inspectors while reflecting community needs.
