Background on the Horsham District Local Plan
The Horsham District local plan was crafted to steer development from 2023 to 2040, focusing on meeting government-set housing targets, bolstering infrastructure, and ensuring water neutrality through the Sussex North Offsetting Water Strategy (SNOWS). Its ambition was to balance rapid growth with environmental stewardship in a region already battling water scarcity.
Why Was the Plan Rejected?
The Planning Inspectorate cited several critical shortcomings:
- Legal non-compliance: The draft failed to satisfy statutory duties under the Planning and Compulsory Purchase Act 2004.
- Duty to cooperate: Engagement with neighbouring authorities was neither “constructive nor active,” undermining cross-boundary planning.
- Soundness concerns: Housing delivery estimates were viewed as overly optimistic, with unresolved dependencies threatening feasibility.
- Water neutrality: SNOWS lacked credible evidence that development would not worsen regional water stress.
Role of the Planning Inspectorate
Inspector Luke Fleming issued interim findings in April 2025, recommending immediate withdrawal. His report stated, “The draft plan is legally non-compliant, and engagement with neighbouring authorities was neither constructive nor active.” Formal hearings, which began in December 2024, were swiftly cancelled once these fundamental flaws emerged.
Council’s Response
Councillor Martin Boffey, leader of Horsham District Council, described the outcome as “hugely disappointing,” alleging the process reflected unfair policy changes. The council submitted a formal complaint to the Planning Inspectorate and the Planning & Housing Minister, arguing that evolving national guidance had moved the goalposts. A detailed review will proceed through Cabinet and Scrutiny Committees ahead of an August 2025 debate on formal withdrawal.

Implications for Planning & Governance
- Housing Delivery: Uncertainty looms over upcoming developments, risking delays in meeting both local and national targets.
- Government Reorganisation: Possible structural reforms could compound timetable pressures for drafting a new plan.
- Water Strategy Gap: The failure of SNOWS leaves developers without clear guidance on sustainable water use.
Next Steps & Future Outlook
Horsham District Council must now produce a fully revised plan addressing legal compliance, realistic housing delivery, stronger cooperation, and a credible water neutrality framework. Officials anticipate the rewrite could stretch into late 2026 or beyond, requiring intensive stakeholder engagement and rigorous environmental assessment.
Impact on Residents
Residents face ongoing uncertainty over housing availability, infrastructure upgrades, and community amenities. As one local business owner noted, “We’ve planned to expand for years, but every delay pushes investment further into the future.” Until a compliant plan is adopted, families and enterprises alike may struggle to chart their own futures in Horsham.
Conclusion
The Planning Inspectorate’s rejection marks a pivotal juncture for Horsham. Addressing the legal, cooperative, and environmental shortcomings unveiled in this process is essential to restore confidence and unlock much-needed housing and infrastructure. The coming months will test the council’s ability to craft a plan that is both legally robust and environmentally sustainable—an effort that will shape Horsham’s trajectory for decades.
FAQs
Why did the Planning Inspectorate dismiss the Horsham local plan?
Key reasons included legal non-compliance, failure to cooperate with neighbouring authorities, questionable housing delivery figures, and insufficient evidence of water neutrality.
What is the Duty to Cooperate?
It is a legal requirement compelling councils to engage actively and constructively with neighbouring authorities on cross-boundary issues like housing and infrastructure. The inspector found Horsham’s efforts lacking.
How long will it take to create a new plan?
Council officials anticipate a full rewrite could extend into late 2026 or beyond, given the need for fresh evidence, consultations, and environmental assessments.
Will housing projects halt in the meantime?
Not entirely, but many proposals may face delays or additional scrutiny until a compliant strategic framework is in place.
What happens if the council fails again?
Repeated failure could invite central government intervention, potentially leading to an externally imposed plan or other corrective measures.
