Introduction
In a development that sent shockwaves through West Sussex, the Planning Inspectorate has rejected Horsham District Council’s Local Plan. Finalised in April 2025 after tense preliminary hearings, the decision pauses the district’s housing and sustainability blueprint and forces officials back to the drawing board.
Background of the Local Plan
Submitted in July 2024, the draft Local Plan aimed to guide development until 2040. Its twin pillars were robust housing delivery and water neutrality — a commitment underpinned by the Sussex North Offsetting Water Strategy (SNOWS).
- Target timeframe: 2025 – 2040
- Core objectives
- Build sufficient new homes
- Maintain environmental balance through water neutrality
Reasons for Rejection
The examining inspector found the plan legally non-compliant and unsound. Two shortcomings stood out:
- Statutory duty to cooperate was not met; engagement with neighbouring authorities was deemed neither “constructive nor active.”
- SNOWS lacked clear evidence that genuine water neutrality could be delivered.
“Without robust cross-boundary collaboration, the plan fails a fundamental legal test,” the inspector wrote.
Council’s Response
Horsham District Council voiced strong disappointment and swiftly filed a complaint with the Planning Inspectorate while contacting the Planning and Housing Minister.
- Exploring plan withdrawal versus targeted revision
- Re-engaging with neighbouring councils to shore up cooperation evidence
“We believe the inspector’s assessment was unfair and fails to recognise our longstanding commitment to sustainable growth,” said Council Leader Claire Vickers.
Implications for Local Development
The absence of an approved plan fuels uncertainty for residents, developers, and environmental groups alike:
- Potential delay of several thousand new homes
- Greater scrutiny of all water-related planning applications
- Strategic decisions complicated by local government reorganisation
Next Steps
Council officers are preparing for potential re-examination hearings, deepening engagement with neighbouring authorities, and analysing legal avenues. As of April 2025, no firm timeline exists for resubmitting the plan.
A detailed analysis by Local Government Lawyer notes that any fresh submission must convincingly demonstrate both cooperation and water neutrality.
Conclusion
The Planning Inspectorate’s rejection places Horsham’s development strategy at a crossroads. While officials contest aspects of the ruling, they must address cooperation gaps and bolster evidence for water neutrality. The coming months promise intense behind-the-scenes negotiations, and the district’s long-term growth will hinge on how effectively those shortcomings are resolved.
FAQs
What exactly was rejected?
The Planning Inspectorate rejected Horsham’s draft Local Plan — the document that outlines where and how new homes, infrastructure, and environmental safeguards should be delivered through 2040.
Why did the inspector say the plan was unsound?
Key failings included a lack of evidence for genuine water neutrality and insufficient cooperation with neighbouring councils on cross-boundary issues.
How is the council responding?
Horsham District Council has filed a complaint, opened dialogue with central government, and is deciding whether to withdraw, revise, or legally challenge the inspector’s findings.
What does this mean for local housing projects?
Until a new or revised plan is approved, housing schemes may face delays or stricter scrutiny, making timelines and costs less predictable for developers and prospective homeowners.
