Horsham’s Local Plan Rejected Big Setback or Strategic Opportunity

Estimated reading time: 6 minutes

Key Takeaways

• The Planning Inspectorate rejected Horsham’s draft Local Plan, citing legal non-compliance.
• Key issues include *water neutrality*, cross-boundary cooperation and protection of sensitive sites like Pulborough Brooks.
• Horsham District Council seeks a fresh hearing and may pursue further scrutiny rather than an immediate judicial review.
• Delays could slow housing delivery, increase costs and disrupt wider regional planning.

Background on the Local Plan

Horsham District Council developed a draft Local Plan as a strategic blueprint to guide growth, improve infrastructure and provide *much-needed* housing. It proposed delivering thousands of new homes while **safeguarding** the district’s rural character.

Central to the plan were ambitious housing targets meant to tackle affordability and meet national supply requirements. Yet the council pledged to balance growth with sustainability, emphasising green corridors, renewable energy and protection of cherished landscapes.

“We aimed for a plan that *meets tomorrow’s housing needs* without sacrificing today’s environment,” a council spokesperson told local press.

Details of the Rejection

Following examination hearings in late 2024, an independent inspector issued interim findings on 4 April 2025, declaring the plan “unsound”. Key criticisms included:

• Inadequate evidence for water neutrality measures.
• Failure to satisfy the *Duty to Cooperate* with neighbouring authorities.
• Insufficient safeguards for development near Pulborough Brooks and other protected habitats.

Council’s Response

The council has *challenged* several findings, claiming the inspector overlooked emerging data on regional water supply and alternative mitigation strategies. While a judicial review remains possible, current emphasis is on revising the plan and requesting a fresh examination.

Officials have also urged parliamentary scrutiny of the decision-making process, suggesting that “locally rooted solutions were discounted in favour of rigid national benchmarks.”

Key Issues Highlighted

• Water Neutrality: The plan lacked enforceable mechanisms to ensure no net increase in water consumption.
• Protected Areas: Proposals near sensitive wildlife sites were deemed *too risky* for biodiversity.
• Duty to Cooperate: Limited collaboration with adjacent councils weakened regional infrastructure planning.

Implications for Future Planning

Delays could exacerbate housing shortages, trigger government intervention and inflate land prices. Additionally, uncertainty may deter investment in critical transport and utilities projects spanning district boundaries.

Administratively, the council faces rising costs to amend environmental studies, consult stakeholders and re-submit documentation—resources that *might otherwise* fund community services.

Next Steps & Potential Outcomes

1. Revise the Local Plan with stronger evidence on water neutrality and cross-boundary housing distribution.
2. Re-open public consultation, inviting input from residents, environmental bodies and neighbouring councils.
3. Submit the updated plan for a new examination, *ideally* by early 2026.
4. If rejection persists, consider phased site allocations or escalating to judicial review.

Conclusion

The inspector’s verdict represents a significant hurdle for Horsham, yet it also offers a *chance* to refine policy and showcase innovative sustainability measures. Success will hinge on **transparent engagement**, robust environmental science and stronger regional cooperation.

FAQs

Why was the Local Plan declared “unsound”?

The inspector cited legal non-compliance, insufficient evidence on water neutrality and inadequate regional cooperation.

What is water neutrality and why does it matter?

Water neutrality ensures new development does not increase overall water demand. It is vital for protecting the Arun Valley’s fragile ecosystems.

Could Horsham District Council pursue a judicial review?

Yes, though the council currently prioritises revising the plan. A judicial review remains a fallback if future submissions fail.

Will housing delivery targets be affected?

Likely. Delays in adopting a sound plan may slow construction starts, pushing completion timelines beyond 2030.

How can residents stay involved?

Residents can attend council meetings, submit feedback during consultations and follow updates on the Local Plan webpage.
