Background of the Local Plan
Drafted to guide development from 2023–2040, the Horsham District Local Plan set targets for housing delivery, sustainable growth and infrastructure investment. Central to its environmental commitments was the Sussex North Offsetting Water Strategy (SNOWS), designed to ensure developments remained water-neutral.
The plan identified strategic housing sites, pledged community facilities and promised to align local policies with broader regional objectives. Expectations were high—until the inspector’s unexpected verdict landed in April 2025.
Why Was the Plan Rejected?
“Constructive and active engagement with neighbours was simply not evidenced.” That single sentence, pulled from the inspector’s interim findings, captures the tone of the dismissal.
- Duty to Cooperate: Communication with adjacent authorities was judged inadequate.
- Water Neutrality Doubts: Heavy reliance on SNOWS left unanswered questions about long-term supply security.
- Soundness Issues: Housing targets and delivery schedules were branded “over-optimistic.”
- Under Section 22 of the Planning and Compulsory Purchase Act 2004, the inspector recommended full withdrawal of the draft plan.
Council’s Response
Horsham District Council immediately lodged a complaint with the Planning Inspectorate and government ministers, arguing that their cooperation efforts were misunderstood. Leaders insist that launching an entirely new plan now would be unrealistic amid regional government reorganisation.
“We have worked tirelessly with partners; this decision does not reflect that collaboration.” — Council leader
Implications for Residents & Developers
- Potential backlog of more than 3,000 homes, many earmarked as affordable.
- Delays to new schools, roads and community health centres.
- Greater uncertainty for developers assessing land viability.
- Residents face prolonged debates over where—and whether—major sites will proceed.
Next Steps
Council officials have outlined three possible routes:
- Seek a fresh examination hearing with additional evidence.
- Rewrite sections on cooperation and water neutrality, then resubmit.
- Collaborate more closely with neighbouring authorities during ongoing governance reforms.
Whichever path they choose, significant time and resources will be required before a new plan can replace the one just rejected.
Conclusion
The Planning Inspectorate’s dismissal has placed Horsham’s future growth strategy under the microscope. Yet the council’s swift pushback demonstrates a determination to secure a legally sound, environmentally responsible roadmap. The coming months will reveal whether compromise, revision or a wholesale reset is on the horizon.
FAQs
Why was the Horsham District Local Plan rejected?
The inspector found legal non-compliance with the duty to cooperate and inadequate evidence of water neutrality, deeming the plan unsound overall.
What is SNOWS and why does it matter?
The Sussex North Offsetting Water Strategy (SNOWS) is Horsham’s proposed method for ensuring new developments do not increase water consumption. The inspector said SNOWS lacked sufficient evidence, making it a key sticking point.
Will housing projects now be halted?
Many sites will face delays until a compliant plan is in place, though smaller schemes may proceed under existing policies.
How can residents stay informed?
Regular updates are published on the Horsham District Council website and via council social-media channels. Public consultations will also be advertised locally.
Could the decision be overturned?
Yes. If the council submits compelling evidence or revisions, the Planning Inspectorate could reopen hearings or accept a new draft.
