Horsham Plan Collapse Sparks Urgent Review Amid Developer Concerns

Council Response

Horsham District Council expressed *deep disappointment* with the inspector’s findings. A spokesperson stated, “We are profoundly concerned by this decision, which overlooks the complexities of our district.” The council has filed a formal complaint with the Planning Inspectorate requesting a review of both the findings and the process itself, as reported by Local Government Lawyer.

Key Reasons for Rejection

The planning inspectorate highlighted three critical failings:

• Procedural Shortcomings — inadequate evidence of collaboration with neighbouring authorities.
• Environmental Concerns — insufficient water-management policies and risks to protected habitats.
• Legal Non-Compliance — failure to satisfy national sustainability requirements.

These deficiencies led the inspectorate to recommend the plan’s withdrawal rather than modification.

Environmental & Water Issues

A central point of contention was the Sussex North Offsetting Water Strategy (SNOWS), designed to achieve *water neutrality*. Inspectors deemed the strategy “uncertain and unproven,” particularly regarding its capacity to safeguard Pulborough Brooks, a site of special scientific interest.

• Offsetting measures lacked credible evidence for long-term effectiveness.
• Potential impacts on rivers and wetlands raised alarms among environmental groups.

The decision signals a heightened commitment to rigorous ecological standards in future plans.

Impact on Housing

The rejection places Horsham’s housing pipeline *on hold*:

• Developers face uncertainty, delaying both market and affordable homes.
• Regional housing targets could be missed without an approved strategy.
• Residents fear upward pressure on prices amid restricted supply.

Duty to Cooperate

The inspectorate concluded Horsham had not engaged “actively, constructively or on an ongoing basis” with neighbouring districts, breaching the statutory duty to cooperate.

“Failure to demonstrate effective cooperation represents a fundamental deficiency that cannot be remedied through minor edits.” — Inspector’s letter

Next Steps

The council must choose between withdrawing the plan for a complete rewrite or attempting targeted modifications. Either path involves:

• Collecting robust evidence to prove water neutrality.
• Re-engaging with neighbouring authorities to satisfy the duty to cooperate.
• Scheduling renewed examination hearings, likely in late 2025.

Council leaders have called the inspectorate’s expectation of a rapid turnaround **“unrealistic.”**

Wider Implications

Planning professionals view the decision as a warning:

• Future local plans will face tougher environmental scrutiny.
• Early, documented cooperation with neighbouring councils is now essential.
• Legal compliance is non-negotiable, even where housing demand is acute.

Conclusion

Horsham’s local plan rejection represents a significant hurdle. Balancing housing need with environmental protection and legal obligations will shape the next draft. The council’s determination is clear, but a complex, closely watched journey lies ahead.
