Introduction
In a pivotal development for Horsham’s future, the Planning Inspectorate has dismissed Horsham District Council’s local plan. The document, submitted in July 2024 and meant to steer growth until 2040, was found legally non-compliant and lacking proof of *water neutrality*. The council now faces the challenge of revisiting its entire strategy while keeping residents, developers and environmental groups on board. Full details can be found via Local Government Lawyer.
Council Reaction
“We are hugely disappointed,” said council leaders after the rejection. They emphasised their commitment to a *fresh review* of the inspector’s findings and promised greater transparency moving forward.
- The plan covered housing, infrastructure and environmental policy from 2023-2040.
- Officials argue that last-minute national policy shifts raised the bar mid-process.
- An official complaint has been filed with the Planning & Housing Minister.
Inspectorate Decision
Planning Inspector Luke Fleming published interim findings on 4 April 2025, concluding that the council had not met statutory duties or provided credible evidence on water neutrality. Consequently, remaining hearings were cancelled, placing development ambitions in limbo.
“The evidence base does not demonstrate that proposed mitigation will achieve neutrality,” Fleming wrote.
Legal Compliance Concerns
At the heart of the dispute is the Duty to Cooperate under Section 22 of the Planning and Compulsory Purchase Act 2004. The inspectorate claims collaboration with neighbouring authorities was neither “constructive” nor “active.” The council counters that regional reorganisation and shifting guidelines complicated efforts.
Water Neutrality Debate
To tackle groundwater stress, the draft plan introduced the Sussex North Offsetting Water Strategy (SNOWS). However, inspectors dismissed SNOWS as *insufficiently evidenced*. Council officers maintain the rules changed late, likening the experience to “playing football while the goalposts move.”
- SNOWS sought to balance water demand from all new builds.
- Evidence on implementation mechanisms was criticised as weak.
- Revisions must now meet tougher neutrality metrics.
Future Steps
The council will hold Scrutiny Committee then Cabinet sessions to decide whether to formally withdraw the current plan. Proposed next moves include:
- Hosting fresh examination hearings with enhanced stakeholder input.
- Re-drafting policies on housing targets, cross-border cooperation and environmental safeguards.
- Lobbying central government for clearer guidance on neutrality standards.
Community Impact
Until a compliant plan is adopted, major housing allocations, infrastructure upgrades and ecological projects remain uncertain. Developers may pursue speculative proposals, while residents face delays in affordable housing pipelines and transport improvements.
Conclusion
The rejection marks a critical juncture for Horsham District. Addressing legal, cooperative and environmental shortcomings will be essential to regain momentum. *Successful resubmission* could restore confidence, whereas prolonged stalemate risks development drift and community frustration.
FAQs
Why was the Horsham local plan rejected?
The Planning Inspectorate cited failures in the duty to cooperate with neighbouring authorities and inadequate evidence that proposed measures would achieve water neutrality.
What is water neutrality and SNOWS?
Water neutrality ensures new developments do not increase overall water demand. SNOWS (Sussex North Offsetting Water Strategy) was Horsham’s proposed mechanism to offset additional usage, but inspectors deemed it unproven.
How will the rejection affect housing projects?
Until a revised plan is approved, large housing allocations may face delays or be subject to speculative applications decided on a case-by-case basis.
What happens next for the council?
The council intends to review the inspector’s findings, engage stakeholders, and draft a compliant plan for fresh examination—aiming to balance legal obligations with local priorities.
