Background of the Horsham District Local Plan
The Horsham District Local Plan was designed to guide development from 2023 to 2040, laying out targets for housing, employment space, infrastructure, and environmental conservation. It is effectively the district’s blueprint for growth.
In theory the plan would:
- Meet government-set housing numbers
- Direct investment into roads, schools, health facilities, and green spaces
- Balance economic expansion with environmental safeguards
Details of the Local Plan Rejection
On 4 April 2025 Planning Inspector Luke Fleming stunned councillors by declaring the draft plan legally non-compliant. His interim letter cancelled all remaining hearings.
Three core issues were highlighted:
- Water neutrality: the Sussex North Offsetting Water Strategy (SNOWS) was judged inadequate, risking harm to sites like Pulborough Brooks.
- Housing numbers: the Inspector insisted the district should plan for more homes despite water constraints.
- Duty to collaborate: Horsham allegedly failed to show constructive engagement with neighbouring authorities.
“The evidence does not demonstrate effective cooperation capable of addressing cross-boundary matters.” – Interim Inspector’s findings
Council’s Response and Actions
Describing the verdict as “hugely disappointing”, Horsham District Council immediately lodged a formal complaint with the Planning Inspectorate. Officials argue that national guidelines shifted after their submission and that expert advice underpinned every section of the plan.
- A renewed internal review has begun to address the Inspector’s objections.
- Legal options, including a statutory challenge, are being explored.
- Councillors reaffirmed their commitment to collaboration with adjoining districts.
Implications for Housing Delivery
Without an adopted local plan, developers face uncertainty, and strategic housing sites—particularly around Pulborough Brooks—could stall. Residents worry that ad-hoc applications might fill the vacuum, leading to infrastructure shortfalls.
- Delays could exacerbate local housing shortages.
- Funding for road upgrades and school places may be pushed back.
- Developers might pursue appeals, arguing the council lacks a five-year land supply.
Potential Next Steps
The Inspector advised that Horsham should consider withdrawing the draft entirely and resubmitting a revised version. Possible milestones include:
- Formal withdrawal of the current draft.
- Fresh duty-to-collaborate statements with neighbouring councils.
- New examination hearings once revisions are complete.
- Publication of a timeline to reassure stakeholders.
Broader Context and Local Government Reorganisation
The rejection arrives amid national moves to reorganise local government and potentially repeal the duty to collaborate. Such reforms could redraw planning responsibilities and alter future examinations.
Analysts suggest Horsham must remain agile, aligning its strategy with regional initiatives while anticipating legislative change.
Conclusion
Horsham’s draft local plan may have hit a wall, yet the council’s determination to fight back signals that the story is far from over. Over the coming months the community will watch closely as revised proposals emerge, hoping they unlock sustainable growth, new homes, and much-needed infrastructure.

FAQs
Why was the Horsham Local Plan rejected?
The Planning Inspector ruled it legally non-compliant due to insufficient collaboration with neighbouring councils, unresolved water neutrality concerns, and housing targets deemed too low.
Does rejection mean no new homes can be built?
Not entirely. Individual applications can still proceed, but without an adopted plan the council has less control and risks speculative development.
How long could a revised plan take to adopt?
If the draft is withdrawn and reworked, experts estimate 18–24 months for new consultations, evidence gathering, and a fresh examination.
Could government reforms change the process?
Yes. Proposed legislation to replace the duty to collaborate or reorganise councils might shift how cross-boundary issues are addressed in future plans.
