Background on Horsham’s Local Plan
*Drafted for 2023-2040*, the Local Plan set ambitious goals for housing delivery, environmental protection and water neutrality. It outlined growth targets while safeguarding sensitive areas like Pulborough Brooks wildlife site. The document was meant to balance prosperity with preservation—no small feat in a district facing population growth and climate pressures.
Why Was the Plan Rejected?
In an interim findings letter dated 4 April 2025, Inspector Luke Fleming listed three fatal flaws:
- Legal compliance failures—procedural gaps breached national planning regulations.
- Duty to cooperate—insufficient collaboration with neighbouring authorities over shared housing targets.
- Water neutrality—the Sussex North Offsetting Water Strategy (SNOWS) lacked credible evidence it could neutralise increased demand.
“Without robust mitigation, the plan is unsound,” Fleming wrote, ending the hearings prematurely and halting further sessions.
Council’s Response
Council leader Martin Boffey described the decision as “deeply disappointing,” yet vowed to push ahead. Horsham has:
- Filed a formal complaint with the Planning Inspectorate.
- Requested intervention by the Minister for Planning and Housing.
Boffey warned that rewriting the document amid ongoing local government reorganisation and staff shortages will be “a monumental task.” Yet he stressed the council’s commitment to meet both housing demand and environmental duties.
What Happens Next?
Developers now face a period of uncertainty. Without an adopted plan, *speculative planning applications* could rise, while the council races to plug legal gaps. Possible outcomes include:
- A revised plan submitted within 12–18 months—if water neutrality evidence can satisfy inspectors.
- Short-term limits on major schemes near sensitive habitats.
- Potential government direction should local progress stall.
Stakeholder Reactions
Reactions swing from anger to relief:
“We need homes, but not at the cost of our rivers and wildlife,” said local resident Sarah King.
- Residents fear rising house prices if targets slip.
- Developers warn the decision “sends mixed signals” about investment certainty.
- Environmental advocates welcome stronger scrutiny of water use.
FAQ
Why did the Planning Inspectorate reject the plan?
Mainly for failing legal compliance, lacking cooperation with neighbouring councils and providing weak evidence for water neutrality.
What is water neutrality and why is it crucial?
Water neutrality ensures that any new development does not increase overall water consumption. This protects local chalk streams and sensitive habitats like Pulborough Brooks.
Will housing projects already approved be delayed?
Projects with full permission can proceed, but new large-scale applications may face additional scrutiny or temporary holds.
How long could a revised plan take?
Council officers estimate 12–18 months, assuming swift evidence gathering and cooperation agreements.
Where can residents track updates?
Updates will be posted on the Horsham District Council planning portal and announced at monthly cabinet meetings.
