Section 106 Agreements.
π 1) Introduction to Section 106 Agreements
Section 106 of the Town and Country Planning Act 1990 (UK) allows local planning authorities to enter into planning obligations with developers. These obligations are:
- Legally binding agreements between the local authority and the developer.
- Attached to planning permissions to mitigate the impact of development on local infrastructure and communities.
- Commonly referred to as S106 agreements or planning obligations.
Purpose:
- Secure contributions to infrastructure (roads, schools, hospitals, parks).
- Ensure affordable housing provision.
- Mitigate environmental or social impacts of development.
- Ensure compliance with planning policies when granting permission.
π 2) Legal Framework
- Town and Country Planning Act 1990, Section 106 β empowers local authorities to attach obligations to planning permissions.
- Community Infrastructure Levy (CIL) Regulations 2010 β complements S106 agreements, especially for financial contributions.
- Policy Guidance β National Planning Policy Framework (NPPF) and Local Development Plans guide how S106 obligations are negotiated.
Types of Obligations under S106:
- Financial contributions: e.g., funding for schools, roads, affordable housing.
- Physical works: e.g., constructing footpaths, highways.
- Restrictions: e.g., limiting use of property or controlling phasing of development.
- Maintenance obligations: ensuring long-term upkeep of communal areas.
π 3) Key Principles in S106 Agreements
- Nexus/Relationship Test: Obligations must be directly related to the development.
- Reasonableness: Contributions must be fair and reasonable in scale and type.
- Planning Purpose: Obligations must serve planning objectives and not be used for unrelated goals.
- Enforceability: Must be legally binding, properly executed, and registered on the land title.
π 4) Key Case Laws on Section 106 Agreements
1οΈβ£ Newbury District Council v Secretary of State for the Environment [1981] AC 578
- Principle: Conditions and obligations must serve planning purposes.
- Significance: Foundation for assessing validity of S106 agreements; obligations unrelated to planning are unenforceable.
2οΈβ£ Tesco Stores Ltd v Secretary of State for the Environment [1995] 1 WLR 759
- Principle: Conditions attached to planning permission must be reasonable and necessary.
- Significance: Directly influences S106 agreements; financial obligations must relate proportionately to the development.
3οΈβ£ R v Westminster City Council ex parte Monahan [1990] 1 WLR 1196
- Principle: Planning authorities must exercise discretion lawfully when imposing obligations.
- Significance: Ensures S106 agreements are not arbitrary and reflect proper planning objectives.
4οΈβ£ Gallagher v Solihull Metropolitan Borough Council [2007] EWCA Civ 1205
- Principle: S106 agreements must clearly define scope and enforceability.
- Significance: Court upheld that ambiguity in obligations can render them unenforceable.
5οΈβ£ Tesco Stores Ltd v Dundee City Council [2012] UKSC 13
- Principle: Clarified that obligations must pass the βthree testsβ: necessary, directly related, and fairly and reasonably related in scale.
- Significance: Modern application of Section 106 tests under UK law.
6οΈβ£ Crest Nicholson Residential (South) Ltd v Secretary of State for Communities and Local Government [2008] EWCA Civ 1228
- Principle: Local authorities cannot impose unlawful conditions or financial demands beyond what is necessary to make development acceptable.
- Significance: Reinforces limits on S106 obligations and prevents overreach.
7οΈβ£ Burton v Secretary of State for Communities and Local Government [2011] EWHC 3666 (Admin)
- Principle: S106 agreements are legally enforceable obligations; non-compliance allows authorities to take legal action.
- Significance: Confirms the binding nature and remedies for breach.
π 5) Common Issues in S106 Agreements
- Viability Challenges: Developers sometimes argue obligations make projects financially unviable.
- Ambiguity in Drafting: Poorly drafted agreements may fail enforceability tests.
- Timing of Contributions: When payments or works are due is often litigated.
- Compliance Monitoring: Local authorities must ensure obligations are met over time.
π 6) Practical Implications for Developers and Authorities
- Developers must budget for obligations upfront to ensure planning permission compliance.
- Authorities must justify all S106 contributions with clear planning purpose.
- Legal advice is crucial to draft enforceable, precise obligations.
- Coordination with CIL requirements ensures no double charging occurs.
