Section 106 Agreements
Section 106 planning agreements, often referred to simply as S106 agreements, are legally binding contracts established between local planning authorities and developers. These agreements are designed to address the impacts of new developments and make them acceptable to local communities by securing contributions towards local infrastructure, affordable housing, or other planning obligations.
In essence, Section 106 agreements are an important mechanism for mitigating the adverse effects of development proposals while ensuring that communities benefit from growth and investment within their areas.
The Legislative Framework for Section 106 Agreements
The legislative basis for Section 106 planning agreements can be found in the Town and Country Planning Act 1990. Under Section 106 of the Act, local planning authorities are empowered to enter into agreements or accept unilateral undertakings from landowners or developers in connection with the granting of planning permission.
These obligations can restrict the use of land in a specified way, require specific operations to be carried out on land, or require financial contributions towards local infrastructure projects.
The responsibility for negotiating, drafting, and enforcing such agreements generally falls to the planning authority, which works with developers to ensure that necessary infrastructure and services are provided to mitigate the impact of new development.
The scope and complexity of Section 106 agreements have increased over time, particularly as demand for affordable housing, educational facilities, highway improvements, green spaces, and other community infrastructure has grown.
The Role of Section 106 in the Planning Process
Section 106 planning agreements form an important part of the planning permission process. When considering whether to grant planning permission, local authorities assess the likely impact of a proposed development and determine whether mitigation is necessary.
Where additional measures are required, a Section 106 agreement may be negotiated before planning permission is formally granted.
These agreements are bespoke to individual developments and are negotiated on a case-by-case basis. They may include requirements relating to affordable housing, education or health services, highway improvements, public open space, cultural facilities, or recreational provision.
Where significant local impacts have not been appropriately mitigated, the absence of necessary planning obligations may contribute to a planning application being refused.
Key Components of Section 106 Agreements
Section 106 agreements can contain a wide range of planning obligations depending on the scale, nature, and location of the proposed development. Common obligations include:
-
Affordable Housing: Developers may be required to provide a proportion of new homes as affordable housing, either on-site or through financial contributions towards affordable housing elsewhere.
-
Infrastructure Contributions: Developments can increase demand for schools, roads, health services, and community facilities. Section 106 agreements may therefore require financial contributions towards their expansion or improvement.
-
Open Space and Environmental Improvements: Obligations may include the creation of parks, playgrounds, ecological enhancements, landscaping, or improvements to existing open spaces.
-
Transport and Accessibility: Developers may be required to fund or undertake improvements to public transport services, cycle paths, pedestrian walkways, junctions, or other highway infrastructure.
-
Employment and Skills: Some agreements include commitments relating to local employment, apprenticeships, training, or skills development.
The obligations included in an agreement will depend on the development itself and the priorities identified by the local planning authority through its Local Plan and other relevant policies.
Negotiation and Drafting of Section 106 Agreements
The negotiation and drafting of Section 106 planning agreements can be complex, particularly where a development involves multiple obligations or interested parties.
The process generally begins when a development proposal is considered acceptable in principle but requires specific measures to address its impacts. The developer and planning authority may exchange draft heads of terms setting out the proposed obligations.
These terms are reviewed and negotiated to ensure that the obligations are reasonable, necessary, and directly related to the development.
The National Planning Policy Framework (NPPF) and Community Infrastructure Levy (CIL) Regulations establish the statutory tests for Section 106 obligations. Planning obligations must be:
-
Necessary to make the development acceptable in planning terms.
-
Directly related to the development.
-
Fairly and reasonably related in scale and kind to the development.
Once the terms have been agreed, the Section 106 document is normally prepared as a legally binding deed. It may be signed by the local planning authority, developer, landowner, and other parties with an interest in the land, such as mortgagees.
Enforcement of Section 106 Obligations
Section 106 planning agreements are legally enforceable. If a developer or landowner fails to comply with the obligations contained in an agreement, the local authority may take enforcement action, including seeking an injunction or taking other appropriate legal steps.
Non-compliance can result in delays to the occupation or use of development and may lead to financial consequences or other enforcement measures.
Developers should therefore understand their obligations from the outset and incorporate them into project budgets, programmes, and development strategies. Maintaining clear communication with the local planning authority can also help prevent misunderstandings and potential breaches.
Modification and Discharge of Section 106 Agreements
Circumstances can change after a Section 106 agreement has been entered into, particularly in relation to long-term or phased developments. The legislation allows agreements to be modified or discharged in certain circumstances.
Under Section 106A of the Town and Country Planning Act, an application may be made to the local authority to modify or discharge an agreement, usually after five years from the date it was entered into.
The local authority will consider whether the obligation remains necessary, enforceable, and compliant with the relevant legal tests. Where an application to modify or discharge an obligation is refused, the applicant may have a right of appeal to the Secretary of State.
Regularly reviewing obligations can be particularly important for long-term schemes where market conditions, development proposals, or local circumstances may change.
The Relationship Between Section 106 and the Community Infrastructure Levy
The introduction of the Community Infrastructure Levy (CIL) has changed how developers contribute towards local infrastructure in many parts of England and Wales.
CIL generally operates as a standardised charge based on the amount of new floor space created, whereas Section 106 agreements are primarily used for obligations that are directly related to a particular development.
CIL can contribute towards wider infrastructure requirements identified through local authority charging schedules. Section 106, by contrast, can address site-specific matters such as affordable housing, bespoke highway works, or particular environmental measures.
Where both CIL and Section 106 operate alongside one another, local authorities must ensure that developers are not effectively charged twice for the same infrastructure requirement.
Common Issues and Pitfalls with Section 106 Agreements
The negotiation and implementation of Section 106 agreements can present a number of challenges.
One common issue is delay. Lengthy negotiations can hold up the grant of planning permission, particularly on complex or contentious developments. Disputes can also arise where the parties disagree about the scale, timing, or financial value of proposed obligations.
Viability can be another significant consideration. Developers may argue that the level of contributions requested would make a proposed development financially unviable. Local authorities must therefore balance the need to secure appropriate community benefits with the need to facilitate the delivery of housing and commercial development.
Clear drafting is essential. Ambiguous or incomplete provisions can create uncertainty and increase the risk of future disputes or legal challenges.
Enforceability and Transparency
The circumstances in which Section 106 obligations become enforceable should be clearly defined within the agreement. Payment or delivery obligations may be linked to specific trigger events, such as commencement of development, completion of a particular stage, or occupation of dwellings.
Transparency is also an important part of the planning process. Local authorities maintain records of Section 106 agreements and contributions, allowing communities and other interested parties to monitor the delivery of infrastructure and affordable housing.
Annual Infrastructure Funding Statements can also provide information about funds received and spent through Section 106 and CIL.
The Importance of Section 106 Planning Agreements
Section 106 planning agreements remain an important component of the UK planning system. They help local planning authorities address the impacts of development while securing contributions towards affordable housing, infrastructure, environmental improvements, transport, and other community benefits.
For developers, landowners, and planning professionals, understanding the legal and practical implications of Section 106 obligations is essential. Early engagement with the local planning authority, careful consideration of viability, and precise drafting can help reduce delays and disputes while supporting the successful delivery of development.
As planning policies continue to evolve, Section 106 agreements will remain an important mechanism for managing the relationship between development and local infrastructure and ensuring that the impacts of growth are appropriately addressed.
