Section 106 Agreement Planning Permission
Navigating the complexities of the UK planning system requires a sophisticated understanding of how local authorities balance development needs with community infrastructure. A critical mechanism in this process is the legal instrument known as a planning obligation, which is often a prerequisite for securing section 106 agreement planning permission. These agreements are legally binding contracts between developers and local planning authorities (LPAs) designed to mitigate the impact of a new development on the local area.
For professional developers and homeowners alike, these agreements represent a bridge between a conceptual architectural vision and the reality of regulatory approval. Without a properly negotiated agreement, a project that is otherwise policy-compliant may face refusal on the grounds of insufficient infrastructure mitigation. At Approved Planning, we provide the technical precision required to ensure these obligations are fair, transparent, and aligned with your site feasibility objectives.
Key Takeaways
- Legal Framework: Section 106 agreements are established under the Town and Country Planning Act 1990 to make development acceptable in planning terms.
- Mitigation Tool: They are used to offset the impact of development, such as increasing pressure on schools, roads, or healthcare.
- Negotiable Terms: Obligations must meet three legal tests: necessity, direct relationship to the development, and fairness in scale.
- Affordable Housing: This is one of the most common requirements within a Section 106 agreement for residential schemes.
- Land Charges: These agreements are tied to the land, not the owner, meaning they transfer to any subsequent purchasers of the site.
- Viability Assessments: If the costs of an agreement render a project unfeasible, a professional viability assessment can be used to renegotiate terms.
What is a Section 106 Agreement?
A Section 106 agreement is a private legal contract made between a local authority and a developer under Section 106 of the Town and Country Planning Act 1990. Its purpose is to make a development proposal acceptable in planning terms by securing contributions or restrictions that could not be achieved via standard planning conditions.
Core Objectives of Planning Obligations
- Restricting the use of land in a specified way.
- Requiring specific operations or activities to be carried out on the land.
- Requiring the land to be used in a specific way.
- Requiring sums of money to be paid to the local planning authority.
| Feature | Planning Conditions | Section 106 Agreements |
|---|---|---|
| Legal Basis | Section 70/72 of the 1990 Act | Section 106 of the 1990 Act |
| Mechanism | Imposed by the LPA upon approval | Negotiated contract signed by all parties |
| Financials | Cannot be used for financial payments | Primary method for securing financial contributions |
| Scope | Must relate strictly to the site layout/design | Can address off-site infrastructure and social needs |
The Three Legal Tests for Planning Obligations
For a local authority to validly request a section 106 agreement planning permission requirement, the obligation must meet the statutory tests set out in Regulation 122 of the Community Infrastructure Levy (CIL) Regulations 2010. These tests ensure that developers are not unfairly burdened with costs that are unrelated to their specific project.
Firstly, the obligation must be necessary to make the development acceptable in planning terms. This means that without the agreement, the application would likely be refused because it would cause an unacceptable strain on local resources. We meticulously review local plan policies to ensure the council’s demands do not exceed this “necessity” threshold.
Secondly, the requirement must be directly related to the development. A council cannot demand funding for a library in a different part of the borough if the new residents will not reasonably use it. There must be a clear geographical or functional link between the site and the infrastructure being funded.
Finally, the obligation must be fairly and reasonably related in scale and kind to the development. A ten-unit housing scheme should not be expected to fund a multi-million-pound bypass. Our role is to ensure that the financial quantum of the contribution is proportionate to the site feasibility and the projected impact of the occupants.
Common Components of a Section 106 Agreement
While every agreement is bespoke to the specific constraints of a project, several standard categories of obligations frequently appear in UK planning negotiations. Understanding these categories allows developers to forecast costs more accurately during the early stages of a project.
Affordable Housing Provision
For most residential developments exceeding a certain threshold (often 10 units or more, depending on the local plan), the LPA will require a percentage of the homes to be designated as affordable housing. This can be delivered as “on-site” units or via a “commuted sum”—a financial payment used by the council to build affordable homes elsewhere. Negotiating the tenure split between social rent, affordable rent, and shared ownership is a critical aspect of securing viable section 106 agreement planning permission.
Infrastructure and Public Realm
Developments often necessitate upgrades to physical infrastructure. This may include:
– Highways and Transport: Funding for new bus stops, cycle lanes, or junction improvements.
– Education: Contributions toward expanding local primary or secondary schools to accommodate new pupils.
– Healthcare: Grants for local GP surgeries to increase patient capacity.
– Open Space: The creation or maintenance of parks and children’s play areas.
Environmental and Sustainability Mandates
With the increasing focus on national sustainability goals, Section 106 agreements are frequently used to secure Biodiversity Net Gain (BNG) commitments. If a site cannot achieve the required 10% uplift in biodiversity on-site, the agreement will facilitate payments for off-site habitat creation. This is a complex area where our expertise in navigating planning applications ensures that environmental targets are met without compromising project timelines.
The Negotiation Process: Strategy and Timing
The negotiation of a Section 106 agreement typically runs parallel to the assessment of the planning application. It is a collaborative process involving the developer, the LPA’s planning officer, and the legal teams of both parties. Delaying these negotiations until late in the process is a common pitfall that can lead to significant bottlenecks.
Step 1: The Heads of Terms
Early in the application process, the LPA will issue a document known as the “Heads of Terms.” This outlines the main obligations they expect to be included in the legal deed. We review these terms against material considerations and local policy to ensure they are justified before the formal legal drafting begins.
Step 2: Legal Drafting and Review
Once the Heads of Terms are agreed, the council’s solicitors will produce a draft deed. This document includes “trigger points”—specific milestones (such as commencement of development or occupation of the 50th unit) that dictate when payments must be made or works completed. Precision in defining these triggers is vital for maintaining developer cash flow.
Step 3: Execution and Completion
The final document must be signed by all parties with an interest in the land, including mortgagees. Only after the agreement is signed and dated will the formal decision notice for section 106 agreement planning permission be issued. We coordinate these parties to ensure the process remains streamlined, avoiding the administrative delays that often plague large-scale developments.
Viability Assessments and Renegotiation
In some instances, the cumulative cost of Section 106 obligations and the Community Infrastructure Levy (CIL) can make a development financially unviable. In such cases, a professional Financial Viability Assessment (FVA) is required. This technical report demonstrates that the required contributions would prevent the developer from achieving a competitive return.
We work with specialist surveyors to present robust viability evidence to the local authority. If the evidence is accepted, the LPA may agree to reduce the affordable housing requirement or defer infrastructure payments. This ensures that the development can still proceed, delivering much-needed housing while remaining commercially sound.
Key Factors in Viability Negotiations
- Benchmark Land Value (BLV): The value of the land in its existing use plus a premium for the landowner.
- Development Costs: Accurate estimates for construction, professional fees, and financing.
- Gross Development Value (GDV): The projected market value of the completed project.
- Developer Profit: Typically accepted as 15-20% of GDV to account for the risk involved.
Section 106 vs. Community Infrastructure Levy (CIL)
It is important to distinguish between Section 106 and the Community Infrastructure Levy (CIL). While both involve developer contributions, they operate under different mechanisms. CIL is a non-negotiable, fixed charge per square metre of new development, intended to fund general infrastructure across the local authority’s area.
Section 106 is reserved for site-specific impacts that CIL does not cover. For instance, while CIL might fund a new district park, a Section 106 agreement would fund the specific road junction upgrade required to access your site safely. Navigating the interplay between these two systems is essential to avoid “double dipping,” where a developer is charged twice for the same infrastructure item.
| Characteristic | CIL | Section 106 |
|---|---|---|
| Predictability | High (Fixed Tariff) | Variable (Negotiated) |
| Applicability | General Infrastructure | Site-Specific Mitigation |
| Negotiability | Limited (Except for relief) | Highly Negotiable |
| Focus | Raising Revenue | Planning Acceptability |
Managing Risks and Avoiding Common Pitfalls
The legal weight of a Section 106 agreement cannot be overstated. Because these agreements are registered as local land charges, they remain enforceable against the land even if it is sold to a third party. Failure to comply with the terms can lead to injunctions, halting construction, or the council carrying out the work themselves and billing the developer at a premium.
One common mistake is failing to include “mortgagee in possession” clauses. These protect lenders by ensuring they are not liable for the planning obligations if they have to repossess the site, provided they follow specific protocols. Without such clauses, securing development finance can be significantly more difficult.
Another risk involves the wording of trigger points. If a payment is triggered by the “commencement of development,” even minor site clearance or trench digging could legally obligate you to pay hundreds of thousands of pounds immediately. We ensure that definitions for “commencement” are carefully scoped to allow for preliminary works without triggering premature payments.
Advanced Considerations: Section 106 for Small Sites
While Section 106 is traditionally associated with large-scale developments, it can still impact smaller projects, particularly in designated areas like National Parks or Areas of Outstanding Natural Beauty (AONBs). In these sensitive locations, even a single new dwelling might require a contribution toward affordable housing or environmental protection.
For homeowners and small-scale developers, we offer strategic guidance on whether a unilateral undertaking (UU) might be more appropriate. A UU is a simplified version of a Section 106 agreement, offered by the applicant alone without the council being a signatory. This can significantly speed up the process for section 106 agreement planning permission on minor applications, reducing legal fees and administrative wait times.
Modifying and Discharging Agreements
Planning obligations are not necessarily permanent. Under Section 106A of the 1990 Act, an application can be made to the LPA to modify or discharge an obligation if it “no longer serves a useful purpose” or if the proposed modification would allow it to serve its purpose equally well. This usually becomes relevant five years after the agreement was signed, though negotiations can happen sooner by mutual consent.
If you have purchased a site with an existing agreement that is now outdated—perhaps due to changes in permitted development rights or shifts in local market conditions—we can assist in applying for a formal discharge. This process requires a sophisticated understanding of how the original planning balance has shifted over time.
Frequently Asked Questions
Does every planning application require a Section 106 agreement?
No. Most minor applications, such as small domestic extensions or internal changes of use, do not trigger the need for a Section 106. Typically, they are required for developments that create new residential units or significant commercial floorspace where there is a clear impact on local infrastructure. Your consultant will confirm this during a site feasibility assessment.
Can I appeal a Section 106 requirement?
You cannot appeal a Section 106 requirement in the same way you appeal a planning refusal. However, you can refuse to sign the agreement, which will likely lead to a planning refusal, which you can then take to the Planning Inspectorate. Alternatively, you can seek to modify an agreement that has been in place for more than five years through the Section 106A process.
How much does a Section 106 agreement cost?
The cost is twofold. First, there are the actual contributions (e.g., £10,000 for a local park). Second, there are the legal and administrative fees. Developers are usually required to pay the council’s legal costs for drafting the agreement, in addition to their own legal fees. These administrative costs can range from £1,500 to over £10,000 depending on the complexity of the deal.
What happens if I don’t pay the agreed amount?
Section 106 agreements are legally enforceable contracts. If you miss a payment trigger, the council can charge interest, take you to court, or even place an injunction on the site to stop all works. It is critical to monitor your trigger points closely once section 106 agreement planning permission has been implemented.
Is Section 106 the same as affordable housing?
Affordable housing is one of the most common types of obligations found within a Section 106 agreement, but the two are not synonymous. Section 106 is the legal vehicle; affordable housing is the specific requirement being delivered through that vehicle. The agreement can cover many other things, from highway works to employment training schemes.
Can I use Section 106 to secure my own infrastructure?
Yes. Sometimes developers use Section 106 agreements to guarantee that the council will adopt and maintain new roads or sewers built as part of the project. This provides long-term security for both the developer and the future occupants of the site, ensuring that the new infrastructure meets local authority standards.
