Permission With Requirements
What Planning Conditions Do
A planning permission is rarely a simple unrestricted approval. Conditions define what has been permitted, when development may start and which details must be approved or maintained.
Make Development Acceptable
A condition can mitigate an identified planning concern and allow permission to be granted where refusal might otherwise have been necessary.
It should be tailored to the problem rather than used as a broad or unnecessary control.
Control Sequence and Detail
Conditions may require details of materials, access, drainage, ecology, landscaping, contamination, construction management, noise, lighting or phasing.
Some must be approved before commencement, while others apply before occupation, during construction or permanently.
Create Legal and Commercial Consequences
Development carried out in breach of a condition can be unlawful and exposed to enforcement. A condition can also delay commencement, restrict occupation or reduce development flexibility.
Purchasers and lenders therefore treat the decision notice and discharge history as important due-diligence documents.
Planning permission should be valued as a complete package: approved plans, conditions, Section 106 obligations, CIL liability and the technical evidence needed to implement the scheme.
Current Policy Position
Planning Conditions as at 11 August 2026
The established national tests and discharge procedures remain in force, while the current operational NPPF is still the December 2024 framework as amended in February 2025.
National guidance states that conditions should be kept to a minimum and should only be imposed where they satisfy six tests. These principles are important both when conditions are drafted and when a landowner or developer considers whether a permission is capable of practical implementation.
Pre-commencement conditions receive particular attention because they can prevent any material start until the required details are approved. Except for specified circumstances, including the particular treatment of outline permissions, written agreement is generally required before a pre-commencement condition is imposed.
A further draft NPPF was consulted upon between December 2025 and March 2026. The consultation may result in later changes, but draft wording should not be treated as adopted policy until a final framework is published.
Local authorities use model conditions, but every condition must still be read in its own context. Small differences in wording can determine whether approval is required, which works are prohibited, when compliance must occur and whether a breach affects the whole development or a particular phase.
This guide explains the planning and value implications in general terms. The legal effect of an individual condition should be reviewed against the permission, approved plans, legislation and relevant case law.
National Policy Tests
The Six Tests for a Planning Condition
A condition that fails any one of the six tests should not be imposed. The tests help prevent conditions from becoming wider, vaguer or more onerous than the planning issue requires.
Necessary
The condition must be needed to make the development acceptable. It should not repeat controls that are unnecessary or already secured adequately elsewhere.
Relevant to Planning
The condition must address a planning matter rather than a purely private dispute or an issue controlled entirely under unrelated legislation.
Relevant to the Development
The condition must relate to the development authorised by the permission, not an unrelated objective elsewhere.
Enforceable
The authority must be capable of identifying a breach and taking effective action. A condition dependent on an uncertain third party may be problematic.
Precise
The wording should make clear what must be done, by whom and at what stage. Ambiguity creates risk for the authority, developer and future purchaser.
Reasonable
The burden and timing should be proportionate. A condition should not make lawful development practically impossible or impose an excessive requirement.
An applicant’s agreement does not cure a condition that fails the legal and policy tests. Conditions should be justified by the planning merits of the proposal.
Different Timing Points
Common Types of Planning Condition
The trigger wording determines when a condition becomes critical. A robust delivery programme should classify every condition before contracts, financing or construction dates are fixed.
Pre-commencement conditions prevent development from beginning until specified details have been submitted and approved. Common examples include contamination investigation, archaeology, drainage principles, ecological protection and construction management where those matters are fundamental.
Pre-occupation conditions allow work to start but prevent homes or buildings from being occupied until a requirement is satisfied. These may relate to access, drainage, noise mitigation, landscaping, travel measures or completion of particular infrastructure.
Compliance conditions regulate the way the approved development is built or used. They may require construction in accordance with approved plans, control hours, protect retained trees or limit a use to specified activities.
Trigger conditions can apply before a particular phase, dwelling number or percentage of occupation. On a large scheme, the relationship between triggers, infrastructure and sales can have a major effect on cash flow.
Ongoing conditions can restrict future changes, require maintenance or control operation permanently. Their effect may continue long after the original developer has left and should be understood by management companies and future owners.
Reserved matters approvals should not be confused with the discharge of conditions. An outline permission may reserve access, appearance, landscaping, layout and scale for later approval through one or more reserved matters applications. Conditions attached to the outline permission remain separate requirements and must still be tracked. Conditions imposed when reserved matters are approved can only relate directly to those reserved matters.
Phased and hybrid permissions require particular care. A condition may apply to the whole site, before the first commencement anywhere, before each phase begins or before occupation within a defined phase. Approval for one phase does not necessarily discharge the same requirement for later phases, and premature work in one part of the site can breach a site-wide trigger. The condition schedule should record the exact spatial scope, trigger and whether full or partial discharge has been granted.
Examples to Identify Early
Approved Plans
Which drawings and documents define the permission and whether later design flexibility remains.
Site Investigation
Contamination, mining, archaeology, ground gas and remediation approvals.
Access and Highways
Junction details, visibility, construction access, travel plans and off-site works.
Drainage
Surface water, foul drainage, SuDS design, maintenance and adoption.
Ecology and Landscape
Protected species, biodiversity, tree protection, planting and management.
Occupation and Phasing
Infrastructure or mitigation that must be delivered before homes can be occupied.
A permission with numerous conditions is not automatically poor. The key questions are whether the conditions are proportionate, clear, technically achievable and aligned with the intended programme.
Before Construction
How Conditions Are Discharged
Conditions requiring further approval normally need a formal written submission supported by sufficient technical information.
Create a Condition Schedule
List every condition, its trigger, responsible consultant, required evidence, fee, target submission date and dependency on other approvals.
Prepare Coordinated Evidence
Ensure drainage, highways, ecology, landscape, engineering and design submissions are consistent with each other and with the approved plans.
Submit and Monitor
Make the formal discharge application, pay the required fee, retain proof of validation and monitor consultation responses and the statutory decision period.
Confirm Compliance
Obtain the written decision, check whether the condition is discharged fully or in part, and retain an auditable record before the relevant works or occupation occur.
A consultant’s report does not discharge a condition by itself. Where the wording requires approval, written approval from the local planning authority is normally needed before the stated trigger.
Timescales and Procedure
Delay in Discharging Conditions Can Affect Delivery
National guidance sets decision periods, but incomplete information, consultation and technical revisions can still delay a site.
The local planning authority should determine a written request to discharge a condition within eight weeks, unless a longer period is agreed. For certain approvals connected with Environmental Impact Assessment development, a longer sixteen-week period applies.
If no decision is made within twelve weeks, the authority must generally return the discharge fee, although that does not itself mean that the condition has been approved. The developer may have an appeal right and, for eligible conditions, may consider the deemed-discharge procedure.
Deemed discharge is not automatic. It must be activated using the prescribed procedure and does not apply to all conditions. A notice can generally only be served after at least six weeks from receipt of the discharge application, unless a shorter period is agreed, and the condition must not fall within an excluded category.
In practice, the best way to protect the programme is to identify requirements early, submit complete information and engage with the relevant consultees. Waiting until the planned start date to address archaeology, drainage, ecology or highways can make delay unavoidable.
The programme should also allow for revisions. A technical consultee may ask for modelling, calculations, drawings or mitigation that were not anticipated when the application was granted. That work can affect layout, cost and the date on which a lawful start is possible.
The eight-week period is a decision target, not a substitute for forward planning. Critical pre-commencement conditions should normally be prepared well before the intended start date.
Effect on Value
How Conditions Can Reduce or Delay Development Land Value
Conditions influence value through cost, capacity, timing, certainty and the purchaser’s perception of risk.
Programme Delay
A pre-commencement condition can postpone the lawful start of development. A pre-occupation condition can postpone sales or rental income.
Delay increases finance, holding and professional costs and may expose the scheme to changing market conditions.
Additional Cost
Surveys, design work, monitoring, remediation, off-site works and long-term management may be required before a condition can be discharged.
The cost should be included in the development appraisal rather than treated as an incidental post-permission expense.
Reduced Capacity
Drainage, ecology, landscape, heritage or access requirements may reduce the net developable area or number of homes that can be delivered.
A permission’s headline unit number may not reflect later detail required by the conditions.
Implementation Risk
Unclear, conflicting or technically difficult conditions can reduce buyer confidence and increase contingency.
Purchasers may discount the land until the discharge route and likely cost are understood.
Improved Certainty
A well-drafted permission with proportionate conditions can add value by establishing a clear route to implementation.
Discharging key conditions before sale may reduce uncertainty and widen purchaser interest.
Cash-Flow Effect
Trigger points can require infrastructure before occupation or before a particular phase proceeds.
The developer may need to fund substantial works before receiving sales income, affecting residual land value.
Two permissions for the same number of homes can have different values because one carries clearer, cheaper and more flexible conditions than the other.
Changing Conditions
Can a Condition Be Removed or Varied?
An applicant should not simply ignore an undesirable condition. Formal routes may be available, but each has procedural and commercial consequences.
Section 73 of the Town and Country Planning Act 1990 can be used to apply for the removal or variation of a condition. The authority considers the condition or conditions in question rather than treating the application as an entirely new proposal, but the resulting decision creates a new permission.
The original permission remains in existence. A Section 73 decision should restate the conditions that apply to the new permission, and the relationship between the original and varied permissions must be managed carefully.
Section 73 cannot be used to change the description of development or extend the statutory time limit for commencing the permission. The proposed amendment must be capable of being achieved through removal or variation of a relevant condition; otherwise a fresh planning application may be required, while a non-material amendment route may be suitable for genuinely minor changes.
A condition can also be challenged by appeal following the grant of permission, subject to the applicable time limit. An appeal against conditions can reopen the whole planning decision, creating a risk that permission is not preserved in the form expected.
Where the permission is linked to a Section 106 agreement or CIL liability, a condition variation may also require a deed of variation, revised liability notice or fresh commercial review. The planning, legal and valuation consequences should be considered together.
Questions Before Applying
What Is the Planning Objective?
Identify why the condition was imposed and whether the objective can still be achieved differently.
Is the Change Material?
Consider whether Section 73 is legally capable of delivering the amendment sought.
Will Other Conditions Change?
Review the complete condition set and the need for updated plans or technical evidence.
Does Section 106 Need Variation?
Check whether the legal agreement refers to the original permission, plans, unit numbers or triggers.
Does CIL Change?
A Section 73 permission can alter CIL treatment and may require a revised liability calculation.
Will Value Improve?
Compare the cost, delay and appeal risk with the commercial benefit of the proposed variation.
A variation that improves design flexibility may add value, but an unnecessary application can create delay, new conditions and uncertainty. The route should be selected strategically.
Compliance and Enforcement
What Happens if a Condition Is Breached?
A breach can affect lawfulness, finance, saleability and the authority’s willingness to permit occupation or later phases.
Where a pre-commencement condition has not been complied with, development may be unlawful and vulnerable to enforcement. The precise consequence depends on the wording, the nature of the condition, the works undertaken and the relevant legal principles.
A local planning authority can investigate, request information, serve notices and take other enforcement action. A breach of condition notice can require compliance within a specified period, and failure to comply can create further legal consequences.
A retrospective application or Section 73A route may be considered in some circumstances, but there is no guarantee that the authority will approve the position after the event. Remedial work may be expensive or impossible once development has progressed.
Lenders, purchasers and solicitors will normally ask for the decision notices and discharge approvals. Missing documents, inconsistent construction or uncertainty about implementation can delay a transaction and lead to retention, indemnity requests or price reduction.
The safest approach is to maintain a live condition tracker, obtain written decisions and keep a complete record of approved drawings, reports, samples, correspondence and implementation evidence for each phase.
Do not rely solely on informal officer correspondence where the condition requires formal approval. The planning register should contain a clear and complete compliance history.
Commercial Due Diligence
What a Buyer or Landowner Should Check
The permission should be reviewed as an implementable asset rather than a single decision notice.
| Document or Issue | Why It Matters | Value or Delivery Risk |
|---|---|---|
| Decision notice and approved plans | Defines the development and the complete condition set. | Unclear plans or conflicting documents can reduce design certainty and capacity. |
| Condition-discharge decisions | Shows which approvals have been obtained and whether they are full, partial or phase-specific. | Missing approvals can prevent commencement or occupation and expose the development to enforcement. |
| Technical submissions | Explains the engineering, drainage, ecology, landscape and other commitments made to discharge conditions. | Approved detail may be more expensive or restrictive than the original application drawings suggested. |
| Section 106 and highways agreements | Contains separate obligations and triggers that may interact with conditions. | Infrastructure or occupation may be blocked until legal obligations are satisfied. |
| CIL notices and payment position | Confirms liability, relief, commencement procedure and outstanding sums. | Unresolved liability can pass with the land or affect completion and finance. |
| Implementation evidence | Shows whether permission was commenced lawfully and within time. | An expired or unlawfully implemented permission may have materially less value. |
A clear planning compliance pack can reduce purchaser uncertainty and support competitive marketing. It should be assembled before the sale process, not after questions are raised.
Landowner Strategy
Managing Conditions Through Promotion and Sale
Condition risk should be controlled from the application stage through to the final land sale.
Review Draft Conditions
Identify unnecessary, imprecise or commercially damaging wording before the decision is issued and propose proportionate alternatives.
Align Permission and Agreement
Ensure the conditions, Section 106, CIL assumptions and private land agreement operate consistently.
Discharge Critical Matters
Prioritise conditions that affect commencement, capacity, cost or buyer confidence and maintain a complete evidence record.
Market the Real Permission
Provide purchasers with the approved plans, conditions, discharge status, technical information and an honest assessment of remaining risk.
The objective is not always to discharge every condition before sale. It is to remove avoidable uncertainty and ensure purchasers can price the remaining work accurately.

Click hereFrequently Asked Questions About Planning Conditions and Land Value
What is a planning condition?
A planning condition is a legally enforceable requirement attached to a planning permission. It can control the approved development, require further details, regulate timing or secure mitigation.
Conditions form part of the permission and should be read with the approved plans and any legal agreement.
What are the six tests for planning conditions?
A condition should be necessary, relevant to planning, relevant to the development permitted, enforceable, precise and reasonable in all other respects.
A condition that fails one of those tests should not be imposed even where an applicant is prepared to accept it.
What is a pre-commencement condition?
It is a condition that prevents development from beginning until specified information or action has been approved or completed. Typical subjects include archaeology, contamination, drainage, ecological protection and construction management where fundamental.
Starting work first can create serious lawfulness and enforcement risk.
Does an applicant have to agree a pre-commencement condition?
Written agreement is generally required before a pre-commencement condition is imposed, subject to statutory exceptions and the particular treatment of outline planning permission. The authority can use a prescribed notice process where agreement has not been obtained.
The exact procedural position should be checked before relying on the absence of agreement.
How do I discharge a planning condition?
Submit a formal written application to the local planning authority with the information required by the condition and the applicable fee. The authority should issue a written decision confirming whether the condition is approved fully, partly or not at all.
A consultant report alone is not sufficient where formal approval is required.
How long does condition discharge take?
The standard decision period is generally eight weeks, or sixteen weeks for specified approvals connected with EIA development, unless a longer period is agreed. Technical consultation and requests for further information can still affect the practical programme.
Applications should be prepared well before the intended trigger date.
What is deemed discharge?
For eligible conditions, deemed discharge can treat approval as given where the prescribed notice procedure is followed and the authority does not decide the application by the relevant date. It is not automatic and several categories are excluded.
Specialist advice should be obtained before relying on it.
Can a condition be removed or changed?
A Section 73 application can be used to seek removal or variation of a condition where the proposed change is within the scope of that procedure. A non-material amendment or fresh application may be more appropriate in other cases.
Section 106 and CIL consequences should also be reviewed.
Does Section 73 cancel the original permission?
No. The original permission continues to exist, while a successful Section 73 application creates a new permission with its own complete set of conditions. The developer must be clear which permission is being implemented.
Decision notices and legal agreements should be coordinated.
Can planning conditions reduce land value?
Yes. Conditions can require costly work, reduce capacity, delay commencement or occupation and create uncertainty that purchasers price as risk. Conversely, proportionate and clearly discharged conditions can improve certainty and marketability.
The effect depends on the actual wording and technical route to compliance.
Can development start while conditions are outstanding?
That depends on the trigger. Conditions that apply before occupation or later phases may remain outstanding while initial work proceeds, but a pre-commencement condition can prevent a lawful start.
Every condition should be classified before works begin.
What happens if a condition is breached?
The authority may investigate and take enforcement action. The breach can also affect sale, lending, insurance and whether the development is regarded as lawfully implemented.
Retrospective approval is not guaranteed and may not repair every consequence.
Should conditions be reviewed before buying development land?
Yes. A buyer should review the permission, approved plans, condition schedule, discharge decisions, technical submissions, Section 106 agreement, CIL position and evidence of lawful implementation.
An unresolved condition can change both the cost and timing assumptions underlying the price.
Does a permission with many conditions have less value?
Not necessarily. Major development often requires a substantial condition set. Value depends on whether the conditions are clear, proportionate, achievable and coordinated with the programme.
A shorter but unusually restrictive condition can be more damaging than several routine conditions.
What information should I send for an initial review?
Provide the site location and, where available, the planning reference, decision notice, approved plans and any condition-discharge decisions. A postcode or map pin is enough where no application has yet been made.
The initial review can identify the development route and the matters likely to require technical or legal input.
