Securing planning permission can, depending on the nature of the proposal, require a significant volume of plans, reports and other supporting information. However, obtaining permission is not always the end of the planning process.
Receiving planning permission is an important milestone, but it does not necessarily mean that work can begin immediately. Further information may still require to be submitted to and approved by the Planning Authority before development commences or reaches a particular stage.
For this reason, planning permission is frequently granted subject to conditions controlling how, when or for what purpose a development may proceed. Conditions may require additional details to be approved, regulate particular stages of construction or occupation and govern the continuing use or operation of the development once it is complete.
Planning conditions are not secondary notes or optional recommendations. They form part of the planning permission, are legally binding and must be read alongside the approved plans and any other documents incorporated into the decision.
Key Takeaway
Planning conditions are a core and legally binding part of planning permission. They should be reviewed before development begins, incorporated into the project programme and made available to everyone involved in delivering the development. Failure to comply with a condition or an approved plan can result in delays, enforcement action or, in some circumstances, development being regarded as unauthorised.
Planning Permission Is More Than the Decision Notice
A planning permission will normally comprise more than the written decision notice in isolation. The approved development is defined by the decision notice, the approved plans and any specifications, reports or other documents expressly incorporated into the permission.
Development must therefore comply not only with the wording of each condition, but also with the approved drawings, specifications and supporting information.
Applicants should not ignore planning conditions or treat them as an afterthought once permission has been granted. They are a core part of the permission and can materially affect:
- When construction may begin
- The sequence in which work must be undertaken
- The materials and finishes that may be used
- The position, dimensions and appearance of development
- Drainage, access and landscaping arrangements
- Environmental protection and mitigation measures
- When a building may be occupied or a use commenced
- How the completed development may operate in the longer term
A development may benefit from planning permission but still be unauthorised if it is not carried out in accordance with the approved plans or the requirements of its conditions.
Making Sure Everyone Understands the Permission
The applicant, developer, client or homeowner should not assume that architects, engineers, project managers, builders, subcontractors or future occupiers are aware of the detailed requirements of the planning permission.
Everyone involved in delivering the development should be provided with the relevant approved documents, including:
- The planning permission decision notice
- Every approved drawing
- Approved specifications and supporting reports
- Subsequent approvals relating to planning conditions
- Any approved non-material variations
- Any later permission varying or removing a condition
This is particularly important for contractors working on site. A contractor may be following building standards drawings, engineering information or verbal instructions which do not fully reflect the approved planning plans.
Differences which appear minor during construction can still result in a breach of planning control. Examples may include changes to window positions, finished floor levels, external materials, parking arrangements, boundary treatments or the position of ancillary structures.
The person responsible for the development should therefore ensure that the correct approved documents are clearly issued to all parties and that work on site is periodically checked against them.
Responsibility should not be left to assumptions about what another party may have seen, been told or understood. Where revised drawings or details are approved, outdated versions should also be withdrawn from use to reduce the risk of mistakes.
What Is a Planning Condition?
A planning condition is a legally binding requirement or restriction imposed when planning permission is granted.
Conditions can allow a Planning Authority to approve development which might otherwise be unacceptable or premature. Rather than refusing an application outright, the Planning Authority may use conditions to secure necessary details, safeguards or controls.
Conditions may regulate matters such as:
- External materials and finishes
- Landscaping and boundary treatments
- Tree protection
- Drainage and flood-risk measures
- Access, visibility splays and parking
- Archaeological investigation
- Ecological protection and mitigation
- Contaminated land
- Construction working practices
- Noise and lighting
- Opening or operating hours
- The use of land or buildings
- Occupancy restrictions
- The removal of permitted development rights
Some conditions require a particular action to be completed only once. Others continue to regulate the development throughout its lifetime.
Why Are Planning Conditions Applied?
Planning conditions are principally used to make development acceptable in planning terms and to ensure that it is carried out in a manner consistent with the development plan and other material planning considerations.
They may be necessary to protect:
- Residential amenity
- Public road safety
- Landscape and visual amenity
- Biodiversity
- The historic environment
- Watercourses and drainage systems
- Public access
- Infrastructure capacity
- The character or function of an area
A condition should address a genuine planning requirement. It should not be imposed merely because it might be useful or because the Planning Authority wishes to retain general control over the development.
Scottish Government Planning Circular 4/1998 provides the principal national guidance on the use of conditions in planning permissions.
When Might a Section 75 Planning Obligation Be Used Instead?
A planning condition is not always the appropriate mechanism for securing a planning requirement.
Where a particular matter requires to bind parties who are not directly subject to the planning permission, affects land outwith the application site or relates to activities which fall outwith the scope of the planning permission, a Section 75 Planning Obligation may be used instead.
A Planning Authority may also seek a planning obligation where the requirement needs to bind future owners or successors in title or cannot be adequately secured through a condition attached to the planning permission.
Section 75 Planning Obligations are entered into under Section 75 of the Town and Country Planning (Scotland) Act 1997 (as amended). They were formerly commonly known as Section 75 Agreements, although the statutory terminology is now planning obligations.
They may be used to secure matters such as:
- Developer contributions towards infrastructure or services
- The provision or retention of affordable housing
- Phased financial contributions
- Restrictions affecting other land
- Long-term management and maintenance arrangements
- Obligations which require to bind successors in title
- Measures involving parties other than the applicant or developer
Unlike a planning condition, a Section 75 Planning Obligation is not simply attached to the planning permission decision notice. It is contained within a separate formal legal instrument.
A planning obligation may be registered in the Land Register of Scotland or recorded in the General Register of Sasines. Once registered or recorded, it can bind future owners and successors in title as well as the original parties.
Section 75 Planning Obligations can therefore have significant and long-lasting implications for the land concerned. Their requirements may also be enforced through the courts.
A planning obligation should not be used simply because a Planning Authority would prefer a formal legal agreement. It should serve a genuine planning purpose, relate to the proposed development and be proportionate in scale and kind.
Where a matter can properly and effectively be addressed through a planning condition, a condition will generally be preferable to entering into a planning obligation.
Planning.scot will examine Section 75 Planning Obligations in greater detail, including how they are negotiated, registered, modified, discharged and enforced, in a separate article.
The Six Tests for Planning Conditions
Scottish Government Planning Circular 4/1998 sets out six tests which planning conditions should satisfy.
A condition should be:
- Necessary
- Relevant to planning
- Relevant to the development being permitted
- Enforceable
- Precise
- Reasonable in all other respects
These tests are important because planning conditions can restrict the use of land and impose significant obligations on applicants, landowners and future occupiers.
A condition which is vague, unnecessary, unrelated to the proposal, unreasonable or impossible to enforce may be open to challenge.
The Planning Authority should also provide a clear reason explaining why each condition has been imposed.
Different Types of Planning Condition
Planning conditions can operate at different stages of a project.
Pre-commencement conditions
A pre-commencement condition requires specified action to be taken or details to be approved before development begins.
Examples may include:
- Approval of a Construction Environmental Management Plan
- Archaeological investigation
- Installation of tree protection fencing
- Contaminated land investigation
- Approval of drainage details
- Ecological mitigation
- Construction traffic arrangements
- Approval of site levels
- Pegging out and approval of the position of a building
These conditions must be identified before any material operation is undertaken on the land.
Starting work before a pre-commencement condition has been satisfied can place the development in breach of planning control. It may also create uncertainty over whether the permission has been lawfully commenced, particularly where the condition goes to the heart of the permission.
For example, a condition may require the footprint of a proposed house to be pegged out on site and its position approved by the Planning Authority before development begins. Failure to comply could result in the house being constructed in the wrong position.
Depending on the wording and significance of the condition, development undertaken without the required approval may not constitute a lawful commencement of the planning permission. Should the three-year commencement period subsequently expire, the house could then be considered unauthorised, notwithstanding the existence of the original permission.
Applicants should therefore review all conditions carefully before arranging a site start, ground clearance, excavation, access works or any other operation which may amount to commencement of development.
Conditions applying before a particular stage
Some conditions allow development to begin but require compliance before a later stage is reached.
For example, a condition might require:
- External materials to be approved before they are used
- Landscaping to be completed before occupation
- Access works to be completed before a building is brought into use
- Drainage infrastructure to be operational before occupation
- Noise mitigation to be installed before a commercial use commences
- Parking and turning areas to be completed before occupation
These conditions should be incorporated into the construction programme so that the relevant stage is not reached before the necessary approval has been obtained or work completed.
Continuing or operational conditions
Other conditions regulate the completed development on an ongoing basis.
They may control:
- Hours of operation
- Delivery times
- Noise levels
- External lighting
- Occupancy
- Storage arrangements
- The type of activities permitted
- Retention of landscaping or parking
- Use of holiday accommodation
- Use of an ancillary building
These conditions may continue indefinitely and can bind future owners or occupiers.
What Does It Mean to Purify a Planning Condition?
In Scotland, the term purify is commonly used to describe satisfying the requirements of a planning condition.
Depending on its wording, the condition may require the Planning Authority’s written:
- Approval
- Consent
- Agreement
- Confirmation of compliance
A submission seeking to purify a condition should respond directly to its wording and include all necessary plans, reports, specifications or other evidence.
For example, where a condition requires approval of external materials, it may not be sufficient to provide a general description such as “grey roof tiles”. The Planning Authority may require details of the manufacturer, product, colour, profile and finish together with photographs, technical literature or physical samples.
Applicants should also distinguish between:
- Submitting information to the Planning Authority
- Receiving written approval of that information
- Completing physical work required by the condition
- Obtaining written confirmation that the completed work complies
Sending information to the Planning Authority does not, in and of itself, mean that the condition has been purified.
Where written approval is required, the applicant should normally wait until that approval has been issued before proceeding to the stage controlled by the condition.
Similarly, approval of submitted details does not necessarily confirm that physical works have subsequently been completed in accordance with those details. A separate request for written confirmation of compliance may sometimes be appropriate.
Is There a Fee for Purifying Planning Conditions?
A Planning Authority may introduce a fee for considering a request for written confirmation that a planning condition has been complied with.
Under the Scottish planning fee arrangements applying from 1 April 2026, the fee is £124 for each request, where the Planning Authority has chosen to introduce the charge.
A single request may seek written confirmation regarding more than one condition and would incur one fee of £124.
This charge is not automatically applied by every Planning Authority. The relevant Planning Authority’s published schedule of charges should therefore be checked before a request is submitted.
The charge relates to a request for written confirmation of compliance. It does not include an Application for Approval of Matters Specified in Conditions relating to Planning Permission in Principle, which is a separate statutory application subject to its own planning application fee.
Planning Permission in Principle and Approval of Matters Specified in Conditions
Planning Permission in Principle establishes whether a development is acceptable in principle without necessarily approving all aspects of its detailed design, siting or layout.
The permission will identify matters which require subsequent approval before development can proceed. These may include:
- Siting
- Design
- Layout
- Access
- External appearance
- Landscaping
- Drainage
The applicant must submit an Application for Approval of Matters Specified in Conditions, commonly referred to as an AMSC application.
An AMSC application is a formal statutory planning application. It should not be confused with a routine submission seeking approval or confirmation under a condition attached to full planning permission.
Planning Permission in Principle and any subsequent AMSC approval must be read together. Development must comply with the plans, documents and conditions forming part of both decisions.
Can a Planning Condition Be Varied or Removed?
An applicant may apply under Section 42 of the Town and Country Planning (Scotland) Act 1997 (as amended) for planning permission to develop land without complying with one or more conditions attached to an earlier permission.
A Section 42 application may seek to:
- Remove a condition
- Amend its wording
- Relax a restriction
- Substitute alternative requirements
- Change opening or operating hours
- Revise an occupancy restriction
- Amend an approved phasing arrangement
A Section 42 application does not simply amend the wording of the original decision notice. If approved, it results in a new planning permission which should restate the conditions that continue to apply.
The Planning Authority’s consideration should focus on the condition or conditions which the applicant seeks to change and the consequences of allowing development to proceed without complying with them in their original form.
The original permission continues to exist irrespective of the outcome of the Section 42 application. However, the original condition remains in force and should continue to be observed unless and until a new permission is granted.
Can Planning Conditions Be Appealed or Reviewed?
An applicant may challenge conditions imposed when planning permission is granted.
The correct procedure depends on the category of development and whether the application was decided by an appointed officer or by the Planning Authority’s planning committee.
The decision notice should explain whether the applicant has a right to seek review by the Local Review Body or to appeal to Scottish Ministers.
Local development decided by an appointed officer
Where an application for local development was determined by an appointed officer under the Planning Authority’s Scheme of Delegation, the applicant may normally seek a review by the Planning Authority’s Local Review Body.
The review may challenge one or more of the conditions imposed as part of the decision.
Local development decided by committee
Where an application for local development was determined by a planning committee rather than an appointed officer, the applicant’s route is generally an appeal to Scottish Ministers.
The appeal will normally be administered by the Scottish Government’s Planning and Environmental Appeals Division and determined by a reporter appointed by Scottish Ministers.
Major and national development
Applications for major and national developments do not fall within the Local Review Body system.
The applicant’s route of challenge is generally an appeal to Scottish Ministers, whether the dispute concerns refusal of planning permission, conditions attached to a permission or a failure to determine the application within the applicable period.
Decisions relating to the approval or purification of conditions
A refusal to approve details required by a condition, or failure to determine an application or submission within the applicable period, may also carry a right of review or appeal.
Where the matter relates to a local development and was determined by an appointed officer under the Scheme of Delegation, the route will normally be the Local Review Body.
For major or national development, or local development determined by committee, the route will generally be an appeal to Scottish Ministers.
Requests for review and appeals must normally be submitted within three months of the decision or expiry of the relevant determination period.
Statutory fees now apply to planning appeals and local reviews in Scotland, subject to the relevant exemptions.
Should a Condition Be Challenged Immediately or Varied Later?
An applicant who objects to a condition imposed on a new planning permission may have a choice between:
- Challenging it through a local review or appeal
- Accepting the permission and later submitting a Section 42 application
These procedures are not identical.
A review or appeal directly challenges the original decision and the conditions imposed as part of it.
A Section 42 application asks the Planning Authority to grant a new planning permission without compliance with the specified condition in its existing form.
The most appropriate route will depend on matters including:
- The nature and effect of the condition
- Whether the remainder of the permission is acceptable
- The urgency of progressing the development
- The prospects of agreeing an alternative condition
- The applicable application, review or appeal fee
- The possible implications of issuing a new planning permission
- The risk of reopening related planning considerations
Professional planning advice may be worthwhile before selecting a route.
What Happens if a Planning Condition Is Not Complied With?
Failure to comply with a planning condition is a breach of planning control.
The Planning Authority has discretion over whether formal enforcement action is expedient. It should consider the seriousness of the breach, its planning effects and whether the matter can be resolved through proportionate informal action.
The Planning Authority may initially:
- Contact the owner, developer or occupier
- Request information or evidence
- Ask for unauthorised work or activities to stop
- Seek corrective works
- Invite an application to regularise the position
- Suggest a Section 42 application where appropriate
- Seek retrospective submission of details where this remains capable of resolving the breach
However, the Planning Authority is not required to pursue informal resolution before taking formal action.
Formal measures may include:
- A Planning Contravention Notice
- A Breach of Condition Notice
- An Enforcement Notice
- A Temporary Stop Notice
- A Stop Notice
- Direct action
- Prosecution for failure to comply with a statutory notice
The appropriate response will depend on the wording of the condition, the circumstances of the breach and the nature of any planning harm being caused.
What Is a Breach of Condition Notice?
A Breach of Condition Notice may be served where development has not complied with a condition attached to planning permission.
The notice identifies the condition which has been breached and specifies the steps required to secure compliance or the activities which must cease. The period allowed for compliance must be at least 28 days from the date on which the notice is served, although the Planning Authority may allow a longer period or subsequently extend it.
There is no statutory right of appeal against a Breach of Condition Notice.
A recipient may make representations to the Planning Authority or, in appropriate circumstances, seek legal advice regarding the validity of the notice. However, making representations does not suspend or extend the stated period for compliance.
Failure to comply with a valid Breach of Condition Notice after the compliance period has expired is an offence.
As an alternative to prosecution, the Planning Authority may issue a fixed penalty notice. The fixed penalty for failing to comply with a Breach of Condition Notice is currently £300, reduced to £225 where it is paid within the first 15 days. The full amount must otherwise be paid within 30 days.
There is no right of appeal against the fixed penalty notice, although representations may be made to the Planning Authority where the recipient believes that the breach has been corrected or that the notice should not have been issued.
Payment of the fixed penalty removes liability to prosecution for the particular breach to which it relates. However, it does not remove the continuing requirement to comply with the original Breach of Condition Notice. Paying the penalty should therefore not be viewed as a means of avoiding compliance.
The Planning Authority is not required to offer a fixed penalty notice. It may instead decide to pursue prosecution or take another proportionate course of action.
It is therefore important to respond promptly if the Planning Authority raises concerns about compliance with a planning condition.
Can Development Continue While a Condition Is Outstanding?
This depends entirely on the wording of the condition.
A condition may prevent:
- Any development from commencing
- A particular phase from beginning
- Specified materials from being used
- A building from being occupied
- A business or other use from commencing
- Development progressing beyond a defined stage
Applicants should not assume that work can continue merely because a condition submission has been lodged.
Unless the condition expressly allows otherwise, the relevant written approval should normally be obtained before the controlled stage is reached.
Proceeding at risk may lead to abortive work, redesign costs, construction delays, difficulties selling or financing the property or planning enforcement action.
Managing Conditions as Part of the Development Programme
Planning conditions should be reviewed immediately after permission is granted and incorporated into the overall development programme.
A conditions schedule can record:
- The condition number
- The full wording of the condition
- The reason for its imposition
- The stage at which it must be satisfied
- The information or work required
- The person responsible for preparing or implementing it
- The target submission date
- The date the information was submitted
- The Planning Authority’s decision
- Any continuing obligations
- Whether written confirmation of compliance has been obtained
Conditions should also be discussed at project meetings and pre-start meetings and should form part of the information formally issued to contractors.
Where specialists are required to prepare drainage, ecology, archaeology, landscape, transport or other technical information, they should be appointed sufficiently early to avoid delaying construction.
Practical Advice for Applicants, Developers and Homeowners
Before beginning development:
- Read the complete planning permission decision notice
- Check every approved plan and document
- Identify all pre-commencement conditions
- Identify conditions applying before occupation or another later stage
- Confirm whether an Initiation of Development Notice is required
- Prepare and maintain a planning conditions schedule
- Allow sufficient time for technical information to be prepared and determined
- Ensure contractors have the correct approved drawings
- Discuss key planning requirements at the pre-start meeting
- Obtain written approvals before reaching controlled stages
- Retain a complete record of correspondence and decisions
- Check work on site against the approved plans and specifications
- Withdraw outdated or superseded drawings from use
Taking these steps can prevent relatively minor misunderstandings from developing into expensive planning, contractual or construction problems.
