Planning Condition Compliance When Selling Your Home in North London

Introduction

When planning permission is granted for works to a residential property in north London, conditions are routinely attached to the permission. Some conditions are pre-commencement (must be discharged before any work begins), some are pre-occupation (must be complied with before the completed works are used), and some are ongoing (continue to apply to the property indefinitely). When a property subject to conditions is sold, the purchaser's solicitor will check whether those conditions have been properly discharged. Outstanding undischarged conditions are a common cause of delay and renegotiation in property transactions. This guide explains how planning conditions work and what is required at sale.

Types of Planning Condition

Pre-Commencement Conditions

Conditions that must be complied with before any works begin — the most restrictive type. Common pre-commencement conditions include:

• Submission and approval of construction management plan or construction logistics plan
• Submission and approval of materials samples or specifications
• Archaeological watching brief arrangements agreed before excavation
• Tree protection scheme agreed before any site works

If works commenced without discharging a pre-commencement condition, the planning permission may have been breached — creating an enforcement risk and potentially invalidating the permission entirely.

Pre-Occupation Conditions

Conditions that must be complied with before the approved space is occupied or used. Common examples:

• Completion of landscaping scheme before first occupation
• Provision of secure cycle storage before occupation
• Installation and commissioning of sound insulation before occupation
• Submission of as-built drawings and energy performance certificate before occupation

Ongoing Conditions

Conditions that apply permanently to the property — restricting use, requiring maintenance, or limiting future alterations:

• Permitted development rights removed — the permission removes the right to carry out certain types of works without a new application
• Use restrictions — limiting residential use to a single household or preventing subdivision
• Maintenance obligations — requiring trees or landscaping to be maintained in a specified form
• Restrictions on working hours or operations

Formal Discharge of Conditions

Where a planning condition requires "details to be submitted and approved," the formal mechanism for discharging it is an application to discharge planning conditions — submitted to the LPA with the required documentation. The LPA reviews the submission and issues a Discharge of Condition notice confirming that the condition has been satisfied. This formal discharge notice is the evidence required by a purchaser's solicitor to confirm that the condition has been properly met.

The application fee for discharging conditions is £34 per request (2026 rate) for householder applications. The LPA has 8 weeks to determine the application. Where multiple conditions require discharge, they can typically be addressed in a single application.

What Purchasers' Solicitors Look For

When the property information form (TA6) and planning documentation are reviewed by the purchaser's solicitor, they will identify:

• All planning permissions affecting the property — particularly any recent permissions with conditions
• Whether pre-commencement conditions were discharged before works commenced (evidence: the formal discharge notice and any relevant correspondence)
• Whether pre-occupation conditions were discharged before the property was occupied
• Whether any ongoing conditions affect what can be done with the property

If conditions were not formally discharged, the solicitor will typically require either: (1) evidence that the condition has been complied with and the LPA is satisfied (a discharge application and decision), or (2) planning indemnity insurance covering the risk of enforcement action related to the undischarged condition.

Addressing Outstanding Conditions Before Sale

Retrospective Discharge Application

For conditions that required approval of details — materials, landscaping scheme, construction management plan — that were never submitted, a retrospective discharge application can be made. The LPA will review the actual position and confirm whether the condition is satisfied or whether works are required. For conditions that have been complied with in fact (e.g., landscaping was installed as required) but the formal discharge was never applied for, a retrospective application typically succeeds promptly.

Planning Indemnity Insurance

Where a retrospective discharge application is not practical — typically because the works are old, the relevant LPA officer is no longer available, or the formal discharge evidence cannot be produced — planning indemnity insurance covers the risk of enforcement action. The policy is acceptable to most purchasers' solicitors and lenders. See our guide on planning indemnity insurance for detail.

Conditions Affecting Future Works

Ongoing conditions that restrict the property's development potential — such as conditions removing permitted development rights — must be disclosed to the purchaser. They represent an important limitation on the future flexibility of the property. A buyer who purchases a north London house expecting to extend under permitted development rights but who discovers after purchase that a condition removes those rights will have a valid claim for misrepresentation if the condition was known to the seller and not disclosed.

Conclusion

Planning condition compliance is a routine part of a property transaction where planning permissions are in place, but it catches many sellers by surprise because conditions imposed years ago on previous planning permissions may never have been formally discharged. A pre-sale review of planning history — identifying all outstanding conditions and either discharging them formally or obtaining indemnity insurance — avoids this being discovered during the transaction when it can cause delay, renegotiation, or collapse of the sale. An architect with experience of north London planning can carry out this review quickly and advise on the appropriate route for each condition.
