Planning Condition
/ ˈplænɪŋ kənˈdɪʃən /
Also known as: condition, pre-commencement condition, discharge of condition
Definition
A planning condition is a legal requirement attached to a planning permission that must be complied with alongside carrying out the permitted development. Conditions may be pre-commencement (must be discharged before any work starts), pre-occupancy (before the building is used), or ongoing (throughout the life of the development). Common conditions require approval of materials, drainage details, landscaping, construction management plans, or restrict hours of use. Non-compliance is a breach of planning control. Discharging a condition requires a formal application to the local planning authority with supporting information, and written approval before the relevant activity proceeds. Conditions must meet NPPF tests - necessary, relevant, precise, enforceable, and reasonable - and can be challenged by appeal or section 73 application.
In practice
Failing to discharge pre-commencement conditions before starting work is one of the most common planning compliance errors made by self-builders and small developers. The decision notice lists all conditions with their condition numbers; any condition requiring action before development commences must be formally discharged before groundworks, foundations, or any other construction activity begins. Starting on site without formal written discharge of pre-commencement conditions can result in enforcement action and, in the worst case, a requirement to demolish the completed development.
When reviewing a planning permission before starting work, read every condition carefully and prepare a conditions register - a checklist of every condition, what it requires, who is responsible for discharging it, and its status. Pre-commencement conditions should be discharged in parallel with detailed design and procurement, so they do not delay the construction start. Conditions requiring approval of materials (brickwork, roof tiles, window frames) are particularly common in conservation areas and can delay the start if not applied for early.
