When a local authority grants planning permission for a building project, the permission usually comes with conditions attached. These conditions are legally binding requirements that must be satisfied either before work begins, during construction, or before the development is first occupied. Understanding what they mean and how to address them is essential to keeping your project legally compliant.
Pre-commencement conditions are the most urgent. As the name suggests, these must be discharged, meaning formally approved by the local authority, before any work on site begins. Common examples include the submission and approval of detailed materials samples, drainage strategies, ecological surveys, archaeological watching briefs, and construction management plans. If you start work before a pre-commencement condition has been formally discharged, your planning permission is not yet lawfully implemented, which can create serious legal problems.
The process for discharging conditions involves submitting an application for approval of details to your local planning authority, accompanied by the relevant supporting information such as drawings, specifications, surveys, or statements. Each local authority sets its own fee for this process. The authority then has eight weeks to respond, though in practice responses often take longer.
Some conditions are pre-occupation rather than pre-commencement. These must be satisfied before the building is first used or occupied. For a residential extension, this might include the completion of a landscaping scheme, the installation of a cycle store, or confirmation that a sightline has been cleared. These conditions still need to be managed carefully, as ignoring them puts the occupancy at legal risk.
Other conditions may be ongoing, requiring something to be maintained for the life of the development, such as keeping planting in place, maintaining obscure glazing in a particular window, or not converting a garage to habitable use without further consent. These are enforceable by the council even years after completion.
A good contractor and pre-construction advisor will review your planning permission thoroughly at the start of a project, identify all conditions, and create a clear schedule of what needs to be submitted, approved, and evidenced before or during construction. This prevents the common situation where clients discover a condition late in the process that delays the start of work.
RCB Design & Build reviews all planning conditions as part of our pre-construction process. We help clients understand their obligations, coordinate the submission of condition discharges where required, and make sure no condition is overlooked before work begins on site.
