What to do when a pre-commencement condition was missed and the works have already started.
Retrospective discharge of conditions is the process for satisfying a planning condition after the development has already started or been completed. The most common situation is a pre-commencement condition (for example, a method statement or a materials sample) that should have been discharged before any work began. The council can still consider the application and accept the evidence — but the breach is technically already in place, so the application has to be drafted as a structured response to that position rather than a routine submission.
A planning condition is a directive imposed by the local planning authority when granting permission. Conditions are used to control how a development is carried out, what it looks like, when it can operate, and what supporting information has to be provided. They have full legal force — breaching a condition is a breach of planning control under section 171A TCPA 1990.
Conditions fall into three timing categories:
Discharging a condition is a formal application to the council under section 73 of the Town and Country Planning Act 1990. You submit the supporting documents the condition requires (drawings, surveys, reports, samples), pay the council fee, and the council assesses whether the condition has been satisfied. The statutory determination period is 8 weeks — though in practice it can be longer if the council asks for more information.
If you have started work without discharging a pre-commencement condition, you are technically in breach. The legal effect can be serious in two ways:
Undischarged conditions are one of the most common reasons conveyancing transactions stall. Buyers' solicitors routinely check the planning history of a property and flag any conditions that have not been formally discharged. Mortgage lenders may decline to lend until the conditions are resolved. Getting the discharge formalised is not just good practice — it directly affects the property's marketability and value.
Retrospective discharge of conditions is the system's built-in fix for pre-commencement breaches. It works most of the time, provided the evidence is properly assembled and the application engages directly with the wording of the condition. The longer you leave it, the more complicated the position becomes — particularly if a Breach of Condition Notice is on the way.
The statutory target is 8 weeks from validation, though in practice 6 to 10 weeks is normal. Complex conditions involving statutory consultees (highways, ecology, conservation) can take longer.
A Section 73 application is the formal route under the Town and Country Planning Act 1990 for varying or discharging a planning condition. It is the standard mechanism for both prospective and retrospective discharge.
Not for the breach itself. You can only be prosecuted if you fail to comply with a Breach of Condition Notice once it has been served. The fine on conviction is at the discretion of the magistrates' court.
No. A Breach of Condition Notice has no right of appeal — you must comply within the period stated. An Enforcement Notice carries a 28-day right of appeal to the Planning Inspectorate.
