Retrospective Discharge of Planning Conditions

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.

What is a planning condition?

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:

  • Pre-commencement conditions — must be discharged before any work starts on site. Common examples: method statements, contamination assessments, archaeology, materials samples, drainage strategies.
  • Compliance conditions — must be discharged at a specified stage during construction (for example, before the building reaches damp-proof course level).
  • Post-completion conditions — must be discharged before occupation or before a specific use begins (for example, landscaping schemes, parking provision, hours of operation).

The standard discharge process

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.

What happens if a condition has not been discharged

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:

  • The planning permission may not have been lawfully implemented. If the breach is fundamental, the courts have held that the consent itself was never validly commenced — meaning the permission could lapse and the works become unlawful in their entirety.
  • The council can issue a Breach of Condition Notice. Unlike an Enforcement Notice, a BCN has no right of appeal — only compliance.

The retrospective discharge process

  1. Identify every unmet condition. Read the original decision notice line by line. Distinguish between pre-commencement, compliance and post-completion conditions.
  2. Gather the supporting evidence. Photographs, dated reports, samples, drawings — whatever the wording of the condition required.
  3. Submit a Section 73 application to discharge the condition. Include a covering letter explaining the timing and confirming the condition is now met.
  4. For minor non-material changes, consider Section 96A instead. This is a faster route for small wording or detail changes.
  5. Engage with the case officer. Be prepared to provide additional evidence on request.

Why it matters for property sales

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.

The honest summary

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.

Frequently asked questions

How long does it take to discharge a planning condition?

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.

What is a Section 73 application?

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.

Can I be prosecuted for not discharging a condition?

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.

Is a Breach of Condition Notice the same as an Enforcement Notice?

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.
