7 Planning Condition Mistakes That Delay Your Build
Last Updated: 28 October 2026
Quick Summary
A planning condition is a legally binding requirement attached to a planning permission that must be met before, during or after building work. To discharge it, you submit a discharge application to your local planning authority identifying the conditions, supply the documents the authority requires, pay the fee and wait for written confirmation before starting work.
- Conditions fall into pre-commencement, pre-occupation and ongoing groups, and each must be discharged.
- Submit a discharge application identifying the conditions you want discharged, with the documents the authority requires.
- Check that submitted plans are consistent with the approved drawings, as mismatches get drawings rejected.
- Wait for written confirmation before starting work, even where a condition seemed minor.
- Expect longer waits where conditions involve drainage, highways or contamination, or documents are incomplete.

What a Planning Condition Actually Requires of You
A planning condition is a legally binding requirement attached to a planning permission that must be met before, during, or after building work. Understanding what is a planning condition and how to discharge it starts here: you cannot simply ignore a condition and start building. Doing so can have consequences for your permission.
Most conditions fall into three groups:
- Pre-commencement conditions: must be discharged before any work starts
- Pre-occupation conditions: must be met before the building is used
- Ongoing conditions: apply during or after construction
The discharge process is how you provide information to your local planning authority about each requirement.
For the wider rules on when approval is needed, see our guide to UK planning permission rules.
The Planning Condition Discharge Application, Step by Step
The discharge process involves submitting an application to your council and waiting for a decision.
Filling In the Application Form
The application should identify the conditions you want discharged. Check what information and documents the relevant authority requires.
Submitting and Paying the Fee
Check the relevant authority's current instructions before submitting.
Planning Condition Discharge Documents You Need to Gather
The documents you need depend on the condition. Check what the relevant authority requires before submitting.
Typical planning condition discharge documents include:
- Site and location plans: scaled and clearly labelled
- Elevations and floor plans: matching the approved drawings
- Materials schedule: samples or specifications where requested
- Landscaping or drainage details: if the condition demands them
- Written statements: explaining how each condition is met
Check that any plans you submit are consistent with the approved drawings.
Planning Condition Discharge Timescale: What to Expect
The time taken to determine a discharge application can vary. Check the relevant authority's current guidance for information about timescales and options if a decision is delayed.
Expect longer waits where:
- The condition involves drainage, highways, or contamination
- Documents are incomplete or unclear
- The council is under heavy workload
You can contact the relevant authority to ask for a status update.
Planning Conditions Before Starting Work: The Rules on Commencement
Planning conditions before starting work are the ones that catch people out. If a pre-commencement condition has not been discharged, check the decision notice and seek advice before starting work.
Read every condition on your decision notice before starting work, and check which conditions require action beforehand.
Common Mistakes That Sink a Discharge Submission
Here are some issues to check:
- Submitting drawings that do not match the approved set
- Discharging some conditions but not all pre-commencement ones
- Starting work before written confirmation arrives
- Ignoring a condition because it seemed minor
These issues can affect your project. For the wider picture on avoiding refusals, read our guide on how to avoid planning permission refusal.
These are the mistakes most likely to hold up or sink a discharge submission.
| Problem | Cause | Fix |
|---|---|---|
| Drawings rejected | Submitted drawings do not match the approved set | Check plans are consistent with approved drawings |
| Incomplete discharge | Some conditions discharged but not all pre-commencement ones | Identify every condition you want discharged |
| Work starts too early | Starting work before written confirmation arrives | Wait for written confirmation before starting |
| Condition ignored | It seemed minor | Read every condition on the decision notice |
