Planning permission granted without conditions is rare. Almost every approval — from a householder extension to a major development — comes with a schedule of conditions that must be complied with. Getting these right is not optional: breaching a planning condition can expose you to enforcement action, injunctions, and in extreme cases the demolition of works already carried out.
This guide explains what planning conditions are, when you need to discharge them, how to vary or remove them, and what to do when things go wrong.
What Are Planning Conditions and Why Are They Imposed?
A planning condition is a legally binding requirement attached to a planning permission that must be fulfilled before, during, or after development. They are imposed under section 72 of the Town and Country Planning Act 1990.
The legal tests for imposing conditions are set out in Planning Practice Guidance (PPG) (which updated and partially replaced Circular 11/95) and require that conditions must be:
- Necessary — would development be refused without the condition?
- Relevant — to planning and to the development permitted
- Precise — clearly worded to be enforceable
- Enforceable — capable of being monitored and acted upon
- Reasonable — not unduly burdensome in proportion to the planning reason
Common examples include:
- "No development shall commence until samples of the facing materials have been submitted to and approved in writing by the local planning authority."
- "Prior to first occupation, the access as shown on Drawing No. XX shall be constructed to adoptable standards."
- "The building shall be used for residential purposes only."
Two Types of Action
There are two distinct legal processes for dealing with planning conditions, and it's important not to confuse them:
| Action | Purpose | Legal Route |
|---|---|---|
| Discharge a condition | Satisfy the requirement so works can proceed | Application under s.73A (or informally by submission) |
| Vary or remove a condition | Change the substance of what the condition requires | Application under s.73 of the TCPA 1990 |
Discharging Pre-Commencement Conditions
Pre-commencement conditions are the most important category. They contain the phrase "no development shall commence until..." or similar wording. If you break ground before a pre-commencement condition is discharged, you are in breach of planning permission from day one — the permission may be treated as void, and all subsequent works will be unlawful.
Common pre-commencement condition topics:
- Materials and appearance (samples to be submitted and approved)
- Highways and access (construction management plan, swept path analysis)
- Ecology (protected species surveys, mitigation strategy)
- Contamination (Phase II site investigation, remediation strategy)
- Archaeology (written scheme of investigation)
- Tree protection (arboricultural method statement, protective fencing)
- Drainage (surface water drainage scheme, SUDS design)
How to Discharge a Condition
- Prepare the required information — for a materials condition, this typically means physical samples or a specification document. For an ecology condition, it may require a licensed ecologist's report.
- Submit an application to discharge conditions via the Planning Portal. In England, the fee is £43 per request for householder applications and £145 per request for other developments (as of 2024). Multiple conditions can be grouped in one application.
- The LPA has 8 weeks to determine the application (or 12 weeks for complex cases where the discharge requires assessment).
- Written approval is required — do not start works on the basis of a telephone conversation or officer's verbal confirmation.
How to Write a Strong Discharge Application
- Quote the condition number and wording verbatim at the top of your submission.
- Address every element of the condition — if the condition requires both a sample and a specification, provide both.
- Provide visual context — photographs, plans, and sample boards are far more persuasive than text alone.
- Reference pre-application advice if the officer has informally confirmed an acceptable approach.
- Avoid vague descriptions — "natural slate from a local supplier" is not sufficient; specify the source quarry, size, thickness, and fixing method.
Varying or Removing Conditions: Section 73 Applications
If you want to change what a condition requires — or remove it entirely — you need a section 73 application. This is an application for planning permission to develop without complying with the condition, or with a modified condition.
Section 73 can only be used to vary conditions, not to vary the description of the development itself (that requires a fresh full application).
The s.73 Process
- Identify the condition to be varied or removed and draft the replacement wording (or the reason for removal).
- Prepare supporting documents — a planning statement explaining why the modified condition is acceptable, any technical reports addressing the original planning concern.
- Submit via the Planning Portal. The fee is £234 for householder applications and £586 for other applications in England (2024 fees). Wales uses separate fee scales.
- 8-week determination target — the LPA must consult all original consultees if varying a condition that was attached following their advice.
- A new planning permission is issued incorporating the varied condition. This is a new standalone permission — keep it alongside the original.
Pre-Application Advice for s.73
Pre-application advice (typically £50–£200 for householder cases) is particularly valuable before a s.73 application. If the officer informally confirms that the variation is acceptable, the application can be drafted accordingly. This reduces the risk of refusal.
Appealing a Refused Discharge or s.73 Application
If your discharge application or s.73 application is refused, or not determined within the statutory period, you can appeal to the Planning Inspectorate. In England:
- Appeal online at appeals.planninginspectorate.gov.uk
- Most condition discharge appeals are handled by written representations (cheapest and fastest — target 24 weeks)
- The Planning Inspectorate can allow the appeal and confirm the condition as discharged or varied, or dismiss it
Costs awards against the LPA are available if the authority behaves unreasonably, but this is a high bar to meet.
Consequences of Breaching a Planning Condition
This is not a minor administrative issue. Under section 179 of the TCPA 1990:
| Consequence | Detail |
|---|---|
| Planning enforcement notice | Requires you to undo the breach or cease the use |
| Stop notice | Prevents further development (compensation if served incorrectly) |
| Breach of condition notice | Simpler enforcement tool — no appeal right as to the original condition |
| Injunction | County or High Court can compel compliance |
| Criminal prosecution | Fine for non-compliance with enforcement notice |
| Demolition order | In serious cases, the LPA can require demolition of unlawful works |
Planning enforcement in England does not expire for breaches of condition (except in the limited case of the 10-year rule for a material change of use to a dwelling, and the 4-year rule for operational development — but these do not apply to condition breaches in most circumstances). The safest approach is always to discharge conditions before starting work.
Costs Summary
| Action | Fee (England, 2024) | Typical Professional Costs | Timescale |
|---|---|---|---|
| Pre-commencement condition discharge | £43 (householder) / £145 (other) | £200–£800 (depending on complexity) | 8 weeks |
| s.73 condition variation | £234 (householder) / £586 (other) | £500–£2,000 | 8 weeks |
| Pre-application advice | £50–£200 | Included in planning consultant fee | 4–6 weeks |
| Planning Inspectorate appeal | No fee | £1,000–£3,000 (written reps) | 24–40 weeks |
| Breach of condition retrospective discharge | Same as standard | Higher (urgency premium) | Variable |
If you are buying a property where planning conditions were attached to past works, instruct your solicitor to check that all conditions have been properly discharged. Unremedied conditions are a title defect that can complicate mortgaging and resale.
