Understanding planning conditions

Planning conditions are requirements attached to a planning permission that must be met before, during, or after development. They are used to make a development acceptable that would otherwise be refused.

Understanding your conditions is essential - breaching pre-commencement conditions is a criminal offence and can invalidate your entire permission.

Types of planning conditions

Common conditions explained

Pre-commencement conditions

These must be formally discharged before any work begins on site, including demolition, site clearance, or groundworks. Common examples:

• Construction management plan - how you will manage construction traffic, noise, dust, and working hours
• Archaeological investigation - a programme of archaeological works before ground disturbance
• Contamination investigation - detailed site investigation and remediation strategy
• Drainage strategy - detailed sustainable drainage design
• Ecological mitigation - protected species mitigation before habitat disturbance

Before above slab level

These must be discharged before construction rises above ground floor level:

• External materials - samples or details of bricks, roof tiles, windows, and other external materials
• Detailed landscaping - full planting schedule, hard landscaping details, boundary treatments

Before occupation

These must be discharged before anyone uses or occupies the development:

• Highway works - access road, visibility splays, and footpath connections completed
• Parking - car parking and cycle storage provided as approved
• Open space - communal areas and play facilities completed

Compliance conditions

These do not require formal discharge but must be complied with throughout:

• Approved plans - development must match the approved drawings
• Working hours - typically 8am-6pm Monday to Friday, 8am-1pm Saturday, no work on Sundays or bank holidays
• Noise limits - maximum noise levels at site boundaries

Discharging your conditions

Challenging unreasonable conditions

Planning conditions must meet six tests set out in national policy. A condition must be:

1. Necessary
2. Relevant to planning
3. Relevant to the development permitted
4. Enforceable
5. Precise
6. Reasonable in all other respects

Your options if a condition is unreasonable

• Discuss with the case officer - explain why the condition is problematic and suggest alternatives
• Apply under Section 73 - apply to vary or remove the condition. This creates a new permission with amended conditions
• Appeal - you can appeal against any condition imposed, though this puts the entire permission at risk
