How to Discharge Planning Conditions After Approval

Planning conditions are typically drafted in one of the following forms, each with different implications for when compliance is needed:

**Pre-commencement conditions**: These must be formally approved by the local planning authority BEFORE any development starts on site. Starting work before a pre-commencement condition has been formally discharged is a breach of planning permission — and any work carried out may be unlawful, potentially requiring retrospective consent or demolition and reinstatement.

• *Typical pre-commencement conditions*:
• •Archaeological survey or watching brief (LPA notified before excavation commences)
• •Construction Management Plan (CMP) — submission of a document describing construction vehicle access routes, delivery times, dust and noise management, site compound location
• •Contamination investigation — required where the site has a known contamination history or is in an area where contamination is suspected (former industrial land, petrol stations, landfill proximity)
• •Drainage design (drainage strategy or SuDS drainage scheme to be submitted before work commences)
• •Arboricultural Method Statement (AMS) and Tree Protection Plan — for sites with trees subject to preservation orders or within Conservation Areas
• •Materials samples — submission of material samples (brick, mortar, roof tile, render colour) for approval before construction commences

**Pre-occupation conditions**: These must be complied with before the approved development is used or occupied, but do not need to be discharged before construction starts.

• *Typical pre-occupation conditions*:
• •Landscaping scheme — implementation of a submitted and approved landscaping plan before occupation
• •Parking provision — confirmation that the specified parking spaces have been constructed and marked
• •Refuse and cycle storage — confirmation that the approved refuse and cycle storage enclosures have been constructed
• •Sound insulation measures — confirmation (acoustic test results) that sound insulation meets specified standards (common in flat conversions and HMO approvals)
• •Boundary treatments — confirmation that specified boundary walls, fences, or hedges have been installed

**Ongoing or management conditions**: These apply throughout the life of the development and do not require a formal discharge application — they require ongoing compliance.

• *Typical ongoing conditions*:
• •'The development shall be used only for [specified use]' (use class restriction)
• •'No external lighting shall be installed without prior approval'
• •'No extension or enlargement of the approved dwellinghouse shall be carried out' (often imposed where the permitted development rights have been removed as a planning condition)
• •'The approved obscure glazing to the side elevation window shall be maintained in perpetuity'

**Self-discharge or compliance conditions**: Some conditions do not require a formal application — they require compliance with a standard or document already approved at planning stage. For example: 'The development shall be carried out in accordance with the approved drawings listed in this decision notice.' No application is needed — just compliance with the approved drawings during construction.

**The application process**: A discharge of condition application is a formal planning application. It is submitted through the Planning Portal (the same portal as planning applications) and is processed by the local planning authority.

• *Documents required*:
• •The application form (online via the Planning Portal)
• •The condition reference number and text of the condition to be discharged
• •The information or documents required by the condition — e.g., for a materials condition: photos of the proposed brick, mortar colour chip, and tile sample; for a Construction Management Plan: the completed CMP document; for a contamination condition: the Phase 1 and Phase 2 environmental report

• *Fee (England, 2025)*:
• •£34 per condition being discharged (for householder applications)
• •Conditions can be grouped — submit all pre-commencement conditions together to minimise fees and delay

• *Timescale*:
• •The LPA must determine within 8 weeks (or 12 weeks for complex EIA conditions)
• •In practice, many LPAs take longer — particularly for complex pre-commencement conditions (contamination, drainage) where specialist officer review is needed
• •The development cannot start until the LPA has confirmed (in writing) that the condition is discharged — a deemed discharge after 8 weeks (if no response received) is available in some cases, but relying on deemed discharge is risky and specialist advice should be sought before doing so

• *Who prepares the discharge application*:
• •For materials conditions: the architect or contractor prepares the material schedule and sample photographs
• •For Construction Management Plans: the contractor prepares the CMP to the LPA's published template where available; some LPAs publish their standard CMP requirements on their website
• •For drainage conditions: a drainage engineer prepares the SuDS drainage scheme or detailed drainage design
• •For contamination conditions: a licensed contaminated land specialist prepares the Phase 1 (desk-top study) and Phase 2 (intrusive site investigation) reports — this is specialist work that cannot be prepared in-house

**Practical workflow for a typical householder planning permission**:

1. *Receive planning decision notice* — read every condition carefully; categorise each as pre-commencement, pre-occupation, or ongoing 2. *Identify all pre-commencement conditions* — these are the critical path items; they must be discharged before work starts 3. *Prepare discharge applications for all pre-commencement conditions simultaneously* — do not apply one at a time; the 8-week determination clock runs from submission date, so simultaneous submission minimises the delay before construction can start 4. *Submit applications and pay fee* (£34 per condition or group of conditions) 5. *Wait for LPA confirmation* — written approval that conditions are discharged 6. *Commence construction* — only after written confirmation is received 7. *Implement pre-occupation conditions during construction* — ensure landscaping, parking, cycle/refuse storage and acoustic measures are installed before the property is occupied 8. *Retain all discharge approvals* — these are required when selling the property to demonstrate planning compliance; store alongside the original planning decision notice

**Common mistakes and consequences**:

*Starting before pre-commencement conditions are discharged*: This is a breach of planning permission. If the LPA discovers work has started before conditions are discharged, they may issue a planning contravention notice, serve an enforcement notice, or (in serious cases) require demolition and reinstatement. The consequences of ignoring pre-commencement conditions are severe — this is not a paperwork technicality.

*Not applying for discharge at all (assuming conditions auto-expire)*: Planning conditions do not expire when the permission expires — they run with the land. A buyer's solicitor querying the planning compliance on a sale will check that all conditions have been formally discharged. An undischarged pre-commencement condition is a planning irregularity that can delay or prevent a sale. Always discharge all conditions and retain the written confirmation.

• **Construction Management Plan (CMP)**:
• CMPs are required on most London planning approvals — particularly in inner London boroughs (Camden, Islington, Hackney, Southwark, etc.) where street access is narrow, neighbouring properties are in close proximity, and construction vehicle movements cause significant disruption. A good CMP covers:
• •Construction vehicle access route and turning point
• •Delivery times (restricted to 8am–6pm Monday–Friday; 8am–1pm Saturday; no Sunday deliveries)
• •Skip and site hoarding licence (from the highway authority)
• •Dust suppression measures
• •Noise management — Plant and equipment noise limits (BS 5228)
• •Worker parking arrangements (parking to be off-site)
• •Contact details for site manager and LPA contact

The CMP must be approved by the LPA before work starts — do not assume it is a formality. Some London borough planning officers review CMPs in detail and may require revisions.

• **Materials conditions — brickwork and render**:
• For extensions in Conservation Areas or where the LPA has required matching materials, a materials condition requires submission of:
• •Brick manufacturer and product code (e.g., Michelmersh Freshfield Lane Multi Stock)
• •Pointing mortar: natural cement manufacturer, aggregate sand description, colour
• •For render: render colour number from the manufacturer's colour range (e.g., Sto Stone N colour range, reference S-0505-Y)

Obtain material approval before ordering — ordering the wrong brick and discovering the LPA requires a different product results in expensive returns and delays.

**Contamination conditions**: Required on any site within the LPA's contaminated land risk area (including former garden sites where chemical contamination from Victorian industry, railway land, or former petrol stations may be present). Phase 1 (desktop) takes 2–4 weeks; Phase 2 (intrusive investigation with trial pits or boreholes) takes 4–8 weeks further, plus laboratory analysis. Budget £2,000–£8,000 for a typical Phase 1 + Phase 2 on a domestic site. If contamination is found, a remediation scheme must be agreed with the LPA's contaminated land officer before construction proceeds.
