Drafting the supporting note for a discharge of conditions

A discharge of conditions application is not a second planning application. The authority has already decided that the development is acceptable in principle, and what it is approving now is a specification: a material, a level, a strategy, a survey result. Write the supporting note to that narrow question and the request is usually determined without correspondence. Write it as a restatement of the planning case and you invite a holding response, because the officer cannot find the detail they were told to approve.

The condition wording is the brief. Everything else is background.

What the authority is actually approving

Applications for approval of details reserved by condition are made under the Development Management Procedure Order 2015, and they ask the authority to confirm that submitted details satisfy a specific condition on a specific permission. The authority cannot use the request to revisit the principle of development, to impose new requirements that the condition does not support, or to reopen a design matter already settled in the approved drawings.

It can, and routinely does, refuse to discharge where the submitted details do not actually answer the condition. That is the failure mode to design against. A condition requiring "samples of all external materials to be submitted and approved" is not discharged by a schedule of manufacturer names, because a schedule is not a sample.

Conditions imposed before commencement need the applicant's written agreement under the pre-commencement condition rules, so where a pre-commencement condition appears on a decision notice without that agreement there is a prior question worth asking. Most are agreed during determination, often by email, and the file should record it.

Reading the condition wording as a specification

Break each condition into four parts before you draft anything.

1. The trigger. Before development begins, before works above damp proof course, before first occupation, before the use begins, or within a stated period. The trigger sets your deadline and sometimes your evidence, because a condition triggered before occupation cannot be discharged with pre-construction photographs.
2. The deliverable. A scheme, a strategy, a sample, a survey, a plan, a detail at a stated scale. Match the noun exactly.
3. The approving party. The local planning authority, or the authority in consultation with the highway authority or the lead local flood authority. Where a consultee is named, send them the material directly as well, because the eight weeks runs whether or not the consultee replies promptly.
4. The compliance obligation. Most conditions end with words to the effect that the approved details shall thereafter be implemented and maintained. That obligation survives the discharge and binds the occupier.

Quote the condition in full at the head of your note, then answer it clause by clause under its own subheadings. An officer checking twelve conditions on a Friday afternoon should be able to tick each one against a numbered response.

One application or several

The fee is charged per request, not per condition, and that creates a real tactical choice.

Bundling every condition into one request costs less and gives the officer a single file. It also means one unresolved condition holds up the whole determination, and on a pre-commencement bundle that stops the site. Splitting the requests isolates the risk: the conditions with clean, documentary answers go in together, and anything that depends on a survey season, a sample panel or a third party goes separately.

The practical rule is to group by risk rather than by trigger. Put the certain items together, and give each uncertain item its own reference so a problem with the drainage detail does not delay the materials approval you need to order bricks.

Fees for approval of details are set in the national fee regulations and indexed annually, with a lower figure for householder permissions. Check the current schedule rather than reusing a figure from a previous job.

The eight weeks, and deemed discharge

The authority has eight weeks to determine a request for approval of details, running from receipt of a valid application with the correct fee. An incomplete submission does not start the clock, which is the most common cause of a programme slipping without anyone noticing.

There is a deemed discharge route under the Town and Country Planning Act 1990 for certain conditions, where the applicant serves a notice and the condition is treated as discharged if the authority still does not determine the request. It does not apply to everything. Whole categories are excluded, including conditions on development subject to environmental impact assessment and conditions dealing with particular technical subjects, and the excluded list is set out in the procedure order. Read it before you rely on the route, and serve the notice precisely, because a defective notice achieves nothing and costs weeks.

In practice a polite chase at week six, naming the conditions and attaching the receipt, resolves more cases than a deemed discharge notice does.

Evidence that has to be physical, photographic or sampled

Some conditions cannot be discharged on paper, and this is where an AI-assisted draft reaches its limit.

• Material samples usually mean physical samples or an on-site sample panel, viewed by the officer. Photographs of a brick are not a sample, and a conservation officer will say so.
• Window and door details are normally wanted as sections at a large scale, typically 1:5 or 1:2, showing reveal depth, frame profile and glazing line.
• Hard landscaping and boundary treatments want product specifications plus a laid sample where the setting is sensitive.
• Ecological conditions want a licensed or competent specialist's report, and for bats an emergence survey can only be done between May and September.
• Construction management and traffic conditions want a plan signed off by the contractor who will actually implement it.
• Verification conditions on contaminated land want laboratory certificates against the approved remediation criteria.

A draft can structure the submission, quote the condition, cross-refer to the approved drawings and set out what is enclosed. It cannot produce the sample panel, carry out the survey or exercise the specialist judgement, and it should not pretend to. Where a drafting tool inserts a "[TO BE CONFIRMED]" flag against a missing fact, that flag is the honest answer, and it needs resolving before submission rather than after. The wider point about what drafts get right about structure and wrong about evidence applies with particular force here.

Where a condition needs a signed professional opinion, the review route matters. PlanScope's professional directory exists for that step, and the sign-off is the specialist's, not the draft's.

Keeping a discharge record for the file

Conditions outlive the people who wrote them. Build the schedule once and maintain it.

A single spreadsheet with one row per condition, carrying the condition number, its text, the trigger, the discharge application reference, the decision date and the location of the approved documents, is what a buyer's solicitor will ask for on sale, what a building control inspector will want on site, and what you will need if an enforcement query arrives in four years. Attach the approval notices to it.

Invalid submissions are the other avoidable cost, and the reasons overlap heavily with those for a returned application, covered in why planning applications are returned as invalid. Wrong fee, missing form, no reference to the parent permission, conditions quoted by the wrong number.

If you are assembling a discharge submission and want a structured first draft of the supporting note, see PlanScope pricing for the one free report, pay per report and Professional options, then send the draft to a qualified reviewer where the condition calls for one.

This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval. For specialist technical reports, qualified professional input may be required.
