Discharging conditions and the deemed discharge route

Discharge of planning conditions is a separate application to the council, made after permission is granted, asking it to approve the details a condition reserved. It is not automatic and it is not free. For a self-builder, the two things worth knowing up front are that the council has eight weeks to decide most of these applications, and that section 74A of the Town and Country Planning Act 1990 lets you serve a deemed discharge notice when it does not, provided your condition is not on the excluded list.

Start work in breach of a pre-commencement condition and you risk more than a letter. The permission may not have been lawfully implemented, which can leave the whole development unauthorised and expose it to enforcement.

Which conditions need a formal application

Read each condition and ask what it requires. Conditions fall into three practical groups.

Conditions requiring the submission and approval of details, worded "no development shall take place until a scheme for X has been submitted to and approved in writing by the local planning authority", need an application. Conditions that simply limit the development, such as restricting hours of use or requiring the approved plans to be followed, need nothing: you comply with them. Conditions requiring notification, such as telling the council when work starts, need a letter and a diary note.

Pre-commencement conditions are the ones that bite hardest, and since the Neighbourhood Planning Act 2017 a council cannot impose one without the applicant's written agreement. That agreement is often given during determination without much thought. Read the draft conditions the officer sends before you agree to them, because the time to argue that a condition should be pre-occupation rather than pre-commencement is then.

The fee and the determination period

The fee is set nationally and is charged per request rather than per condition, with a lower rate for conditions on a householder permission. National planning fees were uplifted in December 2023 and have been indexed annually since April 2025, so quote the current figure from the published fee schedule rather than an old one.

The determination period for most of these applications is eight weeks from a valid submission. A council can ask for an extension of time in writing, and agreeing one is often sensible where a consultee such as the lead local flood authority needs longer. Agreeing an extension does, though, push back the date from which the deemed discharge route becomes available, so agree it deliberately.

Decisions on condition discharge applications appear on the council's register alongside the original permission, which is the place to check whether a condition on a property you are buying was ever actually discharged. The statutory planning register and what must be on it sets out what the council has to publish.

Grouping conditions in one application

Because the fee is per request, bundling several conditions into one application saves money. It also creates a single point of failure: if the council is content with five sets of details and unhappy with the sixth, the whole request can sit undetermined while the sixth is resolved.

A workable compromise is to group by consultee. Put the drainage and flood conditions in one request so the lead local flood authority sees them together, the ecology and biodiversity conditions in another, and the materials and landscaping conditions in a third. Ask the council whether it will issue a partial discharge covering the conditions it is satisfied with. Many will.

Where the details you want to submit differ from what the condition actually asks for, discharging is the wrong tool. Varying the condition under section 73, or correcting a plan reference under section 96A, is the right one.

The deemed discharge procedure and its exclusions

Section 74A applies where a condition requires the consent, agreement or approval of the local planning authority and the authority fails to notify you of its decision in time. It does not apply if you and the council have agreed in writing that it should not.

The procedure runs like this.

1. Submit a valid application to discharge the condition, with the fee.
2. Wait. The earliest you can give a deemed discharge notice is six weeks beginning with the day the council received the application, or a later date if you agreed one.
3. Give the notice in writing to the authority, identifying the permission, the condition and the application.
4. Specify in the notice the date on which the deemed discharge is to take effect. That date must be at least 14 days after the notice is given, and it cannot fall before the end of the period for determining the application.
5. If the council still has not decided by that date, the condition is treated as discharged.

Keep proof of service and keep the acknowledgement. A deemed discharge only helps later if you can show when the notice was given.

Conditions that cannot be deemed discharged

Schedule 6 to the Town and Country Planning (Development Management Procedure) (England) Order 2015 lists the conditions the route does not reach. Read the Schedule itself rather than a summary of it, because the categories are specific and short, and they include cases such as permissions for development that was subject to environmental impact assessment and cases where an appropriate assessment was required under the Conservation of Habitats and Species Regulations 2017.

The practical consequence for a small site is that your ecology and drainage conditions may be exactly the ones you cannot force. If a biodiversity gain plan or a protected species mitigation scheme is holding the site up, the answer is engagement with the officer and the consultee, not a notice. Where mandatory biodiversity net gain applies, the biodiversity gain condition has its own approval route and its own evidence, set out on the Biodiversity Net Gain Assessment page.

Evidence to submit with each condition

Councils refuse or sit on discharge applications mostly because the submission does not answer the condition on its own terms. Two habits fix that.

First, write a short covering schedule that quotes each condition in full, lists the documents submitted against it, and states in one sentence how each document satisfies the wording. An officer who can tick the condition off without hunting through a folder will decide faster.

Second, submit what the condition asks for rather than what you have. A condition requiring "a scheme of hard and soft landscaping including species, sizes, densities and a five-year maintenance programme" is not discharged by a planting plan without the maintenance programme. Where a condition asks for something you think is unnecessary or already covered, say so explicitly in the covering note and explain why, rather than leaving the gap silent.

Cross-refer back to the reasoning in your Planning Statement where the condition repeats a commitment made during determination. Officers change, and the officer discharging the condition may not be the one who granted permission.

An illustrative sequence for a single plot. Permission granted in March with six conditions, three of them pre-commencement covering surface water drainage, construction management and materials. The applicant agrees the drainage strategy with the lead local flood authority before submitting, groups drainage and construction management in one request, and submits materials separately with samples. The materials condition is discharged in five weeks, the drainage in nine after an agreed extension. Treat that as illustration of the sequence rather than a timetable to rely on.

What to do when the council goes quiet

Chase the case officer, in writing, at week five. Ask whether the consultee response has come back and whether an extension of time would help. Escalate to the team leader at week seven if there is no answer.

Then decide. If the condition is on the excluded list, a notice is not available and the options are negotiation, a section 73 application, or an appeal against non-determination. If it is not excluded, serve the notice and diarise the effective date. And be honest about the risk: a deemed discharge gets the condition off the permission, but it does not give you the council's agreement to the details, and any later dispute about whether the development was built in accordance with them will be argued on the submitted documents alone.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it.
