Conditions imposed by an inspector after an appeal is allowed
When an appeal is allowed the inspector chooses the conditions, and the council administers them afterwards. Here is how to influence the schedule during the appeal and work through it once the decision letter lands.
When an inspector allows a planning appeal, the permission that results is the inspector's permission, and every condition on it was chosen by the inspector rather than by the council. That matters in practice. The conditions may not be the ones the council proposed, they may be worded differently, and the three-year clock runs from the date of the appeal decision rather than from anything the council did. The council still administers them afterwards, which is where most of the friction happens.
Read the schedule of conditions at the back of the decision letter before you read anything else in it.
Where the inspector's conditions come from
Section 79 of the Town and Country Planning Act 1990 lets the appeal decision-maker deal with the application as if it had been made in the first instance. So the inspector can grant permission subject to any condition the council could have imposed, including conditions nobody suggested.
The tests are the six in national policy and the Planning Practice Guidance on the use of planning conditions: necessary, relevant to planning, relevant to the development permitted, enforceable, precise, and reasonable in all other respects. An inspector who wants a condition that fails one of those tests will usually say so and leave it out, and will often explain the reasoning in the body of the letter. That explanation is useful later when you are arguing with a case officer about what a condition actually requires.
Where a condition would be unreasonable as drafted, inspectors frequently rewrite it rather than delete it. The intent survives, the trigger point moves, and the wording tightens.
Commenting on draft conditions during the appeal
This is the stage most appellants underuse. The council is asked to put forward its suggested conditions with its appeal statement, and you get to respond to them without prejudice to your case that permission should be granted unconditionally.
Do it properly and specifically:
- Take each suggested condition and say whether you agree, agree with amendment, or object, with a reason grounded in the six tests.
- Move pre-commencement triggers to a later stage wherever the substance allows. "Prior to occupation" and "prior to works above damp proof course" are far easier to live with than "prior to commencement".
- Offer alternative wording in full, so the inspector can lift it straight into the schedule.
- Where a condition would require something already fixed by the approved drawings, say so and ask for it to be deleted as unnecessary.
At an inquiry there is normally a conditions session and an agreed list attached to a statement of common ground. Agreeing conditions is not conceding the appeal, and inspectors are used to appellants doing both at once.
Reading the decision letter for the trigger points
Once the decision arrives, go through the schedule and tabulate the conditions by trigger. The categories that matter are: before development begins, before works above ground level, before a specified stage such as installation of external materials, before first occupation or first use, and conditions that bite for the life of the development.
Only the first category blocks a lawful start. Get those identified on day one, because they set the critical path. A pre-commencement condition requiring an approved construction management plan means the Construction Management Plan has to be written, submitted, considered and approved before a machine turns up, and eight weeks is a realistic allowance for each application.
Two other things to note in the letter. Check whether the inspector has attached the approved drawing numbers in a compliance condition, because those numbers define what you have permission for. And check the date, since the time limit for implementation runs from it.
Discharging conditions with the council afterwards
The inspector does not deal with the details. Applications to approve matters reserved by condition go to the local planning authority under the Town and Country Planning (Development Management Procedure) (England) Order 2015, with a fee per request set by the national fee regulations and indexed annually, so check the current schedule before you budget.
Councils sometimes treat an appeal-won permission coolly. That is not a reason to submit thin discharge applications. Address the exact words of the condition, quote them at the top of your submission, and set out how each element is satisfied. Where the inspector explained the purpose of the condition in the decision letter, quote that too, because it constrains what the council can reasonably ask for.
England has a deemed discharge mechanism under section 74A of the 1990 Act for certain conditions, which lets an applicant serve a notice and treat the details as approved if the council does not determine the application in time. It does not apply to every condition, and the exclusions are wide, so read the current rules before relying on it. Used sensibly it is a lever, and simply mentioning that you are aware of it sometimes moves a stalled application along.
Section 73 after an appeal
A condition imposed by an inspector can be varied or removed on an application to the council under section 73 of the 1990 Act. The council considers only the question of the conditions, not the principle of development, and a refusal carries its own right of appeal.
There is a limit worth knowing. Following Finney v Welsh Ministers in the Court of Appeal, section 73 cannot be used where the variation would conflict with the operative description of the development in the permission. If the change alters what was permitted rather than how it is delivered, section 73 is the wrong tool and you need a fresh application. The Levelling-up and Regeneration Act 2023 created a further route for varying permissions, but it depends on regulations, so confirm whether it is in force before you plan around it.
Expect the council to look at the whole condition schedule when it grants a section 73 permission, since the new permission carries its own set of conditions. Ask for the schedule to be reproduced unchanged apart from the condition in dispute, and check the decision notice carefully when it arrives.
Timing the start on site
The permission granted on appeal carries a time limit, normally three years from the decision date for a full permission. Work backwards from that date.
A worked sequence, illustrative only, for a scheme with three pre-commencement conditions: allow two weeks to commission the reports, four weeks for the specialists to produce them, one week to compile and submit, eight weeks for determination, and a contingency of four weeks for a request for further information. That is nineteen weeks before a spade goes in the ground, and it assumes the surveys are not season-limited. Add an ecology condition that needs a bat emergence survey and the earliest start may be the following May.
Set out the appeal history and the condition position in the Planning Statement for any subsequent application on the site, because the next officer will not have read the inspector's letter and the reasoning in it is the strongest material you have.

Frequently asked questions
Can an inspector impose a condition the council never asked for?
Yes. Section 79 of the Town and Country Planning Act 1990 allows the appeal decision-maker to deal with the application as if it had been made in the first instance, so any condition the council could lawfully have imposed is available. The condition still has to meet the six tests in the Planning Practice Guidance on the use of planning conditions.
Should I comment on the council's suggested conditions during the appeal?
Yes, and without prejudice to your case that permission should be granted. Take each suggested condition, say whether you agree, agree with amendment or object, give a reason grounded in the six tests, and offer alternative wording in full. Moving pre-commencement triggers to a later stage is usually the most valuable change you can secure.
Who discharges conditions on a permission granted at appeal?
The local planning authority does. Applications to approve matters reserved by condition go to the council under the Development Management Procedure Order 2015, with a fee per request set by the national fee regulations and indexed annually. The inspector has no further role once the decision letter is issued.
Can I use section 73 to change a condition an inspector imposed?
Usually yes. A section 73 application goes to the council, which considers only the conditions rather than the principle of development, and a refusal carries a right of appeal. Following Finney v Welsh Ministers, section 73 cannot be used where the change would conflict with the operative description of the development in the permission.
When does the three-year time limit start after an appeal?
From the date of the appeal decision, not from the council's earlier refusal. Work backwards from that date and allow realistic time for every pre-commencement condition, including about eight weeks for each discharge application and any seasonal constraint on ecology surveys, which can push a start into the following spring.
