Appealing a condition rather than the permission

Appealing against a planning condition puts the whole permission back in play. Under section 79 of the Town and Country Planning Act 1990 an inspector dealing with a section 78 appeal may deal with the application as if it had been made to them in the first instance, which includes refusing it altogether or imposing conditions you like less than the one you objected to. A section 73 application does not carry that risk, because if it fails the original permission survives untouched.

That asymmetry decides most of these cases before the merits are reached.

When a condition can be appealed

Section 78(1)(c) gives a right of appeal against any condition imposed on a grant of permission, including on an approval of reserved matters. The deadline follows the ordinary appeal periods, which are shorter for householder cases than for other development, so check the date on the decision notice rather than assuming six months.

You can appeal one condition or several. What you cannot do is appeal the condition while keeping the permission ring-fenced from the inspector's wider powers.

There is one narrower route worth knowing. Where a condition requires the approval of details and the council refuses that approval, the appeal is against the refusal to discharge rather than against the condition itself, and the permission is not reopened.

The risk that the whole permission is reconsidered

Inspectors do not routinely tear up permissions on a condition appeal. The power exists, it is used rarely, and the Planning Inspectorate's own guidance acknowledges that reopening the principle would usually be unfair where the council granted permission.

Rarely is not never. The risk is real where the permission was granted narrowly, where policy has changed since the grant, or where a statutory consultee has since objected on a point that was overlooked. It is also real where the condition you dislike is the one holding the permission together, such as a restriction on hours, occupancy or the number of units, because removing it changes the development the council actually assessed.

Ask one question before lodging. If the inspector removed this condition, would the permission still be acceptable on the reasoning in the officer report? Where the answer is no, the appeal is asking the inspector to grant a different permission, and it will be treated that way.

Section 73 as the alternative route

An application under section 73 seeks permission to develop without complying with a condition attached to an earlier permission. The council may only consider the question of the conditions, so the principle of development is not reopened.

A successful section 73 application produces a new planning permission sitting alongside the original, with its own conditions and its own reference. That matters for section 106 agreements, which usually need a deed of variation to attach to the new permission, and it matters for the levy, because a new permission can change the chargeable amount.

Section 73 has limits. It cannot be used to alter the description of development, and it cannot be used to extend the time limit for implementation. The Levelling-up and Regeneration Act 2023 added section 73B, a route for varying a permission where the effect is not substantially different from the existing permission, which is broader in some respects than section 73. Check the commencement position and any guidance before relying on it, and follow developments through the planning law timeline.

The third row is the answer for most schemes. Apply under section 73, and if the council refuses, appeal that refusal. You get an inspector's view on the condition with the original permission still in your pocket.

The six tests a condition has to meet

Planning Practice Guidance sets six tests. A condition should be necessary, relevant to planning, relevant to the development permitted, enforceable, precise, and reasonable in all other respects. All six have to be satisfied.

Necessary is the test most conditions fail. A condition requiring materials to be approved where the application already specified them in detail, or requiring a construction management plan on a single-dwelling infill with a wide frontage, adds process without adding control.

Precise is the second most common failure. Conditions that require works to be carried out to the satisfaction of the local planning authority, without stating a standard or a submission requirement, are unenforceable in practice.

Pre-commencement conditions carry an extra requirement. Section 100ZA of the 1990 Act means a pre-commencement condition cannot be imposed without the applicant's written agreement, following a statutory notice procedure. If a pre-commencement condition appeared on your decision notice without that step, say so.

Building the evidence that a condition fails a test

Assertion does not carry a condition appeal. Deal with the tests one at a time, in order, and against the officer report rather than against the decision notice.

1. Find the reason given for the condition in the officer report or the committee minutes. If there is no reason recorded, that is a point in itself, because conditions have to be reasoned.
2. Identify what harm the condition is preventing, and show that the harm does not arise or is controlled elsewhere, by another condition, by a section 106 obligation or by separate legislation.
3. Where the objection is to the burden rather than the principle, offer an alternative wording. Inspectors respond far better to a redrafted condition than to a request for deletion.
4. Where the condition duplicates other regimes, say which one. Building Regulations, environmental permitting, licensing and highway agreements each cover ground that planning conditions sometimes stray into.

Supporting evidence should be proportionate. A condition restricting opening hours is answered with a Noise Impact Assessment showing the rating level at the nearest facade, not with a general statement about local character. A drainage condition is answered with the design, not with a promise.

Choosing between the routes

Cost and time point in different directions. A section 73 application carries a fee and a determination period, then an appeal on top if refused. A direct condition appeal skips one step.

Risk points one way only. If the permission matters, protect it.

There is a middle path that gets used less often than it should. Ask the council to remove or vary the condition informally first, by writing to the case officer with the reasoning and a proposed wording. Councils sometimes agree that a condition was imposed in error, and where the change is trivial a non-material amendment under section 96A may deal with it in weeks rather than months.

Where a condition is holding up the start on site, work out which route delivers a decision inside your programme rather than which one looks least expensive on paper. And keep the supporting evidence base proportionate to the point in dispute, because a condition appeal is not the place to re-argue the whole scheme. If you need a fresh policy case for the varied scheme, a focused Planning Statement will do more work than volume.

This is general guidance, not legal advice. Appeal deadlines and the commencement position on newer statutory routes change, so check with your local planning authority or a qualified professional before relying on it.
