Planning permission can look like a successful outcome until the conditions are read closely. A condition may restrict opening hours, require expensive technical work, control occupancy, limit deliveries or prevent an important part of the approved scheme from operating as intended. For a homeowner, landlord, developer or business, the practical question is whether the condition must simply be accepted or whether it can be challenged.

In England, there are several possible routes. The right one depends on when the condition was imposed, whether development has started and whether the applicant wants to challenge the original permission or seek a later variation. A planning condition appeal solicitor or another planning-law professional can help assess those options. Aldwych Legal supports clients across England with planning disputes, appeals and strategic case preparation.

Start With the Six Tests for Planning Conditions

National planning guidance says planning conditions should be imposed only where they satisfy six tests. A condition must be necessary, relevant to planning, relevant to the development being permitted, enforceable, precise and reasonable in all other respects.

Those tests matter where a condition appears disproportionate, vague or unrelated to the planning harm it is supposed to address. A restriction may have a legitimate purpose but still be wider than necessary. For example, a condition intended to protect neighbouring amenity may need to control operating hours, but the exact hours imposed should still be capable of justification.

Aldwych Legal can support evidence-led preparation where the wording of a condition, the officer report and the planning history need to be reviewed together.

Understand Why the Condition Was Imposed

Before deciding how to respond, read the decision notice alongside the planning officer’s report, committee minutes where relevant, approved plans and consultation responses.

The reason for the condition is important. A noise restriction may protect residential amenity. A landscaping condition may address visual impact. A delivery restriction may respond to highway or neighbourhood concerns.

If the objective is legitimate but the wording makes the development commercially or practically unworkable, the strongest response may be to propose a narrower condition rather than seek complete removal. Evidence should explain how the planning concern can still be addressed.

A Direct Section 78 Appeal Is One Option

Section 78 of the Town and Country Planning Act 1990 allows the original applicant to appeal where planning permission has been granted subject to conditions to which the applicant objects.

A direct condition appeal has an important strategic consequence. The Inspector re-determines the planning application as a whole rather than considering only the disputed condition. Government guidance therefore warns that the Inspector could ultimately refuse planning permission and reverse the local authority’s decision.

An applicant who wants to challenge planning conditions through a direct appeal should weigh that risk carefully. Under the current post-1 April 2026 procedural guide, appeals against a grant of planning permission subject to objectionable conditions are generally required within six months of the decision notice. A related enforcement notice can shorten the period in specified circumstances, so the applicable deadline should still be checked for the individual case.

For applications submitted on or after 1 April 2026, an appeal against permission granted subject to objectionable conditions generally follows the Part 1 written-representations procedure, unless the Planning Inspectorate decides another procedure is more appropriate.

Section 73 Can Be a More Focused Route

Where planning permission already exists, section 73 allows an application to be made to develop without complying with one or more conditions attached to that permission. In practice, it can be used to vary or remove conditions.

Unlike a direct appeal against the original permission, a section 73 application is focused on the condition or conditions in question. Government guidance says the local planning authority must consider the disputed condition or conditions rather than completely reconsider the original application.

Section 73 has limits. It cannot be used to change the operative description of the development, and it cannot extend the time limit for starting development or for submitting reserved matters.

If permission is granted under section 73, it creates a new, independent planning permission with the revised conditions. The original permission remains in existence. That can be useful where the developer wants a targeted change without giving up the earlier permission.

Where the options need to be compared, challenging planning conditions can help explain how direct appeals and section 73 applications fit within a wider planning dispute.

What if the Council Refuses the Section 73 Application?

A refusal of a section 73 application can itself be appealed to the Secretary of State under section 78. Government guidance confirms that the appeal focuses on the condition or conditions in question rather than reopening the entire original planning permission in the same way as a direct appeal against the original conditional grant.

For section 73 applications submitted on or after 1 April 2026, the appeal normally falls within the Part 1 written-representations procedure. That matters because new evidence not previously considered by the local planning authority is generally restricted under Part 1.

Aldwych Legal can support strategic case preparation where an applicant needs to decide whether to appeal a refusal or return to the council with a better-evidenced proposal.

Evidence Should Show Why the Condition Is Unworkable

Calling a condition “unreasonable” is rarely enough. The case should explain the real effect of the restriction and why a different condition would still achieve the planning objective.

Depending on the development, useful evidence may include:

• viability or cost information;
• transport or servicing evidence;
• noise assessments;
• operational management plans;
• design drawings;
• heritage or landscape material; and
• evidence of changed circumstances.

Technical evidence should be tied to the purpose of the condition. If the council restricted to prevent a particular harm, an alternative condition is more persuasive where it addresses that same harm in a workable way.

This is where planning permission legal advice and specialist technical evidence may need to work together.

Do Not Simply Ignore a Difficult Condition

A condition does not disappear because it makes a development difficult to operate. If development proceeds in breach of a condition, the local planning authority may investigate and consider enforcement.

An informal council letter is different from a statutory notice. If a breach of condition notice is later served, it has a different challenge route from an enforcement notice and does not carry the same ordinary appeal to the Secretary of State. The campaign brief specifically requires this distinction.

Retrospective planning permission may sometimes be relevant where development has already departed from the permission, but it is not guaranteed and does not automatically stop enforcement.

Keep Other Property Controls Separate

Changing or removing a planning condition does not remove obligations under Building Regulations, licences, restrictive covenants, title restrictions or section 106 agreements. Those regimes operate separately.

A project may therefore become workable in planning terms while another legal or regulatory requirement remains. Aldwych Legal supports planning-dispute preparation, but separate property or regulatory issues may require their own analysis.

Conclusion

A planning condition can turn an otherwise acceptable permission into a scheme that is difficult or impossible to deliver. The first step is to understand why the condition was imposed and test it against the six national planning-condition requirements.

A direct section 78 appeal can challenge conditions attached to a permission, but it carries the risk that the whole planning application is re-determined. A section 73 application can offer a more focused route to varying or removing conditions, with a further appeal potentially available if that application is refused.

The strongest approach is to act early, use evidence that addresses the planning purpose of the condition and choose the route that best protects the wider development.

At a Glance

• Planning conditions can impose restrictions such as opening hours, technical requirements, and occupancy limits that may hinder the intended operation of a development.
• In England, the response to planning conditions depends on when they were imposed, whether development has started, and whether a challenge to the original permission or a later variation is sought.
• National guidance specifies that planning conditions must satisfy six tests: necessity, relevance, enforceability, precision, and reasonableness.
• Section 78 of the Town and Country Planning Act 1990 allows applicants to appeal objectionable conditions, but carries the risk of the Inspector reversing the entire planning permission.
• Section 73 enables modifications to existing planning conditions without reopening the entire application, resulting in a new independent planning permission.
• A refusal of a section 73 application can also be appealed to the Secretary of State, but new evidence is generally limited under the current appeal procedures.
