PLANNING APPEALS

When people hear the phrase “award of costs” during a planning appeal, it can sound intimidating — even a bit legalistic. But the concept is actually quite straightforward. This guide breaks down what an award of costs is, why it exists, and when it might be used.
1. What Is an Award of Costs?
In simple terms, an award of costs is a formal order saying that one party must repay another party’s wasted or unnecessary expenses from the appeal process.
This isn’t a fine, and it isn’t compensation for losing a planning application. Instead, it is a way of discouraging people from behaving unreasonably during an appeal — such as dragging out the process, failing to provide evidence, or pursuing an appeal that has no realistic chance of success.
An award of costs can cover expenses like:
Planning consultant fees
Time spent preparing appeal documents
Costs of attending a hearing or inquiry
Technical or specialist reports
Importantly, the order sets out the scope of what can be claimed, but it does not decide the exact amount of money owed. The amount is normally agreed privately between the parties afterwards.
2. Will I Have to Pay Costs Just Because I Lose an Appeal?
No.
Planning appeals are not like court cases where “the loser pays.” The default position is that everyone pays their own costs.
A costs award is only made where one party has caused another party to spend money unnecessarily because they behaved unreasonably. Losing an appeal, by itself, is not unreasonable.
It’s even possible for the “winning” party at appeal to have costs awarded against them if their behaviour caused unnecessary work for someone else.
3. Why Do Costs Awards Exist?
The costs regime is designed to:
Support a well-functioning planning appeal process
Encourage good behaviour and timely submissions
Deter people from pursuing hopeless or poorly prepared cases
Ensure councils also follow proper procedure and provide evidence
Once an appeal has been submitted, all parties fall under the costs rules — including appellants, councils, statutory consultees, and sometimes interested third parties.
4. When Can Costs Be Awarded?
For a costs award to be made, three tests must be met:
1. A timely application was made
Costs applications must be submitted within strict deadlines (more on this below).
2. A party behaved unreasonably
This can be on a procedural level (e.g., missing deadlines) or a substantive level (e.g., refusing an application for reasons that have no planning basis).
3. That behaviour caused unnecessary or wasted expense
There must be a clear connection between the unreasonable behaviour and the extra costs incurred.
If all three tests are satisfied, the inspector may award full or partial costs.
5. What Counts as “Unreasonable Behaviour”?
The bar for unreasonable behaviour is based on common-sense meanings, not a strict legal definition. It includes things like:
Examples for Local Planning Authorities
Refusing permission but not being able to justify the reasons at appeal
Ignoring relevant national or local policy
Failing to follow normal procedure or missing deadlines
Examples for Appellants
Pursuing an appeal with no reasonable chance of success
Submitting inadequate or inaccurate information
Withdrawing an appeal very late in the process
Examples for Any Party
Missing deadlines
Failing to engage in the process
Causing unnecessary delays
Introducing substantial new information at the last minute
This list isn’t exhaustive — the inspector looks at the specific circumstances of each case.
6. What Is “Unnecessary or Wasted Expense”?
To trigger a costs award, the unreasonable behaviour must lead to avoidable cost, such as:
Work that didn’t need to be done
Time spent responding to a reason for refusal that had no basis
Preparing for an appeal that should never have been necessary
Hiring experts because another party refused to provide key information
Costs must relate only to the appeal process, not the original planning application, and cannot cover things like economic loss or delays to building work.
7. Who Can Apply for an Award of Costs?
The appellant (usually the applicant or developer)
The local planning authority (LPA)
Interested parties who took part in the appeal (rare)
Statutory consultees in certain circumstances
The Mayor of London, in specific cases
Any party can have costs awarded against them, even if they applied for costs themselves.
8. Full vs Partial Awards
Full Award
Covers the applicant’s entire appeal-related costs.
Partial Award
Applies only to certain issues — for example:
One unreasonable reason for refusal
A period of delay
A particular part of the evidence
Most awards in practice are partial, because unreasonable behaviour often relates to only one aspect of the case.
9. When and How Should Costs Applications Be Made?
There are strict deadlines, depending on the type of appeal. For example:
At a hearing or inquiry: before the event closes
Written representations:
Householder/commercial/tree appeals: with the appeal submission
Other appeals: before the final comments stage
Issues arising from a site visit: within 7 days
Withdrawn appeals: within 4 weeks of notification
Late applications may be accepted, but the applicant must show good reason.
10. Can the Inspector Award Costs Even If Nobody Applies?
Yes — but this is rare.
Inspectors can initiate a costs award themselves if they see serious unreasonable behaviour that caused unnecessary cost, even if no one requested an award.
This power is used sparingly and follows a strict internal process to ensure fairness.
11. Does a Costs Application Affect the Appeal Decision?
Absolutely not.
Appeal decisions and cost decisions are treated as completely separate.
It is routine for inspectors to issue a planning decision and costs decision at the same time, but the two outcomes are independent.
12. Key Takeaways for Homeowners & Developers
A costs award does not punish losing — it punishes unreasonable behaviour.
Councils and appellants can both be at fault.
Most appeals proceed with no costs applications at all.
Full awards exist, but partial awards are more common.
Good preparation, timely submissions, and clear planning reasoning all help avoid costs issues.
