A refusal isn't the end of the road, but it isn't nothing either. Appealing a planning decision costs time, costs money, and - here's the uncomfortable bit most guides skip over - most appeals still fail. So before you fire off a Planning Inspectorate form in a fit of righteous indignation, the real first question isn't "how do I appeal?" It's "should I?"
This guide covers both. We'll walk through the planning appeals process from start to finish, then get into the part that actually matters most: how to judge your odds and build a case that gives you a genuine shot at winning, rather than just a longer, pricier route to the same "no."
Key Highlights
- Only the original applicant can appeal a planning refusal - there's no third-party right of appeal in England.
- Roughly a third of planning appeals succeed, so it's worth weighing your odds before committing time and money.
- There are three appeal routes: written representations (most common), hearings, and public inquiries.
- You have 12 weeks to appeal a householder refusal, and 6 months for most other applications and conditions.
- Written representations typically take 12 to 26 weeks to resolve; hearings and inquiries take longer.
- Appeals are free to lodge, though most applicants use a planning consultant, and costs can occasionally be awarded against either party.
- Comparable appeal decisions nearby are some of the strongest evidence you can bring - and the easiest to overlook.
- LandInsight helps you check planning history and appeal outcomes on similar sites, so you can judge your chances before you commit.
When Can You Appeal, and Should You?
Not everyone gets to appeal a planning decision, and not every refusal is worth appealing. Let's deal with both.
Who can appeal. Only the person or company who submitted the original application can lodge a planning appeal. If you're a neighbour who disagrees with a decision, or a third party objecting to someone else's approval, there's no right of appeal in England, however strongly you might feel about it. That route runs through judicial review instead, which is a different (and much narrower) legal process entirely.
What you can appeal. There are three main grounds:
- Refusal - your application was turned down outright.
- Conditions - your application was approved, but with conditions you consider unreasonable or unworkable.
- Non-determination - the council simply didn't decide within the statutory timeframe, so you're appealing the silence rather than a decision.
Should you appeal, though? Here's the honest picture: roughly a third of planning appeals in England are allowed. That means two out of three fail. It's not a coin toss stacked in your favour, and it's worth a good think before you commit months and a fair amount of budget to the process.
Appealing a planning decision tends to make sense when the refusal reasons are genuinely arguable - where you believe the council has misapplied policy, misread the evidence, or reached a conclusion that similar cases nearby haven't. It makes much less sense when the refusal reasons are fixable. If the issue is a design tweak, a reduced unit count, or an amended access arrangement, amending and resubmitting is often faster, cheaper, and considerably less stressful than waiting six months for an inspector's decision on a case you could have simply improved.
The sections below cover how to run that process well, and - because this is where most guides stop short - how to actually judge whether your case is strong enough to be worth the fight.
The Planning Appeal Process, Step By Step
Once you've decided to go ahead, the planning appeal process follows a fairly structured procedure, and it's more approachable than it first looks. Here's how it works.
1. Choose your route
There are three ways an appeal can be handled:
- Written representations - the most common route by some distance. You and the council each submit written evidence, and the Planning Inspectorate makes a decision based on the papers alone, usually with a site visit.
- Hearing - a more informal, round-the-table discussion led by an inspector, useful when there are points that benefit from being talked through rather than argued on paper.
- Inquiry - the most formal route, resembling a courtroom process with witnesses, cross-examination, and legal representation. Reserved for complex or high-stakes cases.
Which route you get depends on the complexity of the case and, for larger schemes, which route you request.
2. Check your deadline
This is the one part of the process with zero flexibility:
- 12 weeks from the decision date for householder applications.
- 6 months from the decision date for most other applications, including conditions and non-determination appeals.
Miss the window and that's it - there's no late submission, no appeal against the deadline itself.
3. Submit your appeal
Planning appeals in England are submitted directly to the Planning Inspectorate via the GOV.UK appeals service. You'll need your original application, the refusal notice (or evidence of non-determination), your grounds for appeal, and any supporting evidence such as planning statements, expert reports, or precedent cases.
4. The council responds
The local authority submits its own statement defending the original decision, and interested parties (neighbours, parish councils, and so on) can submit comments too.
5. The inspector decides
For written representations, this happens on the papers plus a site visit. For hearings and inquiries, there's a scheduled session before the decision is issued.
Sound bureaucratic? It is, a bit. But it's a well-worn process, and knowing exactly which route and deadline applies to you removes most of the anxiety early on.
Timelines and Costs
Two questions come up constantly with planning appeals: how long will this take, and what will it cost me?
Timelines vary by route. Written representations, the route most applicants end up on, typically take somewhere between 12 and 26 weeks from submission to decision. Hearings generally run a little longer once you factor in scheduling, and inquiries - given their complexity - can take considerably longer still, sometimes stretching well beyond a year for the largest or most contested schemes.
We've written a full data-driven breakdown of what actually determines how long a planning appeal takes, based on real appeal data rather than headline averages, in our guide to planning appeal timescales - well worth a read if timing is your main concern, since it's the more detailed home for that data.
Costs are more straightforward at the headline level: lodging a planning appeal itself is free. The Planning Inspectorate doesn't charge a fee to submit one. Where costs come in is everything around the appeal - most applicants for anything beyond a straightforward householder case bring in a planning consultant or agent, and fees vary widely depending on complexity, evidence requirements, and whether you're heading to a hearing or inquiry rather than written representations.
There's also the possibility of a formal award of costs, where one party (either the applicant or the council) is ordered to cover the other's costs if they're found to have behaved unreasonably during the process - for example, if a council fails to properly justify its refusal reasons. It's the exception rather than the rule, but worth knowing about.
How to Build a Stronger Appeal
This is the part most planning appeal guides skim past, and it's arguably the most useful section in this one.
Start with the refusal reasons, not your frustration. Read them line by line and test each one against the relevant policy - national policy in the NPPF, and local policy in the council's local plan. Our guides to the NPPF and to reading a local plan are useful starting points if you want a policy refresher before you draft your grounds.
Use comparable appeal decisions as evidence. This is the single most underused tactic in a planning appeal, and it's also where most applicants leave value on the table. Inspectors are influenced by precedent. If a similar site nearby, facing a similar objection, was allowed on appeal, that's genuinely persuasive evidence that your case sits within what's considered acceptable. Equally, understanding why comparable appeals were dismissed can help you shore up weak points in your own case before an inspector finds them for you.
The trouble is that finding those comparable appeals has traditionally meant trawling the Planning Inspectorate's database site by site, which is slow, fiddly, and easy to get wrong if you don't know exactly what you're searching for.
This is exactly where LandInsight earns its keep. It surfaces planning history and appeal outcomes for sites near yours, so you can see how similar cases were judged, what evidence and arguments succeeded, and where they fell down. Rather than guessing at your odds, you can look at the actual precedent on your doorstep and build your case around it.
See how similar appeals were decided nearby with LandInsight - it's a genuinely practical way to judge your chances and cite precedent before you commit to the process.
FAQs
-
How long does a planning appeal take?
It depends on the route. Written representations usually take 12 to 26 weeks; hearings and inquiries take longer. For a full breakdown of what actually drives appeal timescales, see our data-story on planning appeal timelines.
-
How much does a planning appeal cost?
Lodging an appeal is free. The real cost comes from professional fees if you bring in a planning consultant or agent, which varies depending on complexity and the route your appeal takes.
-
What are my chances of winning a planning appeal?
Roughly a third of planning appeals in England are allowed. Your odds improve considerably if your grounds are well evidenced and supported by comparable appeal decisions nearby.
-
Can I appeal if the council did not decide in time?
Yes. This is called a non-determination appeal, and it follows the same process as appealing an outright refusal, using the same 6-month deadline for most application types.
-
What is the difference between an appeal and a judicial review?
A planning appeal challenges the planning merits of a decision and is only available to the original applicant. A judicial review challenges whether a decision was made lawfully and correctly (rather than whether it was the "right" call), and it can be brought by third parties, including objectors, within a much tighter timeframe.
Ready to Judge Your Odds?
Most planning appeals fail, so the ones worth pursuing are the ones where the evidence is genuinely on your side. LandInsight shows you how comparable appeals were decided nearby, so you can weigh your chances honestly before you commit the time and budget to finding out the hard way.
