A planning appeal in the UK is a formal process that allows you to challenge a planning refusal by a local Council. Appeals are submitted to the Planning Inspectorate, which independently reviews whether the Council made the correct decision based on planning policy and material considerations.

To appeal a planning refusal, you must submit your appeal within the legal time limit, usually 6 months from the date of the decision notice. The appeal must include the original application, the Council’s decision notice, and supporting evidence explaining why the refusal should be overturned.

The main steps in a planning appeal are:
- Reviewing the Council’s reasons for refusal (We offer a free review on the decision notice and give our thoughts on the best way forward and chances of success).
- Research the planning history of the site and the neighbouring area. 
- Compile a robust argument and planning statement detailing in planning terms the strengths of the proposal as to why the planning department should allow the scheme. Submit the planning appeal and all relevant supporting documents to the Planning Inspectorate.  
- Liaise with the Council's planning officer throughout the process to update and respond to requests for further information.
- A final decision notice issued by an independent Planning Inspector.  

There are three types of planning appeal: written representations, hearings, and public inquiries. Most appeals are decided through written representations.

A planning appeal is determined strictly on planning policy and material considerations, not public opinion. Success at appeal depends on whether the proposal complies with relevant local and national planning policies and whether a clear, well-evidenced case is presented to justify overturning the refusal.

Get in touch with us (either via the form on our website, phone or email), and we will identify the reason or reasons for refusal and evaluate if you have grounds for appeal.

There are a few variations of planning appeal, and the type of appeal we recommend will relate to the kind of planning application that was made - The most common being a written representation appeal. A not-often-known fact is that a planning appeal can also be made against any part of the conditions imposed on the planning permission.

●      Written representations
●      Hearings
●      Public inquiries

This is the fastest and often cheapest way to appeal a planning decision. The Planning Inspectorate (an independent Government body) looks at the submitted planning appeal and makes an independent decision outside of the Council's influence or pressure.

This method is suited to smaller-scale development such as house extensions, changes of use or appeals against planning conditions. This appeal procedure has been used as the ‘fast track’ householder appeal service since January 2008.

Cost awards are available for all written representation appeals.

Hearings take longer than written representation, but they allow all parties to present their case informally to an inspector, who leads a discussion on the appeal issues.

Hearings are suited to more complicated cases that require detailed discussion about the merits of the proposal.

Again, cost awards are possible for planning appeals dealt with by a hearing.

The most formal method of planning appeal is by Public inquiry. These are used for larger, more complex cases and can take several months because the inspector hears evidence from witnesses, often cross-examined by other parties’ legal representatives.

Public inquiries are suited to more controversial cases where there has been a lot of public opposition.

Cost awards can be available for any appeal.

The most important element of any planning appeal will be the Supporting Planning Statement. Our statements are never AI-generated or a template from past cases, but deal with the key issues of your case, addressing their relevant policies (both national & local) and setting out the planning grounds in favour of your proposal, whilst also addressing any tricky points that a case may present. This level of detail is often the area that wins us the appeal and sets us apart from other planning consultants.

A planning appeal in the UK typically takes between 4 and 12 months, depending on the appeal type and the complexity of the case.

The most common appeal is a written representation appeal, which usually takes around 4 to 8 months, making it the fastest appeal route. Informal hearings generally take 6 to 9 months, while public inquiries can take 9 to 12 months or longer in more complex cases.

The timescale for a planning appeal depends on:
- The type of appeal procedure used 
- The complexity of the planning issues involved 
- The workload of the Planning Inspectorate 
- Whether additional evidence or statements are required 

Once an appeal is submitted, the Planning Inspectorate sets a timetable for the submission of evidence and statements before a final decision is issued.

Our team can help you understand the full planning appeal timeline from start to finish and work to keep the process moving as efficiently as possible, often able to speak directly with the case officer.

There are no charges by the Planning Inspectorate to submit a planning appeal. Our fees are decided on a case-by-case basis and will be included in our free proposal. Planning appeal costs will depend on the type and complexity of the appeal, the volume of supporting material needed, and whether a hearing or public inquiry is required. We offer clear, competitive pricing with no hidden fees, so you have full visibility from the outset.

The chances of winning a planning appeal depend on the planning merits of the case, including compliance with planning policy, the strength of evidence, and the reasons for refusal. There is no fixed success rate, as each case is decided individually by an independent Planning Inspector.

A planning appeal is more likely to succeed where a strong argument is made that the proposal complies with local development plan policies and national planning guidance, and/or where the Council’s refusal reasons are weak, unsupported, or incorrect in planning terms.

A planning appeal is less likely to succeed where the development causes significant planning harm that is not outweighed by benefits, or where it clearly conflicts with adopted planning policy.

Key factors that affect success include:
- Demonstrate compliance with local and national planning policy 
- Strength and clarity of planning justification 
- Quality of supporting evidence and reports 
- Design quality and impact on the surrounding area 
- Challenging the accuracy of the Council’s decision-making process 

Planning Inspectors make decisions independently based on planning law and policy rather than public opinion or weak local objections.

As every case is different, we will always give an honest view of the chances of success and suggest the best way forward. As we offer a unique partnership whereby Senior Town Planners who currently work within local Councils work on your case, we are able to anticipate common or uncommon reasons for refusal and tailor your appeal strategy accordingly.

Understanding how to win a planning appeal requires an in-depth knowledge of the planning appeal process, policy interpretation and persuasive presentation. Our transparent advice ensures you know where you stand from day one.

Understanding why planning permission is rejected is key to building a strong case. Common reasons include design issues, overlooking policies, highway concerns, and failure to meet local development frameworks.

If your planning permission has been refused, our team can analyse the decision, identify weak points, and build a robust appeal.

The Planning Inspectorate has introduced a simpler process for all planning appeals. The main change is the "Submit Once, Submit Right" rule. This means most appeals are now handled quickly through a standard process called Part 1 Written Representations. Under these new rules, planning decisions are based only on the information and evidence you provided with your original application, giving you very little chance to add new evidence or fix mistakes later.

No. Under the new rules, the Planning Inspectorate will very rarely accept new reports, evidence, or design changes during the appeal unless they fall under a very limited number of exceptions. Since you can no longer use an appeal to fix problems with your initial application, it's very important to make sure your original submission or appeal form is complete and strong from the start, then AFA Planning Consultants can support you in finding an exception for you to submit any new evidence under.

To win a planning appeal, you need to show that your proposal fully meets local planning rules or that the Council’s reasons for refusing are legally or factually wrong. Since success depends on planning laws and policies rather than opinion, having a detailed, policy-based argument written by experienced planning consultants is the best way to overturn a refusal.

If the Planning Inspectorate refuses your appeal, the original decision to refuse permission remains in place. Your options then are to significantly alter your plans and submit a new application, or, if you believe there was a legal mistake in the decision, challenge it through a Judicial Review in the High Court within 6 weeks.
