Appealing a refused planning application in England: how to win

When you should appeal (and when you shouldn't)

Appeal when:

Don't appeal when:

• The council's refusal reasons are weak, contradictory, or don't reflect policy correctly
• Officer report contains factual errors or misapplied policy
• Similar schemes have been approved nearby and your refusal is inconsistent
• Refusal is based on non-material considerations or neighbor objections that aren't planning matters
• You have new evidence or policy interpretation that supports your case
• The refusal is a 'close call' and Inspector might take a different view
• Refusal reasons are clearly correct and policy-based (e.g., Green Belt inappropriate development with no exceptions)
• Multiple robust refusal reasons based on sound policy
• Design genuinely does cause substantial harm that can't be mitigated
• You can easily amend the design to address refusal reasons (resubmit instead)
• Council's decision is clearly in line with local plan and NPPF

The three types of planning appeals

You must choose an appeal procedure when lodging:

1. Written representations (most common): You, the council, and the Inspector exchange written statements. No hearing or site visit with parties present (though Inspector visits alone). Timeline: 12–16 weeks. Best for: Householder appeals, straightforward policy disputes, cases where facts aren't in serious dispute.

2. Hearing (semi-formal): Inspector holds a hearing session (like a round-table discussion) to explore issues. Everyone attends and participates. Timeline: 20+ weeks. Best for: Cases where clarification is needed, technical evidence to discuss, or moderate complexity.

3. Inquiry (formal): Most formal procedure with legal-style presentation, witnesses, cross-examination. Timeline: 26+ weeks. Best for: Major developments, highly contentious cases, technical expert evidence needed.

For most homeowners, written representations is the right choice—it's faster, less stressful, and success rates are similar to hearings for straightforward householder appeals.

How to lodge a planning appeal

Appeals are submitted online via the Planning Inspectorate's Appeals Casework Portal (https://acp.planninginspectorate.gov.uk/).

What you need to submit:

Deadlines: Householder appeals: 12 weeks from date of refusal decision. All other appeals: 6 months from refusal. Missing the deadline means you lose the right to appeal.

After lodging: The Planning Inspectorate validates your appeal, notifies the council, sets a timetable, and appoints an Inspector. The council submits their statement defending the refusal. You get a chance to respond to the council's statement. The Inspector visits the site. The Inspector issues their decision (allow or dismiss).

• Completed appeal form (online)
• Copy of the refusal decision notice
• Copy of your original application and all submitted documents
• Your grounds of appeal (written statement explaining why the council was wrong)
• Any new supporting documents or evidence

What the Planning Inspector assesses

The Inspector makes a fresh decision—they're not bound by the council's refusal, but they must consider:

The Inspector can: Allow the appeal unconditionally, allow with conditions, or dismiss the appeal. They explain their reasoning in a detailed decision letter (published publicly).

Inspectors are generally very thorough and policy-focused. Emotional arguments or personal circumstances carry little weight—policy compliance and planning merits matter.

• Whether the development accords with the development plan
• Material considerations (including the NPPF)
• The council's reasons for refusal and whether they're justified
• Your grounds of appeal and any new evidence
• Site context and impact (from their site visit)
• Relevant policy and appeal precedents

DIY appeals vs hiring a planning consultant

You can represent yourself in an appeal (DIY appeal) or hire a planning consultant/agent.

DIY appeal: Free professional costs, but you write all statements, respond to council's case, and represent yourself. Success rates for DIY householder appeals: around 25–30% (slightly lower than professionally represented appeals at 30–35%).

Hiring a consultant: Costs £2,000–£5,000 for written representation householder appeals, £5,000–£15,000+ for hearings or inquiries. Consultant writes appeal statement, responds to council's case, and represents you throughout.

When DIY makes sense: Simple householder appeal, clear policy error by council, you're confident in writing and policy interpretation.

When consultant is worth it: Complex policy issues, contentious application with strong objections, major development appeal, or you're not confident presenting your case.

Common mistakes that lose appeals

These mistakes sink appeals:

• Missing the appeal deadline—householder appeals must be lodged within 12 weeks of refusal
• Emotional arguments rather than policy-based grounds—Inspectors assess planning merits, not personal circumstances
• Not responding to the council's statement—if you don't rebut their case, it stands unchallenged
• Introducing major design changes during appeal—Inspectors can't consider substantially different schemes
• Weak grounds of appeal that don't address the refusal reasons—you must specifically counter each refusal reason
• Appealing when the council is clearly right—wastes 12+ weeks when you should be amending and resubmitting

Real costs and timelines

Appeal costs if DIY: £0 (your time only). Timeline: 12–16 weeks (written reps), 20+ weeks (hearing), 26+ weeks (inquiry).

Appeal costs if hiring consultant: £2,000–£5,000 (written reps householder), £5,000–£12,000 (hearing), £10,000–£25,000+ (inquiry for major schemes). Add expert witness fees if needed (£1,500–£5,000+ per expert).

Success rates: Householder appeals: 30–35% allowed. Minor commercial/residential: 30–40% allowed. Major developments: 30–35% allowed. Green Belt appeals: 10–20% allowed (much lower due to strong policy protection).

Cost if you lose appeal: Time and professional fees are lost. You can resubmit amended plans (full fee again) or abandon project.
