How to appeal a planning rejection UK 2026

Your local council has refused planning permission for your home extension, loft conversion, or solar array. The refusal notice lists reasons that seem unfair or misapplied. You need to know whether an appeal is worth the time and money.

The direct answer is that you submit a written-representation appeal to the Planning Inspectorate within 12 weeks of the refusal, costing nothing in fees, and you have roughly a one-in-four chance of winning. This article explains the three appeal routes, the documents you must prepare, and what happens after the inspector decides.

The average homeowner wins one in four planning appeals — here is what that costs and how long it takes

In 2025–26, 26% of householder appeals in England were allowed, meaning the original refusal was overturned or conditions were varied (GOV.UK, Planning Inspectorate appeal statistics, 2026 release). A further 7% were partly allowed or varied. The remaining two-thirds were dismissed.

The median processing time for a written-representation appeal is 14 weeks from submission to decision (Planning Inspectorate quarterly performance data, Q1 2026). The appeal fee for a householder development is £293, but only if you choose the full hearing or public inquiry route. Written-representation appeals are free to submit.

Your chances improve if you address the specific policy grounds in the refusal notice. Appeals dismissed on design grounds, for example, succeed less often than those dismissed on procedural or technical errors.

Quick numbers the three appeal routes compared by time, cost, and success rate

Data sourced from the Planning Inspectorate annual report 2025–26 (DESNZ / MHCLG, 2026). Success rates vary by region and case complexity. The written-representation route accounts for over 80% of all householder appeals because it is free and does not require a public appearance.

The first step check whether your rejection is appealable at all

You can only appeal if the local planning authority (LPA) refused permission, granted it with conditions you cannot accept, or did not decide within eight weeks (GOV.UK, Appeal a planning decision, 2026). Non-determination appeals require the LPA to have missed the statutory eight-week deadline — check the decision date on your refusal notice.

Some refusals cannot be appealed. For example, if your project falls under permitted development rights and the LPA issued a prior approval refusal, you must re-apply or seek a lawful development certificate instead. Similarly, refusals for advertisement consent or tree preservation orders follow separate routes under the Town and Country Planning Act 1990, Section 78, as amended (legislation.gov.uk, 2026).

The direct answer you appeal by submitting form APP/201 to the Planning Inspectorate within 12 weeks

Householder appeals must be lodged within 12 weeks of the refusal date. For major developments, the deadline is six months. Mark the calendar immediately — missing the deadline means you lose the right to appeal (GOV.UK, Form APP/201, 2026).

Submit online via the Planning Portal or by post. You must include the original application reference, the refusal notice, and your grounds of appeal. The written-representation route is the default — you send a statement and supporting documents, the LPA responds, and an inspector decides on paper without a hearing (Planning Inspectorate, How to appeal: Householder applications, 2026).

If you choose the informal hearing or public inquiry route, you must pay the £293 fee and attend a meeting where you can present your case in person. The inspector will decide which route is appropriate based on the complexity of the issues.

What you must include in your appeal statement to give yourself a realistic chance

State clearly why the LPA’s reasons for refusal are wrong. Cite the relevant local plan policy or the National Planning Policy Framework (NPPF) paragraph from the 2026 revision (MHCLG, 2026). For example, if the LPA refused on design grounds, show how your proposal meets the NPPF’s design objectives or the local design guide.

Provide photographic evidence, site plans, and any neighbour letters of support that counter the LPA’s objections. If the refusal cited loss of light, include a daylight/sunlight study prepared by a surveyor. For heritage-related refusals, a heritage impact assessment is essential (Planning Inspectorate, Guidance on written representation appeals, 2026).

Keep your statement concise — typically two to three pages. The inspector reads hundreds of cases. Clear, policy-based arguments carry more weight than emotional pleas. how to write a planning statement that wins

Eligibility and certification who can submit an appeal and what paperwork you need

Any person with an interest in the land — owner, tenant, or their agent — can appeal. You do not need a solicitor or planning consultant, though professional advice can improve your chances on complex cases (GOV.UK, Appeal a planning decision checklist, 2026).

You must upload the original planning application forms, the decision notice, and any correspondence with the LPA. If you used an agent to submit the original application, you must provide written authorisation from the landowner confirming they can act on your behalf (Planning Inspectorate, Who can appeal, 2026).

No formal certification or accreditation is required. The process is designed to be accessible to homeowners without legal training.

What happens after you submit — the inspector’s decision and your options if you lose

The inspector will issue a written decision with reasons. They can allow the appeal (grant permission), dismiss it, or vary the conditions. If allowed, the permission is treated as if the LPA had granted it originally (Planning Inspectorate, After an appeal, 2026).

If dismissed, you cannot appeal the inspector’s decision to a higher body. The only recourse is judicial review on a point of law, which must be lodged within six weeks. Judicial review is expensive (typically £5,000–£15,000 in legal costs) and rarely succeeds for householder appeals (GOV.UK, Judicial review guidance, 2026).

A more practical option is to revise your proposal and submit a fresh planning application to the LPA. If you re-submit a similar scheme within 12 months of the original refusal, the LPA waives the application fee. This route often succeeds because you can address the council’s specific concerns without the adversarial tone of an appeal.
