One of the first questions people ask after receiving a planning refusal is: “How long will the appeal take?”
The honest answer is that planning appeals in England and Wales follow a structured process, but the exact timeframe depends on the type of appeal, the complexity of the case, and the Planning Inspectorate’s workload.
That said, there are clear averages and expectations that can help you plan ahead.
Here’s a straightforward breakdown of typical appeal timescales.
Householder Appeals: 12–16 Weeks
Householder appeals — covering extensions, loft conversions, outbuildings, porches and other domestic works — are usually the quickest.
Typical timeline:
-
Validation: 1–3 weeks
-
Council response: 6 weeks
-
Inspector’s site visit: around week 10–12
-
Decision issued: usually by week 12–16
These appeals follow a simplified process, which is why they move faster than other types.
Full Planning Appeals: 4–6 Months
Appeals for new dwellings, conversions, commercial schemes, rural development and similar proposals take longer because they involve more evidence and a more detailed assessment.
Typical timeline:
-
Validation: 2–4 weeks
-
Council statement: 6 weeks
-
Final comments: 2 weeks
-
Site visit: around month 3–4
-
Decision: month 4–6
Complex cases or those involving multiple issues can take slightly longer.
Certificate of Lawfulness Appeals: 3–5 Months
LDC appeals rely heavily on evidence rather than planning judgement. The Inspector must assess legal tests, which can take time — especially if the evidence is extensive.
Typical timeline:
-
Validation: 2–4 weeks
-
Council statement: 6 weeks
-
Decision: month 3–5
These appeals can be quicker if the evidence is clear and uncontested.
Enforcement Notice Appeals: Highly Variable
Enforcement appeals have strict deadlines for submission, but the decision timeframe varies widely depending on:
-
the number of grounds of appeal
-
whether the Inspector requires a hearing or inquiry
-
the complexity of the alleged breach
Some enforcement appeals conclude in 4–6 months, while others — especially those involving legal arguments or multiple grounds — can take a year or more.
Why Do Appeals Take This Long?
Several factors influence the timeline:
1. The Planning Inspectorate’s workload
PINS handles thousands of appeals each year, and workloads fluctuate.
2. The need for fairness and due process
Councils must be given time to respond, and appellants must be given time to comment.
3. The Inspector’s site visit
This is a mandatory part of most appeals and must be scheduled around availability and weather conditions.
4. The complexity of the case
More evidence = more time needed for assessment.
Can Anything Speed Up the Process?
While you can’t fast‑track an appeal, you can avoid delays by ensuring:
-
all documents are complete and accurate
-
the appeal is professionally drafted
-
the correct national policy (NPPF or PPW) is used
-
the arguments are clear, structured and evidence‑led
A well‑prepared appeal is less likely to trigger requests for clarification — which can add weeks to the process.
Final Thought
Planning appeals take time, but they follow a clear and predictable structure. Whether your case is in England or Wales, the key to navigating the process smoothly is a strong, professionally prepared submission that addresses the refusal reasons directly and uses the correct policy framework.
If you’ve received a refusal and want to understand your likely timescales — and your chances — a professional review can give you clarity from the outset.
