Appeal timetables and the six month deadline
Appeal deadlines run from the date on the decision notice and the appeal must arrive complete. Here is the period for each appeal type and how to use the window rather than sit in it.
You have six months to appeal most refusals and twelve weeks to appeal a householder refusal. The clock runs from the date on the decision notice, not the date it landed on your doormat, and the appeal has to reach the Planning Inspectorate inside the period rather than merely be posted inside it. Those three sentences account for most missed appeals.
Enforcement notices are stricter again. The appeal must be received before the date the notice takes effect, and there is no discretion to accept a late one.
The deadline for each appeal type
The periods differ by what was refused, and they are not intuitive.
| Decision appealed | Period to lodge |
|---|---|
| Refusal of full or outline permission | Six months from the date of the decision notice |
| Refusal of householder permission | Twelve weeks from the date of the decision notice |
| Refusal of minor commercial permission | Twelve weeks from the date of the decision notice |
| Refusal of advertisement consent | Eight weeks from the date of the decision notice |
| Refusal of listed building or conservation area consent | Six months from the date of the decision notice |
| Refusal of a lawful development certificate | Six months from the date of the decision notice |
| Non-determination | Six months from the end of the determination period |
| Enforcement notice | Before the date the notice takes effect |
Check the current position on the appeal service before relying on any table, including this one, because the periods have been changed by legislation more than once.
How the period is counted
From the date on the decision notice. Not the date of the committee meeting, not the date of the email, not the date you opened it.
A six month period ending on a weekend or bank holiday still ends on that day. The appeal is made when the Inspectorate receives a valid appeal, which in practice means a complete submission through the appeals service. An incomplete appeal submitted on the last day is not an appeal, and the Inspectorate will return it.
That is the argument for lodging a fortnight early. The Inspectorate checks validity, and a missing ownership certificate or an unlisted document turns into a request for information that you no longer have time to answer.
Shorter windows for householder appeals
The twelve week householder deadline exists because the procedure is expedited. It runs on written representations only, with a simplified form and a tighter timetable.
The trade-off is that the case you submit is the case you get. Householder appeals do not allow further representations after the appeal is made, so the appeal statement has to be complete on the day you lodge it. Nothing can be added when you see what the council says.
Write the statement as if the inspector will read only it and the officer's report. Be specific about what changed since the refusal, if anything did, because an inspector determining a householder appeal is looking at the same scheme the council saw. Address each reason for refusal in order, by its own number, and attach the drawings at a size the inspector can read on a site visit in the rain.
Enforcement notice appeals
These deserve their own paragraph because the consequences are different.
An enforcement notice specifies a date on which it takes effect, normally at least 28 days after service. An appeal must be received before that date. If it is not, the notice takes effect, the alleged breach becomes an offence to continue, and the right to challenge the planning merits is gone.
There is no extension, no discretion and no late acceptance. Where an enforcement notice arrives, take advice the same week. The grounds of appeal are specific and pleading the wrong ones can be fatal, and a ground that was available and not pleaded cannot usually be raised later.
What cannot be extended, and the narrow exception
For section 78 appeals there is a discretion to accept an appeal made outside the period, but it is exercised rarely and should never be part of a plan. The circumstances that succeed tend to involve something outside the appellant's control and evidenced, not an oversight.
There is no equivalent discretion for enforcement appeals.
One practical trap sits inside the discretion. Asking the Inspectorate whether it will accept a late appeal takes time, and the answer usually arrives after every other option has closed.
Assume the deadline is absolute. Diary it on the day the decision arrives, diary a reminder six weeks before it, and treat the earlier date as the real one.
Using the window rather than sitting in it
Six months sounds generous. It is not, if the reason for refusal needs evidence that has a season attached to it.
A refusal citing inadequate ecological information may need a survey that can only be done in a specific window. A newt survey, a botanical survey or a bat emergence survey missed in May cannot be conjured in November, and our note on water vole survey season and watercourse works shows how narrow some of those windows are. Similarly, a refusal on parking evidence may need a survey conducted under the recognised methodology in a neutral period, which our guide to parking survey timing sets out.
Where the missing evidence cannot be obtained inside the appeal window, a fresh application is often the better route. It also avoids appealing on an incomplete case, which risks a dismissal that makes the next application harder.
Use the first fortnight to get the officer's report, read every consultee response, and work out whether the refusal is about principle or about evidence. Refusals about evidence are usually better fixed than argued.
The officer's report is the most useful document in the file and the one applicants read last. It sets out how the authority weighed each policy, which consultee objections carried weight and which were discounted, and it usually reveals whether the case turned on one issue or several. An appeal statement written without it is an appeal statement written blind.
The alternative to appealing
A revised application addressing the reasons for refusal is frequently quicker, costs less and is more likely to succeed than an appeal, particularly for householder schemes where the objection is to a detail rather than to the principle.
The fee regulations have historically allowed one further application on the same site within a period after a refusal without a further fee, subject to conditions. Check the current fee schedule before relying on it, because the regulations are amended and the position on repeat applications has been under review.
Either way, the document that carries the argument is the Planning Statement, setting out the policy case reason by reason. Draft it against the refusal notice rather than against the original scheme.
This is general guidance, not legal advice. Check the position with your local planning authority or a qualified professional before relying on it.

Frequently asked questions
When does the appeal period start?
On the date printed on the decision notice, not the date you received it or the date the committee met. The appeal must reach the Planning Inspectorate as a valid, complete submission within the period. An incomplete appeal lodged on the final day will be returned, so treat a date around two weeks before the deadline as the real one.
Why is the householder appeal deadline shorter?
Because the procedure is expedited. Householder appeals run on written representations with a simplified form and a compressed timetable, which is why the period is twelve weeks rather than six months. The trade-off is that no further representations are allowed after the appeal is made, so the statement you lodge has to be complete on the day.
Can a late planning appeal ever be accepted?
For section 78 appeals there is a discretion to accept an appeal outside the period, but it is exercised rarely and generally requires evidenced circumstances outside the appellant's control. It should never form part of a plan. For enforcement notice appeals there is no discretion at all, and a late appeal simply cannot be entertained.
What happens if I miss an enforcement notice appeal deadline?
The notice takes effect, the planning merits can no longer be challenged through the appeal, and continuing the breach after the compliance period becomes a criminal offence. Enforcement notices specify the effective date on their face, usually at least 28 days after service. Take advice the week the notice arrives rather than waiting to see what happens.
Should I appeal or submit a revised application?
Where the refusal turns on a detail rather than the principle, a revised application is often faster and more likely to succeed. It is also the better route where the missing evidence depends on a survey season falling outside the appeal window. Check the current fee regulations for the position on further applications before assuming a resubmission carries no fee.
