Proving the date a planning application was received
The determination period runs from the day after a valid application is received, not from the day it arrived. Here is the evidence that settles the argument.
Two dates sit on every planning application and only one of them matters for the statutory clock. The date received is the day the submission reached the authority. The validation date is the day the authority accepted it as a valid application, and the determination period runs from the day after that. When a council tells you the eight weeks started three weeks later than you thought, the argument is almost always about what was missing on the day of receipt, and the evidence you need to win it is evidence you can only gather at the point of submission.
Why the receipt date matters
The determination period set by the Town and Country Planning (Development Management Procedure) (England) Order 2015 begins the day after a valid application is received: eight weeks for most minor applications, thirteen for a major, sixteen where the development is subject to environmental impact assessment.
Everything downstream hangs off it. The expiry date governs whether you can appeal against non-determination. It governs whether an extension of time needs agreeing in writing. On a scheme with a funding deadline or an option expiry, three weeks of drift is the difference between a deal and no deal.
The validation date is also the date from which the authority's performance is measured, which gives planning support teams a reason to validate carefully rather than generously.
Received against valid
An application is received when it arrives. It becomes valid when the authority holds everything the national requirements and its own published local list demand: the completed forms, the ownership certificate, the location plan and site plan at recognised scales, the drawings, any design and access statement that is required, the local list documents, and the fee.
Miss one item and the application sits in a holding state. The council will usually write and ask for it, and the clock starts when it arrives rather than when the rest of the submission did.
| Event | What it fixes |
|---|---|
| Date received | The date on the council's record of arrival, and the reference number |
| Date fee received | Validity cannot be achieved before this |
| Validation date | The day before the determination period begins |
| Expiry of determination period | The earliest date for a non-determination appeal |
One point worth knowing about local lists. A local requirement cannot be relied on unless the authority published it within the two years before the application was made. Where a council refuses to validate because of a document that appears only on a list last reviewed five years ago, say so, politely, in writing, and ask them to identify the publication date they are relying on.
Evidence to keep from an electronic submission
Gather this at the moment of submission. Reconstructing it a month later is unpleasant and sometimes impossible.
- The submission confirmation email, with its date, time and submission reference, saved as a file rather than left in a mailbox.
- The payment receipt or transaction reference for the fee, with the date and the amount.
- A copy of the submitted document set exactly as it went, with file names and revision numbers.
- A schedule of documents submitted, cross-referenced to the national requirements and to each item on the council's local list.
- Screenshots of the submission summary page if the system shows one.
Where you submit by email because the portal is down or the application type is unusual, send it to the address the council publishes for applications, ask for an acknowledgement, and follow up within two working days if none arrives. Where you submit on paper, use a service that records delivery.
And keep the fee evidence separate from everything else, because that is the item most often disputed. A short note on fee exemptions and reductions should be read first, since a claimed exemption that the council rejects is itself a reason an application fails to validate.
When the submission system fails
Electronic submission failures happen, usually at the point of payment or on a large upload. The useful response is to document the failure as it occurs: the error message, the time, the browser or client, and what you did next.
If the submission was made before midnight and the council's system logged it the following morning, the date on the acknowledgement may differ from the date you submitted. For most applications that is a day and nobody cares. Where a policy change, a fee uplift or a plan adoption falls between the two dates, it can matter considerably, and the confirmation email with its timestamp is the only thing that will settle it.
Disputing a validation date
There is no statutory appeal against a refusal to validate, which shapes the whole approach. What you have instead is correspondence, escalation and, at the far end, judicial review or a non-determination appeal based on your own asserted date.
Work through it in order.
Ask the planning support team, in writing, to identify precisely which national requirement or local list item they regard as missing, and where that local requirement was published. Then either supply it or explain why it does not apply to this application. Where the item is one a council commonly asks for and rarely needs, a short paragraph in the covering submission explaining why it is not relevant to this proposal often resolves it without an argument.
If that fails, escalate to the development management team leader rather than repeating the exchange. Keep it factual: the submission date, the document schedule, the requirement in dispute, and the publication date of the local list.
Appealing against non-determination from your own asserted validation date is available, and it is a calculated risk, because the Planning Inspectorate will decide whether the appeal is valid and may conclude the period had not expired. Our note on appealing non-determination or waiting sets out when that gamble is worth taking.
Effect on the appeal clock
Appeal deadlines run from decisions, not from validation, but validation still reaches them.
A refusal gives six months from the date of the decision notice to appeal, or twelve weeks for a householder or minor commercial appeal. Non-determination gives six months from the expiry of the determination period, which is the date you have been arguing about. So a validation date pushed back by three weeks pushes the non-determination appeal window back with it.
Where an extension of time has been agreed, the agreed date replaces the statutory expiry for these purposes, which is a good reason to agree extensions in writing and to keep the email.
Practice that removes the argument
The reliable fix is to make validation boring.
Download the authority's published local list on the day you submit and save the file with its date. Build your document schedule against it, item by item, and submit the schedule as part of the application. Pay the fee with the submission rather than afterwards. Then send one short email to the planning support team confirming the submission reference and asking them to confirm the validation date once registered.
As an illustrative example, an architect submitting a 14 unit scheme might send a one page schedule listing 23 documents against the 11 national and 9 local requirements, with a line against each, and two notes explaining why a transport assessment and an archaeological assessment are not engaged at this scale. Validation on that application is a tick box exercise. The same submission without the schedule invites a holding letter.
A Planning Statement can carry that schedule as an appendix, and on a larger scheme it is the natural home for it. For anything beyond a householder application, work out the document set before you draw, not after, and browse the report types by category if you are unsure which are engaged.

Frequently asked questions
When does the eight week determination period start?
The day after a valid application is received, which is the validation date rather than the date the submission arrived. Eight weeks applies to most minor applications, thirteen to a major application and sixteen where environmental impact assessment applies. An agreed extension of time replaces the statutory expiry date.
Can a council refuse to validate for a local list item?
Yes, but only where the local requirement was published within the two years before the application was made. If a council relies on a list that has not been reviewed within that period, ask it in writing to identify the publication date it is relying on before you supply the document.
What evidence should I keep when submitting electronically?
The submission confirmation email saved as a file, the fee payment receipt with its transaction reference, the document set exactly as submitted with file names and revisions, a schedule mapping documents to the national and local requirements, and a screenshot of any submission summary page the system displays.
Is there an appeal against a refusal to validate?
No statutory appeal exists. The options are correspondence and escalation within the authority, judicial review, or a non-determination appeal based on your own asserted validation date. The last of those is a calculated risk, because the Planning Inspectorate may conclude the determination period had not expired.
Does the validation date affect the appeal deadline?
For a refusal, no, because the deadline runs from the decision notice: six months generally, or twelve weeks for a householder appeal. For non-determination it matters directly, because the six month window runs from the expiry of the determination period, which depends on the validation date.
