When a council refuses to validate your application
An unvalidated application does not exist and no clock is running. Separating national information requirements from local list items is the first step in any validation dispute.
An application that is not validated does not exist. The eight week clock has not started, the application does not appear on the register, and no consultee has been asked anything. When a council refuses to validate your application the first job is to work out whether the missing item is a national requirement, which is not arguable, or a local list requirement, which is.
What validation is and who decides it
Validation is an administrative check, carried out by a support team rather than by the case officer, against a defined list. The Development Management Procedure Order 2015 sets the national information requirements, and it allows authorities to publish a local list of additional information they require.
Two conditions attach to the local list. The requirement must have been published, and the publication must be reasonably current, since the Order limits how long a local requirement can be relied on without being reviewed. And the requirement must be reasonable having regard to the nature and scale of the development, and must relate to a matter it is reasonable to think will be a material consideration.
Those two conditions are the whole of your argument when a request is unreasonable. A validation officer asking for a transport assessment on a two-storey rear extension is not applying the local list, they are applying a checklist without judgement.
National requirements are not negotiable
Deal with these first, because disputes about them waste everybody's time.
The application form, completed. The correct certificate of ownership, with the agricultural holdings declaration where relevant, and notice served on any other owner. A location plan identifying the land, at a standard scale with the site outlined. The plans and drawings necessary to describe the development. The correct fee. A Design and Access Statement where the development is one for which the Order requires it.
Certificates are the commonest failure. An applicant who owns part of the access strip and signs certificate A, rather than serving notice and signing certificate B, has made the application invalid and, worse, has signed a certificate that is wrong.
Fee errors are the second. The fee regulations are amended regularly and are indexed, so use the council's current fee calculator rather than a figure from a previous project. An underpayment of a few pounds invalidates the application as effectively as a missing certificate, and nobody will telephone to tell you.
Common reasons applications are rejected
Beyond certificates and fees, the same items recur.
- Drawings without a scale bar, a north point or a drawing number, or submitted at a scale the stated ratio does not match.
- Existing and proposed elevations where only the proposed have been provided.
- A missing biodiversity net gain statement or exemption declaration, which is now part of many local lists for applications caught by the statutory regime.
- No completed community infrastructure levy additional information form, where the authority charges the levy.
- A site location plan that does not show two named roads or enough surrounding context to locate the site.
- A supporting statement referred to on the form but not uploaded.
None of these is an argument. Fix them and resubmit the same day. The only one worth a conversation is the biodiversity net gain paperwork, where the exemptions are complicated and a validation officer may have applied the wrong one.
Challenging a requirement as unreasonable
Where the disputed item is a local list requirement that does not fit the development, respond in writing rather than by telephone, and make the argument in the terms the Order uses.
- Identify the requirement and quote the entry from the council's published local list.
- State when the list was published, and say so if it appears out of date.
- Explain why the requirement is not reasonable having regard to the nature and scale of this development.
- Explain why the information would not be a material consideration in this case.
- Offer an alternative where one exists, such as a short technical note instead of a full assessment.
- Ask for the application to be validated, and for written reasons if it is not.
Keep it to one page. A measured letter that engages with the statutory test is treated differently from an argument about how long the applicant has been in practice.
Where the requirement is arguably relevant but disproportionate, supplying a short, well-targeted document is often faster than the dispute. A focused Planning Statement that addresses the point in two pages can discharge a local list item that would otherwise be met with a specialist report.
Escalating within the authority
If the validation team will not move, escalate once, to the development management team leader or manager, with the same letter attached and a short covering note.
Set out what you want: validation, or written reasons identifying the requirement relied on and the date it was published. Ask for a response within five working days. Copy the case officer if one has been allocated.
Beyond that the formal options narrow. There is no right of appeal against non-validation, because there is no decision to appeal against. Judicial review is available where the authority has acted unlawfully, on a six week clock, and it is rarely proportionate for a single application. A formal complaint through the council's corporate procedure, and then to the Local Government and Social Care Ombudsman, is slower but costs nothing and does produce change in authorities that receive repeated complaints about the same requirement.
In most cases the commercial answer is to supply the document under protest, note the cost, and raise the requirement when the council next consults on its local list.
The effect on the determination clock
The statutory period runs from the date the application is valid, not the date it was submitted. So every week spent in dispute is a week added to the programme, and the target date on the planning register will reflect the later date.
There is a second consequence for fees. Where an application is not validated, the authority will normally return the fee or hold it against a resubmission, but the planning guarantee and any refund entitlement run from validation, so a long dispute delays those too.
Validating first time
The habits that avoid all of this are unglamorous.
Download the council's local list on the day you start the drawings, not the day you submit. Read it against the scheme and make a list of documents with owners and dates. Use the council's own validation checklist as the submission index. Check the certificate against the title, including any ransom strip. Call the duty planner about anything ambiguous and record the answer in an email back to them.
And submit on a Tuesday. Applications submitted late on a Friday sit in the queue over the weekend and are checked when the backlog is deepest.

Frequently asked questions
Is there a right of appeal against a refusal to validate?
No, because there is no decision to appeal against. The routes are a written challenge to the validation team setting out why the requirement fails the statutory tests, escalation to the development management manager, a corporate complaint and then the Ombudsman, or judicial review where the authority has acted unlawfully, on a six week clock.
What can a council put on its local validation list?
Information that is reasonable having regard to the nature and scale of the development proposed, and that relates to a matter it is reasonable to think will be a material consideration. The requirement must also have been published, and the Order limits how long a local requirement can be relied on before it is reviewed.
When does the eight week period start?
From the date the application becomes valid, not the date it was submitted. Every week spent in a validation dispute is added to the programme, and any fee refund entitlement also runs from validation. That timing is the main reason most applicants supply a disputed document under protest rather than argue.
What are the most common reasons applications are rejected at validation?
The wrong ownership certificate, an incorrect fee, drawings without a scale bar, north point or drawing number, missing existing elevations, an incomplete levy information form, a location plan showing too little context, and documents referred to on the form but not uploaded. None of these is worth arguing about.
Can I reduce the risk of rejection before submitting?
Download the council's local list when you start the drawings rather than when you submit, and use its validation checklist as your submission index. Check the ownership certificate against the title, including any access strip. Ask the duty planner about anything ambiguous and confirm the answer by email.
