Validation refusal and the cost of a rejected application

An invalid application has not been refused. It has not been submitted. The statutory clock never started, the case officer has not read a word of it, and the eight or thirteen weeks you promised the client begins again on the day the missing item arrives. That is the whole cost of invalidation, and on a commercial scheme it is usually measured in finance rather than fees.

Validation is a clerical check against two lists. It is also, in many authorities, the slowest part of the process, because the validation team works through a queue and a rejected application goes to the back of it.

What validation actually checks

The national requirements sit in the development management procedure order. In broad terms an application needs the completed form, the correct certificate of ownership and, where relevant, the agricultural holdings certificate, a location plan identifying the site by a red line, any plans and drawings necessary to describe the development, and the correct fee.

Some documents are national requirements only in defined circumstances. A Design and Access Statement is required for major development and for smaller schemes in a conservation area or World Heritage Site above defined thresholds, and for listed building consent applications. A fire statement is required for applications relating to buildings meeting the height and use criteria in the procedure order.

Since the biodiversity gain regime came into force, applications for planning permission must also include the prescribed biodiversity information, including a statement as to whether the applicant believes the biodiversity gain condition applies. Leaving that out invalidates an otherwise perfect application, and it is now one of the most common reasons for rejection on small schemes.

National and local requirement lists

On top of the national list, each authority publishes a local list of information requirements. That list has to be published, has to be kept current, and the items on it have to be reasonable having regard to the nature, scale and location of the development.

The practical consequences are worth stating plainly. A requirement that is not on the published local list cannot be used to invalidate your application. A local list that has not been reviewed within the period national guidance expects is open to challenge. And a requirement written for major development should not be applied to a householder extension.

Download the current local list as a PDF at the point you start the drawings, not the week you submit. Authorities update them, and the version cached in your office from two years ago is a liability.

The items most often missing

The pattern is consistent across authorities, and almost none of it is technical.

• Ownership certificate signed on the wrong basis, usually Certificate A where part of the access strip belongs to someone else
• Location plan without a scale bar, north point or correctly drawn red line, or a blue line missing on adjoining land in the same ownership
• Existing drawings omitted, so the proposed cannot be assessed against anything
• Drawings marked "do not scale" or issued at a scale the authority does not accept
• The biodiversity information statement absent
• CIL additional information form not submitted where the authority charges the levy
• A Design and Access Statement missing on a site inside a conservation area where the threshold was met
• A Fire Statement missing on a relevant building, which is a professional-led document and cannot be produced overnight

The last two are the expensive ones, because they cannot be fixed by amending a drawing. Fire statements in particular require someone with fire engineering competence, and a scheme that discovers the requirement at validation loses weeks rather than days.

Whether the fee comes back

Where an application is invalidated and not pursued, authorities generally return the planning fee. The service charge levied by the national application portal is a separate payment and is not part of the planning fee.

What you do not get back is the time. The statutory determination period runs from the day after a valid application is received, so invalidation resets it entirely. Where the authority does eventually validate, the fee regulations also provide for a refund of the planning fee if the application is not determined within a defined longer period, which is a modest consolation on a scheme that is already late. Planning fees for a new dwelling and the sliding scale covers how the fee itself is calculated.

What the delay really costs

Build the number rather than describing it. For a small commercial scheme, four lines usually capture it.

An illustrative case. A conversion scheme is submitted in the first week of a month and rejected nine days later for a missing biodiversity statement and an unsigned ownership certificate. The corrections take two days. Resubmission goes back into a validation queue and the application is validated three weeks after the original date. The determination date moves by three weeks, and because the contractor's fixed price expires at quarter end, the scheme loses a further month waiting for a re-tender. The fee was refunded and returned in full. Nothing else was.

Challenging an unreasonable requirement

You can push back, and sometimes you should.

1. Check the item against the authority's current published local list, and note whether the list is within its review period.
2. Check whether the requirement is expressed to apply at the scale of development proposed.
3. Write to the validation officer citing the list and the scale test, and copy the case officer. Offer to supply the information as a condition or during determination instead.
4. Where the authority holds firm and you believe the application was valid when submitted, one formal route is to allow the statutory period to run and appeal against non-determination, but that is a slow and risky answer and should not be taken without advice.

In most cases the faster commercial decision is to supply the document and argue afterwards. Keep a note of the exchange, because a pattern of unreasonable requirements is worth raising through the agents' forum most authorities run.

A pre-submission check that works

Give one person the job of validating your own application against both lists before it leaves the office, and give them the checklist rather than the drawings.

Print the national requirements and the local list. Tick each item against a named file in the submission folder. Check the certificate against the title plan rather than against memory. Open every PDF and confirm the scale bar and north point are visible at the size it prints. Confirm the fee against the current fee schedule, since it is indexed annually. Then check the description of development matches what the drawings show, because a description that omits the change of use is the one thing validation will not catch and the case officer will.

Fifteen minutes of that beats three weeks in a queue. If you want the supporting documents drafted and structured before that check, browse the report types and start from the ones your local list names.
