Refused for insufficient information: resubmit or appeal

Refused insufficient information is the one refusal reason that usually points towards resubmission rather than appeal. The logic is simple. If the council says it cannot assess the scheme because a document is missing, supplying the document answers the reason, and supplying it to the council is quicker and costs less than supplying it to an inspector. The fees regulations also allow one further application on the same site without a fee in defined circumstances, which makes the arithmetic plainer still.

There are exceptions, and they matter. Where the missing information is contested, where the council has asked for something it is not entitled to, or where a second refusal would be worse than a slow appeal, the calculation changes.

Why authorities refuse for want of information

In theory a council should not validate an application that lacks documents on its local list. In practice several routes lead to a refusal on information grounds.

The application was validated, then a consultee asked for something nobody anticipated. The lead local flood authority wanting infiltration testing, the highway authority wanting a speed survey, the county ecologist wanting a protected species survey in a season that has passed.

The submitted document exists but does not do the job. A drainage statement with no run-off calculation. A heritage note with no assessment of significance. An arboricultural report that does not follow the relevant British Standard.

Or the officer has run out of time. A determination date approaching, an extension refused, and a refusal on information grounds is the defensible option.

Read which of these you are in, because they behave differently. The first two are curable. The third is a programme problem and sometimes better solved by agreeing an extension of time on a resubmission than by arguing.

Our note on why householder applications are refused covers the pattern across the smaller cases.

Can the gap be filled on appeal

Yes, and with caveats that people underestimate.

New evidence can be submitted with an appeal, and the inspector will consider it. Two constraints apply.

First, the scheme has to remain in substance the development that was applied for. An appeal is not an opportunity to submit a different proposal. Where amendments are offered, the inspector considers whether the development is still essentially what was before the council and whether anyone would be deprived of the chance to comment. Substantial change fails that test, and the appeal is then decided on the original scheme.

Second, the council has not assessed the new material, and neither have its consultees. An inspector faced with a drainage strategy the lead local flood authority has never seen may seek its view, which adds time, or may attach limited weight, which risks the appeal.

There is also a costs dimension running both ways. An appellant who produces at appeal a document that was available all along, and which would have avoided the refusal, is exposed to a costs application. A council that refused for want of information it was not entitled to require, or that had in fact been supplied, is exposed to one too. Our note on the appeal questionnaire and the council's statement sets out where the council's position becomes visible.

Timescales compared

Seasonal survey windows are the variable that overturns this table. If the refusal turns on a bat emergence survey and it is October, the survey cannot be done until May, and neither route can proceed sensibly before then. In that situation the appeal deadline becomes the thing to watch, because the right to appeal expires whether or not your ecologist can work.

Costs compared

The fees regulations allow a further application to be made without a fee where it is for development of the same character or description on the same site, by the same applicant, within a stated period after the earlier refusal, subject to conditions. The concession is available once. Check the current regulations for the qualifying conditions before you rely on it, because they include limits you can fall foul of, such as the earlier application itself having been a free one.

So the cost comparison usually looks like this. A resubmission costs the missing document, the drawing revisions and your fee, with no application fee. An appeal costs the missing document, the drawing revisions, a statement of case, and your fee for preparing and running it, with no application fee either but a longer engagement. Appeals cost more in professional time even at their simplest.

The exception is where the missing document is expensive and you think the council was wrong to ask for it. There, the appeal tests the principle, and winning removes the cost from this scheme and from the next one on a similar site.

A Planning Statement on the resubmission should deal with the refusal reason explicitly, saying which document answers it and where, because the officer assessing the new application is likely to be the one who recommended refusal.

Risk of a second refusal

This is the argument for the pre-application route, and it is stronger than it looks.

A second refusal on the same site does three things. It hardens the council's position, because two officers have now signed off the same view. It weakens your appeal, since the inspector reads a history rather than a single decision. And it uses up the free further application, so a third attempt costs a full fee.

Reduce the risk by doing three things before resubmitting:

1. Write to the case officer with the document you propose to submit and ask whether it answers the reason for refusal. Many will say yes or no, and that answer is worth more than a guess.
2. Send the technical document to the consultee that raised the point, where the authority permits direct contact, and get their position first.
3. Resubmit the same scheme unless design change is required. Changing the design as well as adding the document gives the officer two things to reassess and gives objectors something new to comment on.

Where the design does change, expect re-consultation and allow for it in the programme.

Choosing the route

A decision sequence that holds up for most self-builders and small developers:

Start by separating the reasons. If the notice refuses on information grounds only, resubmission is usually right. If it refuses on information grounds plus a substantive policy objection, the information point is a distraction and the policy point decides everything.

Then ask whether the missing document can be produced. If it depends on a survey season that has passed, lodge the appeal to preserve the right and take advice on whether to run it or withdraw once the survey is done.

Then ask whether the requirement is legitimate. Local list requirements have to be reasonable and relevant to the application. If you think a document has been demanded that the authority cannot require, say so in writing before deciding, and treat an unsatisfactory answer as a reason to appeal.

Finally, ask what a second refusal would cost your programme. If the answer is very little, resubmit. If a second refusal would kill the scheme's funding, the appeal may be the safer route even though it is slower, because an inspector's decision is final in a way a council's is not.

Our note on reading reasons for refusal before you decide to appeal covers the first pass through the notice in more detail.

One honest uncertainty: the free further application concession is drafted narrowly and councils apply it inconsistently. Ask the authority in writing whether it accepts that your resubmission qualifies, and get the answer before you submit rather than after.
