Extension of time or refusal and resubmission

The extension of time versus refusal resubmission decision arrives in week seven, usually as a short email from the case officer. Agree four more weeks, or let the period expire. For an architect carrying a client who wants a start date, the choice looks like a scheduling question. It is not. It is a question about what the obstacle actually is, and the three routes available suit three different obstacles.

Agree an extension when the case is nearly there. Withdraw and resubmit when the scheme needs to change. Appeal non-determination when nothing is moving and nobody will say why.

The three options

Four rows for three options, because refusal and withdrawal lead to the same resubmission by different doors and the difference between them matters more than people expect.

What accepting an extension costs you

Mechanically, an extension is a period agreed in writing between you and the authority, which moves the date from which the right of appeal against non-determination under section 78 of the Town and Country Planning Act 1990 arises. Nothing else about the application changes.

What you give up is modest but real. The appeal right is deferred to the new date. The entitlement to a fee refund under the planning guarantee, where an application takes more than 26 weeks without an agreed extension, falls away. And you lose the pressure that an approaching deadline puts on a caseload.

What you keep is more valuable in most cases. The officer who has read the file, visited the site and formed a view stays on it. The consultation responses already received stay on it. And any amendment you have negotiated stays live rather than needing to be resubmitted as a new scheme.

So the test is simple. Is the delay doing work? If the lead local flood authority has asked for infiltration testing and the results are three weeks away, the extension is buying you an approval. If the officer has told you the scheme is too tall and nothing is under discussion, it is buying you nothing.

What a resubmission involves

A resubmission is a new application. That means a new validation check against the national and local lists, a new registration date, fresh publicity under article 15 of the Development Management Procedure Order 2015, a fresh round of consultee responses, and a new eight or thirteen week period.

Add it up honestly before you promise a client a date. Validation takes a week or two on a good day. Publicity runs at least 21 days. Consultees take their own time. A resubmission submitted in October is unlikely to be determined before the new year.

What you get in exchange is a clean assessment of a scheme that has changed. That is worth a great deal when the previous objection was about something a drawing can fix: a ridge height, a window position, a parking layout, a boundary relationship. Officers assess what is in front of them, and a scheme that visibly answers the earlier concern tends to be recommended for approval.

Two practical moves make resubmissions work:

1. Take the officer's concerns point by point in the Planning Statement, with a dimension or a drawing reference against each one. Do not make them reverse-engineer the response from a set of elevations.
2. Use the Design and Access Statement to show the options tested, including the earlier scheme, so the evolution is explicit rather than implied.

And prefer withdrawal over refusal where you already know what the problem is. A withdrawal leaves no reasoned refusal on the record, costs nothing in planning history terms, and officers generally welcome it because they would rather not write a report they expect to be superseded. Ask directly whether a withdrawal would be preferred.

Where you need the reasons in writing, because the client will not accept your account of them or because the design team disagrees, let it go to refusal. A refusal notice is a document with weight, and sometimes that is exactly what a project needs.

The fee position

This is where budgets go wrong, so handle it carefully.

The fee regulations have historically provided for one fee-exempt resubmission within twelve months of a refusal or withdrawal, subject to conditions about the same applicant, the same site and development of the same character. The regulations were amended in 2023 and planning fees are now indexed annually, so the availability and the conditions of that exemption should be checked against the current regulations and the authority's published schedule before you rely on it.

Practical approach: ask the authority's planning support team in writing whether a fee is payable on the resubmission, giving the previous application reference. Get the answer before you submit, because an application held as invalid over an unpaid fee loses weeks.

Budget the other costs too. Revised drawings, updated reports where the scheme has changed enough to affect them, and any new survey work. A resubmission that triggers a fresh ecology survey season is a far more expensive decision than the fee question suggests.

Appealing non-determination instead

Where the period has expired with no decision and no agreed extension, section 78 gives a right of appeal on the ground of failure to determine. It is the right lever when an authority has gone silent, and a courteous email saying you will appeal on a stated date often produces a decision without one.

As an actual route it has three drawbacks for an architect. The scheme is fixed as submitted, so an inspector cannot approve the amended version you were negotiating. Conditions and obligations cannot be shaped in the usual way. And the elapsed time commonly exceeds the delay you were escaping.

Use it where the application is sound, the delay is institutional and the client can absorb the programme. Avoid it where the scheme still needs to change.

How a holding objection behaves

This is the question that should decide the choice, and it is the one most often skipped.

A holding objection from a consultee comes in two forms. The first is evidential: the consultee wants information it has not been given, such as a drainage calculation, a visibility splay drawing or a noise survey. That objection is removable, it will be removed by the information, and an extension of time is the right answer because the resubmission would face the identical objection.

The second is a position on principle: the consultee considers the access unacceptable, the location unsuitable, or the harm unmitigable. That objection survives a resubmission intact. Changing the elevations will not move it. Before choosing a route, establish which highway authority has objected and read the objection closely enough to know which of the two forms it takes, because the whole decision turns on it.

A third pattern worth naming. Objections sometimes harden during an extension, as a consultee that initially asked for information consults internally and arrives at a position. That is an argument for resolving evidential objections quickly rather than letting an extension drift.

Choosing between them

A short sequence that works:

1. Ask the officer what is outstanding and what their current view of the scheme is. Most will tell you.
2. Classify each objection as evidential or principled.
3. If everything outstanding is evidential and deliverable within the proposed period, agree the extension, in writing, with a named date.
4. If anything is principled and a drawing can answer it, ask whether a withdrawal and resubmission would be preferred, and resubmit with the response set out explicitly.
5. If anything is principled and no drawing can answer it, decide whether to take a refusal and appeal on the merits, which is a different exercise from appealing non-determination.
6. If nothing is outstanding and nothing is moving, say you will appeal on a stated date, and mean it.

One honest uncertainty. The quality of the information you get at step one varies enormously between authorities and between officers, and on a case where nobody will give you a view, the decision becomes a judgement about the practice rather than about the scheme.

If a resubmission is the route, it is worth taking the time to scope the documents a resubmission needs afresh, because a changed scheme sometimes attracts reports the first application did not.
