Lapsed permissions, withdrawn appeals and the route back

A planning permission that has run out of time cannot be renewed. There is no extension application, no revival procedure and no discretion for the council to put the clock back. What you have is a fresh application on a site where the planning history shows the authority once found the proposal acceptable, which is useful but is not the same thing as a live consent.

That is the uncomfortable starting point, and it catches self-builders more often than anyone else, usually because a plot was bought with a consent that had eighteen months left on it and the finance took two years to arrange.

Standard time limits and how they are counted

The default conditions come from the Town and Country Planning Act 1990.

A full permission must be begun within three years of the date of the grant, under section 91. The three years runs from the date on the decision notice, not from the date the application was validated or the date the committee resolved to approve.

An outline permission works differently, under section 92. The application for approval of reserved matters must be made within three years of the outline grant, and the development must then begin within two years of the final approval of the last reserved matter. Both limbs have to be satisfied. A reserved matters application submitted in year four is too late however good it is, and the outline permission is gone.

The authority can impose different periods, longer or shorter, where it gives reasons. Long phased consents frequently carry extended periods, and conversely a permission for something sensitive may carry a shorter one. Read the condition rather than assuming three years.

Two counting traps. A section 73 permission granted to vary a condition is a new permission, and the time limit runs from the original grant rather than being reset, so a variation obtained in year two does not buy three more years. And where a permission has been the subject of a non-material amendment under section 96A, the original time limit stands.

What amounts to lawful implementation

Beginning development is defined by section 56 of the 1990 Act, and the list of qualifying material operations is narrower than people assume. It includes work of construction in the course of erecting a building, digging a trench for the foundations, laying any underground pipe or main to the foundations, constructing a road or part of one, any demolition work that is part of the development, and in the case of a change of use, making that change.

So the operations that commonly count are the foundation trench, the site road and demolition. The operations that commonly do not count are site clearance, erecting hoarding, installing a site cabin, stripping topsoil and setting out pegs.

Two qualifications matter more than the list.

First, the work has to be a genuine start on the development permitted, not a token gesture carried out solely to keep the permission alive. The courts have accepted modest operations as sufficient, but they have also held that work which is merely colourable, carried out with no intention of proceeding, may not amount to a lawful start. A single trench dug with no follow-up and no intention to build is vulnerable.

Second, and more often fatal, the start must not be in breach of a condition that had to be discharged first. Where a condition precedent requires something to be approved before any development begins, works carried out before that approval are unlawful, and the established principle is that unlawful works cannot operate to implement the permission. A permission can therefore expire while the applicant believes it has been implemented.

That principle is the single most common way self-build consents are lost. Discharge every condition precedent before touching the ground, keep the written approvals, and photograph the works with dates.

Where you need certainty afterwards, a Lawful Development Certificate for an existing use or operation under section 191 is the formal way to establish that development was lawfully begun.

Whether a time limit condition can be varied

No, and this is a statutory bar rather than a matter of local discretion.

Section 73 allows an application to develop land without complying with a condition previously imposed, but subsection (5) specifically prevents the grant of permission under that section to change a condition about the time within which development must be started, or within which an application for approval of reserved matters must be made. The temporary procedure that allowed extensions of time during the financial crisis was time limited and no longer applies.

The Levelling-up and Regeneration Act 2023 inserted a further power to grant a varied permission, and both its scope and whether it is yet in force should be checked on legislation.gov.uk and gov.uk before relying on it for anything, because the detail affects what can be varied and by what route.

For practical purposes, treat the expiry date as fixed. The only decisions available to you are to begin lawfully before it, or to apply again.

Withdrawing an appeal and what it costs

An appeal under section 78 can be withdrawn at any point before the decision, by writing to the Planning Inspectorate.

The direct consequences are straightforward. The refusal stands and the decision notice remains on the record. The appeal cannot be reinstated, so a later challenge means a fresh application and, if refused, a fresh appeal.

The indirect consequences are where the cost sits. On written representations appeals, withdrawal early usually costs nothing beyond the fees already spent. Where an appeal has progressed to a hearing or an inquiry, the other party will have incurred costs in preparing evidence, and a late withdrawal can attract an application for costs on the basis of unreasonable behaviour. The Planning Inspectorate publishes guidance on costs awards, and the test turns on whether the party's conduct was unreasonable and caused the other party to incur wasted expense. Withdrawing at the door of an inquiry is the obvious example.

Note the deadlines if the question is whether to appeal at all. For most refusals the period is six months from the date of the decision notice, and for householder and minor commercial appeals it is 12 weeks. Those periods are not extendable in practice, so a decision to withdraw and reapply should be taken with the clock in view.

Free resubmission and its conditions

The fee regulations allow one further application without a fee where an earlier application was refused or withdrawn, subject to conditions. The conditions are the point, so read them rather than relying on the description.

Broadly, the exemption applies where the further application is for development of the same character or description, on the same site, by or on behalf of the same applicant, and is submitted within 12 months of the earlier decision or withdrawal. It is available once. A second resubmission attracts the full fee.

Three practical notes. The exemption applies to the planning fee and not to the costs of revising drawings and reports, which is usually the larger number. Changing the scheme substantially can take it outside "the same character or description", so a materially different proposal is a new application at full fee. And the authority decides whether the exemption applies, so confirm it with the validation team before submitting rather than arguing afterwards.

Starting again against reviving an old consent

Where the permission has lapsed, the options are narrower than they look.

The strength of a fresh application rests on how much the policy position has moved. A permission granted under a local plan that is still adopted, in a scheme unchanged, with no new constraint, is usually granted again. A permission granted under a plan that has since been replaced, on a site that has since picked up a nutrient neutrality requirement or a biodiversity net gain obligation, is a different application and may need evidence the original never needed.

The Planning Statement for a resubmission should set out the previous permission by reference number and date, state what has and has not changed in the scheme, and address each policy change since the original decision. Officers respond well to that because it tells them what they need to re-examine and what they do not. The report index covers the technical documents a lapsed consent may now need that it did not before.

Keeping a permission alive deliberately

If a consent is going to be held for a while, plan the implementation rather than improvising it near the deadline.

1. Read every condition and list the ones that must be discharged before any development begins.
2. Submit the discharge applications early, allowing eight weeks each and longer where a consultee is involved.
3. Obtain and keep the written approvals.
4. Carry out a material operation that is a genuine start on the permitted development, most commonly excavating the foundation trench in its approved position or constructing the site access road.
5. Record it: dated photographs, the contractor's invoice, a site diary entry, and a letter to the authority stating what has been done and when.
6. Keep the record with the title documents, because the question will be asked on sale or refinance.

One caveat on indefinite dormancy. Once development has lawfully begun the permission does not expire, but the authority can serve a completion notice under sections 94 and 95 where it considers the development will not be completed within a reasonable period, which if confirmed makes the permission invalid for anything not yet built. That is rare, and it is not a reason to avoid implementing, but it is a reason not to leave a half-built shell for a decade.
