Extension of time against a fresh application for a lapsing consent
Time limit conditions cannot be extended by application in England. What counts as a material operation, why condition precedents defeat token starts, and when to reapply instead.
You cannot extend planning permission time limit conditions by application in England. Section 73(5) of the Town and Country Planning Act 1990 expressly prevents a section 73 permission from having the effect of extending the time within which development must be begun or an application for approval of reserved matters must be made. So when a consent is running out the real choice is between implementing it and applying again.
That is a harder decision than it looks, because implementation has to be lawful to count, and a fresh application will be decided against whatever policy exists on the day it is determined.
Whether a time limit can be extended at all
Section 91 imposes a default condition requiring development to begin within three years of the grant, and section 92 applies a two-stage limit to outline permissions: three years to apply for approval of reserved matters, then two years from the final approval to begin. Councils can impose a different period where there is a reason to, and some do, so read the decision notice rather than assuming three years.
There was a short-lived route to renew a permission before expiry, introduced during the recession and withdrawn in 2010. A separate temporary scheme under the Business and Planning Act 2020 allowed certain consents due to lapse that year to be extended. Both have gone, and neither is a precedent for a renewal application today.
What remains is section 73 for other conditions. You can use it to change a design detail, a materials schedule or an operating restriction. You cannot use it to buy more time.
Implementing to keep a permission alive
Development begun before the expiry date keeps the permission alive indefinitely, subject to the council's power to serve a completion notice. Section 56(4) defines when development is begun: the earliest date on which any material operation begins.
The listed operations are specific. Work of construction in the course of erecting a building. Demolition of a building. Digging a trench which is to contain the foundations, or part of them. Laying an underground main or pipe to a foundation trench. Any operation in the course of laying out or constructing a road or part of a road. Any change of use which itself amounts to material development.
The operation has to relate to the permitted scheme. Digging a trench in the wrong position, or on a line not shown on the approved drawings, is not a material operation for that permission even if a lot of soil moves.
The condition precedent trap
This is where most failed implementations go wrong. Works carried out in breach of a condition precedent are not a lawful commencement, so a start made before pre-commencement conditions are discharged may count for nothing. Permissions on complex sites commonly carry eight or more conditions precedent covering contamination, drainage, archaeology, tree protection, construction management and materials.
Discharging those conditions takes a fee per request and a determination period of its own. Eight weeks before expiry is too late to begin that process.
What counts as a material operation
The operations most often relied on, in rough order of how robustly they hold up, are construction of a section of foundation shown on the approved drawings, excavation of a foundation trench in the approved position, demolition where the permission includes it, and laying out part of the approved access road.
Weaker reliance includes site clearance, erecting hoarding, installing site cabins, soil sampling and setting out pegs. None of those appears in section 56(4). A digger moving topsoil is not, on its own, the beginning of development.
| Route | Fee | Policy applied | Main risk |
|---|---|---|---|
| Lawful implementation before expiry | Discharge of conditions fees per request | Policy at original grant | Start held unlawful because a condition precedent was outstanding |
| Fresh application | Full application fee for the category | Policy at the date of the new decision | Refusal, or a worse obligations and levy package |
| Section 73 variation | Reduced fee for a variation | Policy at the date of decision for the varied matter | Cannot extend the time limit at all |
A fresh application and the policy that will apply
A new application is determined on the development plan and national policy in force when it is decided, not when the original permission was granted. On a site where the local plan has since been replaced, where the site allocation has gone, or where the biodiversity gain condition now applies, a scheme that was acceptable five years ago may not be.
Three changes catch developers out. Mandatory biodiversity net gain under the Environment Act 2021 applies to applications made after the relevant commencement dates, so a fresh application brings the scheme into that regime even though the original did not. Policy on heating and carbon has tightened in many adopted plans. And affordable housing policy may now require a different tenure mix or a higher proportion.
Against that, a fresh application lets you correct the things that have proved awkward: a unit mix that no longer sells, a parking ratio the highway authority now accepts, an obligation that has become undeliverable. Whether it goes to committee or is dealt with under delegated powers depends on the council's scheme, and the practical difference between committee determination and a delegated decision is worth checking before you commit to a programme.
Risks of a token start on site
A minimal start is a legitimate tactic and a well-used one. It is not free of consequence.
Commencement triggers Community Infrastructure Levy liability where the charge applies. Regulation 67 of the Community Infrastructure Levy Regulations 2010 requires a commencement notice before development begins, and failure to serve it can mean the loss of the right to pay by instalments and, on exempted development, the loss of the exemption itself. A token start made without a commencement notice can therefore produce a demand for the full levy at once.
Section 106 triggers may also fire on commencement. Read the deed. Payments tied to "implementation" rather than to occupation become due on the day the trench is dug.
Then there is the completion notice power in sections 94 and 95, which allows a council to serve notice that the permission will cease to have effect unless the development is completed within a stated period of at least twelve months. It is used rarely, but a site left visibly half-started for years invites it.
Section 73 and condition variation limits
Section 73 remains useful alongside implementation. Vary the condition that has become impossible, discharge the ones that can be discharged, and keep the permission the same in substance. The permission granted on a section 73 application is a new permission, which means its own time limit condition is set by reference to the original, so it does not reset the clock.
Where the change goes beyond a condition, the amendment routes are narrower than people assume: section 96A for non-material amendments, and a fresh application for anything that alters the description of development.
Deciding six months before expiry
Six months out, do three things. Pull the decision notice and list every condition precedent with its current status. Price the discharge applications and the works needed for a lawful material operation. And get an honest read on what a fresh application would face under the current plan.
If the conditions can be discharged and a genuine material operation can be built, implement. If the policy position has improved or the scheme needs reworking anyway, apply again and use the time to fix it. If neither is comfortable, do both: implement to protect the fallback, then apply for the better scheme.
A draft Planning Statement for the fresh application can set out the planning history, the fallback position and the policy changes since the original grant, with the site facts it does not hold flagged rather than guessed.

Frequently asked questions
Can I apply to extend my planning permission?
Not in England. Section 73(5) of the Town and Country Planning Act 1990 prevents a section 73 permission from extending the time for beginning development or applying for approval of reserved matters. The earlier renewal route was withdrawn in 2010 and the 2020 temporary scheme has expired, so the options are implementation or a fresh application.
What counts as starting development?
Section 56(4) lists the material operations: construction work in erecting a building, demolition, digging a foundation trench, laying an underground main or pipe to the foundations, laying out or constructing a road, and a change of use amounting to material development. The work must relate to the approved scheme.
Does site clearance keep a permission alive?
Usually not. Clearance, hoarding, site cabins, soil sampling and setting out are not listed in section 56(4). A digger moving topsoil is not the beginning of development on its own. Rely on a foundation trench in the approved position or another listed operation instead.
Why can a start be held unlawful?
Because works carried out in breach of a condition precedent do not amount to a lawful commencement. On complex sites there can be eight or more such conditions covering contamination, drainage, archaeology and tree protection. Discharge them first, allowing for the fee per request and the determination period.
Does a token start trigger the levy?
Where the Community Infrastructure Levy applies, yes. Regulation 67 of the CIL Regulations 2010 requires a commencement notice before development begins. Failing to serve it can mean losing the right to pay by instalments and, on exempt development such as self-build, losing the exemption entirely.
Will a new application be judged on the old policy?
No. A fresh application is determined on the development plan and national policy in force at the date of decision. That can bring in mandatory biodiversity net gain, tighter heating and carbon policies and a different affordable housing requirement, even though the original permission predated them.
