How Long Does Planning Permission ACTUALLY Take?

How Long Does Planning Permission Actually Take in the UK?

Planning permission in the UK takes longer than most developers will tell you at the start of a deal. A straightforward application on a consented site might be resolved in eight months. A contested application on a complex site, appealed after a refusal, can take four to six years. Understanding the realistic range — and what drives the difference — is one of the most important things a landowner can know before they agree to anything.

The statutory timeline versus the real timeline

Local planning authorities are required to determine most applications within eight weeks for minor applications and thirteen weeks for major ones. In practice, most major residential applications significantly exceed those periods. A twelve to eighteen month determination period from submission is common. Two years is not unusual on contested sites.

The eight and thirteen week targets exist. They are routinely missed.

What happens before an application is even submitted?

The pre-submission phase is where most landowners are surprised by the time involved.

Before any application goes in, surveys are required. The number and type depend on the site, but a typical residential application on an edge-of-settlement or rural site will require most of the following: ecological survey (including bat surveys, which can only be conducted at specific times of year), ground conditions and contamination report, drainage and flood risk assessment, transport assessment, arboricultural report, and heritage or archaeological desk-based assessment.

Each survey has its own lead time and window. Bat surveys in particular can add six months to the pre-application period if they are missed in the first survey season. This is not a hypothetical delay — it happens on a significant proportion of sites.

Add pre-application consultation with the LPA, which is advisable on most sites and mandatory on some, and the period from agreeing to promote a site to submitting an application is typically nine to eighteen months.

What role does the local council play — and what about the parish council?

The local planning authority determines the application, but parish councils and local ward councillors have more influence on the outcome than most people realise.

A strong parish council objection, particularly one that is well-organised and politically connected, can shift a scheme from officer recommendation for approval to a committee referral — and from there, refusal is a real possibility regardless of the planning merits. Managing community relationships is not an optional extra on a contested site. It is part of the process.

What happens at planning committee?

Planning committee is where an application goes when it cannot be determined by officers under delegated powers — typically because it is contentious, above a certain scale, or has attracted significant objections.

At committee, planning policy matters. But so does presentation, local politics, and the quality of the case made on the night. An application that reads well on paper can fail at committee if it is not advocated effectively. This is not how it should work. It is how it does work.

What if the application is refused?

A refusal is not necessarily the end. The routes from a refusal are: appeal to the Planning Inspectorate (written representations, hearing, or public inquiry depending on the scale and complexity); resubmission with amendments to address the reasons for refusal; or renegotiation with the LPA to agree a consented scheme.

Written representation appeals take six to nine months. A planning inquiry — for larger or more complex schemes — takes twelve to eighteen months from lodging to decision.

The total elapsed time from agreeing to promote a site to resolving a planning appeal can therefore exceed five years on a contested application.

What does this mean for landowners?

Two things.

First, the option period on any agreement you sign needs to be long enough to accommodate a realistic planning timeline — including appeals. Standard option periods of two or three years are frequently insufficient. If the developer needs to exercise the option before planning is secured, you are exposed.

Second, the quality of the planning consultant and the promotion strategy matters enormously. The same site can produce a granted application or a refusal depending on how it is positioned, surveyed, and presented.

Land Ventures manages the full process on your behalf — from the initial site appraisal through surveys, application, committee, and if necessary appeal. We fund the process and are paid when your land sells.
