How Long Does Planning Permission Take?

The statutory answer is eight weeks. The measured answer, across 2,094,240 real decisions, is 10.7 weeks, and 90% of English councils run over the statutory period on average. This page is the working: every council, every project type, every figure traceable to the council's own record.

English councils grouped by average decision time, all application types, validation to decision. Everything right of the dashed line runs over the statutory eight-week period.
The eight-week myth: official statistics look far healthier. MHCLG reports 93% of householder applications decided “within eight weeks or the agreed time. The load-bearing phrase is the agreed time: if a council cannot decide within eight weeks, it asks the applicant's written consent to extend, and an extended decision still counts as on time. PlanningLens ignores the paperwork and measures the calendar: validation date to decision date, per application, from each council's own portal.

Where the weeks go #

The statutory clock starts at validation, not submission. Checking that a new application is complete can take a week or two on its own, and if documents are missing the clock does not start until you resubmit. That is also why measures counted from submission read differently from the validation-basis figures on this page.

Once validated, a typical householder application moves through neighbour consultation (a 21-day statutory window), officer assessment, and a delegated decision, and each stage has a queue. One complication is usually all it takes to pass the statutory period: an objection, a request for amended plans, or a referral to planning committee, which then waits for the next committee date.

The eight-week period applies to householder and minor applications. Major applications carry thirteen weeks, and cases needing an environmental impact assessment sixteen. The named-council league tables on this page are householder applications only, so the eight-week comparison there is exact.

† Scotland's statutory period for local developments is two months rather than eight weeks.

London is measured as a region: 10.4 weeks on average across 881,573 decisions in 30 boroughs. On the householder measure, the slowest borough in 2025 was Camden at 12.0 weeks and the fastest was Redbridge at 5.7 weeks.

Not named: Birmingham, Liverpool, Sheffield, Newcastle upon Tyne, Cardiff, Edinburgh. Their portals do not currently publish decision records that pass the date-quality gates at the naming threshold, so no figure is claimed for them.

Northern Ireland: measured against its own 15-week target #

Northern Ireland's statutory target is different: local applications should be processed within an average of 15 weeks, not eight. Even so, DfI's own statistics show local applications averaging 19.0 weeks in 2024/25, with three of eleven councils meeting the target. DfI's measure is a median that includes withdrawals, so it is not directly comparable with the mean-of-decided figures below (see NI Assembly research briefing, Jan 2026).

On PlanningLens's measure (householder applications, validation to decision), Newry, Mourne and Down averaged 34.4 weeks in 2024 across 143 decisions, with 98% taking longer than eight weeks: more than double NI's own 15-week target. Mid & East Antrim, by contrast, decides householder applications faster than most of England.

Are decisions getting faster? #

The honest trend needs the same councils every year: a rising line can otherwise just mean slower councils joined the data. This panel holds membership constant: 71 English councils with at least 20 householder decisions in every year 2020–2025. Times peaked in 2022 at 10.4 weeks and have eased since, but the panel average has exceeded the eight-week statutory period in every year shown.

Who moved most since 2020? #

Same measure at both ends: councils with at least 50 householder decisions in both 2020 and 2025. 84 GB councils qualify. Improvement and rank are different questions: a council can cut its times sharply and still sit among the slowest. The second table shows who cut them most.

Why do published estimates differ? #

Three kinds of number circulate for the same question. They differ because they measure different things. Here is the reconciliation, so you can pick the right one for your purpose.

Actual elapsed weeks, validation to decision, per application, per councilNo extension paperwork, no survey returns: the council's own published dates, measured. Householder figures for league tables; all-types figures for scale. Every number links to method and sample size.

None of these is wrong; they answer different questions. If you want to know how long you will wait, elapsed calendar time in your council is the number that matches your experience.

Once decided, most applications succeed: across PlanningLens's quality-filtered dataset, councils approved 88.5% of decided applications, while 395,060 were refused. Refusal patterns vary sharply by council and ward.

Quick answers #

The short versions, for anyone arriving in a hurry. The full workings are in the sections above, and these are the same answers the page publishes to search and answer engines.

How long does planning permission take in England?

On average 10.7 weeks from validation to decision, measured across 2,094,240 real decisions in 209 English councils, against a statutory period of eight weeks for most applications. 90% of councils take longer than eight weeks on average.

Why do councils say eight weeks if it takes longer?

Eight weeks is the statutory determination period. Official statistics count a decision as "in time" if it was made within eight weeks OR within an extension of time the applicant agreed to in writing, so headline performance figures include extended deadlines. PlanningLens measures actual elapsed calendar time.

How long does a loft conversion or extension take to approve?

In 2025, householder averages ranged from 9.02 weeks (Single Storey) to 11.37 weeks (Two Storey) nationally. Individual councils vary from under four weeks to over eighteen.

Which councils are slowest at deciding planning applications?

On 2025 householder decisions, the slowest ranked GB council was Melton at 18.9 weeks. In Northern Ireland, which has its own 15-week statutory target, Newry, Mourne and Down averaged 34.4 weeks in 2024.

Are planning decisions getting faster or slower?

On an identical panel of 71 English councils, householder decision times peaked at 10.4 weeks in 2022 and eased to 9.1 weeks in 2025. That is still above the eight-week statutory period, which the panel average has exceeded in every year since 2020.

Method & data: Two measurement layers, never mixed. Named councils and league tables use householder applications only (loft conversions, single- and two-storey and rear extensions), validation date to decision date, decisions of 0–364 days, minimum 50 decisions per council-year, with sub-1-week portal artifacts excluded. Scale figures (the 10.7-week England average and decision counts) use all application types on the same validation-to-decision basis, decisions of 0–730 days, councils with at least 50 timed decisions. Nations are assigned by ONS GSS code. Northern Ireland is reported only in its own section, against its own statutory regime, on the householder measure. Decision-time trust is governed by date-quality gates that are separate from the approval-rate quality filters used elsewhere on this site: a council can be excluded from approval rankings yet have sound decision dates, and vice versa. Every figure regenerates from 295 councils' portal records (3,429,906 applications indexed) and self-labels its snapshot date. Full details: methodology · complete league table.
