Planning Inspectorate statistical release 20 June 2024

Published 20 June 2024

Applies to England

1. Introduction

This statistical release provides summary information on appeals, which represent the highest volume (in terms of number of cases) of the Planning Inspectorate’s work.

These statistics are produced each month and the focus is on timeliness of decision-making, an area of particular interest for stakeholders. Information on the decisions that have been made is also included; and on the number of Inspectors available to make those decisions.

These statistics have been published to ensure everyone has equal access to the information and to support the Planning Inspectorate’s commitment to release information where possible.

This statistical bulletin provides: - Appeals decisions and events held from June 2023 to May 2024 - The time taken to reach decisions - Provisional estimates of the number of open cases - Number of Inspectors

The Planning Inspectorate

The Planning Inspectorate makes decisions and provides recommendations and advice on a range of land use and planning-related issues across England.

The Planning Inspectorate deals with planning appeals, national infrastructure planning applications, examinations of local plans and other planning-related and specialist casework in England. The Planning Inspectorate is an executive agency, sponsored by the Department for Levelling Up, Housing and Communities.

1.1 Summary

Time to decide cases

The median decision time for cases decided in May was 26 weeks.

Median timeliness by procedure type is shown in the summary table below.

Procedure type	Last 12 months	May 2024
Written Representations	30 weeks	26 weeks
Hearings	32 weeks	24 weeks
Inquiries	44 weeks	40 weeks
All Cases	30 weeks	26 weeks

The median time for planning cases was 25 weeks in May 2024. The 12-month median was 28 weeks.

Enforcement decisions made in May 2024 had a median decision time of 52 weeks, with the 12-month median being 53 weeks.

The median time for planning appeals decided by inquiry under the Rosewell Process in May was 30 weeks and over the 12 months to May 2024 was 30 weeks.

Decisions

The Planning Inspectorate made 18,412 appeal decisions in the last 12 months, an average of 1,534 per month. The number of decisions in May 2024 was 1,571.

There were 1,442 written representations decisions in May 2024 and 17,165 in the last 12 months.

There were 753 decisions made on hearings during the last 12 months, and during May 2024, 78 decisions were issued.

There were 494 decisions made on inquiries during the last 12 months, with 51 in May 2024.

Planning Inspectors

There were 443 Planning Inspectors employed by the Inspectorate at the end of May 2024.

2. Decisions, Events & Open Cases

The number of decisions issued in May 2024 was 1,571, with a monthly average of 1,534 over the past 12 months.

The number of events recorded for May 2024 was 1,398, the average over the past 12 months was 1,527.

The median valid to decision time was 26 weeks in May 2024, as seen in Figure 1 and Table 1 below. The median valid to decision time for May is 1.6 weeks shorter than for April.

There are no clear trends for the number of events and decisions per month. However, the Christmas and Easter breaks do typically impact on the number of events arranged for December and April.

Figure 2 below shows the number of cases received, closed and open for each of the last 12 months. The number of cases closed has exceeded the number of cases received for each of the past 12 months, with the exception of March 2024.

Note – The number of cases closed is higher than the number of decisions, as it includes cases where an appeal is withdrawn, notice is withdrawn, or the appeal is turned away.

Note: there is a known anomaly that means that the number of open cases does not exactly follow the volumes of cases closed or received (for example the number of open cases can increase between months even though the number closed exceeded the number received). The main reasons for this have been identified and are detailed in the Background Quality Report.

Decisions by procedure and case type

Planning Inspectors work on a broader range of work than the appeals featured in this release. For example, they also work on examining Nationally Significant Infrastructure Project applications, Local Plans , Compulsory Purchase Order applications and many other specialist licencing/ application types.

Table 4 below gives the numbers of appeal decisions made broken down by whether the case was dealt with by written representations, hearings, or inquiries.

The large majority of decisions over the past 12 months (17,165) were made on written representations. This is 93% of all appeal decisions made. Table 4 shows that written representation decisions have varied from around 1,310 to around 1,560 per month over the past 12 months. There were 1,442 decisions in May 2024.

There were 753 decisions made on hearings during the last 12 months, the monthly average being 63. During May 2024, 78 decisions were issued. In May 2024, 51 decisions were made for inquiries. Decisions for inquiries per month over the last 12 months have ranged between 28 and 52.

What are Planning cases? The Planning category includes s78 planning appeals, householder appeals, commercial appeals, listed building consent appeals, advertisement appeals, s106 planning obligation appeals and Called In Planning Applications.

What are Enforcement cases? Enforcement covers enforcement appeals (i.e., appeals against the issue of an enforcement notice served by a local planning authority for alleged breaches of planning control), enforcement listed building notice appeals and lawful development certificate appeals.

What are Specialist cases? Specialist casework includes Common Land, Rights of Way orders (including Schedule 14 cases), Purchase orders, Tree Preservation Orders, High Hedges appeals, Hedgerow appeals, Wayleave, Compulsory Purchase Orders, Secretary of State, Transport, Environmental Permitting Appeals and Coastal Access. Additional casework types have been added to this category over time.

The large majority of cases decided over the past 12 months were planning (15,371). This is about 83% of all appeal decisions made. There were 2,314 enforcement decisions and 727 specialist decisions. These totals are also shown in Table 4 above and Figure 4 below.

Trends for planning decisions show similar patterns to written representations. The average number of enforcement decisions over the past 12 months was 193. Specialist casework figures continue to vary each month, from a high of 144 in March 2024 to a low of 33 in August 2023.

4. Decision timeliness

It is important for people to know how long an appeal is going to take, so that they can make informed plans and decisions. This section covers the timeliness of decisions (i.e., how long it takes to make a decision) across appeal casework. In addition to an overall measure, timeliness is analysed by procedure type and casework category, as timeliness varies a great deal depending on these characteristics.

Table 5 below shows that the median time to make a decision, across all cases in the last 12 months, was 30 weeks; and 26 weeks for May 2024. Figure 5 shows the median has ranged from 26 to 33 weeks for each of the last 12 months.

How is timeliness measured?

The time to make a decision is measured from the time the Inspectorate have enough information for the case to proceed (it is deemed ‘valid’) to the time a decision letter is issued. This means that any delay in ‘validating’ the appeal is included in the time to make a decision.

The decisions made in a given month will include those that started many months before, and thus do not give an accurate indication of how long appeals submitted, or deemed ‘valid’ in that month, will take.

Table 5 also shows the mean decision time for the last 12 months is 35 weeks. Each month the median is less than the mean, due to the impact of very long cases. Also included in the table is the standard deviation of decision timeliness, which is a measure of variation.

What are mean, median, and standard deviation?
Measure	Definition
Mean	The total time taken divided by the number of cases. Also referred to as the ‘average’. A measure of how long each case would take, if the total time taken was spread evenly across all cases.
Median	This is the time taken by the ‘middle’ case if all cases were sorted from quickest to longest
Standard deviation	This is a measure of variability or spread. It is calculated by examining how much each value differs from the mean. A higher standard deviation means the individual decision times vary more widely around the mean. A lower standard deviation would demonstrate greater consistency in the Planning Inspectorate’s decision timeliness.

Table 5: Median, mean and Standard Deviation of Time to Decision; June 2023 to May 2024

Month	Jun-23	Jul-23	Aug-23	Sep-23	Oct-23	Nov-23	Dec-23	Jan-24	Feb-24	Mar-24	Apr-24	May-24	Total

Procedure Type

Table 6 below shows decision timeliness broken down by the procedure type. Hearings and inquires have typically been more variable than written representations . Because 19 of every 20 cases are by written representation, the timeliness measures for written representations are similar to the measure across all cases.

Where a small number of cases has been decided, the average timeliness (whether mean or median) is less meaningful as a measure than where there are many cases. Those noted in the table caption below should be treated with caution as there are fewer than 20 cases decided.

Median times are less affected by a small number of large values than mean times, so are the focus of this commentary. The median time for written representations over the 12 months to May 2024 is 30 weeks. The median time for hearings over the 12 months to May 2024 is 32 weeks. The median time to decide for inquiries over the 12 months to May 2024 was 44 weeks.

Note 1: Where the number of decisions issued is fewer than 20, the measures mean, median and standard deviation are less meaningful.

Note: Tree Preservation Order cases are not included in timeliness measures

The standard deviation information indicates that for all three procedures, there is considerable variation, meaning times are widely spread about the mean. For written representations, the amount of variation has been quite stable over recent months, whereas inquiries have experienced considerable month to month changes in the spread of decision times.

Casework Category

The nature of the cases the Planning Inspectorate deal with varies widely and several factors play a part in determining how long it takes to make a decision. One such factor is the type of casework. Table 7 below shows the time taken to decide, in planning cases, in enforcement cases, and in specialist cases, as does Figure 6.

The median time to decision for planning cases (there are many more of these decisions than in the other categories) is lower than for enforcement cases; and less variable than the times for specialist cases. Table 7 and Figure 6 show the median time for planning cases has been 26 weeks and above for each of the last twelve months.

Note: Specialist casework timeliness measures exclude Tree Preservation Order cases

Annex A gives information on median and mean time to decision, with standard deviation, for the three procedure types, split by planning, enforcement, and specialist casework categories.

Enforcement decisions made in the past 12 months had a median decision time of 53 weeks.

There are considerably fewer specialist cases which means results are more liable to be distorted by extreme values.

Note: Specialist casework timeliness measures exclude Tree Preservation Order cases

Note that the Inspectorate publishes each month, information on the mean and median times from valid to decision, for selected appeal types. The information published also breaks down the time for each stage of the process. See Annex B for further details.

Planning Inquiry Decisions

For planning appeals decided by the inquiry process, The Planning Inspectorate has been implementing recommendations from the Rosewell review.

The median time for inquiries under Rosewell process over the 12 months to May 2024 is 30 weeks and the median time to decision for May 2024 was 30 weeks.

5. Open Cases

At the end of May 2024, the Planning Inspectorate had 13,137 cases open. More information on the number of open cases, and how it has changed over the past 12 months, is in Table 2 and Figure 2 above.

The open cases comprised of 11,721 cases being handled through written representations; 907 through hearings; and 467 through inquiries, as well as 42 not currently allocated a procedure type. This is not the number of ‘live’ hearings and inquiries since it includes cases where the event (hearing or inquiry) has yet to start, as well as those where the event has finished but the decision has yet to be issued.

Data separating open cases into those that have and have not yet had an event is not available for the end of May. We are working to fix this problem and hope to restore that additional information to Table 10 in the next publication.

Table 10: Open cases by procedure and stage, as of end of May 2024

Stage	WR	HRG	INQ	Total
Case received but yet to be deemed valid	348	29	4	381
Case deemed valid but yet to “start” [Note 1]	2548	171	137	2856
Case started but decision not yet issued	8825	707	326	9858
Total	11721	907	467	13095

Source: Horizon

Note 1 - there are 42 cases that have no procedure type recorded (see Background Quality Report for more detail) These are included in the total but excluded from the breakdown by procedure.

Note 2 – there is a known anomaly that means that the number of open cases does not exactly follow the volumes of cases closed or received (for example the number of open cases can increase between months even though the number closed exceeded the number received). The main reasons for this have been identified and are detailed in the Background Quality Report.

6. Inspectors

Table 11 below shows the number of inspectors in the Planning Inspectorate in each month from May 2023 to April 2024 . This includes headcount (i.e. the number of different individuals) and full-time equivalents (FTE) where those working part time are counted in proportion with their contracted hours. There were 443 Planning Inspectors employed by the Inspectorate in May 2024 – with a full-time equivalent of 399.

Tree Preservation order decisions have been removed from the average time calculations in this table due to problems with recorded validation dates, which mean that we are currently unable to accurately calculate their decision times.

8. Annex B – Detailed Information on timeliness (May 2024)

The information below is published today on the number and length of decisions made in May 2024 :

Note 1: when there are fewer than 20 decisions the measures mean, median and standard deviation are less meaningful

Casework Type	Procedure Type	Median (weeks)	Mean (weeks)	Decisions
s78 planning appeals	Written Representations	27.6	29.8	749
s78 planning appeals	Hearings	23.6	30.1	59
s78 planning appeals	Inquiries	30.9	41.9	28
Householder appeals	Written Representations	15.9	18.8	395
Enforcement appeals	Written Representations	52.9	57.7	149
Enforcement appeals	Hearings	43.8	46.8	16
Enforcement appeals	Inquiries	77.9	70.5	22

The smaller the number of decisions, the less helpful the mean and median are as measures for summarising performance. Particular care should be taken when there are fewer than twenty decisions.

The information published below shows the time taken for different stages of the appeals process:

	s78 planning appeals	s78 planning appeals	s78 planning appeals	Householder appeals
	Written Representations	Hearings	Inquiries	Written Representations
Weeks between valid date & start date
Median (average)	8.2	3.9	2.0	4.1
Mean (average)	7.7	7.5	3.1	4.8
Cases that started in April 2024	940	54	16	411
Weeks between start date & event date
Median (average)	12.3	13.7	16.0	8.7
Mean (average)	14.2	19.1	17.0	9.9
Cases where an event occurred during April 2024	685	43	13	338
Weeks between event date & decision date
Median (average)	4.0	3.4	12.2	3.0
Mean (average)	5.4	5.4	15.0	4.2
Cases that have been decided in April 2024	745	59	28	394

Note: Only cases with both dates recorded appear in this table, meaning that numbers for cases decided and events recorded may be lower than those presented elsewhere.

Explanation of date terminology

Valid date	When a case is deemed to have been validly received.  Note – this is not always the date the case was validated. If a case is validated after the date it was validly received, it is the date it was validly received that is the valid date.
Start date	When a timetable, on how the appeal will progress, is issued to both the appellant and local authority. This timetable tells the appellant when to submit the information the Inspectors need to determine the appeal. It also tells the local authority when to notify interested parties about the appeal.
Event date	When the site visit, hearing, or inquiry occurred.
Decision date	When the decision was issued by The Planning Inspectorate.

9. Annex C – Revisions to the data tables

This Annex lists all revisions made to the data since the last statistical release.

Note: Classed as a revision are any values which have changed by more than five (when measuring number of decisions/ cases) or more than 0.5 weeks (for mean, median or standard deviation of weeks).

Timeliness measures for all 12 months have been reproduced without Tree Preservation Order cases in this publication. This is due to problems with recorded validation dates, which mean that we are currently unable to accurately calculate their decision times.

10. Background notes

Data sources

Horizon / Picaso – The main casework management systems used for processing appeals casework (note that Picaso is no longer a live system).

SAP HR – The Human Resources system database used to store all information regarding members of staff.

Compliance with the Code of Practice for Statistics

These statistics have been published in accordance with the Code of Practice for Statistics, which cover trustworthiness, quality, and value. They have been pre-announced, and publication is overseen by the Head of Profession.

10.1 Technical Notes

A Background Quality Report is published alongside this Statistical Release. It provides more detail on the quality of statistics in this publication.

Data quality

Data on cases is taken from a live casework system, and details of cases can change for a number of reasons even after a decision has been made. We are seeking to get a better understanding of the nature and volume of these changes and will provide further information as it is available.

We carry out regular checks on the quality of our data and may undertake ad hoc data cleansing exercises.  Therefore, all the data for the last 12 rolling months is published in provisional form.

We have indicated in this publication any data where a number of cases has changed by more than five cases in a month; or where a measure (mean, median or standard deviation) has changed by more than 0.5 weeks.

Measuring weeks

Data are measured in days and then converted to weeks.

Note that not all decimal values are possible where converting days to weeks. 1 day is 1/7 of a week, or 0.14 weeks (to two decimal places). 2 days = 0.29; 3 days = 0.43; 4 days = 0.57; 5 days = 0.71; 6 days = 0.86.

When these are used to calculate averages, or displayed to one decimal place, the result will not equate to a full day which can be misleading: it may appear that we are measuring part days (e.g. 19.8 weeks) but we only measure in whole days.

Glossary

Term	Explanation
Appeals	The right to appeal a planning decision made by a local authority is a key feature of the planning system, as is appealing when an authority is taking too long.
Appeals decided	Number of appeals by the date the appeal was decided by The Planning Inspectorate.
Appeals received	Number of appeals by the date the appeal was received by The Planning Inspectorate.
Applications	Planning Inspectorate manage the application process for proposed Nationally Significant Infrastructure Projects (NSIPs) within England and Wales in line with the 2008 Planning Act.
Closed	The total number of appeals decided, withdrawn, or turned away.
Decision	The outcome of the case e.g. appeal allowed or rejected. The date of the decision is taken as the date a decision letter is sent to the appellant.
Event	A site visit, hearing, or inquiry (may be virtual)
Event Type	The different options of how an Inspector visits a site for a written representations appeal.
Examinations	The process of examining local plans is dealt with by the Planning Inspectorate. Every Local Planning Authority is required to have a local plan.  This includes a vision for the future and plan to address housing needs in the area.
Examinations	When a Local Planning Authority has finished preparing and consulting on a local plan it must be submitted to the Secretary of State who appoints an Inspector to carry out an independent examination.
FTE	Full Time Equivalent – a count of employees where those working part time are counted in proportion with their contracted hours.
Headcount	Total number of staff employed regardless of how many hours they work (i.e. the number of different individuals).
Hearings	A hearing involves the submission of written evidence by the main parties and a hearing once all the written submissions have been received.
Hearings	This takes the form of a round-the-table discussion (in person or virtually) that will be led by the planning inspector. It allows for all parties to respond to any questions that the inspector might have, and to let everyone make their case known.
Hearings	Source: Planning Portal
Inquiries	An inquiry is usually used for complex cases where legal issues may need to be considered. The main parties will usually have legal representatives to present their case and to cross-examine any witnesses. Prior to the inquiry date, the Planning Inspectorate will expect to have received various documents from all parties that will be taking part in the appeal. These may include statements of case and proofs of evidence from expert witnesses. Third parties may also take part. The inquiry will be led by the inspector and will follow a formal procedure.
Inquiries	At some point during or on conclusion of the inquiry the inspector and the main parties will undertake a site visit.
Inquiries	Source: Planning Portal
Live appeals	Number of live appeals in that have an appeal valid date but no end date (either decision date or a closed date, e.g. for appeals that have been withdrawn).
Mean	The total time taken divided by the number of cases. Also referred to as the ‘average’. A measure of how long each case would take, if the total time taken was spread evenly across all cases.
Median	This is the time taken by the ‘middle’ case if all cases were sorted from quickest to longest
Open Cases	Number of cases that have been received but on which a decision has not yet been made/ issued. Will differ from Live Appeals as it includes those received but not yet verified.
Procedure Type	The method by which The Planning Inspectorate processes and decides appeals.
Standard deviation	This is a measure of variability or spread. It is calculated by examining how much each value differs from the mean. A higher standard deviation means the individual decision times vary more widely around the mean.
Written Representations	Most planning appeals are decided by the written representations’ procedure. With this procedure the Inspector considers written evidence from the appellant, the LPA and anyone else who has an interest in the appeal. The site is also likely to be visited.
