Published 21 August 2025

Applies to England

1. Introduction

This report provides information on how the Planning Inspectorate has performed against measures by which Ministers agreed to assess the organisation’s casework performance for appeals.

These measures are:

A. Appeals valid on first submission B. How long appeals take o There is also an ambition for more consistent, timely decisions C. Customer satisfaction D. Number of cases quality assured

Full details of these are available

For measure A, this report covers the period January 2024 to March 2025.

Measure B covers the 12 months from July 2024 to June 2025.

For measure C, survey fieldwork was carried out in April and early May 2023.

Measure D covers the three months April to June 2025.

These statistics are designated as Official Statistics in Development. Any feedback would be welcome. Please send comments to statistics@planninginspectorate.gov.uk

2. A. Appeals Valid on First Submission

Ambition: Proportion rising annually and ambition to reach 100

For appeals received during January – March 2025, 52.1% were valid first time. Table 1 shows the proportion valid on first submission over the year.

The figures in this time series are revised at each publication as some cases take many months to be validated.

3. B. How Long Appeals Take

Ambition: As an initial milestone in making more consistent, timely decisions - The Planning Inspectorate should be working towards consistently achieving decisions in these ranges: Appeals decided entirely using written evidence in 16 – 20 weeks. Appeals decided including at least some evidence through hearing or inquiry in 24 - 26 weeks (30 weeks to recommendation for called in or recovered cases)

This section provides information on how long it has taken to make decisions in the last 12 months (in this case, July 2024 to June 2025).

Figure 2 below shows the proportion of cases decided:

• within 20 weeks;
• within 26 weeks (but more than 20 weeks);
• within 52 weeks (but more than 26 weeks); and
• more than 52 weeks.

The data applies to all cases decided in the year to the end of June 2025 and is broken down by the procedure used to arrive at the decision. The data for this Figure is available at Annex B.

Figure 2 shows that a much smaller proportion (10%) of cases decided by written representations take more than a year than those decided by hearings (24%) or inquiries (23%).

It also shows that a greater proportion of cases decided by written representations are decided within 20 weeks (28%) than those decided by hearings (20%) or inquiries (7%).

Measures set by the Minister that apply to cases decided wholly by written representations are shown in Annex C.

Consultation If you would like to make a suggestion on which information you would like to see; or would like to have the chance to comment on any proposals on what is published, please contact us via statistics@planninginspectorate.gov.uk

Figure 2 shows the proportion of cases decided in time bands. Figure 3 below shows more detail. It gives the full spread of time taken to decide cases, providing visibility of those cases far outside the accepted range. It shows all cases decided in the 12 months to the end of June 2025; and a breakdown by the decision procedure.

Figure 3 shows:

• The spread of time taken to decide for all cases, is similar to the spread for those decided wholly by written representations. This is because the large majority (17,367/18,778 which is 92%) of cases are decided this way.
• Three quarters of cases decided wholly by written representations are decided within 36 weeks. The corresponding time for three quarters of cases decided wholly or partly by hearings is 49 weeks and for those wholly or partly by inquiries is 51 weeks.
• Nine in ten cases decided wholly by written representations are decided within 52 weeks. The corresponding time for nine out ten cases decided wholly or partly by hearings is 87 weeks and for inquiries it is 90 weeks.

Figure 3 – Spread of time taken to decide cases (in weeks), for cases decided July 2024 – June 2025

Note: The figure for “Half the decisions are made within” is the 50th percentile; this is the same as the median time to decide these cases, which is how this is presented in the quarterly Official Statistics publication.

The Ministerial measure requires information on how long appeal decisions take from valid receipt to decision , with information on various percentiles.

Ambition: Decision time for 50th percentile falling. Decision time for 90th percentile falling faster than 50th percentile.

The ambition is that cases are decided more quickly, and the time taken for longest cases is reduced. If the ambition is met, the gap between the 50th percentile and 90th percentile needs to reduce.

A percentile is a measure that shows the value below which a given percentage of the values in a group of numbers fall. For example, if we tell you the 25th percentile for decision times, then you know that 25% of decisions are issued in less time (or the same time) as that.

Table 2 below shows the 25th, 50th, 75th and 90th percentiles for valid to decision, in weeks, for the decisions made from July 2024 to June 2025. Note that these match the timings given in text on the shapes in Figure 3 above.

Procedure	25th percentile	50th percentile	75th percentile	90th percentile	100th percentile	Number of decisions
Written reps	19 weeks	27 weeks	36 weeks	52 weeks	191 weeks	17,367
Hearing	21 weeks	28 weeks	49 weeks	87 weeks	302 weeks	977
Inquiry	25 weeks	32 weeks	51 weeks	90 weeks	210 weeks	434
All	19 weeks	27 weeks	36 weeks	55 weeks	302 weeks	18,778

If performance changes, it will be more quickly apparent by looking at quarterly data than 12 monthly data. Annex E shows the same percentiles, for decisions in the three months April to June 2025.

There are relatively few hearings and inquiries in each quarter, which means quarterly percentiles for these appeals are susceptible to extreme values - so they should be viewed with caution.

The table above covers all appeal decisions. Annex F gives figures for appeals decided wholly by written representations; wholly or partially through hearings; and wholly or partially through inquiries.

4. C. Customer Satisfaction

Ambition: Proportion of customers reporting satisfaction with the Planning Inspectorate’s services rising annually

No new analysis relevant to this measure is presented this quarter. The Planning Inspectorate have worked with the Institute for Customer Service to conduct a satisfaction survey. The data capture phase was carried out in April and early May 2023. The results of this survey show that Planning Inspectorate was given an overall satisfaction score of 56.8.

It is not simple to compare these customer service results against other organisations, given the nature of the services the Planning Inspectorate provides. For instance, based on customer complaint data, almost a half of the complaints that the Inspectorate received were complaints about an Inspector’s decision, rather than a complaint about how the process was run.

The results suggested that the organisation is underperforming in these key areas: - Experience - Complaint handling - Customer Ethos - Emotional Connection - Ethics

Action plans will be put in place to address these areas of concern to optimise, evolve and ultimately improve our performance.

This survey will be repeated this year to compare our progress in this area.

5. D. Number Of Cases Quality Assured

Ambition: There is no minimum number or percentage ambition on this measure.

During the three months April to June, 1,178 appeal cases were quality assured. These are shown in Table 4 below.

Table 4 - Number of appeal decisions quality assured, April to June 2025

Number	Category	Explanation
143	Inspector Manager team reading	Inspector Managers are expected to review a proportion of their Inspectors’ decisions post-decision. This is to ensure quality standards and to identify learning opportunities and to check for consistency with the relevant quality framework.
204	APOs	Recommendations made by Appeals Planning Officers (APOs) are all reviewed as part of routine quality assurance before a decision is issued by an Inspector.
831	Inspector in Training – pre-decision	Most decisions made by Inspectors in Training (IITs) are reviewed for teaching purposes. Each review is by an experienced Inspector.
1178	Total Appeal decisions

Source: MiPINs

To put these totals in context, the 1,178 appeal decisions quality assured constitutes approximately a quarter (24%) of all decisions (4,840) issued over that period.

Table 5 shows the number of cases quality assured, beyond appeal cases, for the same quarter. These are much larger, more complex cases than the typical appeal case.

Table 5 - Number of Other Cases Quality Assured, April to June 2025

Number	Category	Explanation
5	Local Plans	All Local Plans are quality assured as part of the examination process. Five Local Plan Report was issued in this quarter; quality assurance also took place for plans yet to be published.
6	Nationally Significant Infrastructure Projects (NSIP)	All NSIP decisions are quality assured as part of the examination process. 6 recommendation reports were submitted to the Secretary of State this quarter.
