Planning appeal timescales and success rates

LATEST TIMESCALES (month of August)

For written representations appeals, the median number of weeks from an appeal being ‘valid’ to its Decision in August 2024 was 27 weeks for s78 planning appeals and 16 weeks for householder appeals.

Enforcement appeals by written reps in August 2024 had a median timescale of 47 weeks.  Hearings and inquiries generally take longer, but with a smaller number of cases the averages can be misleading.  Full details are on the Planning Inspectorate webpage.

Ministerial Measures on Timeliness of appeals

The latest Ministerial Measures on how quickly planning applications are decided were published on 22nd August 2024. They show further improvement in timescales and provide a handy picture to share with clients when they ask you, "How long....?"

SUCCESS RATES

Planning appeal success rates over the past quarter April-June 2024 averaged 28%, according to the latest statistics issued by the Planning Inspectorate.

The overall average obscures differences between different types of development and different appeal procedures. Certain types of development are generally more successful on appeal than other types, for example, major applications for 10+ dwellings have double the success rate on appeal compared to minor applications for under 10 dwellings, as shown in figure 2 below. Householder development also has a significantly higher success rate on appeal than appeals involving listed buildings.

Appeal success rates for written reps, hearings and inquiries

Written representation appeals (aqua line in the graph below) make up 93% of planning appeals so the overall appeal success rate (yellow) closely mirrors the average for this procedure.  The appeal success rates for April - June 2024 (Q1 2025) were 27% for written representations appeals and 28% overall for all s78 planning appeals.

Appeals through the Hearings procedure (orange line in the graph below) had a higher success rate of 40% last quarter but comprise only 4% of s78 planning appeals.  Inquiries (black line) had an appeal success rate of 46% last quarter but make up only 3% of s78 planning appeals.

Tempting as it is to ask for a hearing or an inquiry, the Planning Inspectorate has strict criteria for deciding when these procedures can be used, which can be found in Annex K of the PINS Planning Appeals Procedural Guide.
