What affects council approval rates?
Planning approval rates vary significantly between councils for several reasons. Councils in areas with high development pressure, conservation areas, and green belt land tend to refuse more applications. The type of applications submitted also matters — councils receiving more complex or speculative proposals will naturally show lower approval rates.
However, a council's overall rate doesn't tell the full story. Approval rates vary dramatically by ward, application type, and the specific nature of proposals. A council with a 70% overall rate may have wards where extensions are approved 95% of the time. That's why PlanningLens provides ward-level and type-specific data.

Frequently asked questions
What is the hardest council for planning permission in the UK?
Based on our analysis of 2,590,220 decisions, Uttlesford has the lowest approval rate at 72.4%, making it the strictest council for planning permission in our dataset. However, approval rates vary significantly by ward and application type within every council.
What is the average planning approval rate in the UK?
The average planning approval rate across the 240 councils in our dataset is 90.0%. This means roughly 10% of planning applications are refused nationally. Rates range from 72.4% to 99.7% depending on the council.
Why do some councils refuse more planning applications?
Councils with extensive conservation areas, green belt land, or high development pressure tend to refuse more applications. The mix of application types also matters — areas receiving more speculative or complex proposals will show higher refusal rates.
Does a low approval rate mean my application will be refused?
Not necessarily. Council-wide averages mask significant variation. A council with 75% overall approval may have wards where householder extensions are approved over 90% of the time. The specific ward, application type, and nature of your proposal all matter more than the headline rate.
