What the data tells us

A 14.7% gap separates the best and worst wards. Not Applicable - Adj Authorityl approves 92.3% of applications while Bentley Heath & The Royds approves just 77.6%. That's a fundamentally different planning environment.

High volume doesn't mean high approval. Some of the busiest wards aren't the most permissive. The number of applications a ward processes tells you nothing about how likely yours is to succeed.

Ward averages are a starting point, not a guarantee. Your specific outcome depends on your property, your neighbours, your proposal type and the comparable decisions near your address.
