What the data tells us

A 37.5% gap separates the best and worst wards. Cefn Fforest approves 100.0% of applications while Gilfach approves just 62.5%. 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.
