What the data tells us

1
A 9.3% gap separates the best and worst wards. Holbrook West approves 97.7% of applications while Cowfold, Shermanbury and West Grinstead approves just 88.4%. That's a fundamentally different planning environment.
2
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.
3
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.
