What the data tells us

1
The range is massive: 96.6% to 98.6%. Choosing the right project type — or framing your application correctly — can dramatically affect your chances.
2
Visibility drives risk. Project types that change the external appearance — dormers, loft conversions, hip-to-gable — face more resistance than those that don't. The more visible your proposal, the more carefully it needs designing.
3
These are council-wide averages. Your ward, your street and your immediate neighbours all shift the odds. The comparable decisions near your property are the best predictor of outcome.
