Why rear extension approval rates matter

Rear extensions sit in the middle of the pack nationally. They're common enough that councils have clear precedent — but that cuts both ways. If your neighbours have been refused, that precedent works against you too.

Ward gap in Rugby: Eastlands approves 100.0% of rear extension applications while Dunsmore sits at 80.0%. That 20.0% gap means your postcode is one of the strongest indicators of outcome.
