Westminster is slower than most councils at deciding householder applications, ranking #227 out of 292. Only 27% of applications have the time limit extended, well below the 40% national average - the council usually decides on time. Westminster is also one of the strictest councils - it refuses more householder applications than almost any other, with only 79% approved vs 90% nationally.
