Colchester is faster than most councils at deciding householder applications, ranking #43 out of 296. Only 27% of applications have the time limit extended, well below the 41% national average - the council usually decides on time. Colchester is also one of the strictest councils - it refuses more householder applications than almost any other, with only 84% approved vs 90% nationally.
