Oxford is slower than most councils at deciding householder applications, ranking #261 out of 296. The council extends the time limit on 57% of applications - one of the highest rates in England. Expect your application to take longer than the standard deadline. Householder applications are slightly less likely to be approved here (89%) than the national average (90%).
