Where the activity is
Applications, grant rate and average estimated cost of works by parish — the same estimate model used on every row above, so "average cost" here means the same thing it does elsewhere on this page, just aggregated. A rough guide to where building activity concentrates, not a ranking of anything else about a parish.

What are the odds? Approval rates by type of work
Every decided application in this dataset, classified by the same type-of-work model used for the cost estimates above — so the grant rate for "Extension" is measured over exactly the applications this site costs as extensions. Withdrawn applications are counted separately rather than hidden in either number. Overall: 6,230 of 6,792 decided applications granted (92%).
| Type of work | Decided | Granted | Refused | Withdrawn | Median time to decision |

High grant rates partly reflect self-selection — applications unlikely to succeed are often never submitted, or are withdrawn after pre-application advice — so a 93% grant rate does not mean any conceivable proposal has a 93% chance. Time to decision is measured from the register's received date to its decision date.
