How it is counted
- A neighbourhood is a CSO electoral division; its households and population are the 2022 census totals of the small areas inside it. Every application, appeal and commencement notice is placed in the division its point falls in.
- Household works are applications whose description says extension, attic, dormer, porch, garden room, garage conversion and the like, and does not say apartments, units, commercial, retail or office.
- Retention is an application whose type or description says retention — permission for something already built. Its grant rate is shown where at least ten were decided.
- Decisions count grants and refusals only; invalid, withdrawn and undecided applications are left out of every rate. Days are from the council’s receipt date to its decision date.
- A rate is printed only where the neighbourhood has at least 20 of the thing being rated in the window; smaller ones show counts and are not ranked.
