What a grant of permission means

The process from here

Permission has been granted, usually subject to conditions listed on the decision notice, some of which must be discharged before work starts. The decision notice on the council portal sets out exactly what was approved.

Work must normally begin within five years of the decision or the permission lapses. Neighbours cannot appeal a grant; challenging one means judicial review of how the decision was made, within tight time limits.

About reserved matters applications

How this application type works

A reserved matters application fills in the detail held back from an earlier outline permission, typically appearance, landscaping, layout, scale or access. The council judges it against the outline permission already granted, not the principle of development, which is settled. It must normally be submitted within three years of the outline decision.
