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 three 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 amendments applications

How this application type works

An amendment application changes a permission that already exists. Non-material amendments cover small adjustments with no wider effect, while minor material amendments, usually made by varying a condition, allow modest design changes without a fresh application. Anything beyond that needs a new permission, so the scope here is deliberately narrow.

  • 24/00824/NMA Awaiting decision

    Calderdale College Francis Street Halifax Calderdale HX1 3UZ

    Non material amendment to application 24/00824/FUL; extend temporary period on condition 3 and 4 this usage & lighting time extension was given with the idea that the works would be completed by July 2025 and 12 months would be enough time to understand any concerns from neighboring households or businesses. Unfortunately, due to a delay with the project, the work will only be completed on 31st July 2026 and this will give us no time to trial the time extension as the deadline for the trial has already passed. our proposal is that another 12 month period is granted up until 31st July 2027. All other conditions of the approval will remain, just points 3 & 4 will be changed to grant the additional hour Monday - Friday.
