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.

This application sits outside the common categories, which can include county matters such as minerals and waste, works by statutory undertakers, demolition notifications and other less frequent procedures. The council record linked below sets out the specific procedure that applies, and the description above is taken directly from the published register.
