   Decision issued: PRIOR APPROVAL NEEDED AND GRANTED

3. 12 Aug 2026

   Added to PlanIndex

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.

Prior approval applications arise where permitted development rights already grant the principle of the work, such as larger home extensions, changes of use to housing or agricultural buildings. The council may only consider the specific matters set out in the rules, for example transport, flooding or appearance, and in many classes the work may proceed if the council does not respond within the deadline, commonly 56 days.
