   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.

Advertisement consent controls signs, hoardings and other adverts. The council may only judge two things: amenity, meaning the effect on the appearance of the building and area, and public safety, chiefly whether a sign distracts road users or obstructs sight lines. Other planning considerations, such as competition between businesses, do not apply.
