What happens while it is decided
The process from here
This application is with Westminster for determination. The council publicises it, consults neighbours and technical bodies where required, and weighs the responses against local and national planning policy.
The statutory target is eight weeks for most applications and thirteen for major development, though extensions of time are common. Comments carry most weight while the case is undecided, so check the council portal for the deadline if you want to respond.
About advertising applications
How this application type works
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.
