Before you build
Know what you can actually get approved at your address.
A feasibility study pulls the real planning decisions on and around your street: what was approved, what was refused, and why, then the most likely route to a yes.

Data transparency

Rankings are compiled from approved planning applications recorded against Southwark Council over roughly three years of public planning records. Counts reflect applications where the practice is named as agent; practices that rebranded or file under multiple names may be under-counted. We show approval counts only. We do not publish approval rates, because refused applications are not in our source data. This is an independent analysis and is not endorsed by Southwark Council. Think our data is wrong? Contact us and we'll correct it.
