Data transparency

Rankings are compiled from approved planning applications recorded against City of London Corporation 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 We do not publish approval rates, because refused applications are not in our source data.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 City of London Corporation. Think our data is wrong? Contact us and we'll correct it.
