Counts are read from planning.data.gov.uk and refreshed daily. A zero or dash means the council has not yet published that dataset to the national index — not that the designation doesn’t exist on the ground. We show what we found and tell you what we didn’t. We never infer a restriction — or the absence of one — from missing data.

Reading Southwark’s planning landscape
With 56 conservation areas on the official index, design and character carry real weight in Southwark decisions. Inside a conservation area the bar for external alterations rises, and some permitted development rights narrow — which side of a boundary your property sits on can change your project’s planning route entirely.

London Borough of Southwark has 480 Article 4 direction areas in force. An Article 4 direction removes specific permitted development rights, so work that would normally need no application — certain extensions, alterations, even paving — can require full permission. This is the single most common surprise we find for homeowners, and it is address-specific.
Every application in Southwark is decided against national policy (the NPPF), the London Plan, and London Borough of Southwark’s adopted Local Plan. A Planning Policy report quotes the specific policies that apply to your project — verbatim, verified, and linked to the official documents.
