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. It doesn’t mean 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 Barnet’s planning landscape
With 16 conservation areas on the official index, design and character carry real weight in Barnet 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. Browse Barnet’s conservation areas →
London Borough of Barnet has 48 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 Barnet is decided against national policy (the NPPF), the London Plan, and London Borough of Barnet’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.
