Heritage planning in Islington covers applications for listed building consent, conservation area development and works affecting heritage settings, governed by Islington Council's local plan and a wide network of conservation area design guidelines.
Islington has more than 40 conservation areas and a dense concentration of Georgian and early Victorian terraces, Canonbury, Barnsbury, Highbury Fields, Clerkenwell and Duncan Terrace among them. The borough applies one of London's stricter regimes on basements, windows, shopfronts and rear extensions, with detailed conservation area design guidelines that set out the expected standards for each character area. Successful applications depend on close engagement with these guidelines and a clear evidence base.

The borough enforces these directions actively and expects strict adherence to the relevant conservation area design guideline.

“Islington's conservation team is exacting on original joinery. Vestige set out the case for the reinstatement scheme so clearly that the officer's report largely repeated our wording, and approval came inside seven weeks.”
