Westminster's Environment Supplementary Planning Document

Westminster City Council has adopted a new Environment Supplementary Planning Document. This follows formal consultation in May – June 2021 and the adoption of Westminster’s new City Plan in April 2021.

The SPD is a wide-ranging document, providing much of the necessary detail to support the formal policies within the new plan. It forms an important additional layer of guidance for developers and occupiers considering development or changes of use in Westminster, effectively restating and replacing much of the detailed policy that was previously contained within Part 2 of the old Unitary Development Plan, which finally ceased to apply on adoption of the new Plan. The Guidance specifically seeks to give “more prominence and weight to environment issues” and provides helpful additional detail on potential retrofit interventions.
