Supplementary Planning Documents and Guidance

Find out about our Supplementary Planning Documents and Guidance

These pages provide planning guidance that complements policy contained within Westminster's Development Plan. They are intended to assist those wishing to prepare and submit planning applications in Westminster. 

Guidance documents on this page have either been adopted as Supplementary Planning Documents (SPDs) or Supplementary Planning Guidance (SPGs) and are  material considerations when assessing planning applications in Westminster. These documents do not introduce new policies and therefore do not have  the same status as the policies within Westminster's Development Plan.

Following adoption of City Plan 2019-2040 in April 2021, the council is working on new SPDs that will provide updated guidance on how to implement policies in both the new City Plan 2019-2040 and new London Plan 2021. Since April 2021, the council has adopted one new SPD – the Environment SPD. A full schedule of the SPDs the council is working on at the moment, can be found in our Local Development Scheme. A number of older SPDs and SPGs will still remain relevant until any new guidance is produced, and are therefore also included here for completeness.   

On these pages you can find:  

Other informal guidance documents that have not been formally adopted as SPDs or SPGs, but can still be a material consideration, can be found in the Other Planning Guidance webpage. Documents in the Evidence and Monitoring webpages also provide background information that may be helpful to applicants.
