Westminster’s Environmental Supplementary Planning Document (ESPD) was adopted on 28 February 2022 and can be downloaded below.

Prior to adoption, the council consulted on the ESPD between 17 May 2021 and 28 June 2021. A Consultation Statement explaining how consultation comments were considered and an Equalities Impact Assessment were published alongside the Cabinet Member decision and can also be viewed on the Decision’s portal. 

The ESPD covers seven environment topics as follows – air quality, local environmental impacts, green infrastructure, flood risk, energy, waste management and retrofitting and sustainable design and provides -

  • an overview of the relevant planning policies; 
  • guidance on considerations when implementing environmental considerations into a development;
  • advice on development requirements and standards and the information you should submit if you're applying for planning permission. 

It should be read together with the council’s City Plan, Code of Construction Practice, Validation Checklist, Freight, Servicing and Deliveries Strategy and other SPDs.

The ESPD should also be read in conjunction with the following guidance that has been subsequently published by the Mayor of London. Where the guidance listed below supersedes an earlier version of the same document that is referred to in the ESPD, you should instead refer to the latest version listed below:
