Information on environmental impact for everyone who lives in or manages a building in the city.

Westminster environment guidance

Environment friendly icon

These pages provide a one-stop shop to help you reduce the environmental impact of the buildings you plan to build, extend or refurbish, as well as those you currently spend time in.

These resources are useful to everyone who lives in or manages a building in the city.

Sustainability is rapidly evolving and we will be updating this page regularly to reflect changes in guidance and the law.

The guidance

This guidance does not hold any statutory weight in decision making. It signposts to material consideration, particularly if it is referenced within the adopted local plan and is therefore expected to be complied with policy. Our development plan is currently made up of:

  • City Plan (2019-2040)
  • London Plan
  • Knightsbridge Neighbourhood Plan (2018)
  • Mayfair Neighbourhood Plan (2019)

Both the City Plan and London Plan are now adopted. Three neighbourhood plans are also currently undergoing examination (Fitzrovia West, Soho and Queen’s Park) and will likely be adopted later this year. Our new Environmental Supplementary Planning Document (ESPD) is also open to public consultation from 17 May to 28 June. This guidance will be updated once new plans come into force.

Westminster has declared a climate emergency – our commitment to becoming a carbon neutral council by 2030 and carbon neutral city by 2040.

Why this matters

Environment icon

Harmful greenhouse gases such as carbon dioxide (CO2) trap heat in the atmosphere and cause extreme global temperatures that impact us all.

Smart City innovation icon

If everyone works together, we can avoid the worst impacts of climate change and build the city’s resilience to these changes.

Building icon

Westminster has some of the highest carbon emissions in the UK, most of this is generated from the energy used to heat and power buildings.

Our guidance offers an insight into concepts that are beginning to be understood outside of a technical setting.
