Planning and the Climate Emergency
Our Climate Emergency Action Plan identifies that up to 86% of Westminster’s carbon emissions are produced from the energy used in our homes. To tackle the climate emergency, we need to take action to upgrade our homes so they are energy efficient and resilient to a changing climate.
There are many ways you can retrofit your home and introduce measures which will reduce your energy use. If you are already considering building an extension or undertaking other renovation works to your property, this provides a great opportunity to undertake other works to enhance the energy performance of your home.
These pages provide some advice for householders on common retrofit measures you may be considering and what permissions you will require. We will continue to update these pages to include advice on a wider range of measures.
Will I need planning permission?
This will depend on the type of property (flat or house), the details of the proposals and site location.
Generally, internal changes will not require our permission, unless the proposals relate to a listed building. See ‘quick wins’ below for examples of measures you can consider straight away, without making an application. External measures such as solar panels, air-source heat pumps and new more thermally efficient windows need planning permission in certain locations and if certain criteria are not met.
If you are in a conservation area or an article 4 property it is more likely you will need to make an application or adhere to certain conditions. If your project is to a listed building then typically it will need our permission, including for internal alterations.
The pages below provide advice on some commonly proposed measures. Before you read this you should check if you are:
- in a conservation area
- in a listed building
- in an article 4 property (there are 8 areas where we restrict minor alterations in conservation areas)
How can I make an application?
If permission is required, you can make your application online via the planning portal.
Read more about how to make an application and the information you need to submit.
How can I get help?
To help householders take action on the climate emergency, we now offer a discounted rate of planning preapplication advice for residents who wish to make environmental improvements to their properties including listed buildings. This applies to changes to windows, installation of heat pumps, green walls and solar panels in flats and single houses.
A planning officer can give more detailed site specific advice about whether your proposal is likely to be acceptable through our pre-application advice service.
