Advice on planning application supporting documents

Guidelines on content of supporting documents which may be required with your application such as heritage and fire statements.

Heritage statements

Our local validation requirements require a heritage statement with applications where a heritage asset or its setting is affected. This will include all applications for development or works to a listed building, development in conservation areas, registered parks and gardens and the Westminster World Heritage Site or development affecting their settings. For less complex cases this may form a section within the Design and Access Statement.

Our heritage statement template provides a guide to our requirements.

Historic England have prepared advice on analysing heritage significance.

There is a separate requirement for an archaeological assessment for development affecting Archaeological Priority Areas.

World Heritage Site

If your application has the potential to impact on the Outstanding Universal Value of Westminster World Heritage Site, in addition to your design and access statement, our local validations requirements require a Heritage Impact Assessment prepared in line with the ICOMOS HIA Guidance and as set out in our guidance on HIA.
