When is it required?
For planning applications in England, the national requirement covers major development and certain development in a conservation area or World Heritage Site: provision of one or more dwellings, or a building or buildings creating at least 100 square metres of floorspace. Being in a conservation area does not, by itself, mean every householder proposal needs a statutory Design & Access Statement. [2]
There are exceptions, including applications relating solely to a material change of use, engineering or mining operations, waste development, and applications under section 73. Listed building consent has its own statement requirement; the access element is not required where the works only affect the building's interior. Check the application route, not just the project description. [1]
What should the document explain?
The statement should show the design thinking rather than simply describe the drawings. Explain the site and surrounding character, the design principles, how the context influenced the proposal, and the approach to access. Where relevant, explain consultation about access and how specific access issues have been addressed. Its length should reflect the proposal's complexity. [1]
A useful way to brief its author is to ask:
- Which characteristics of the existing building or street are being retained or changed?
- Why were this layout, scale and appearance chosen?
- How will people reach and enter the development, and which constraints have affected the solution?
Use annotated plans and photographs to answer these questions directly. Avoid adding pages of unrelated policy quotations merely to make the statement look substantial.
Who prepares it?
The project designer is usually well placed to explain the design, with a planning consultant helping where policy issues are complex. Ask heritage or access specialists to contribute where the proposal depends on their expertise. The national guidance focuses on the information required; it does not make a particular professional title a universal prerequisite for writing the document. [1]
For a listed building, a coordinated Design & Access Statement and heritage assessment can avoid duplication, provided the combined document actually addresses significance and the effects of the proposed work. Clearly label the separate subjects. [3]
Check the current submission requirements
The NPPF published on 17 August 2026 uses policy DM2 to require proportionate, relevant application information. Read national requirements alongside the council's current validation list: a local request for additional design evidence should not be confused with the statutory Design & Access Statement trigger. [4]
Before submission, check that the statement names the same proposal and drawing revisions as the application. Where the design has changed during preparation, remove explanations of abandoned options unless they are deliberately included to explain how the final solution was reached.
