A design and access statement explains the thinking behind a scheme — how the design responds to its context and how people will reach and use the building. It is legally required only for major development, listed building consent and development in conservation areas or World Heritage Sites, but it is frequently useful beyond that.
Statutorily, a design and access statement is required for applications for listed building consent, and for major development or development in a conservation area or World Heritage Site. Householder applications outside those categories do not legally need one, though many boroughs ask for a short statement on their local validation list.
Where it is required and missing, the application is invalid — it does not start the eight-week clock until it is supplied.
Four things, briefly: the context, including the character of the street and the conservation area appraisal if there is one; the design response, covering amount, layout, scale, landscaping and appearance; the access arrangements; and the justification for anything that departs from local policy or guidance.
Length is not the point. A precise two pages that engage with the borough's own design guidance does more than ten pages of generic description.
It gives the case officer the reasoning to put in their report. Where a scheme exceeds a guidance depth or sits at an awkward roof junction, the statement is where the reasoning is set out — that the depth matches an existing neighbouring extension, or that the roof form follows the prevailing pattern identified in the conservation area appraisal.
How design and access statement plays out in Waltham Forest: London Borough of Waltham Forest (Waltham Forest Council) maintains 17 conservation areas, the Walthamstow Village Conservation Area and the Lloyd Park Conservation Area among them, and an Article 4 direction is in force there, so permitted development cannot be assumed. Anyone dealing with design and access statement at a Waltham Forest address is therefore working to a £548 householder application decided in 8 weeks, or a £249 prior approval over 6 weeks where design and access statement still qualifies.

The designer. It should reflect the drawings, not restate them.
Street and context photographs are usually the most persuasive part.
