Outline planning applications are used to establish whether the principle and main elements of a proposed development are acceptable. Less information is required for an outline, compared to a full application. Outline applications are often used for larger schemes, such as a new housing development, or when the applicant wants to sell the site on and not develop it themselves. Applicants may also choose to submit an outline application where there is uncertainty about whether the proposal will be successful.
Outline planning permission can only be granted subject to conditions requiring the subsequent approval of one or more ‘reserved matters’, by way of a reserved matters application.
