Clause 18

An applicant for planning permission or conservation permission may if he so desires apply in the first instance for outline permission in the manner prescribed.

An application for outline permission shall be determined on the same basis as an application for planning permission or conservation permission except that the competent authority shall have regard only to matters relating to land use, intensity, type, form and height of the proposed development or works.

Outline permission shall constitute approval in principle for the proposed development or works, but shall not authorise the carrying out of that development or works or any other development or works.

Any grant of outline permission shall lapse 6 months following the date of its granting unless a longer period is specified in the outline permission or the competent authority otherwise directs in writing.

Where subsequent to the grant of outline permission an application for planning permission or conservation permission is made during the validity period of the outline permission, the application shall be determined on the basis of the further details supplied on that subsequent application.

Section 22 shall apply, with the necessary modifications, to applications made under this section as it applies to applications made under section 13.
