PLANNING SERIES:

  • Scottish Planning Policies (SPPs) provide statements of Scottish Executive policy on nationally important land use and other planning matters, supported where appropriate by a locational framework.
  • Circulars which also provide statements of Scottish Executive policy, contain guidance on policy implementation through legislative or procedural change.
  • Planning Advice Notes (PANs) provide advice on good practice and other relevant information.

Statements of Scottish Executive policy contained in SPPs and Circulars may be material considerations to be taken into account in development plan preparation and development control.

Existing National Planning Policy Guidelines (NPPGs) have continued relevance to decision making, until such time as they are replaced by a SPP. The term SPP should be interpreted as including NPPGs.

Statements of Scottish Executive location-specific planning policy, for example the West Edinburgh Planning Framework, have the same status in decision making as SPPs.
