Scotland's Fourth National Planning Framework (NPF4) was formally adopted on 13 February 2023 by Scottish Ministers. This replaces NPF3 and Scottish Planning Policy. The NPF4 contains Scotland's long term strategy to 2045. The Planning (Scotland) Act 2019 removed the need for the preparation of Strategic Development Plans meaning all national policy, strategy and guidance, including timescales for delivery of national developments, is now contained within the NPF4.
