New National Planning Policy Framework published
The Government published the new National Planning Policy Framework (NPPF) on 17 August 2026. It came into effect on the same day. This means that planning decisions will need to take it into account immediately. The new NPPF is split into two sets of planning policies:
one set to help Cornwall Council write the next local plan, and
the other to be used in planning decision making.
This is the Government’s summary: Creating a clear, rules-based planning system - GOV.UK.
You can find more information on our Planning Changes webpage. Our Planning Explained webpage sets out how these changes affect planning decisions in Cornwall.
