Planning in Wales is devolved to the Senedd Cymru (Welsh Parliament) and as a result, the planning system is different from that operating in England. The most notable differences are in National Guidance, Planning Policy Wales 11 (PPW), the Technical advice notes (TANs) and the development plan system (LDPs).
A further key difference is the two tier system of governance as in Wales all authorities are unitary. There are 22 unitary authorities and 3 National Parks.
