Following a period of consultation, the Welsh Government has confirmed that it will revise Planning Policy Wales (PPW) by implementing the replacement of the five-year housing land supply policy by the monitoring of housing delivery against local development plan housing trajectories. This will involve the revocation of TAN 1 (Joint Housing Land Availability Studies) and the publication of Edition 3 of the Development Plans Manual. These changes will be incorporated in a new edition of PPW in the autumn of 2020.
