Alongside the Bill
To incentivise plan production further and ensure that newly produced plans are not undermined, our intention is to remove the requirement for authorities to maintain a rolling five-year supply of deliverable land for housing, where their plan is up to date, i.e., adopted within the past five years.

“The government’s three areas proposal
Recommendation:
The Government should reconsider the case for the three areas proposal. Any new proposals can be considered in detail if the Planning Bill is published in draft form and we undertake pre-legislative scrutiny, as we recommend. (Paragraph 32)
Response:
8. The Government agrees with the recommendation of the Committee and will not be pursuing three area types in the reformed planning system. The Government have listened carefully to feedback from the consultation, sector stakeholders, the public and other interested parties.”
