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. This will curb perceived ‘speculative development’ and ‘planning by appeal’, so long as plans are kept up to date. We will consult on changes to be made to the National Planning Policy Framework.
