Portsmouth councillors will vote next week on whether to start work on a new planning blueprint that would shape development in the city until late into the next decade. The full council meets on 14 July 2026 to consider formally commencing the Future Portsmouth Plan, a document prepared under new national regulations designed to streamline how councils set out their long-term planning policies.
If approved, the plan would run on a tight 30‑month timetable aiming for adoption in April 2029. The first formal milestone, Gateway 1, falls in November 2026, with two further checkpoints in December 2027 and July 2028 before submission to the Planning Inspectorate a month later. The council has already received £108,474 from the Ministry of Housing, Communities and Local Government in March 2026 to support the early stages, a grant intended to help local authorities move onto the reformed system introduced by the Levelling Up and Regeneration Act 2023.
Work on the Future Portsmouth Plan will run alongside the existing Portsmouth Local Plan, which is currently being examined by three government‑appointed inspectors. That plan, covering the period up to 2040, drew more than 6,000 comments during public consultations in 2024 and 2025 and is expected to be adopted in 2027. On 19 June the inspectors T. Parton, D. McCreery, and M. Philpott put initial questions to the council, keeping the examination on track. Starting the new plan early is seen as a way to reassure developers and residents of the council’s commitment to plan‑led growth, especially while the older plan’s examination unpacks complex issues such as the environmental balancing test at Tipner West.
The timetable is shadowed by wider structural changes facing Hampshire. Local government reorganisation will create a new South East Hampshire unitary authority from April 2028, three months before Gateway 3, raising a question over whether the incoming body would adopt the plan or restart it. At the same time, the new Hampshire and Solent Mayoral Combined County Authority launches this month and may eventually require any local plan to pass a conformity check against a future regional spatial strategy. The report to council acknowledges that while these risks are real, delay would itself be a risk, leaving planning decisions unmoored from an up‑to‑date framework.
The Future Portsmouth Plan is aligned with the council’s Corporate Plan 2024‑2026 and the Imagine Portsmouth 2040 Vision. Two scoping consultations and a call for sites are pencilled in for this summer before the official countdown begins in November.
