Southampton City Council has restarted preparation of its Local Plan under England’s new 2026 plan-making system, with a live scoping consultation running from 7th September to 11th October 2026.
The council had already consulted on emerging proposals in 2020 and 2022. Those earlier responses are not being discarded. Southampton says they remain part of the evidence base and have helped shape the questions being asked during the new scoping consultation.
The council has also published a full timetable through to intended adoption on 21st March 2029, with Gateway 1 currently scheduled for 30th October 2026.
Southampton Local Plan consultation is now live
Southampton announced the launch on 7th September 2026. The first consultation under the new system is a scoping consultation, rather than a consultation on a finished draft plan or a list of final site allocations.
The council says this stage is intended to test the broad issues and priorities the Local Plan should address and to find out how residents, businesses, community groups and other stakeholders want to be involved as the plan develops.
Alongside the Local Plan consultation, Southampton is also running a Strategic Environmental Assessment scoping consultation and a final call for potential development sites. Together, these are intended to help build the evidence base for the next stages of plan preparation.
You can take part through Southampton City Council’s Local Plan consultation page.
Earlier consultation work is being carried forward
One of the more useful points in Southampton’s announcement is what happens to the work already done under the previous plan-making process.
The council consulted on emerging Local Plan proposals in 2020 and 2022. It says those responses remain relevant and will continue to form part of the evidence base for the restarted plan.
Southampton also says the earlier feedback has helped shape the questions now being asked. The new consultation therefore resets the statutory process without pretending that several years of evidence and public engagement never happened.
Our analysis: that distinction is important for anyone who responded previously. A procedural restart does not necessarily mean earlier evidence or representations become worthless. But the current scoping consultation is still a fresh opportunity to say whether the issues and priorities identified previously remain right and whether anything new has emerged.
Gateway 1 is scheduled for 30th October 2026
Southampton’s current Local Plan timetable lists Gateway 1 for 30th October 2026.
Gateway 1 is the council’s self-assessment stage under the Town and Country Planning (Local Planning) (England) Regulations 2026. It is not the independent examination of the Local Plan.
Our main Local Plans guide explains the new gateway system and how it differs from the former plan-making process.
Southampton’s timetable runs to March 2029
The council says its timetable will be reviewed monthly and updated where necessary. The current programme is:
- Notice of intention: published 26th June 2026
- Scoping consultation: 7th September to 11th October 2026
- Gateway 1: 30th October 2026
- Content and evidence consultation: 1st March to 18th April 2027
- Gateway 2: 6th December 2027
- Proposed Local Plan consultation: 3rd April to 4th June 2028
- Gateway 3: 31st July 2028
- Submission for independent examination: 11th September 2028
- Target adoption: 21st March 2029
This provides a useful real-world example of the sequence introduced by the 2026 Regulations: scoping, Gateway 1, content and evidence work, Gateway 2, the proposed plan, Gateway 3, submission, examination and adoption.
Three formal consultations are planned
Southampton describes the current scoping exercise as the first of three formal consultations.
The second, currently planned for March and April 2027, will deal with proposed plan content and supporting evidence. The third, currently planned for April to June 2028, will be the consultation on the proposed Local Plan itself.
That means the September 2026 consultation should not be mistaken for the last chance to comment on detailed policies or development sites. It is the opening statutory stage under the new system.
Why this matters for residents and landowners
For residents and community groups, the immediate question is whether Southampton is asking the right questions about the city’s future and whether the engagement process will give people a practical way to participate.
For landowners and developers, the accompanying final call for potential development sites is also important. Anyone promoting land should follow the council’s current submission requirements rather than assume an earlier representation will automatically cover everything needed under the restarted process.
The Local Plan will eventually become part of the city’s development plan and help guide future planning decisions.
The Planning Geek takeaway
Southampton is a useful live example of what restarting a Local Plan under the 2026 system looks like in practice.
The statutory process has restarted, but earlier consultation work is being carried forward. The council has now opened the scoping stage, set Gateway 1 for 30th October 2026 and published a programme running through to intended adoption in March 2029.
The immediate deadline is 11th October 2026. Anyone who took part in the 2020 or 2022 consultations should not assume that previous comments mean there is nothing useful to say now.
