Wiltshire’s long-running Local Plan Review has reached a critical moment. In a letter issued on 2 March 2026, the Inspectors examining the Plan concluded that the Council faces a stark choice: withdraw the Plan or continue the Examination knowing it will likely be found unsound.
The Inspectors’ concerns centre on fundamental issues including insufficient housing allocations, uncertainty around the delivery of a proposed new community at Salisbury, and a timetable that would see adoption of the Plan pushed back to around 2028, leaving it with a lifespan of less than ten years. Against the backdrop of significant national planning reform and Wiltshire’s existing housing land supply shortfall, the Inspectors’ conclusion is clear: the Plan has effectively run out of time.
For landowners, developers and promoters operating in the county, the implications are significant. With the current Core Strategy period ending this year and no replacement plan in place, the policy vacuum is likely to open the door to increased speculative development proposals as the Council seeks to address a serious housing land supply deficit.
Wiltshire’s Local Plan Review – the story so far
For those with development interests in Wiltshire, Monday 2 March 2026 marks the latest episode in the Local Plan Review process, with the publication of a letter from Inspectors.
Essentially, the Inspectors presented the Council with an unenviable choice:
- Withdraw the Plan, or
- Have the Inspectors find that the Plan is unsound.
We have been involved in the Local Plan and the Examination in Public (EiP), promoting land for development. For those with land interests in the County and not familiar with the Local Plan process, the Wiltshire Plan has had a troubled development period, and the Examination has not exactly run smoothly. However, it culminated with the Inspectors writing to the Council in December 2025, setting out serious concerns about the Plan and seeking a response from the Council ascertaining what it was going to do to solve them.
To the Council’s credit, an action plan was promptly published at the end of January, outlining what the Council proposed. In effect, if the Council’s timetable was to be believed, all the necessary technical work for a Plan ending in 2038, could be wrapped up by the autumn of 2026. This, in turn, would allow the Examination to reopen before the end of 2026.
Unfortunately, the Inspectors are not convinced. The time estimate for concluding the technical work is too optimistic and would not see a Plan being adopted until early 2028 at the earliest, leaving a Plan period of less than 10 years.
The key issues: housing supply and time
At this stage, there is no need to dive into the forensic detail of it all. The Inspector’s letter is clear, but the key issues can be summarised in not allocating enough land, question marks over the delivery of a new community in Sailsbury, culminating in a Plan, which will have a shelf-life of just over 10 years from adoption. When this is added to the Government’s reform of the Local Plan system, launching this year, the conclusion is stark: the Inspectors have concluded that the Council has simply run out of time and, unlike Marty McFly, there is no DeLorean to allow them to revisit earlier mistakes.
Wiltshire’s housing land supply challenge
So, what does this all mean?
Like many LPAs, Wiltshire had a serious housing land supply problem going into the Examination and this is compounded by the NPPF revisions in December 2024. Currently, the Council’s own figures present a five-year supply figure of 2.42 years. Matters are amplified even more by the Plan period of the current Core Strategy, which expires this year. Given the failure of the Plan, the Council no longer has a Plan in place to resolve this undersupply.
Again, this raises the inevitable question of “speculative development” coming forward, and it is a simple, obvious fact that sites will be coming forward to meet its housing land supply requirements. While some will deride this, it has to be remembered that these sites will provide homes for all, including much-needed affordable housing. They will also create jobs and support local services and facilities. Housebuilding is a good thing. It also must be remembered that this is not just limited to housebuilding; employment development can also be viewed through a positive lens.
Wiltshire has a well-understood settlement hierarchy and makes extensive use of settlement boundaries. Neighbourhood Planning is also prevalent in the County, with several Parish Councils producing Plans which allocate housing sites (some of which we have secured).
Opportunities for landowners and the SME Housebuilding Sector
The current situation also represents a huge opportunity for the SME Housebuilding Sector. Now is the time to look seriously at smaller sites that can come forward and be delivered within five years. In looking at sites to come forward, I cannot stress enough that it’s a question of doing the basics right, ensuring the site is in a sensible location, deliverable, and free of genuine constraints. Writing this article in March, we are on the cusp of ecological survey season, so speculative applications this year are a realistic possibility. Also, given the sheer size of the County, I would recommend that very careful attention is given to the sustainability credentials of a site, in terms of accessibility to services and facilities, not just in the settlement concerned, but also to major centres elsewhere in the County.
What next for planning and development in Wiltshire
The Inspectors’ latest letter effectively places Wiltshire’s Local Plan Review at a crossroads. Whether the Council ultimately withdraws the Plan or continues the Examination, the underlying issues remain the same: the county faces a significant housing land supply shortfall, and the current development plan framework is approaching the end of its life.
In the short to medium term, this creates a very different planning landscape. Without an adopted revised plan in place, and with national policy continuing to place strong emphasis on housing delivery, it is inevitable that new sites will come forward to help address the shortfall. While often labelled “speculative”, such development plays an important role in delivering homes, including affordable housing, supporting economic growth and sustaining local services.
How we can help you with your development aspirations in Wiltshire
For landowners and developers, the key will be identifying sites that are genuinely deliverable and well located in sustainability terms. Smaller sites capable of coming forward quickly – particularly those suited to SME housebuilders – may be especially well placed in the current context.
As ever, success will depend on careful site assessment, robust planning strategy and a clear understanding of the local policy landscape. With the right approach, the current uncertainty in Wiltshire’s plan-making process may present a real opportunity for landowners and developers to bring forward sustainable development.
Having recently secured permission on both allocated and unallocated sites in the County, we can advise you on how to make the most of the opportunity this presents.
