The tentacles of Artificial Intelligence (AI) are rapidly infiltrating very many areas of everyday life, with planning and development no exception.
Undoubtedly, AI can be seen as a positive and useful tool in the streamlining of complex workflows and managing of vast datasets to support those involved in the planning process, but it should be used with great caution, as outlined in the Planning Inspectorates Guidance (September 2024).
In practice, the use of AI in the world of planning is not without risk and can prove inaccurate.
It should be noted that it is now a requirement to declare the use of AI when submitting a planning application or appeal. Failure to declare this information can have significant adverse consequences.
We are keen to stress that AI should not replace the need for the nuanced expert knowledge and human judgement of an experienced chartered planning consultant for clients wishing to achieve the best outcomes when making planning submissions.
AI provides a tool to allow planners and developers to work collaboratively on live models of sites and projects. It can assist in highlighting potential constraints and possible opportunities for a proposed scheme. AI is also a very useful tool for providing summaries of lengthy documents, flagging risks, accelerating repetitive daily tasks and offering a platform for starting conversations with interested parties about a development scheme.
What it can’t do is provide an expert understanding of the local character of an area, the political context likely to influence decision making, the overall lived experience of a community and how planning policy is actually applied.
It is for these reasons that chartered planning consultants remain essential in interpreting evidence, shaping the narrative and exercising professional judgement and negotiations in order to deliver development through a ‘human lens’ that no algorithm is able to fully grasp.
Although AI has the ability to greatly assist planners in their daily tasks, the use of this tool comes with its own risks. By solely relying on AI to produce planning statements or supporting documents, the result could be reports that lack detailed intellectual rigour and use tests that rely on potentially ‘fake’ misinformation that do not address the key points that are individual to the specific characterising of a site.
The use of incorrect information generated by AI in the submission of planning applications and appeals could open applicants and appellants up to claims of unreasonable behaviour. Indeed, recent appeal decisions have indicated that the Planning Inspectorate has awarded cost decisions where planning statements have failed to address or acknowledge the use of AI in producing planning documentation.
It is for these reasons that the Planning Inspectorate's Guidance (referred to above) requires for all elements of AI used in planning application submissions to be declared in a short supporting statement. By declaring where AI has been used to inform a planning application or appeal, the decision maker is able to exercise their professional expertise and apply appropriate weight to the accuracy of information provided in order to come to a balanced and professional decision about the case.
It is evident that the future of planning will inevitably involve the use of AI. However, while AI can be used as a tool to accelerate mundane daily tasks and as a starting point for collaborative working, it is unable to replace the value and judgement of an experienced chartered planning consultant whose skill and expertise can combine the human element with professional knowledge.

I was extremely pleased by the service provided by Dan Foster at Salmon Planning Company. He provided advice in relation to securing planning approval for the conversion of a barn to a residential annexe, leading to a swift and successful outcome. His advice was timely, thorough and well reasoned and his effective communication with the planning authority led to an outcome which would not otherwise have been likely. The support provided proved to be money well spent.
I’ve been using Dan Foster and his team for over 2 years now on my property developments, the level of service, support, and professionalism of each member forever seems to impress! They have saved me many times, highlighting (potentially expensive) issues I had missed and always listen to my ideas and questions with great patience . I cannot recommend this company more highly , if you need reliable advice/designs from a team for your projects definitely give Salmon Planning a call. They will tell you everything in black and white and explain all you need to know regarding the complete planning process from start to finish.
Prompt, professional and client-focused. Would highly recommend Salmon Planning, thank you!
The Salmon Planning Team assisted me with an assessment of development potential in the Conservation Area of a rural Oxfordshire village. The advice I received was extremely helpful both in its decisiveness and clarity and backed up by a very useful written report. I would be happy to recommend the company for those looking for a very experienced and professional planning-led team. I wish I had contacted a planning-led architectural firm first off rather than having expensive plans drawn up by an architect and then refused by the Local Authority! It would have been a much cheaper exercise.
I regularly contact Nigel Salmon for information and advice. He, and his colleagues, are always friendly and rapidly provide excellent advice and services. As a Chartered Surveyor myself, I appreciate the professionalism of this firm.
It has been a real pleasure working with Matt and the team at Salmon Planning + Architecture. Throughout the process they have been consistently professional, prompt to respond, and genuinely helpful at every stage. A great team to work with, which I wouldn't hesitate to recommend.
Dan and the rest of his team at Salmon Planning were consumate professionals, dealing with every aspect of a sensitive, high profile, listed, town centre development, in a conservation area. Always available for every question I had … and I had a lot.I would, without a doubt ,call upon them for any future planning projects and would have no reservation whatsoever in recommending. Unquestionably 5 star - thank you.
I was very pleased with the services and advice provided by Salmon Planning. I also thought the in-house architecture / drawing service worked well - saving costs, time and generally making things far more efficient. We managed to easily secure consent for something that I thought might be fraught with issues. Nigel is also very well informed on local / Somerset matters. Highly recommend!
I have found Salmon Planning to be a well-run, professional planning company who have always strived to go above and beyond to help their clients achieve their objectives.I wouldn’t hesitate to recommend them to anyone.
Salmon Planning have secured planning permission for me for both holiday lodges and a new build pub and restaurant as well as for a new dwelling. The Salmon Planning team’s skill at handling complex planning applications and securing successful outcomes has been excellent. I would happily recommend their planning and architectural design teams.
We had the pleasure of working with Matt and Dan from Salmon planning recently. They dealt with our planning application for a wrap around kitchen extension from idea to submission. They listened and came up with very helpful input. They are a useful mix of knowledgeable, practical and creative. They made the process straightforward, seamless and enjoyable. They dealt with all the laborious paperwork and liaised with other relevant bodies, leaving us to just contribute to the ideas and design. They are both extremely amiable and a pleasure to deal with. The process was affordable and I feel I got great value for money. Use them, you will be pleased you did.
We worked with Dan and Matt at Salmon Planning Company to secure planning permission for a double garage, workshop, and gym/yoga room. From start to finish, they were incredibly professional, knowledgeable, and easy to work with. Their advice on both the planning and design stages was excellent, and they made the whole process smooth and stress-free. Highly recommend their services!
Excellent all round service from Nigel and his knowledgeable and experienced team. I have recommended them to many people in the past and will continue to do so in the future as they listen, understand and work with clients to deliver achievable results.
Excellent end-to-end experience and advice for our listed property in Brighton. Would highly recommend
