Why a devolved application needs a different policy base
An English policy base does not transfer to Wales, Scotland or Northern Ireland. The plan hierarchy, the statutory duties, the flood framework and the terminology all change.
An AI-drafted planning document grounded in the National Planning Policy Framework is wrong in Wales, Scotland and Northern Ireland, and it is wrong in a way that is hard to spot. The structure survives the border. The policy tests do not. Planning Policy Wales, National Planning Framework 4 and the Strategic Planning Policy Statement for Northern Ireland each set up a different hierarchy, different statutory duties and different terminology, so an AI draft devolved planning policy exercise is a substitution job rather than a find and replace.
PlanScope's drafting is grounded in English national policy, English local plans and English procedure. For a devolved application the reviewer has to replace the policy base, and that is stated plainly rather than glossed over.
Why England-grounded drafting does not transfer
The obvious part is citation. An English draft will reach for the Framework, for Planning Practice Guidance chapters, and for development plan policies written to an English local plan structure. None of those are the right authority in Cardiff, Inverness or Omagh.
The less obvious part is the shape of the argument. English practice is built around section 38(6) of the Planning and Compulsory Purchase Act 2004, the presumption in favour of sustainable development, and a Framework that is a material consideration rather than part of the development plan. In Scotland, National Planning Framework 4 forms part of the development plan itself, which changes the weight it carries and the way a policy conflict is resolved. That single structural difference rewrites the balancing section of any planning statement.
Then there are duties that have no English equivalent at all. The Well-being of Future Generations (Wales) Act 2015 imposes a duty on public bodies that feeds directly into decision-taking in Wales. A draft that does not engage it has missed something a Welsh planning officer will expect to see addressed, and the point is developed in the well-being duty in Welsh planning decisions.
The Welsh policy framework in outline
The development plan in Wales consists of Future Wales: The National Plan 2040 at national level, any Strategic Development Plan, and the Local Development Plan for the area. Planning Policy Wales, currently in its twelfth edition, sets national planning policy and is supported by Technical Advice Notes rather than by a guidance portal.
Several Technical Advice Notes do work that has no direct English counterpart. TAN 15 governs development and flood risk, with its own acceptability framework and its own maps, which is not the Environment Agency Flood Zone system. TAN 12 covers design. TAN 5 covers nature conservation and planning. A flood risk case argued on English Flood Zone 2 and 3 terminology and the English sequential and exception tests will not engage the Welsh framework at all.
Placemaking is the organising idea in Planning Policy Wales, and the sustainable placemaking outcomes run through the policy chapters. Pre-application consultation is a statutory requirement for major development in Wales, carried out by the applicant before submission, which is a procedural step with no English equivalent. Biodiversity is handled through the section 6 duty in the Environment (Wales) Act 2016 and a net benefit approach rather than through the English statutory metric, which is covered in biodiversity duties in Wales and the absence of a net gain requirement. The relationship between Future Wales and an individual site is set out in how Future Wales applies to your site.
The Scottish framework in outline
Scottish planning runs on the Town and Country Planning (Scotland) Act 1997 as amended, most recently and substantially by the Planning (Scotland) Act 2019. National Planning Framework 4 was adopted in February 2023 and sits within the development plan alongside the Local Development Plan.
NPF4 policies are numbered and thematic. They cover climate change, biodiversity, quality homes, local living and infrastructure first, among others, and several of them are framed as policies that development proposals will or will not be supported against. The biodiversity policy expects enhancement rather than merely avoidance of harm, and it applies without the English thresholds and exemptions.
Procedure differs in ways that matter to a drafter. Scotland uses planning permission in principle rather than outline permission. Pre-application consultation is a statutory requirement for major and national developments. Use classes come from the Town and Country Planning (Use Classes) (Scotland) Order 1997, which has numbered classes and nothing resembling the broad English Class E, so a change of use argument written for Class E flexibility is meaningless. Permitted development comes from the Scottish order of 1992 as amended, with different classes and different limits. There is no Community Infrastructure Levy, and the lawfulness route is a certificate of lawfulness rather than a lawful development certificate.
The Northern Ireland framework in outline
Northern Ireland planning sits under the Planning Act (Northern Ireland) 2011, with eleven councils as planning authorities since the 2015 reform and the Department for Infrastructure dealing with regionally significant applications.
The Strategic Planning Policy Statement for Northern Ireland, published in 2015, is the overarching policy document. Alongside it, a set of retained Planning Policy Statements continues to apply in each council area until that council's Local Development Plan is adopted, and the adoption position varies between councils. That transitional arrangement is the single most common error in devolved drafting, because a document that cites only the Strategic Planning Policy Statement will have missed the detailed policy that actually decides the case.
Local Development Plans in Northern Ireland come in two parts, a Plan Strategy and a Local Policies Plan, adopted at different times. Development management practice notes published by the Department fill the role that Planning Practice Guidance fills in England. There is no Community Infrastructure Levy, and developer contributions are handled through planning agreements under the 2011 Act.
Terminology differences that matter
| England | Wales | Scotland | Northern Ireland |
|---|---|---|---|
| Local plan | Local Development Plan | Local Development Plan | Plan Strategy and Local Policies Plan |
| NPPF, a material consideration | Planning Policy Wales and TANs | NPF4, part of the development plan | Strategic Planning Policy Statement and retained PPSs |
| Outline permission | Outline permission | Planning permission in principle | Outline permission |
| Lawful development certificate | Lawful development certificate | Certificate of lawfulness | Certificate of lawful use or development |
| Community Infrastructure Levy | No CIL | No CIL | No CIL |
| Use Classes Order 1987, Class E | Use Classes Order 1987 as applied in Wales | Use Classes (Scotland) Order 1997 | Planning (Use Classes) Order (NI) 2015 |
Getting a term wrong is more damaging than it looks. An officer reading a statement that refers to the local plan and the Framework in a Scottish application will reasonably conclude the author has not read NPF4, and will weight the rest of the document accordingly.
What the reviewer must replace
Working through a draft prepared on an English policy base, the reviewer has to change five things rather than one.
- The national policy citations, replaced with the correct framework and edition, cited by its own numbering.
- The development plan section, rewritten to the correct plan hierarchy, including whether the national document forms part of the plan.
- The statutory duties engaged, adding the well-being duty in Wales or the relevant biodiversity duty in each nation.
- The technical standards and maps, including the flood risk framework, which differs in each nation.
- The procedural description, including the application type, the consultation requirements and the certificates.
Anything the draft flags as "to be confirmed" still needs confirming, and a devolved application adds items to that list rather than removing them. A reviewer with current practice in the relevant nation is the person to do this work, and the professional directory is the route to a reviewer who can sign off a draft.
Labelling a document by jurisdiction
State the jurisdiction on the front of the document and in the policy section. A planning statement that says, in its first paragraph, that it is prepared in respect of an application to a named Welsh planning authority and assessed against Future Wales, Planning Policy Wales edition 12 and the named Local Development Plan tells the officer immediately that the author knows which system they are in.
Keep separate templates rather than one template with a nation field. A shared template invites the error it was meant to prevent, because the structure carries English assumptions in its headings.
And verify the edition of every document you cite at the point of writing. Planning Policy Wales has been revised several times, NPF4 is subject to review, and the Northern Ireland transitional arrangements change as each council adopts its plan. A citation that was correct eighteen months ago may not be correct now.
PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval. For specialist technical reports, qualified professional input may be required, and a devolved application needs the relevant national policy checked by a reviewer practising in that nation.
Frequently asked questions
Does NPF4 form part of the development plan in Scotland?
Yes. National Planning Framework 4, adopted in February 2023, sits within the development plan alongside the Local Development Plan. That differs from England, where the Framework is a material consideration rather than part of the plan. The difference changes how a policy conflict is resolved and therefore how the balancing section of a planning statement has to be written.
What replaces the NPPF in Wales?
Planning Policy Wales, currently in its twelfth edition, sets national planning policy, supported by Technical Advice Notes rather than a guidance portal. The development plan comprises Future Wales: The National Plan 2040, any Strategic Development Plan and the Local Development Plan for the area. Placemaking is the organising idea running through the policy chapters.
Is flood risk assessed the same way across the United Kingdom?
No. Wales applies TAN 15 with its own acceptability framework and its own maps, which is not the Environment Agency Flood Zone system used in England. Scotland and Northern Ireland each have their own arrangements. A flood case argued in English Flood Zone 2 and 3 terms with the English sequential and exception tests will not engage the Welsh framework.
Do the retained Planning Policy Statements still apply in Northern Ireland?
In each council area the retained Planning Policy Statements continue to apply until that council adopts its Local Development Plan, and adoption progress varies between the eleven councils. A document citing only the Strategic Planning Policy Statement will usually have missed the detailed policy that decides the case, which makes this the most common devolved drafting error.
Can an England-grounded AI draft be used for a Welsh application?
Only as a starting structure, and only with the policy base replaced by a reviewer practising in Wales. The national citations, the plan hierarchy, the statutory duties, the technical standards and maps and the procedural description all have to change. Reports should be reviewed before submission, and PlanScope does not guarantee planning approval.
