National planning standards: a source guide for England
Start with the refusal reason and the policy it cites. These summaries help you find the relevant national source, understand its role and identify what to check in the local plan and the evidence for your proposal.

Read national policy alongside the development plan
The current Framework was published on 17 August 2026. It separates plan-making and national decision-making policies, so an older paragraph number may no longer identify the right provision.
Applications are determined in accordance with the development plan unless material considerations indicate otherwise. The Framework’s national decision-making policies are material considerations, read alongside development-plan policies.

Annex A says local policies materially inconsistent with the Framework’s national decision-making policies should receive very limited weight, except where examined and adopted or made against this Framework. Other local policies should not lose weight simply because they predate it.

Design, character and neighbours’ living conditions
For a refusal about design or neighbours, identify the physical relationship that caused concern: scale, layout, windows, light, privacy or the character of the surroundings. Then locate the relevant national and local design guidance.
The National design guide describes characteristics of well-designed places. It is intended to be read with the guidance on design processes and tools, rather than used as a site-specific design approval.

The National Model Design Code provides a process and design parameters for local codes. Check whether the council has an adopted code or guide that applies to the site and proposal.

The January 2026 Design and Placemaking publication remains labelled a consultation draft on its official page. Its publication does not establish that it has replaced the existing guidance.

Internal space, accessibility and water efficiency
A national standard may depend on a particular planning policy or permission route. Establish that connection before measuring a proposal against a technical figure.
Where the nationally described space standard applies, Table 1 gives a one-bedroom, one-person, single-storey dwelling a minimum internal area of 39 m², or 37 m² with a shower room instead of a bathroom. Bedroom, storage and other provisions also apply; this is not a general minimum for every existing home or extension.

The space standard belongs to planning, rather than building regulations. The optional standards guidance allows councils to set national access, water and space requirements through local policies supported by evidence. Establish the relevant policy or permission route before applying a technical figure.

Approved Document M distinguishes visitable, accessible and adaptable, and wheelchair-user dwellings. Its publication page states that categories 2 and 3 apply where required by planning permission.

Check whether the work needs a planning application
A refused proposal and a possible permitted-development alternative may have different dimensions, limitations and procedural requirements. Check the exact work and site rather than assuming one route settles the other.
The householder technical guidance explains the different classes for extensions, roofs, porches, outbuildings and other works. A proposal must satisfy all relevant limitations and conditions to benefit from permitted-development rights.
Permitted development rights for householders: technical guidance (official source, opens in a new tab) · Introduction: The structure of the rules on permitted development
The permission guidance explains the role of Article 4 directions and other restrictions. The lawful-development guidance describes the separate certificate process and its evidential requirements.

Green Belt and the location of development
First establish the site designation and the proposal’s category. Labels such as Green Belt, grey belt and countryside have different roles and do not establish permission by themselves.
The Framework’s GB6 and GB7 policies distinguish inappropriate development from the specified categories that are not inappropriate. Read the qualifications for the relevant category and the remaining applicable policies.

The Green Belt practice guidance discusses evidence about openness and grey belt. Its February 2025 revision predates the current Framework, so check any policy cross-references against the 2026 text.

Heritage significance and the effect of the proposal
For a heritage refusal, identify the asset, what contributes to its significance and how the proposal would affect it. The relevant evidence may concern the building, its setting or archaeological interest.
Heritage significance can arise from archaeological, architectural, artistic or historic interest and from the asset’s setting. Assess how the proposed physical change or change to setting affects that significance; describing the age or appearance of the building alone does not answer the question.
Historic environment (official source, opens in a new tab) · What is ‘significance’?; Why is ‘significance’ important in decision-making? (paragraphs 006–007)
Setting can extend beyond an asset’s curtilage and is not confined to views: historic relationships, noise and other environmental effects can contribute. Listed buildings and conservation areas also engage statutory duties alongside national and local planning policy.

Flood evidence and sustainable drainage
A drainage proposal needs to address the site and the receiving system. Distinguish the planning flood-risk assessment from the detailed design, maintenance and operation of drainage.
Flood-risk practice guidance explains evidence, the sequential and exception tests, and site-specific assessments. Read the relevant procedure with the current national policy and the council’s local flood evidence.

The 2025 SuDS standards are non-statutory. They address runoff destinations, everyday and extreme rainfall, water quality, amenity, biodiversity and drainage throughout construction and operation.

Nature, protected habitats and trees
The evidence needed depends on the site, the affected species or habitat and the works proposed. Biodiversity net gain, protected habitats and tree controls are separate checks.
Development that is the subject of a householder application is exempt from statutory biodiversity net gain. The exemption uses the defined application category; it does not cover every proposal to build housing or settle separate habitat, species and tree questions.
Biodiversity net gain (official source, opens in a new tab) · Which planning permissions are in scope and which are exempt from biodiversity net gain?
Measures specifically added to avoid or reduce harm to a protected habitats site cannot be counted at the screening stage to avoid an appropriate assessment. They are assessed within the appropriate assessment itself; features integral to the project need to be distinguished from mitigation added for that purpose.

The tree guidance distinguishes Tree Preservation Orders from the procedures for trees in conservation areas. Check the tree’s status and the proposed works before relying on a general planning conclusion.

Access, parking and transport evidence
For an access or parking refusal, identify whether the disputed point concerns highway safety, movement, parking provision or the evidence submitted. The scale and location of the proposal matter to the assessment.
Transport guidance explains the purpose and content of travel plans, transport assessments and statements. Match the document requested by the council to the impacts that need to be assessed.
Travel Plans, Transport Assessments and Statements (official source, opens in a new tab) · Overarching principles; Transport Assessments and Statements
The transport evidence guidance covers the relationship between a proposal and the wider network. Use it alongside the applicable local evidence and highway authority response.

Conditions, obligations and changes to a permission
Identify whether the disputed matter concerns the principle of development, a condition or an agreement. The available procedures and evidence differ.
Practice guidance describes six tests: a condition should be necessary, relevant to planning, relevant to the permitted development, enforceable, precise and reasonable in all other respects. Each proposed condition needs to satisfy every test, rather than relying on standard wording alone.

The current Framework groups those requirements in DM6 and says conditions should not require money payments or the formal transfer of land. Restrictions on national permitted-development rights need clear justification; obligations should be used only where a condition cannot address the unacceptable impact.

The obligations guidance explains their role and the tests for taking an obligation into account. Read any proposed commitment against the development and the identified planning impact.

Guidance on flexible permissions distinguishes non-material amendments from applications to vary or remove conditions. A change to a scheme needs the appropriate procedure, rather than an assumption that an existing permission covers it.

Use the sources to identify the next research step
List each refusal reason, its cited policy and the evidence behind it. That helps distinguish a possible design change from missing information or a disagreement about how policy applies.
The appeals guidance explains appeal rights, procedures and costs. Check the route and the applicable deadline in the official guidance for the decision concerned before deciding what to do next.

Pre-application guidance describes discussions that can clarify evidence and design issues. It can help frame a defined request to the council or a professional when considering amendments or resubmission.

Keep building regulations checks separate
The Approved Documents explain ways of meeting building regulations. Planning permission does not settle those requirements, and meeting a technical building standard does not by itself settle a planning refusal.
The official Approved Documents collection covers structural safety, fire, ventilation, energy, accessibility and other building requirements. Select the document for the building type and work concerned, then check its scope and transition provisions.
