An open field, a green-looking site and land designated as Green Belt are not the same thing. Before preparing a comment, check the council's adopted policies map and the relevant policy documents. Record the designation that actually covers the site. Do not infer it from an estate agent's description, a satellite image or the colour of the land.
This guide uses the national Framework published in August 2026, with its accessible chapters published in September 2026. Older decisions and guidance may use different policy numbers and tests. Check the current version before transferring a quotation.
Establish the designation and the question being decided
Find the site boundary on the application plan and compare it with the adopted policy map. Identify any other designation separately, such as a protected landscape, conservation area or local open-space designation. Overlapping boundaries do not make the policies interchangeable.
A planning application is also different from a proposal to change Green Belt boundaries through plan preparation. The current Framework deals separately with those tasks. A comment on one application should address the relevant development proposal; it is not a substitute for responding to a Local Plan consultation.
Ask which policy route the application statement relies upon. Does it say the development falls within a category that is not inappropriate, or does it seek to justify inappropriate development? Quote the actual argument accurately before explaining any disagreement.
Read the conditions attached to a policy category
Current national Green Belt policy is in GB6–GB8. The categories in GB7 have their own wording and qualifications. A label such as “replacement building”, “previously developed land” or “grey belt” does not, on its own, establish that every requirement is met.
For an extension or replacement, identify the original, existing and proposed buildings and the evidence supporting that comparison. For a claimed land classification, identify the relevant assessment and the area it actually considers. Do not create your own percentage limit or assume that an unattractive site must qualify for development.
The current policy also contains provisions involving grey belt, station-related development and contributions for certain housing proposals. These require the actual policy, definitions, evidence and applicable qualifications. This guide does not classify a site, calculate a contribution or certify that a proposal meets them.
Where development is inappropriate, GB6 sets the very-special-circumstances test. It should not be reduced to a slogan that all Green Belt building is forbidden. Equally, identifying a possible benefit does not establish that the policy balance has been satisfied.
Describe openness with evidence
Openness is not simply how attractive a view looks. Planning guidance explains that the judgement can involve spatial and visual aspects, duration and remediability, and the activity generated. Which aspects matter depends on the actual proposal and applicable policy route.
Compare the footprint, height, volume, position and activity shown in existing and proposed documents. State where you obtained dimensions. If proposed buildings are screened by planting, distinguish the physical presence of development from whether it is visible from one viewpoint.
Describe a relevant public view where it helps explain the relationship, but do not assume an absence of visibility proves no effect on openness. Nor should the loss of your private view be presented as a complete Green Belt argument.
The landscape and views guide explains the separate task of identifying landscape character and visual effects. The private-views guide helps distinguish a private preference from a planning concern.
Metropolitan Open Land needs its own source trail
In London, check whether the site is designated Metropolitan Open Land rather than assuming that every park or open space has that status. The GLA's current-plan page identifies the adopted London Plan 2021 as still operative, while a successor is being developed.
Policy G3, on printed pages 317–318 of that adopted plan, addresses MOL protection, designation and boundary alteration. It refers to national Green Belt tests, but that is not a reason to assume that every new national category automatically resolves a particular MOL proposal. Read the adopted policy, current national wording and the application's reasoning together.
If a statement makes a claim about grey belt or another national category on MOL, ask for the policy basis and evidence. This guide does not provide a site-specific interpretation of that interaction. A draft replacement plan must be identified by its actual stage rather than described as already adopted.
Keep other countryside effects distinct
Land outside Green Belt can still raise landscape, ecological, access, flood-risk or heritage questions under applicable policies. Conversely, a Green Belt designation does not prove each of those harms.
Organise your comment by the actual policy question, the proposed change and the supporting document. Identify a missing comparison or unexplained assumption rather than asserting that any development outside a settlement is unlawful. Ask the council to assess the specific issue under the current policy framework.
Historic appeal decisions can illustrate how evidence was considered at the time. They cannot replace checking today's wording or establish that the same result must follow on another site.
