Local Green Space or Green Belt: which protects a field

Local Green Space and Green Belt both stop most development on open land, but they are made in different ways and for different reasons. Local Green Space is a designation a community can push for through a local plan or a neighbourhood plan, applied to a specific field, orchard, recreation ground or churchyard that matters to the people next to it. Green Belt is a strategic designation drawn around large built-up areas to keep land permanently open, and only a plan review by the local planning authority can move its boundary. If you are trying to protect one field from housing, Local Green Space is usually the realistic route.

The confusion is understandable. Once either designation is in place, the policy wording in the National Planning Policy Framework (edition published 17 August 2026) treats development on Local Green Space in a way consistent with Green Belt policy. Same restriction, very different origin.

What each designation is protecting

Green Belt exists to keep land permanently open. The Framework sets out five purposes: checking unrestricted sprawl of large built-up areas, preventing neighbouring towns merging into one another, assisting in safeguarding the countryside from encroachment, preserving the setting and special character of historic towns, and assisting urban regeneration by encouraging the recycling of derelict land. Notice what is missing from that list. Nothing about beauty, wildlife or how much local people value the land. A scrubby lay-by can serve a Green Belt purpose perfectly well because openness, not quality, is the point.

Local Green Space works the other way round. It protects land because a particular community holds it to be special: for its beauty, its historic significance, its recreational value, its tranquillity or its richness of wildlife. The value is local and evidenced, and the designation attaches to a defined parcel rather than a belt of countryside.

Who designates, and through which process

Green Belt boundaries are set in the development plan. A local planning authority can only alter them through plan-making, and the Framework requires exceptional circumstances, fully evidenced and justified, tested by an inspector. That is a multi-year process with a call for sites, a Green Belt review, consultation and an examination in public. A community can take part, but cannot start it.

Local Green Space has two routes, and both end in an examined plan:

1. The local plan. The authority designates through a plan review or a plan update, so the designation is examined alongside the rest of the plan.
2. A neighbourhood plan. A parish or town council, or a designated neighbourhood forum, allocates the land in the plan, which is examined and then put to a local referendum.

The neighbourhood plan route is the one most campaigns use, because the community writes the plan. It is slower than people expect. Designating the area, drafting policy, gathering evidence, consultation, examination and referendum rarely takes under two years, and the plan then has to be made by the authority before the policy carries full weight. Land already allocated for development in an adopted plan is very hard to designate.

The test applied once the designation exists

For Green Belt, development that is not within the Framework's list of exceptions is inappropriate, and inappropriate development should be refused unless very special circumstances exist. Those circumstances only exist where the harm to the Green Belt, and any other harm, is clearly outweighed by other considerations. Householder extensions are dealt with through the exception for extensions that are not disproportionate to the original building, which is why Green Belt extension refusals so often turn on volume calculations rather than design.

Local Green Space attracts policy consistent with that approach. In practice an authority will refuse most new building on designated land and will look for the same weight of justification.

Proximity, scale and the limit on extensive tracts

Three criteria decide most Local Green Space arguments. The land has to be in reasonably close proximity to the community it serves, so a beauty spot five miles away will fail. It has to be demonstrably special to that community and hold a particular local significance. And it has to be local in character and not an extensive tract of land.

That last criterion is where campaigns come unstuck. Inspectors have consistently read it as ruling out designations used to draw a green cordon around a settlement, however sincerely the countryside is valued. There is no acreage threshold in national policy, which is deliberate, so the judgement is about whether the parcel reads as a discrete local space or as open countryside. A 3 ha recreation ground with defined boundaries is arguable. Forty hectares of arable land on the settlement edge is not.

The designation also has to be capable of lasting beyond the end of the plan period. Land needed for development to meet identified housing or employment requirements will not be designated, because the plan has to add up.

Evidence a community can realistically gather

Designation is an evidence exercise, not a petition. What works is specific and verifiable: dates and photographs of the uses the land supports, minutes of the parish council recording its role, a record of a war memorial or a historic field boundary, a species list from a local wildlife group, records of public access, and the outcome of a survey with a stated response rate rather than a claim about strength of feeling. Where wildlife value is part of the case, a short ecological note from a suitably qualified surveyor carries more weight than anecdote. The same discipline that sits behind a planning submission applies here, and a Landscape and Visual Impact Assessment or an Open Space Assessment prepared for a nearby application can be a useful source of baseline description you do not have to pay for again.

Keep the parcel boundary tight and draw it on an ordnance-based plan. Vague boundaries get deleted at examination.

Review, removal and defending the designation

Neither designation is permanent in practice. Both are revisited when the plan is reviewed, and authorities are expected to keep plans up to date. A Local Green Space can be deleted through a plan review if the evidence no longer stands or the land is needed to meet a requirement. A Green Belt boundary can be redrawn where the authority meets that plan-making test, and recent national policy has pushed authorities to review boundaries where housing need cannot otherwise be met, including the treatment of previously developed and poorer quality Green Belt land introduced by the December 2024 Framework and carried forward since. Check the current edition on gov.uk before relying on any wording, because this part of policy has changed twice in two years.

A designation does not stop an application being made. It changes the test the application has to pass, which means the community still has to respond to consultations, and the arguments that succeed are the ones tied to adopted policy. Objections that rely on the designation alone, without addressing the applicant's case on harm and benefit, are easy for a case officer to summarise and set aside. If a protected tree is part of what you are defending, the consent process for works to that tree runs separately, as set out in our note on tree surveys and TPO applications.

Which route suits a campaign

If the land is a discrete, locally valued space and your parish council is willing, the neighbourhood plan route gives a community genuine control, and the referendum gives the policy democratic weight that is hard to argue with at appeal. If the concern is the general spread of a town into countryside, Green Belt is the relevant tool, and the only lever is the plan review: respond to the call for sites, engage with the Green Belt review methodology, and make representations at examination.

Either way, get the evidence together before the plan timetable reaches consultation. Authorities publish a local development scheme with the dates in it.
