Safeguarded land between Green Belt and settlement

Safeguarded land is the strip a local plan holds back when it alters a Green Belt boundary: land taken out of the Green Belt, not allocated for anything, and reserved to meet development needs well beyond the current plan period. Safeguarded land planning policy therefore puts a site in an unusual position. Green Belt policy no longer applies to it, so there is no inappropriate development test and no need for very special circumstances. But national policy says permission for permanent development should only be granted following a local plan review that proposes the development.

That is a narrow gap to work in, and it explains why promoters of safeguarded land spend most of their effort on the plan process rather than on applications. It also explains why the occasional application does succeed, because the policy is a strong material consideration rather than a statutory prohibition.

Why plans create it

When an authority concludes it must release Green Belt land to meet its needs, national policy asks it to do several things at once: demonstrate that the circumstances justifying the alteration are exceptional, release land in a way that promotes sustainable patterns of development, and where necessary identify safeguarded land to meet longer-term needs stretching well beyond the plan period, so that the new Green Belt boundary will not need moving again at the end of the plan.

Safeguarding is the mechanism that makes a boundary alteration durable. Without it, an authority releasing exactly enough land for 15 years would be back altering the boundary at the next review, which is what the permanence requirement is intended to prevent.

The policy also requires plans to make clear that safeguarded land is not allocated for development at the present time. That phrase is the hinge the whole argument turns on.

How it differs from Green Belt and from allocated land

The middle column is the whole point. Removing Green Belt status removes the hardest policy test in the English planning system, and an applicant who has read only the first column will overestimate their position. An applicant who has read only the national policy sentence about awaiting a plan review will underestimate it.

Applications made before release

The policy position is that permanent development should await a plan review. Weight is the question, and three factors move it.

The first is the state of the development plan. Where the plan is up to date, the housing requirement is being met and the five-year supply is demonstrated, an early application on safeguarded land has very poor prospects. The policy and the plan point the same way and there is no engine driving a departure.

The second is whether the presumption in favour of sustainable development is engaged. Where the authority cannot demonstrate the required supply, or fails the Housing Delivery Test, the balance tilts and policies most important for determining the application are rendered out of date. Safeguarded land is not protected by the categories of national policy that disapply the tilted balance, so the balance can apply. Inspectors have nonetheless given substantial weight to the safeguarding policy itself in a number of appeals, treating premature release as harm to the plan-led system. Those decisions are indicative of how inspectors approach the issue rather than binding precedent.

The third is the stage of an emerging plan. Where a review is well advanced and proposes to release your site, weight attaches to the emerging policy according to its stage of preparation, the extent of unresolved objections and its consistency with national policy. A site proposed for release in a plan at examination is in a materially different position from one in a draft at consultation.

One caveat worth stating plainly: the national policy framework for Green Belt has been amended more than once in recent years, including the introduction of a distinct category of lower-performing Green Belt land. Check the current edition for how safeguarding and release are now expressed before relying on the formulation above.

Release through a plan review

Promoting a site for release is a plan-making exercise and the evidence is plan-making evidence.

What an authority needs before it can allocate is a demonstration that the site is deliverable or developable, which means available, suitable and achievable. In practice that means ownership or an option with a long enough term, an access that the highway authority has commented on, utilities capacity confirmed by the relevant undertakers, a flood and drainage position, an ecological baseline, a heritage and archaeological appraisal, and a landscape appraisal where the site forms the settlement edge. A Landscape and Visual Impact Assessment prepared to the recognised methodology is usually what settles the edge question, and councils expect a suitably qualified author with professional review strongly advised.

Engage at every consultation stage and respond to the land availability assessment rather than waiting for the draft plan. Sites get discounted at the assessment stage for reasons as simple as an unconfirmed access, and recovering from that is harder than preventing it.

Interim uses, and the trap in them

Safeguarded land sits idle for years, so temporary and interim uses are attractive. Open storage, car parking, sports pitches, nurseries, meanwhile uses and agricultural continuation are all commonly consented, usually with a condition limiting the period and requiring restoration.

Two cautions. A use that becomes established can be argued to prejudice the eventual scheme, particularly where it generates a community interest in retaining it, so a sports pitch is a more complicated interim use than a storage yard.

The second is ecological, and it is underappreciated. Land left ungrazed and unmanaged for a decade can develop habitat of real value, which raises the baseline for a biodiversity net gain calculation and makes the eventual development more expensive to deliver. A Biodiversity Net Gain Assessment run against a high baseline needs more compensation, and the Environment Act 2021 regime expects a competent person to complete the statutory metric. Protected species can colonise too. Habitat mapping is also often wrong at this scale, as our note on priority habitat inventory and how far to trust it sets out, so establish your own baseline early.

Managing land under an agricultural or grassland regime through the safeguarding period, with records kept, is a legitimate approach and considerably less fraught than discovering a priority habitat on your own site at application stage.

Realistic prospects

For permanent housing before a plan review, prospects are poor unless the plan is substantially out of date, the authority is failing on delivery, and the site is uncontroversial on every other ground. Treat an early application as a way of testing the authority's position and building a case for the review, and budget for an appeal.

Better uses of the same money are usually: a thorough technical evidence base assembled now, active engagement in the plan review, an agreed access solution, and a site promotion document the authority's officers can lift into their assessment. The document set is worth scoping early against the full list of report types, because the evidence needed for allocation is close to the evidence needed for the application that follows.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it. Enter your postcode on PlanScope to see which reports your site is likely to need.
