Protected open space and the policy exceptions

Open space designated in a development plan is protected by a policy that offers three ways through it and no others. National policy says existing open space, sports and recreational buildings and land, including playing fields, should not be built on unless an up-to-date assessment shows the space to be surplus to requirements, or the loss would be replaced by equivalent or better provision in a suitable location, or the development is for alternative sports and recreational provision whose benefits clearly outweigh the loss.

That is the whole structure of protected open space local plan policy, and most refusals happen because the application argued something else: that the space is scruffy, that nobody uses it, that there is other open space nearby, or that the housing need outweighs it. None of those is one of the three exceptions.

How open space gets designated

Three routes put a parcel into the protected category.

A local plan allocation or policies map designation is the common one, drawn from the authority's open space assessment and usually typed by function: parks and gardens, natural and semi-natural space, amenity green space, provision for children and young people, outdoor sports facilities, allotments, cemeteries and churchyards. A neighbourhood plan can designate as well. And Local Green Space is a separate designation made through a local or neighbourhood plan, available only where land is reasonably close to the community it serves, demonstrably special with local significance, and local in character rather than an extensive tract.

The definition of open space in national policy is broad, covering land and areas of water such as rivers, canals, lakes and reservoirs of public value. Public ownership is not part of the test, which is why private land gets caught.

Check which route applies to your parcel, because Local Green Space carries policy consequences aligned with Green Belt protection and the three exceptions do not open the same way.

The exceptions and what each one has to prove

The surplus route needs an assessment of need, not an assertion. That means the authority's own open space study, applied to the relevant typology and catchment, showing supply above the adopted quantity standard with the accessibility standard still met after the loss. Where the study is more than a few years old, commissioning an update is a legitimate step, and an updated assessment prepared to the same methodology carries weight.

The replacement route needs equivalent or better provision for quantity and quality, in a suitable location. Each of those words does work. Equivalent quantity is measured in the same typology, so replacing a kickabout area with a flower bed fails. Better quality has to be evidenced through a site quality assessment rather than claimed. A suitable location means within the catchment the lost space served, judged by walking distance rather than by straight-line distance.

The alternative provision route is the narrowest. The development itself must be sports or recreational provision, and the benefits must clearly outweigh the loss, so a clubhouse replacing part of a pitch can qualify while housing cross-subsidising a new pavilion generally cannot.

Proving surplus against an assessment of need

A surplus case is built on four numbers for the relevant typology: the adopted quantity standard expressed per thousand population, the current provision in the catchment, the projected population including committed development, and the accessibility standard.

Run the arithmetic both with and without the site. Then test it against the quality dimension, because a space can be numerically surplus while being the only accessible provision for part of the catchment. An Open Space Assessment that sets out the standards, the catchment, the site audit and the post-development position is the document that answers the policy, and the catchment definition is where officers push back hardest.

Population projections matter more than people expect. A surplus calculated against today's population can disappear once allocated sites in the plan are built, and an officer will apply the plan period rather than the present day.

Replacement provision, timing and quality

Replacement that arrives after the loss is not replacement. The usual mechanism is a section 106 agreement with a trigger requiring the new provision to be laid out, planted, equipped and available for use before the existing space is taken out of use or before a stated number of occupations.

The agreement also has to deal with the things that make open space work over time: a commuted maintenance sum or an estate charge, a management specification, public access rights secured by dedication or lease, and a restriction preventing later disposal. Where the new space includes equipped play, the provision should be sized and specified through a Play Space Assessment rather than described as a play area on a plan.

Quality improvements can offset a quantity loss only where the adopted standard allows that trade, and many do not. Read the policy wording rather than assuming the trade is available.

Private land caught by a designation

Hospital grounds, school fields, works sports grounds, allotment sites, large gardens and the grounds of institutional buildings all end up inside open space designations, often with no public access at all.

The designation still applies. What changes is the evidence: a space with no public access contributes to visual amenity and to the character of an area, and may contribute to biodiversity, but it does not contribute to the usable supply the quantity standard measures. That is a real argument on the surplus limb, and it is stronger when supported by the authority's own study, which will usually have excluded inaccessible land from its calculations.

Three statutory consents sit alongside planning and catch people out. Disposal of land held as public open space by a local authority requires advertisement under the Local Government Act 1972. Disposal or change of use of a school playing field needs consent from the Secretary of State under the School Standards and Framework Act 1998. And statutory allotments cannot be disposed of without ministerial consent. Common land brings its own regime, as our note on common land and consent for works sets out.

Playing fields and the extra consultee

Sport England is a statutory consultee on development affecting playing fields, and it operates its own policy with a defined set of exceptions covering matters such as development on land incapable of forming part of a playing pitch, replacement by equivalent or better provision, and development of ancillary facilities supporting the use.

Two practical points follow. A playing field objection from Sport England is hard to overcome without satisfying one of those exceptions, whatever the planning balance says. And land last used as a playing field within the recent past can still attract the consultation, so a field left fallow for two seasons is not outside the regime.

Where pitch provision is involved, the authority's playing pitch strategy is the document to work from, since it assesses supply and demand sport by sport rather than by area.

Writing the submission so it answers the policy

Name the exception you are relying on in the first paragraph of the open space section, then prove it element by element. If you are running the surplus limb, give the standard, the catchment, the supply, the population and the post-development position in a table. If you are running the replacement limb, give the quantity and quality comparison, the location and walking distances, the delivery trigger and the maintenance mechanism.

Do not run all three in the alternative and hope one lands. An application that argues surplus and replacement and alternative provision at once reads as an application with no case, and a case officer will say so in the report. Pick the limb the evidence supports, and if none of them does, the honest conclusion is that the scheme needs redesigning around the space rather than through it.

The list of documents a scheme like this usually needs is worth checking early against the full set of report types, because open space cases often pull in ecology, play provision and landscape evidence together.
