13. Protecting Green Belt land

Paragraphs 142 to 160

142. The government attaches great importance to Green Belts. The fundamental aim of Green Belt policy is to prevent urban sprawl by keeping land permanently open; the essential characteristics of Green Belts are their openness and their permanence.

143. Green Belt serves 5 purposes:

(a) to check the unrestricted sprawl of large built-up areas;

(b) to prevent neighbouring towns merging into one another;

(c) to assist in safeguarding the countryside from encroachment;

(d) to preserve the setting and special character of historic towns; and

(e) to assist in urban regeneration, by encouraging the recycling of derelict and other urban land.

144. The general extent of Green Belts across the country is already established. New Green Belts should only be established in exceptional circumstances, for example when planning for larger scale development such as new settlements or major urban extensions. Any proposals for new Green Belts should be set out in strategic policies, which should:

(a) demonstrate why normal planning and development management policies would not be adequate;

(b) set out whether any major changes in circumstances have made the adoption of this exceptional measure necessary;

(c) show what the consequences of the proposal would be for sustainable development;

(d) demonstrate the necessity for the Green Belt and its consistency with strategic policies for adjoining areas; and

(e) show how the Green Belt would meet the other objectives of the Framework.

145. Once established, Green Belt boundaries should only be altered where exceptional circumstances are fully evidenced and justified through the preparation or updating of plans. Strategic policies should establish the need for any changes to Green Belt boundaries, having regard to their intended permanence in the long term, so they can endure beyond the plan period. Where a need for changes to Green Belt boundaries has been established through strategic policies, detailed amendments to those boundaries may be made through non-strategic policies, including neighbourhood plans.

146. Exceptional circumstances in this context include, but are not limited to, instances where an authority cannot meet its identified need for homes, commercial or other development through other means. If that is the case, authorities should review Green Belt boundaries in accordance with the policies in this Framework and propose alterations to meet these needs in full, unless the review provides clear evidence that doing so would fundamentally undermine the purposes (taken together) of the remaining Green Belt, when considered across the area of the plan.

147. Before concluding that exceptional circumstances exist to justify changes to Green Belt boundaries, the strategic policy-making authority should be able to demonstrate that it has examined fully all other reasonable options for meeting its identified need for development. This will be assessed through the examination of its strategic policies, which will take into account the preceding paragraph, and whether the strategy:

(a) makes as much use as possible of suitable brownfield sites and underutilised land;

(b) optimises the density of development in line with the policies in chapter 11 of this Framework, including whether policies promote a significant uplift in minimum density standards in town and city centres and other locations well served by public transport; and

(c) has been informed by discussions with neighbouring authorities about whether they could accommodate some of the identified need for development, as demonstrated through the statement of common ground.

148. Where it is necessary to release Green Belt Land for development, plans should give priority to previously developed land, then consider grey belt which is not previously developed, and then other Green Belt locations. However, when drawing up or reviewing Green Belt boundaries, the need to promote sustainable patterns of development should determine whether a site’s location is appropriate with particular reference to paragraphs 110 and 115 of this Framework. Strategic policy-making authorities should consider the consequences for sustainable development of channelling development towards urban areas inside the Green Belt boundary, towards towns and villages inset within the Green Belt or towards locations beyond the outer Green Belt boundary.

149. When defining Green Belt boundaries, plans should:

(a) ensure consistency with the development plan’s strategy for meeting identified requirements for sustainable development;

(b) not include land which it is unnecessary to keep permanently open;

(c) where necessary, identify areas of safeguarded land between the urban area and the Green Belt, in order to meet longer-term development needs stretching well beyond the plan period;

(d) make clear that the safeguarded land is not allocated for development at the present time. Planning permission for the permanent development of safeguarded land should only be granted following an update to a plan which proposes the development;

(e) be able to demonstrate that Green Belt boundaries will not need to be altered at the end of the plan period; and

(f) define boundaries clearly, using physical features that are readily recognisable and likely to be permanent.

150. If it is necessary to restrict development in a village primarily because of the important contribution which the open character of the village makes to the openness of the Green Belt, the village should be included in the Green Belt. If, however, the character of the village needs to be protected for other reasons, other means should be used, such as conservation area or normal development management policies, and the village should be excluded from the Green Belt.

151. Once Green Belts have been defined, local planning authorities should plan positively to enhance their beneficial use, such as looking for opportunities to provide access; to provide opportunities for outdoor sport and recreation; to retain and enhance landscapes, visual amenity and biodiversity; or to improve damaged and derelict land. Where Green Belt land is released for development through plan preparation or review, the ‘Golden Rules’ in paragraph 156 below should apply.

152. The National Forest and Community Forests offer valuable opportunities for improving the environment around towns and cities, by upgrading the landscape and providing for recreation and wildlife. The National Forest Strategy and an approved Community Forest Plan may be a material consideration in preparing development plans and in deciding planning applications. Any development proposals within the National Forest and Community Forests in the Green Belt should be subject to the normal policies for controlling development in Green Belts.

Proposals affecting the Green Belt

153. When considering any planning application, local planning authorities should ensure that substantial weight is given to any harm to the Green Belt, including harm to its openness 55 . Inappropriate development is, by definition, harmful to the Green Belt and should not be approved except in very special circumstances. ‘Very special circumstances’ will not exist unless the potential harm to the Green Belt by reason of inappropriateness, and any other harm resulting from the proposal, is clearly outweighed by other considerations.

154. Development in the Green Belt is inappropriate unless one of the following exceptions applies:

a) buildings for agriculture and forestry;

b) the provision of appropriate facilities (in connection with the existing use of land or a change of use), including buildings, for outdoor sport, outdoor recreation, cemeteries and burial grounds and allotments; as long as the facilities preserve the openness of the Green Belt and do not conflict with the purposes of including land within it;

c) the extension or alteration of a building provided that it does not result in disproportionate additions over and above the size of the original building;

d) the replacement of a building, provided the new building is in the same use and not materially larger than the one it replaces;

e) limited infilling in villages;

f) limited affordable housing for local community needs under policies set out in the development plan (including policies for rural exception sites); and

g) limited infilling or the partial or complete redevelopment of previously developed land (including a material change of use to residential or mixed use including residential), whether redundant or in continuing use (excluding temporary buildings), which would not cause substantial harm to the openness of the Green Belt.

h) Other forms of development provided they preserve its openness and do not conflict with the purposes of including land within it. These are:

i. mineral extraction;

ii. engineering operations;

iii. local transport infrastructure which can demonstrate a requirement for a Green Belt location;

iv. the re-use of buildings provided that the buildings are of permanent and substantial construction;

v. material changes in the use of land (such as changes of use for outdoor sport or recreation, or for cemeteries and burial grounds); and

vi. development, including buildings, brought forward under a Community Right to Build Order or Neighbourhood Development Order.

155. The development of homes, commercial and other development in the Green Belt should also not be regarded as inappropriate where:

a. The development would utilise grey belt land and would not fundamentally undermine the purposes (taken together) of the remaining Green Belt across the area of the plan;

b. There is a demonstrable unmet need for the type of development proposed 56 ;

c. The development would be in a sustainable location, with particular reference to [paragraphs 110 and 115 of this Framework] 57 ; and

d. Where applicable the development proposed meets the ‘Golden Rules’ requirements set out in paragraphs 156-157 below.

156. Where major development involving the provision of housing is proposed on land released from the Green Belt through plan preparation or review 58 , or on sites in the Green Belt subject to a planning application 59 , the following contributions (‘Golden Rules’) should be made:

a. affordable housing which reflects either: (i) development plan policies produced in accordance with paragraphs 67-68 of this Framework; or (ii) until such policies are in place, the policy set out in paragraph 157 below;

b. necessary improvements to local or national infrastructure; and

c. the provision of new, or improvements to existing, green spaces that are accessible to the public. New residents should be able to access good quality green spaces within a short walk of their home, whether through onsite provision or through access to offsite spaces.

157. Before development plan policies for affordable housing are updated in line with paragraphs 67-68 of this Framework, the affordable housing contribution required to satisfy the Golden Rules is 15 percentage points above the highest existing affordable housing requirement which would otherwise apply to the development, subject to a cap of 50% 60 . In the absence of a pre-existing requirement for affordable housing, a 50% affordable housing contribution should apply by default. The use of site-specific viability assessment for land within or released from the Green Belt should be subject to the approach set out in national planning practice guidance on viability.

158. A development which complies with the Golden Rules should be given significant weight in favour of the grant of permission.

159.The improvements to green spaces required as part of the Golden Rules should contribute positively to the landscape setting of the development, support nature recovery and meet local standards for green space provision where these exist in the development plan. Where no locally specific standards exist, development proposals should meet national standards relevant to the development (these include Natural England standards on accessible green space and urban greening factor and Green Flag criteria). Where land has been identified as having particular potential for habitat creation or nature recovery within Local Nature Recovery Strategies, proposals should contribute towards these outcomes.

160. When located in the Green Belt, elements of many renewable energy projects will comprise inappropriate development. In such cases developers will need to demonstrate very special circumstances if projects are to proceed. Such very special circumstances may include the wider environmental benefits associated with increased production of energy from renewable sources.


(55) Other than in the case of development on previously developed land or grey belt land, where development is not inappropriate.

(56) Which, in the case of applications involving the provision of housing, means the lack of a five year supply of deliverable housing sites, including the relevant buffer where applicable, or where the Housing Delivery Tests was below 75% of the housing requirement over the previous 3 years; and in the case of traveller sites means the lack of a 5 year supply of deliverable traveller sites assessed in line with Planning Policy for Traveller sites.

(57) In the case of development involving the provision of traveller sites, particular reference should be made to Planning Policy for Traveller Sites paragraph 13.

(58) The Golden Rules do not apply to: (i) developments brought forward on land released from the Green Belt through plans that were adopted prior to the publication of this Framework; and (ii) developments that were granted planning permission on Green Belt land prior to the publication of this Framework.

(59) Including where there are variations made to existing permissions (where the existing permission involved development that was subject to the Golden Rules).

(60) The 50% cap does not apply to rural exception sites or community-led development exception sites, or if the local planning authority has a relevant existing policy which would apply to the development which is above 50%.
