Conservation area (United Kingdom)

Last updated

In the United Kingdom, the term conservation area almost always applies to an area (usually urban or the core of a village) of special architectural or historic interest, the character of which is considered worthy of preservation or enhancement. It creates a precautionary approach to the loss or alteration of buildings and/or trees, thus it has some of the legislative and policy characteristics of listed buildings and tree preservation orders. The concept was introduced in 1967, and by 2017 almost 9,800 had been designated in England. [1] [2]



The original idea of historic conservation areas was proposed by June Hargreaves, a York town planner, in her 1964 book Historic buildings. Problems of their preservation. [3] In the book she critiqued the idea that historic buildings should be replaced with modern "streamlined and ultra-functional" buildings as this would be detrimental to the identity of historic towns: "No building within an 'area of special preservation' should be demolished or altered in such a way as to materially detract from the contribution it makes to the group value of the street." [4]


The current legislation in England and Wales, the Planning (Listed Buildings and Conservation Areas) Act 1990 (sections 69 and 70), defines the quality of a conservation area as being: "the character or appearance of which it is desirable to preserve or enhance". The current Scottish legislation is the Planning (Listed Buildings and Conservation Areas) (Scotland) Act 1997. In Northern Ireland it is the Planning Act (Northern Ireland) 2011.

The Civic Amenities Act 1967 introduced the concept of conservation areas, [5] and in September of that year the first designation was made, covering the "old town" area of Stamford, Lincolnshire. [6] [7] The legislation was refined by section 277 of the Town and Country Planning Act 1971, [8] which in turn was superseded by the 1990 Act.

Types of conservation area

Conservation areas can be found across a wide a range of urban and rural UK locations. For example, in the historic centres of town and cities such as Alexandra Palace and Park; [9] model housing estates; historic mining, fishing and transport areas e.g. Crosby Garrett; [10] and rural villages such as Osmotherley. [11]

In conservation areas, it is the protection of the quality and special interest of the neighbourhood or area as a whole that is intended, rather than specific buildings. For example, the layout of boundaries, roads, vistas and viewpoints, trees and green features, street furniture and surfaces, the characteristic building materials of the area, the mix of different uses, and the design of shop fronts may all be taken into account when deciding whether an area has a particular special architectural or historic interest.

It is the role of the listed building process to protect individual buildings, and it is common for many listed buildings to also be located within designated conservation areas where those individual buildings make a contribution to the special architectural or historic character of the area.

Current Government planning policy on conservation areas is laid down (for England) mainly in section 12 'Conserving and enhancing the historic environment' of the National Planning Policy Framework (NPPF) and (for Wales) in Welsh Office Circular 61/96 – Planning and the Historic Environment: Historic Buildings and Conservation Areas.

There are additional planning controls over certain works carried out within the conservation area. For example, demolition within conservation areas requires consent. The designation does not preclude development from taking place, but does require that developments preserve or enhance the historic character of the area, for example by ensuring that newly constructed buildings are of a high quality design. Conservation area status also removes some permitted development rights that apply in undesignated areas.

In England, conservation area consent was abolished by the ERR Act (1) and replaced with a requirement for planning permission for demolition of a building in a conservation area (1). In Wales, the requirement for conservation area consent remains. The circumstances in which such planning permission is required and the consequences of failing to apply for it when it is needed are the same as applied to conservation area consent. [12]

Designation of conservation areas

Local authorities are chiefly responsible for designating conservation areas. They can designate any area of 'special architectural or historic interest' whose character or appearance is worth protecting or enhancing. Local and regional criteria are used, rather than any national standard. In exceptional circumstances, Historic England can designate conservation areas in London, but it has to consult the relevant Borough Council and obtain the consent of the Secretary of State for Culture Media and Sport. The Secretary of State can also designate in exceptional circumstances – usually where the area is of more than local interest. [13]

Local authorities have additional powers under planning legislation to control changes to buildings in a conservation area that might usually be allowed without planning permission in other locations, for example changing the appearance of windows, adding external cladding or putting up satellite dishes.

Identity areas

Large conservation areas are sometimes subdivided into identity areas, which cover groups of buildings and features having similar character and appearance. [14]


Enforcement of conservation areas varies, dependent on the resources and priorities of the local authority, and many fail to meet expectations.[ citation needed ] A conservation area may have a conservation area advisory committee, a non-elected body of people, some of whom may be expert, who are concerned about the conservation in the particular area. [15] Historic England maintains an "at risk" register which includes conservation areas. [16]


The law generally requires that anyone proposing to cut down or carry out any work on any tree, with a stem diameter of more than 75 mm (3"), when measured at 1.5 metres (5') height above ground level, in a conservation area must give the planning authority six weeks' notice of their intentions to do the work. Several exemptions from the need to notify exist including for removal of dead trees, the prevention or abatement of (legal) nuisance and for the implementation of planning permission. Work may only be undertaken either when consent has been given by the planning authority or after the six weeks has expired. As of 2012, in England and Wales penalties for cutting down or destroying a tree were upgraded to an unlimited fine [17] (previously this was a fine of up to £20,000) – and the landowner can also be required to replace the tree that was removed. For less serious offences, the penalty is a fine of up to £2,500.

Green belt (United Kingdom) British urban planning policy to maintain countryside around cities

In British town planning, the green belt is a policy for controlling urban growth. The idea is for a ring of countryside where urbanisation will be resisted for the foreseeable future, maintaining an area where agriculture, forestry and outdoor leisure can be expected to prevail. The fundamental aim of green belt policy is to prevent urban sprawl by keeping land permanently open, and consequently the most important attribute of green belts is their openness.

Site of Special Scientific Interest Protected area in the United Kingdom

A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I".

Protected areas of the United Kingdom Designated area for protection in the United Kingdom

Protected areas of the United Kingdom are areas in the United Kingdom which need and /or receive protection because of their environmental, historical or cultural value to the nation. Methods and aims of protection vary depending on the nature and importance of the resource. Protection operates at local, regional, national and international levels, and may be backed by legislation and international treaty, or less formally by planning policy.

Area of Outstanding Natural Beauty Designated area of countryside in England, Wales, and Northern Ireland

An Area of Outstanding Natural Beauty is an area of countryside in England, Wales, and Northern Ireland, that has been designated for conservation due to its significant landscape value. Areas are designated in recognition of their national importance by the relevant public body: Natural England, Natural Resources Wales, and the Northern Ireland Environment Agency respectively. In place of AONB, Scotland uses the similar national scenic area (NSA) designation. Areas of Outstanding Natural Beauty enjoy levels of protection from development similar to those of UK national parks, but unlike national parks the responsible bodies do not have their own planning powers. They also differ from national parks in their more limited opportunities for extensive outdoor recreation.

Listed building Protected historic structure in the United Kingdom

A listed building, or listed structure, is one that has been placed on one of the four statutory lists maintained by Historic England in England, Historic Environment Scotland in Scotland, Cadw in Wales, and the Northern Ireland Environment Agency in Northern Ireland.

An Article 4 direction is made by a local planning authority in the United Kingdom and exceptionally may be subject to intervention by the government. It serves to restrict permitted development rights, which means that a lot of the things people do to their land or houses without planning permission and often take for granted, are brought into the realms of planning consent. It does not in itself prohibit any action but means that a landowner is required to seek planning consent whereas without the direction this would not be necessary.

Historic preservation Preservation of items of historical significance

Historic preservation (US), heritage preservation or heritage conservation (UK), is an endeavor that seeks to preserve, conserve and protect buildings, objects, landscapes or other artifacts of historical significance. It is a philosophical concept that became popular in the twentieth century, which maintains that cities as products of centuries’ development should be obligated to protect their patrimonial legacy. The term refers specifically to the preservation of the built environment, and not to preservation of, for example, primeval forests or wilderness.

The Register of Historic Parks and Gardens of Special Historic Interest in England provides a listing and classification system for historic parks and gardens similar to that used for listed buildings. The register is managed by Historic England under the provisions of the National Heritage Act 1983. Over 1,600 sites are listed, ranging from the grounds of large stately homes to small domestic gardens, as well other designed landscapes such as town squares, public parks and cemeteries.

Development Management, formerly known as planning control, or development control, is the element of the United Kingdom's system of town and country planning through which local government or the Secretary of State, regulates land use and new building, i.e. development. It relies on a "plan-led system" whereby development plans are produced, involving various stages of public consultation prior to being adopted. Subsequently, development that requires planning permission, which is granted or refused with reference to the development plan as the starting point, then other material considerations are taken into account. The term "development management" is often abbreviated to DM.

A tree preservation order (TPO) is a part of town and country planning in the United Kingdom. A TPO is made by a local planning authority to protect specific trees or a particular area, group or woodland from deliberate damage and destruction if those trees are important for the amenity of the area. In Scotland TPOs can also be used to protect trees of historic or cultural significance. TPOs make the felling, lopping, topping, uprooting or otherwise willful damaging of trees without the permission of the local planning authority a legal offence, although different TPOs have different degrees of protection.

Historic England is an executive non-departmental public body of the British Government sponsored by the Department for Digital, Culture, Media and Sport. It is tasked with protecting the historic environment of England by preserving and listing historic buildings, scheduling ancient monuments, registering historic Parks and Gardens and by advising central and local government.

Battlefields are the final resting place for thousands of unknown soldiers, both nobles and commoners, whose lives were sacrificed in the making of the history of their country. These historic assets are an intrinsic part of a nation’s identity and consciousness. They inspire strong emotions and live on in stories, poetry and music. However, the history relating to them is often hard to unravel, as there is often little to see above ground and the historical record is usually written by the victors. The UK has many historic battlefield sites, some of which have legal protection through heritage protection legislation whilst others are protected through landscape legislation. More recently, some archaeologists prefer the term "site of conflict" to "battlefield", because of the difficulty in defining the geographical extent of a site.

Protected areas of Scotland Designated area for protection in Scotland

Many parts of Scotland are protected in accordance with a number of national and international designations because of their environmental, historical or cultural value. Protected areas can be divided according to the type of resource which each seeks to protect. NatureScot has various roles in the delivery of many environmental designations in Scotland, i.e. those aimed at protecting flora and fauna, scenic qualities and geological features. Historic Environment Scotland is responsible for designations that protect sites of historic and cultural importance. Some international designations, such as World Heritage Sites, can cover both categories of site.
