Permitted development


[edit] Introduction

Generally it is up to a local planning authority to decide whether to allow a particular development or not. However, in England and Wales, the Town and Country Planning (General Permitted Development) Order 1995 enables central government to permit certain types of developments known as permitted developments.

These are generally minor changes to existing properties. Permitted developments do not require approval from the local planning authority as permission is granted by the Order.

Examples of permitted developments are:

[edit] Restrictions

There are a great number of complex and detailed restrictions and conditions on each of these permitted development classes. See Planning Portal: Permitted development for householders for detailed guidance for householders.

There are further restrictions for certain areas and building types:

In addition, local authorities are able to remove permitted development rights (PDR) that are of particular significance given the character of an area by issuing an Article 4 Direction.

There may also be conditions on existing permissions preventing certain types of development.

In certain cases, even though a development is permitted, prior approval of some issues is required from the local authority. This includes:

See Prior approval for more information.

This means that establishing whether a proposal constitutes a permitted development or not is considerably more complicated than it may at first seem. Often the best way to determine whether a development is permitted or not is to ask the local planning authority. This can be done by asking for a ‘lawful development certificate’ for which a fee will be charged.

[edit] Policy changes

[edit] 2013

In May 2013, the Town and Country Planning (General Permitted Development) (Amendment) (England) Order 2013 came into force, making changes to permitted development rights. These amendments include making it easier to change between certain use classes, and permitting larger extensions to domestic and commercial premises. Some of these amendments permit development only with prior approval of certain aspects or beyond certain sizes.

Following this amendment, some local authorities have introduced article 4 directions, in particular to prevent change of use class from office to residential use. It has yet to be seen whether the Secretary of State will allow these directions to stand.

Further changes are proposed to permitted development rights, to give greater flexibility to changes of use, allowing:

However, following concerns that there would be a spate of agricultural building conversions in National Parks and Areas of Outstanding National Beauty, Planning Minister Nick Boles stated:

“...the intention behind the proposed permitted developed right is to bring forward more housing on land that is already developed, and to make maximum use of the buildings that our ancestors saw fit to build, so that we do not have to put up any more buildings on green fields than is necessary to meet our housing and other needs....I recognise, however, and the Government recognise, that national parks and AONBs are so called for a reason and have a special status. It is a status we must respect, and it is important that we think hard and listen to the arguments put to us about the appropriateness of this measure in those areas." (ref. Hansard 26 February 2014.)

[edit] 2014

In March 2014, the Chancellor’s 2014 budget announced a further review of the General Permitted Development Order, to create ‘…a three-tier system to decide the appropriate level of permission, using permitted development rights for small-scale changes, prior approval rights for development requiring consideration of specific issues, and planning permission for the largest scale development.’

He also announced fresh consultation to assess:

On 31 July 2014, Brandon Lewis, newly-appointed Minister of State for Housing and Planning at the Department for Communities and Local Government (DCLG), announced proposals to make the temporary permitted development rights that allow offices to be converted into new homes permanent. In 2016, The Department for Communities and Local Government then laid before Parliament regulations to make this permanent from 6 April 2016.

Lewis also proposed making it easier to convert empty and redundant buildings into new homes and to ensure planning conditions are cleared on time so that new homes that have planning permission can be built without delay. (Ref. DCLG, Making the planning system work more efficiently and effectively, Giving communities more power in planning local development, 31 July 2014.)

[edit] 2016

In April 2016, the government published Permitted development rights for householders: technical guidance to help householders understand the detailed rules on permitted development and the terms used.

[edit] 2018

In May 2018, the government announced a consultation about whether the early stages of shale exploration (fracking) should be treated as permitted development, and the circumstances in which this might be appropriate. Ref

[edit] 2019

In May 2019, following a consultation; Planning reforms – supporting the high street and increasing the delivery of new homes, the government announced that permitted development rights allowing increased size limits for single-storey rear extensions would be made permanent.

[edit] 2020

On 9 April 2020, a time-limited permitted development right was brought into force in response to the Coronavirus outbreak. This introduced wide-ranging powers allowing emergency construction of, or change of use to, medical facilities and related residential accommodation. Ref

In June 2020, the regulations were amended to ensure that new homes developed through permitted development rights provide adequate natural light for the occupants. Ref

On 21 July 2020, Housing Secretary Robert Jenrick announced new laws laid in Parliament meaning full planning applications will not be required to demolish and rebuild unused buildings as homes and commercial and retail properties can be quickly repurposed to help revive our high streets and town centres. Homeowners will also be able to add up to 2 additional storeys to their home to create new homes or more living space through a fast track approval process. The rules are due to come into effect in September 2020. Ref

On 30 September 2020 Housing Secretary Robert Jenrick announced that new homes delivered through permitted development rights would have to meet the Nationally Described Space Standard. This begins at 37m² of floorspace for a new one bed flat with a shower room. Ref

On 30 December 2020, Chandru Dissanayeke Director, Building Safety Programme for the Ministry of Housing, Communities & Local Government published a letter to Local Planning Authorities in England to inform them of an amendment to the Town and Country Planning (General Permitted Development) (England) Order 2015 (“the GPDO”).

The amendment introduces an additional matter for prior approval to two permitted development rights which allow extra storeys to be added to existing buildings. These rights are: Class A new dwellinghouses on detached blocks of flats and Class AA new dwellinghouses on detached buildings in commercial or mixed use of Part 20 to the Order.

This change requires a developer seeking prior approval under those classes in relation to an existing building, which is 18 metres or more in height, to provide a report from a chartered engineer or other competent professional confirming that the external wall construction of the existing building complies with paragraph B4(1) of Schedule 1 to the Building Regulations 2010 (S.I. 2010/2214) to the local planning authority. The purpose of this report is to confirm that the external walls of the building will adequately resist the spread of fire over the walls and from one building to another, having regard to the height, use and position of the building.

I had planning permission but I didn't need building regs for my new garage, it is now finished, what do i do now? Do I have to notify anyone

I don't believe there is any obligation to inform the planning authority when a development is complete, unless there are conditions attached that relate to completion - but it would be worth phoning them to verify this.
