Class A – new agricultural buildings on units of 5 ha or more / Private Ways / Other operations

Class A of Part 6 is the main agricultural permitted development right for units of 5 hectares or more. It can permit new agricultural buildings, extensions and alterations, private ways, excavations and engineering operations where the development is reasonably necessary for agriculture within the unit and all of the detailed limitations and conditions are met.

New buildings and several other types of Class A development use the agricultural prior notification procedure before work starts. The procedure is explained below.

Before using Class A, check our guides to agricultural land, agricultural units and Paragraph D.

If development is proposed on a separate parcel forming part of the unit, that parcel must be at least 1 hectare in area. The agricultural unit as a whole must be 5 hectares or more.

Forestry land does not automatically count towards that 5-hectare agricultural unit. Woodland is agricultural for planning purposes where its woodland use is ancillary to farming land for other agricultural purposes. A separate block whose primary use has become forestry should normally be treated as forestry land instead. See the Part 6 overview for the agriculture-versus-forestry boundary.

 

 

Note that you cannot benefit from a new agricultural building or the extension thereof if you have taken advantage of Class Q or Class S of Part 3 involving conversion of previous agricultural building etc. to residential or a school on the same agricultural unit – if the EAU has changed, this may be okay, but ensure you have evidence to show that the two are not linked. If in doubt, take advice. Conversion of a barn under Class R to a flexible commercial use, does not prevent a new agricultural building erection.

Part 6 today can also affect Class Q tomorrow. Under the current Class Q rules, development under Class A(a) or Class B(a) on the established agricultural unit during the previous 10 years prevents Class Q being used. If there is any realistic prospect of converting an agricultural building to residential use, it is worth checking that strategy before carrying out a new Class A building or extension.

Any new agricultural building must be for agricultural purposes only and must be reasonably necessary for agriculture and can’t be used for any dwelling. If somebody genuinely needs to live on or close to the holding, that is a separate planning route – see our guide to rural workers’ dwellings and agricultural occupancy ties.

You can erect or enlarge agricultural buildings up to the Class A ground-area limits explained below. A new agricultural building can generally be up to 1,500 sq m, while a building for accommodating livestock remains limited to 1,000 sq m. The normal maximum height is 12 metres, reduced to 3 metres within 3 kilometres of the perimeter of an aerodrome. No part of the development can be within 25 metres of the metalled part of a trunk road or classified road. The separate livestock and protected-building rules are explained below.

A 2026 Cheshire Part 6 appeal shows why the aerodrome restriction can catch more than a conventional airport. The Inspector treated a nearby licensed helipad as an aerodrome for this purpose, so a building over 3 metres could not rely on Class A.

Any works must be reasonably necessary for the purposes of agriculture within the unit. The scale of the development may therefore need to be justified against the agricultural operation. For Part 6, agricultural land must already be in use for agriculture for the purposes of a trade or business; hobby or purely domestic use is not enough.

The Alkham Part 6 appeal, 6009974, is a useful reminder that the GPDO does not impose a rigid profitability or accounts test when deciding whether agriculture is being carried on for the purposes of a trade or business. The Inspector considered the evidence in the round: the 13-hectare holding, Natural England stewardship arrangements, seeded and subdivided grazing land, invoices for additional ewes, sheep seen on the land and the agricultural vehicles and machinery kept at the farm. The absence of commercial profitability information was not decisive.

Reasonable necessity is also not frozen at the current size of an agricultural operation. On the evidence in Alkham, the Inspector accepted that realistic growth in the flock could properly be considered when assessing the need for the proposed building. That does not remove the need for evidence; it means the assessment is not restricted to a snapshot of existing livestock numbers.

For development which is otherwise permitted, condition A.2(1)(a) controls the use of development within 400 metres and paragraph D.1(3) supplies limited circumstances for livestock. But that condition does not override the separate A.1(i) bar on erecting or constructing a new livestock building within 400 metres, as Marshall confirms. The Alkham Inspector relied on D.1(3) for the lambing and newly-born-animal use but did not appear to address A.1(i), so that appeal should not be treated as authority that a new livestock building within 400 metres is permitted development.

Any building, structure or excavation used or to be used for accommodating livestock, or for storing slurry or sewage sludge, must not be within 400 metres of the curtilage of a protected building. That term is wider than just a dwelling: it means a permanent building normally occupied by people, or which would be occupied if used for its designed purpose. It excludes buildings within the agricultural unit and a dwelling or other building on another agricultural unit used for or in connection with agriculture. Separate 400-metre restrictions also apply to certain biomass boiler and anaerobic digestion buildings.

Whilst you can build a barn of up to 1,500 sq m, this might be limited by any other structure, works, plant, machinery, ponds or tanks within the same agricultural unit which are being provided or have been provided within the preceding 2 years and any part of which would be within 90 metres of the proposed development. So in other words you need to take into account any other development within 90m of the new barn in the previous 2 years. If you are beyond 90m you can ignore those.

Note any development under Class A must be at least 25m from the metalled part of a trunk or classified road. Metalled part refers to a road with a hard durable surface such as cement, concrete or tar. An unmade road of mud and gravel would not be metalled. Metalled comes from the Latin word ‘metallum’ meaning quarry. The earliest roads would have been quarried stone built by the Romans. It has nothing to do with metal. So now you know!

Whether we can claim a road of potholes is still metalled is another question!!

 

 

What else can Class A cover besides a barn?

Class A is wider than new agricultural buildings. It also permits excavation and engineering operations that are reasonably necessary for agriculture within the unit. That can be important for the practical infrastructure of a working farm.

Depending on the facts, Class A can potentially cover works such as:

• farm tracks and other private ways
• hardstanding, yards and aprons where these amount to agricultural engineering works
• plant and machinery installed as part of engineering operations
• agricultural drainage, irrigation and service works, including pipes, cables and similar apparatus where they amount to engineering operations
• excavations, earthworks and ponds
• depositing material as part of agricultural works
• placing or assembling a tank in water, including fish-farming tanks or cages

These are not blanket permissions. The works must genuinely fall within the excavation or engineering limb of Class A and be reasonably necessary for agriculture within the unit. Some categories also have their own specific limitations and prior approval triggers.

Plant and machinery

Where Class A engineering operations involve plant or machinery, the 1,000 square metre ground-area limit in A.1(e)(i) can apply. The Paragraph D calculation also takes account of specified development within the preceding 2 years where any part lies within 90 metres of the proposal. The normal height limit for buildings, structures and works is 12 metres, reduced to 3 metres within 3 kilometres of the perimeter of an aerodrome.

Hard surfaces, excavations and earthworks

The GPDO expressly contemplates the provision of a hard surface within Class A. A hardstanding does not automatically require prior approval simply because it is a hard surface. However, if it forms or alters a private way, the private-way prior approval procedure applies.

Excavations and the deposit of waste material have a separate trigger. Where the relevant area exceeds 0.5 hectares, prior notification is required as to the siting. The 0.5 hectare calculation is cumulative: it includes the proposed excavation or deposit together with other unfilled excavations and areas of waste deposited and not removed within the agricultural unit. This is a different calculation from the 2-year and 90-metre rule used elsewhere in Paragraph D.

Waste material and material dug from the farm

Class A is not a general permission to import and tip waste. Waste material brought onto the holding from elsewhere can only be deposited where it is for use in Class A(a) building works or in providing a hard surface, and it must be incorporated into those works straight away.

Where Class A works involve extracting mineral from the land, including from a disused railway embankment or mineral-working deposit, the extracted mineral must not be moved off the agricultural unit. A separate mineral-working operation should be considered under Class C rather than treating Class A as a general quarrying right.

Tanks and fish farming

The placing or assembly of a tank in any waters is one of the Class A operations which requires prior notification. Paragraph D treats a tank as including a cage or other structure used for fish farming. On Article 2(4) land, excavations or engineering operations connected with fish farming are not permitted by Class A.

Biomass, anaerobic digestion and hydro power

Paragraph D expressly provides that a Class A building can be reasonably necessary for agriculture where it is used to house a biomass boiler, anaerobic digestion system or hydro-turbine, or for associated fuel or waste storage. That does not create an unrestricted renewable-energy right: the other Class A limits still apply, including the 400 metre restrictions and the rules about where fuel and waste may come from.

 

New agricultural barns in AONB, National Parks, Conservation areas etc.

 

Class A is not prevented or restricted within Article 2(3) land which is Conservation Areas, National Landscapes (AONB), or World Heritage Sites. On Article 2(4) land, which includes National Parks and The Broads, Class A does not permit excavations or engineering operations connected with fish farming on or over Article 2(4) land.

The 0.5 hectare threshold in Class A does not create a general exemption for ponds or hardstanding. It applies to excavations and the deposit of waste material for the purposes of the prior approval procedure, using the statutory definition of the relevant area in Paragraph D. A smaller excavation may therefore avoid that particular prior approval trigger, but the other Class A limitations and conditions still apply. On Article 2(4) land, excavations or engineering operations connected with fish farming are not permitted development under Class A.

 

 

Private roads

 

You can construct a private agricultural way on a separate parcel of at least 1 hectare, provided the agricultural unit as a whole is 5 hectares or more. No part of the development can be within 25 metres of the metalled part of a trunk road or classified road (check Find My Street to establish).

If the development forms or alters a private way, you must apply to the local planning authority before starting so that it can determine whether its prior approval is required as to the siting and means of construction. There is no 0.5 hectare exemption for a private way. A new surfaced farm track created where no surfaced route previously existed will normally amount to the formation of a private way.

A private road or private way must be reasonably necessary for agriculture within the unit. A hard surface does not automatically require prior approval simply because it is being laid. The 0.5 hectare threshold in A.2(2)(c) applies to excavations and the deposit of waste material, not to hardstanding as such. However, if the hard surface itself forms or alters a private way, the Part 6 prior approval procedure applies regardless of its area. Where the works are only a hardstanding or apron and do not amount to a private way, a proposed certificate of lawfulness can be useful if formal confirmation is wanted.

Taylor & Sons (Farms) v Secretary of State [2001] EWCA Civ 1254 is a useful reminder that hardstanding and a farm track can raise separate Part 6 questions. In that case the absence of compliance with the private-way procedure was a separate reason why the track could not rely on Class A.

A new field entrance can be permitted development under Class B of Part 2 where the highway is neither a trunk road nor a classified road and the access is required in connection with development permitted by another Class in Schedule 2, other than Class A of Part 2. This planning permission does not give a right to carry out works on land owned or controlled by somebody else. If the access crosses or alters highway land, a verge or a footway, separate consent from the highway authority may be required.

If you need to erect a new fence, this is covered under Class A of Part 2. This is limited to 1m in height against a highway used by vehicles.

There is no standalone maximum ground area for a private way under Class A. The separate 1,000 sq m and 1,500 sq m limits in A.1(e), and the 2-year/90-metre calculation in Paragraph D, apply to the particular categories of development specified there; they should not be treated as a general size cap on a farm track.

 If the primary purpose of the new track, or the proposed work to the track is not ‘reasonably necessary’ for the purposes of agriculture then planning permission will be required.

Class E of Part 9 permits a developer to carry out maintenance or improvement of an existing un-adopted street or private way as permitted development not requiring planning permission or prior approval. There is no statutory definition of what constitutes ‘maintenance or improvement’.  It is a matter of fact and degree, and open to the Local Planning Authority’s interpretation. There is no requirement for this work to be reasonably necessary for the purposes of agriculture or forestry as there is in relation to Part 6 of the GPDO.

 

 

Prior Approval? 

 

For the erection of a new agricultural building, or the formation or alteration of a private way, you must apply to the local planning authority before starting so that it can determine whether its prior approval is required. This is often described as an agricultural prior notification. Prior approval itself is not automatic: the first question is whether the authority requires it. If you need assistance, please contact us.

There is an exception for some extensions or alterations of existing agricultural buildings. If the building is not on Article 2(4) land, the prior approval procedure does not apply unless the extension or alteration is significant. A significant extension or alteration is one where the cubic content of the original building would be exceeded by more than 10%, or the height would exceed the height of the original building. On Article 2(4) land, the exception does not apply.

The first stage is a 28-day process. The period runs from the date the local planning authority receives the application required by A.2(2), including the written description, materials, plan and any required fee. Within that period the authority can notify you that prior approval is not required, or that prior approval is required. If it says prior approval is not required, the development can begin in accordance with the submitted details. If it says prior approval is required, you must wait for that approval before starting.

If the authority decides that prior approval is required, that moves the proposal into the second stage. The authority then considers only the matters allowed by Class A: for a building, its siting, design and external appearance; for a private way, its siting and means of construction; for an excavation or deposit, its siting; and for a tank, its siting and appearance. Prior approval can then be granted or refused.

If the 28 days expires without the authority determining whether prior approval is required or notifying you of its determination, A.2(2)(iii)(cc) allows the development to begin. It is sensible to write to the authority before starting and record that the 28-day period has expired. The development must still comply fully with Class A, including the requirement that it is reasonably necessary for agriculture within the unit, and it must be carried out in accordance with the details submitted.

 

If Prior Approval is Required?

 

If Prior Approval is required, then the applicant must display the notice on the land for at least 21 days in a 28 day period from the date of notice. The site notice is part of the prior approval procedure; displaying it does not itself authorise the development to begin. Where prior approval is required, work must wait until that approval has been given and must then be carried out in accordance with the approved details. It is sensible to keep dated photographs showing that the site notice remained displayed for the required period. 

Where the development is the erection, extension or alteration of a building under Class A(a), the developer must notify the local planning authority in writing within 7 days of substantial completion. This completion notice is required whether or not prior approval was needed.

Development caught by A.2(2) must normally be completed within 5 years. Where prior approval is given, the 5 years runs from the date of approval; in other cases it runs from the date the required information was given to the local planning authority. Unless the authority agrees otherwise in writing, the development must follow the approved details where prior approval was required, or the submitted details where it was not.

 

Significant extensions and what happens if farming stops

A significant extension or significant alteration can only be carried out once under Class A(a). For Part 6, significant means increasing the original building’s cubic content by more than 10%, or increasing its height.

There is also a long-term restoration condition. If a new building, significant extension or significant alteration stops being used for agriculture within the unit within 10 years of substantial completion, and planning permission for another use is not obtained within the following 3 years, the building or extension may have to be removed and the land restored unless the local planning authority agrees otherwise in writing.

This makes it worth keeping the prior notification, completion notice and later planning history together rather than treating the Part 6 approval as a one-off piece of paperwork.

 

Livestock

 

If a building, structure or excavation is within 400 metres of the curtilage of a protected building, Class A does not allow it to be provided for the ordinary accommodation of livestock. The protected-building test is wider than residential dwellings alone. Where the livestock limitation applies, any later use of development carried out under Class A for accommodating livestock is also restricted, subject only to the limited emergency and temporary circumstances in Paragraph D.1(3). A new building for accommodating livestock is limited to 1,000 sq m.

Livestock buildings can also raise a separate ecological air-quality issue because of ammonia and nitrogen deposition, particularly where a sensitive SSSI or habitats site is nearby. See our guide to air pollution and protected sites.

Provided there isn’t another suitable building more than 400m from the curtilage of a protected building, available to accommodate the livestock you might be able to use the building for livestock in certain limited emergency circumstances.

This exemption would include in the event of quarantine requirements, or an emergency due to another building or structure in which the livestock could otherwise be accommodated being unavailable because it has been damaged or destroyed by fire, flood or storm; or animals need temporary accommodation in a building or other structure because they are sick or giving birth or newly born, or to provide shelter against extreme weather conditions.

 

Increased size from May 2024

 

As from 21st May 2024, Class A was updated to allow for barns to be erected or enlarged up to 1,500 sq m from the previous 1,000 sq m. If you are however planning on using the barn for livestock, this remains at 1,000 sq m.

Also from 21st May 2024, Class A no longer permits the erection or extension of a building on land or a building that is, or is within the curtilage of, a scheduled monument. A transitional period applied to certain previously permitted development until 20th May 2025, but that period has now expired.

 

 

Can I build a new agricultural barn under permitted development in Wales?

On an agricultural unit of 5 hectares or more in Wales, Class A may allow the erection of a new agricultural barn on agricultural land within the unit, provided the building is reasonably necessary for the purposes of agriculture within that unit.

A new barn will not be permitted development under Class A if, for example:

• it would be built on a separate parcel of land within the agricultural unit that is less than 1 hectare;
• the relevant ground area would exceed 465 square metres;
• any part would exceed 3 metres in height within 3 kilometres of an aerodrome or 12 metres elsewhere; or
• any part of the development would be within 25 metres of the metalled part of a trunk road or classified road

Because a new barn is the erection of a building, the development also falls within the prior approval procedure before work starts. For a new agricultural building, the local planning authority can consider the siting, design and external appearance of the barn.

In practice, that means a new barn is often possible under Class A on a unit of 5 hectares or more, but only where it is a proper agricultural building, genuinely needed for the agricultural operation, and compliant with the size, height and location limits in the legislation.

Other Agricultural Sections

 

Paragraph D / Legislation (England)

 

Whilst Class A does allow for new agricultural buildings on units of 5 hectares or more, it is suggested that you ensure that you comply with the current legislation which is detailed below. If unsure book a zoom session with Ian.

Paragraph D refers to agricultural land as land which, before development permitted by this Part is carried out, is land in use for agriculture and which is so used for the purposes of a trade or business, and excludes any dwellinghouse or garden; See more on this page.

Paragraph D refers to “agricultural unit” meaning agricultural land which is occupied as a unit for the purposes of agriculture, including: (a) any dwelling or other building on that land occupied for the purpose of farming the land by the person who occupies the unit, or (b) any dwelling on that land occupied by a farmworker; See more on this page.

Paragraph D contains various other definitions for terms used in Classes A, B & C of Part 6 and should therefore be read in conjunction with this class.

Paragraph D refers to a protected building as any permanent building which is normally occupied by people or would be so occupied, if it were in use for purposes for which it is designed; but does not include:
(a) a building within the agricultural unit; or
(b) a dwelling or other building on another agricultural unit which is used for or in connection with agriculture;

Paragraph D refers to a “significant extension” or “significant alteration” meaning any extension or alteration, as the case may be, of the building where the cubic content of the original building would be exceeded by more than 10% or the height of the building as extended or altered would exceed the height of the original building; For this you will need prior approval.
