Using rural land parcel data for an agricultural site

Field parcel data is the quickest way to describe an agricultural site accurately in a planning application. Every field in an agricultural holding claiming rural payments carries a land parcel reference, made up of a map sheet reference and a parcel number, and that reference is tied to a digitised boundary and a recorded area in hectares. Quoting it, with the area, gives a case officer something checkable, and it usually matches the boundary the applicant thinks they own better than a hand-drawn line does.

It is not proof of ownership. That distinction causes more problems than any other in rural applications.

What the parcel data records

The parcel record held by the Rural Payments Agency describes land, not title. For each parcel it records the sheet and parcel reference, the digitised boundary, the total area, the eligible area for payment purposes, and land cover or land use information such as permanent grassland, arable or non-agricultural features.

Boundaries follow features on the ground: hedges, fences, ditches, tracks. They are maintained by the agency from mapping and from claimant updates, so they are current in a way that a deed plan from 1961 is not. Areas are measured to the boundary and expressed in hectares to two or three decimal places, which is exactly what a planning application form wants.

What the record does not contain: who owns the land, what tenancies exist over it, easements, rights of way as legal rights, or anything about planning history.

Finding a parcel reference for a field

If you farm the land, the references are in your rural payments account against the holding, and you can print a map showing each parcel with its reference and area. That printout is often the most useful single document in a rural application bundle.

If you do not, the practical routes are:

1. Ask the occupier or the agent, who will have the parcel schedule.
2. Use the digitised boundary datasets published through planning.data.gov.uk and the Defra MAGIC map, which let you measure area and identify constraints on the same view.
3. Take the area from a measured survey, which is what you will need anyway for anything beyond a simple building.

Record the source and the date for whichever route you use. A figure with a provenance survives scrutiny. A figure that appeared from nowhere invites a question at validation.

Using parcel boundaries on an application plan

Parcel boundaries are a good starting point for a red line, and a poor finish. Take the digitised boundary, put it on a licensed base map, then walk it. The recurring differences are a hedge that has been moved, a gateway widened, a track that has been resurfaced wider than the record, and an area of scrub that has grown into a field corner.

Where the parcel boundary and the physical boundary differ, use the physical one for the red line and explain the difference in a note. Where the application site is part of a parcel, show the part and give its area, with the parent parcel reference quoted for context.

Site area matters more than people expect, because thresholds turn on it. Half a hectare and one hectare both appear in national thresholds, so a boundary correction of a few metres can change which reports are triggered.

Agricultural land classification alongside the parcel

Parcel data tells you where the field is. It does not tell you how good the soil is, and on most rural applications the second question decides the policy argument. Habitat information sits in a separate set of layers again, which our note on reading habitat inventories covers.

The classification system grades land from 1 to 5, with grade 3 subdivided into 3a and 3b, and best and most versatile land means grades 1, 2 and 3a. National policy expects poorer quality land to be used in preference to higher quality, so a scheme on grade 2 land needs a different justification from one on grade 4.

The national maps published by Natural England are provisional and drawn at a broad scale, useful for screening and not for determination. Where the grade matters, a site-specific survey following the published guidelines, carried out by a soil scientist with augered profiles at a stated density, is what a consultee will expect. An Agricultural Land Classification assessment is a survey-based document, and councils normally expect a suitably qualified author, with professional review strongly advised. Surveying is limited by ground conditions, so waterlogged winter fields are a problem.

Evidence of agricultural use for prior approval

For a barn conversion under the agricultural to residential permitted development route, the use history of the building is the gateway condition. The building must have been used solely for agriculture as part of an established agricultural unit on the relevant date set in the Order, or, where it came into use later, for the period the Order specifies before the application.

Parcel and holding records help to establish that use, alongside other material:

• the parcel schedule and holding records showing the land in agricultural use in the relevant years
• payment scheme records for the holding
• livestock movement records, spraying records and feed or fertiliser invoices
• dated aerial imagery showing the building in agricultural use
• a statutory declaration from the person who farmed it, supported by the above

The prior approval route is a technical, condition-by-condition test rather than a merits judgement, so a well organised evidence bundle matters more than argument. And where the agricultural unit's size is the point, parcel areas add up to the figure the permitted development classes for agricultural buildings turn on.

Where the data does not match the deeds

It frequently does not. Parcel records reflect occupation and cultivation. Title reflects ownership. A tenant's parcel may cross two titles. A landowner may own a strip that has been farmed by a neighbour for twenty years. A track shown as part of one parcel may be a shared access with rights recorded in another title.

For a planning application, this matters for the ownership certificates. The certificate has to reflect who owns the application site, and getting it wrong is a serious defect rather than an administrative one. So take title from the registered title plan, take physical extent from survey or parcel data, and reconcile the two before you complete the form. Where there is an agricultural tenancy, the agricultural holdings notice on the form has to be completed as well.

Public rights of way are a further layer that parcel data does not carry, and the definitive map is the source, as our note on checking the definitive map explains.

Limits of the data as evidence

Be honest about what you are using it for. Parcel data is good evidence of the physical extent of a field, its area, and its recorded agricultural land cover over time. It is weak evidence of ownership, of the lawful planning use of a building, and of anything about boundaries in a dispute.

In a case officer's hands it is a cross-check. Used that way, quoting the reference and the area, it makes the application look like it was prepared by someone who knows the holding. Used as a substitute for title or survey, it produces an invalid certificate.
