Non-designated heritage assets and the local list
Local listing creates no new consent requirement. It creates a balanced judgement on the scale of harm against the asset's significance, and that judgement turns on the evidence you supply.
A non-designated heritage asset is a building, monument, site, place, area or landscape that a local planning authority has identified as having heritage significance, but which is not listed, scheduled, or registered. Locally listed buildings are the most familiar example. The practical effect is narrow and specific: no extra consent is required, but the effect of your proposal on the asset's significance is a material consideration, and the Framework requires a balanced judgement having regard to the scale of harm or loss and the significance of the asset.
That balanced judgement is the whole of the test. It is not the statutory duty that applies to listed buildings, and it is not the strong presumption that applies in conservation areas.
What makes an asset non-designated but material
Three routes bring an asset into this category.
The first is a formal local list, adopted by the council after consultation and published as a schedule with a map. The second is identification through the plan-making process, where a local plan or neighbourhood plan names buildings or areas of local heritage interest. The third, and the one consultants forget, is identification during the determination of an application, where the council concludes on the evidence that a building has heritage significance even though it appears on no list.
That third route is legitimate. Councils have used it on undesignated archaeology and on buildings that were simply never assessed. It also cuts the other way: appearing on a local list does not oblige an officer to find that a particular proposal causes harm.
Non-designated archaeological interest works slightly differently. Where a site holds archaeological interest of demonstrably equivalent significance to a scheduled monument, national policy expects it to be considered under the policies for designated assets. That is a high bar, and it is usually reached through evaluation rather than assertion.
How councils compile and consult on local lists
Most authorities follow a similar process, and knowing it tells you how much weight the list carries.
- Selection criteria are adopted, usually covering age, rarity, architectural interest, group value, archaeological interest, historic association, landmark quality and social or communal value.
- Nominations are invited from the public, amenity societies and parish councils, with a proforma.
- Officers or a heritage panel assess each nomination against the criteria and prepare a short citation.
- The draft list goes out to consultation, including to owners, though notification practice varies.
- The list is adopted by committee, sometimes as part of a supplementary planning document.
A list adopted with published criteria, citations and consultation carries meaningful weight. A list inherited from a 1990s local plan with no citations carries less, because nobody can tell what the significance was thought to be. Ask for the citation. If none exists, say so in your heritage statement, politely.
Local listing does not remove permitted development rights and does not create a consent requirement of its own. Rights are removed only by an Article 4 direction, which councils sometimes make over locally listed buildings but often do not.
The balanced judgement the Framework requires
The Framework asks the decision-maker to take the effect on significance into account, and, where the proposal directly or indirectly affects a non-designated heritage asset, to make a balanced judgement having regard to the scale of harm or loss and to the significance of the asset. The current edition was published on 17 August 2026 and uses policy codes rather than paragraph numbers, so cite it by code and check the wording as published.
Two things follow for anyone drafting.
There is no separate public benefits test as there is for designated assets. The harm is one consideration in the overall planning balance, weighed with everything else. In practice officers often import the language of the designated tests, and a well-argued statement can push back on that.
And the weight given to the harm scales with significance. Total loss of a building of clear local architectural interest weighs more heavily than the replacement of unsympathetic modern windows on the same building. Say which end of that range you are at, and why.
Evidencing significance
The Framework expects applicants to describe the significance of any heritage asset affected, including any contribution made by setting, to a level of detail proportionate to the asset's importance. Proportionate is the operative word. A locally listed cottage does not need a fifty-page document.
A workable evidence base for a non-designated asset is usually:
- The council's citation, if one exists, and the criteria it was assessed against.
- Historic mapping, showing the building's development and its relationship to what surrounds it.
- The Historic Environment Record entry, obtained from the county archaeologist, which frequently holds more than the local list does.
- A measured or annotated photographic record of the elements that carry the significance, whether that is a roof structure, a shopfront, a chimney or a boundary wall.
- A short statement of significance written against the standard headings of architectural, historic, archaeological and artistic interest.
That material sits naturally in a Heritage Statement, which is the document councils ask for and read. Where the proposal involves loss, a fuller record may be conditioned. Our note on how to read a council validation checklist covers where these requirements are set out locally.
Where non-designated status changes the report bundle
The status itself adds one document and sometimes two.
| Situation | Usual requirement |
|---|---|
| Alteration or extension of a locally listed building | Heritage statement with a statement of significance |
| Demolition or substantial loss | Heritage statement plus a recording condition |
| Site with non-designated archaeological interest | Desk-based assessment, then possible evaluation |
| Building of clear architectural interest being lost | Written and photographic record before works |
A Historic Building Recording exercise is typically secured by condition rather than required with the application, and the level, following Historic England's levels 1 to 4, is set by the officer according to the interest of the building. Where the asset is archaeological rather than built, an Archaeological Desk-Based Assessment comes first and normally determines whether trial trenching follows.
Councils usually expect a suitably qualified author for these documents, and professional review is strongly advised.
Illustrative case: a Victorian outbuilding on a local list
Illustrative example. A former coach house behind a Victorian villa, locally listed for group value with the main house and for its brickwork and cart entrance, proposed for conversion to a two-bedroom dwelling with a new opening in the rear elevation.
The statement of significance identifies the cart entrance, the roof structure and the brick bond as the elements carrying interest, and the yard relationship as the group value. The proposal retains the cart entrance as a glazed feature, keeps the roof structure exposed, and places the new opening on the rear elevation away from the yard. The harm is limited and is confined to the rear.
Set against that, the public benefits are the repair of a building on a council's at-risk register and the use of previously developed land. On those facts, the balanced judgement tends towards approval. Change one variable, put the new opening on the yard elevation, and the recommendation may change with it. The decision remains the council's.

Frequently asked questions
Does local listing require listed building consent?
No. Local listing is not a statutory designation, so there is no separate consent regime and no listed building consent application. What changes is that the effect of your proposal on the asset's significance becomes a material consideration, assessed as a balanced judgement in the planning decision alongside everything else.
Can a council treat a building as a heritage asset if it is not on any list?
Yes. National policy defines heritage assets to include those identified by the local planning authority, and identification can happen during determination of an application on the evidence before the officer. That route is used for undesignated archaeology and for buildings never formally assessed, so a blank local list is not the end of the question.
How detailed does a statement of significance need to be?
Proportionate to the importance of the asset. For a locally listed cottage a few pages covering architectural, historic, archaeological and artistic interest, with historic mapping and a photographic record, is normally enough. Councils expect the level of detail to match the interest, and an over-long document does not improve the balanced judgement.
Are permitted development rights affected by local listing?
Not by the listing itself. Permitted development rights are removed only by an Article 4 direction or by a condition on an earlier permission. Councils sometimes make Article 4 directions covering locally listed buildings, particularly for front elevations and windows, so check the council's Article 4 register rather than assuming.
What is the difference for non-designated archaeology?
Where a site holds archaeological interest of demonstrably equivalent significance to a scheduled monument, national policy expects the designated asset policies to apply instead of the balanced judgement. That is a high threshold reached through desk-based assessment and evaluation rather than assertion, and the county archaeologist normally advises on it.
